How To Install A Tankless Hot Water Heater

How to Install a Tankless Water Heater

Instructions from a professional on how to remove an old water heater tank, prepare the area for installation of a tankless water heater, and finally install the tankless water heater Because it does not store a huge amount of heated water, a tankless water heater, also known as an on-demand water heater, saves money over a traditional water heater. Essentially, it serves to give hot water on demand, so you won’t have to worry about the shower suddenly being chilly. The process of installing a gas tankless water heater consists of mounting the unit, connecting the gas and water lines, and installing a flue.

Therefore, it may not function well in a family where two or three showers may be operating at the same time, as an example.

It is both small and very efficient to use a tankless water heater.

The following skills are required if you opt to conduct the task yourself: shutting off the water to your house (seeHow to Shut Off the Water to Fixtures) and cutting into and connecting new fittings and pipes to your supply pipes (if you have copper pipes, seeCuttingJoining Copper Pipe).

There is also the need for a gas line and an electrical connection to a 120-volt circuit.

It is not necessary to vent an indoor electric tankless water heater to the outdoors because it is contained within the home.

It may either be hooked into a 240-volt outlet or directly attached to a power source such as a generator.

Tankless Water Heater Preparation

Remember to complete all essential preparations before disconnecting and removing your present water heater; you don’t want to be without hot water for a week or two while you wait for any plumbing, electrical, or vent work to be completed. If you are installing a new gas unit, you should determine whether you need to upgrade your gas meter. Because the unit consumes a considerable amount of BTUs, it is possible that your meter does not have the capacity to feed it in addition to the other gas-using appliances in your home.

  • Request that the gas provider inspect your new unit to ensure that it is receiving the appropriate amount of manifold pressure for it.
  • It is better to employ a professional plumber to install a new gas line if you need to replace an existing one.
  • This will save you time and money.
  • The fact that a tankless water heater generates a significant amount of condensation and pushes air out with a fan necessitates the installation of category II stainless-steel exhaust pipe with firmly sealed silicon joints, as seen in the second video below.
  • A damper is an excellent addition for those who live in colder climates since it prevents chilly air from re-entering the home.
  • Floor drains and utility sinks should be used to dispose of the excess liquid.
  • In addition to gas, a gas unit requires 120-volt electrical power.
  • You can watch this wonderful video from This Old House, which will provide you with an excellent explanation of the many stages involved in installing a tankless water heater.
  • He makes the decision to remove and replace his malfunctioning water heater with a tankless water heater, and he guides us through the entire procedure with his hands on assistance.
  • Codes demand that a subpanel (which may or may not be included with the unit) be erected next to the unit in order to comply.

Connect the wire to the subpanel and then from the subpanel to the unit, starting at the unit. It is essential that the electricity to the water heater’s circuit is turned off at all times while the work is being performed. +Find a Water Heater Installation Specialist in Your Area

Removing the Old Water Heater

Remember to complete all essential preparations before disconnecting and removing your present water heater; you don’t want to be without hot water for a week or two while you wait for necessary plumbing, electrical, and vent work to be completed. As part of the installation of a new gas unit, you should check to determine if you need to upgrade your gas meter. It’s possible that your meter doesn’t have the capacity to feed the unit, as well as the other gas-using appliances in your home, because the device consumes a considerable amount of BTUs.

  • Have the gas provider check to verify that it is supplying the proper amount of manifold pressure for your new unit, as well.
  • For any gas line installation work, it is recommended that you contract with an experienced plumber.
  • Venting will be required for an inside gas unit as well.
  • The plastic pipe seen in the This Old House movie below may be appropriate for use with a high-efficiency tankless water heater, as demonstrated in the video above.
  • Installing a condensate drain on your heater, depending on the manufacturer and type, will drain the water from condensation through a plastic tubing connection.
  • All plumbing and venting requirements should be determined by consulting the manufacturer’s documentation.
  • Plan to either connect it into a nearby outlet or wire it straight to a junction box to keep it from becoming damaged.
  • This in-depth video, produced by Ron Hazelton, describes how a failed conventional water heater can result in debris in your water, which can clog faucet aerators, shower heads, and other water-using equipment in your house.
  • It is recommended that you hire an electrician if you are installing an electric water heater that requires 240-volt electrical power unless you are confident in your abilities.
  • With its own circuit breakers, you may immediately withdraw power from the device if the situation calls for it, as this subpanel has.

It is essential that the electricity to the water heater’s circuit be turned off at all times while the repair is being performed. Water heater installation professionals might be found in your neighborhood.

Installing a Tankless Water Heater

Tankless units can be fitted flush against the wall (against the drywall or plaster), or they can be inserted into the wall between the studs. Using a stud finder, identify the studs in the wall where you want to install the unit, and then cut a hole between each of them. Attach the item to the wall in accordance with the manufacturer’s recommendations. Water supply pipes should be routed to the water heater. Make certain that the pipe from the water utility is linked to the inlet and that the pipe flowing to the home is connected to the outlet before starting the project.

  • You might also want to consider installing a pressure-relief valve.
  • The water valves should be opened, but not those for the power or gas.
  • Close the water valves and turn off the water.
  • Replace the filter, turn on the water valves, turn on the electrical power, and turn on the gas valves if necessary.

How to Install or Replace a Tankless Water Heater

Despite the fact that it’s a tankless job, someone has to do it. Leaving aside the dad jokes, installing a tankless water heater is a serious undertaking that should be approached with caution. Our goal is to make this process as simple and pleasant as possible, so we’ve included step-by-step instructions for both gas and electric units below. Take note that replacing a tankless water heater is a time-consuming process requiring advanced technical knowledge. So, if you aren’t confident in your plumbing and electrical abilities, it is preferable to engage a licensed professional – in certain areas, this is a legal requirement.

How to Install a Gas Tankless Water Heater

Installation and replacement of tankless water heaters may be quite expensive, as we realize. Installing your own unit is doable, but we recommend that you proceed with caution. This should only be attempted if you have extensive experience working with gas lines, water lines, and electrical systems. Installing your tankless water heater incorrectly might result in significant harm to your home. Unsafe gas line installation may cause explosions, while faulty gas venting can result in deadly carbon dioxide leaking into your house.

If you are considering a do-it-yourself installation, it is critical that you understand the terms of your insurance policy.

You can install your unit yourself if you are confident in your abilities and have double-checked with your insurance company. The instructions below will guide you through the process.

Step 1

Depending on the manufacturer, if their systems are not installed by certified professionals, the warranty may be voided.

Step 2

Make certain that you obtain all necessary state or local permissions before installing or upgrading a water heater.

Step 3

For water pressure more than 80 psi, you’ll need to install a pressure-reducing valve upstream of the new water heater before it will work properly. When establishing the cold and hot water connections (as described in the section below under “Establish the cold and hot water connections”), you should consider whether or not you need to install one.

Step 4

  • Make sure you check your local construction codes to see where you may put your water heater in your home. These tankless gas systems must be vented directly to the outdoors, rather than through a chimney, in order to function properly. Consequently, it is vital to identify a position where the unit may readily vent outdoors while also complying with local code requirements for vent placement. Carefully review the manufacturer’s installation instructions to ensure that you have adequate clearance around the device
  • Stay away from locations where:
  • To find out where you may put your water heater in your home, check with the building code in your area. Tankless gas units must be vented directly to the outside through a pipe, rather than through a chimney, in order to function properly. Because of this, it is essential to identify a site where the unit can quickly vent to the outside while also complying with local code requirements for vent placement. To ensure that you have appropriate clearance around the device, carefully read the manufacturer’s installation instructions. Stay away from locations that include the following characteristics:

Step 5

Make careful to accurately measure the space where you intend to install the water heater to ensure that you acquire the appropriate-sized unit.

Step 6

  • Tankless gas water heaters consume more gas than traditional tank-style water heaters. Determine whether or not your present gas line will be sufficient initially
  • If not, upgrade it. A professional contractor will be required to install a newer, larger gas pipe if your present gas line is unable to keep up with the demand.

Step 7

  • If there isn’t a shut-off valve before the heater, cut off the main water supply
  • Otherwise, turn off the heater. Remove the heater from service by closing all power and gas supply valves to it. Disconnect the unit’s power
  • When dealing with hot water, utilize a hose that is designed to tolerate high temperatures. To relieve pressure in the system, open a hot water faucet for a few minutes. Allow it to completely drain
  • Ensure that the water heater is disconnected from the gas and water pipes. Make sure to properly dispose of your old water heater.
  • The water heater should be disconnected both from the gas and water supply pipes. It’s important that you properly dispose of your old water heater

Step 8

  • Ensure that the device is properly supported by constructing a mounting box that is approximately four inches away from the wall. The foundation wall should be properly secured with appropriate anchors. Follow the manufacturer’s instructions for mounting the device to the box firmly.

Step 9

  • Hiring a professional contractor should be your first choice unless you have extensive knowledge with gas line installations. Utilize a threaded black iron pipe to connect the existing tee to the unit position if your present gas line is the suitable size and you can connect it without breaking the existing connection. Remember to switch off the main gas line before removing the down pipe from the previous unit if you’re replacing it. After ensuring that the gas line is routed to the right location, you should install a tee, a sediment trap, and a gas shut-off valve. The shutdown valve and sediment trap should be connected to the heater in accordance with the manufacturer’s instructions. Install a new gas supply line from the tee to a location where it can be conveniently connected to the gas line of the new unit. You may utilize a black pipe or a flexible gas supply line to accomplish this task. Assemble the connections in the direction of the heater, starting with the tee, using two wrenches. Whenever possible, use thread sealant developed for gas lines when connecting gas pipe assemblies. After you have completed all of the gas line connections, you should test the line. Before turning on the gas, check the pressure with a pressure gauge.

Step 10

  • Connecting the water heater valves to the water supply line should be done according to the manufacturer’s instructions.
  • Connecting new hot and cold water lines to existing water lines should be done with copper pipe. Continue to connect the wires to the new unit. It is possible that copper pipe will need to be cut and soldered to the unit.
  • Depending on whether your water system includes an anti-siphon valve or a check valve on the supply line, you may require an expansion tank close to the cold intake. More information can be found in your vehicle’s owner handbook. Bell hangers should be used to secure the pipe to the wall. Place the pressure relief valve in its proper location. Installing a purge valve and a pressure relief valve should be done according to the manufacturer’s instructions.

Step 11

  • Make sure there are no leaks by turning on the water supply. To check for leaks, turn on the gas and wait a few minutes. It is possible that you will need to bleed the line. Afterwards, switch off the gas supply until the installation is complete.

Step 12

  • When it comes to correctly venting the device, follow the manufacturer’s recommendations as a reference. There’s a considerable probability that you’ll be able to vent your water heater straight through the rim joists in your home. Only utilize pipes that have been specifically designed for this sort of venting. In some cases, depending on the manufacturer, you may require a vent kit. Make sure that the vent shaft of the new unit is sealed with a heat-resistant silicone sealant. Afterwards, attach a connection to it and secure it with an appropriate hose clamp
  • Place a length of stainless steel vent pipe on top of the structure. Put on a retaining ring to keep it in place. Folding over the tabs can help to keep it secure. Slip an elbow inside a pocket. Make sure that the aperture faces the direction in which the unit will vent to the outside
  • Select a spot on the joist or wall that will serve as the center of the vent hole for the purpose of venting outdoors. Drill a hole from the inside of the building at the location you’ve picked. Make a circle on the outer wall with a vent thimble and tape it in place. A spade bit should be used to bore a 1-inch hole at the center of the circular. Remove siding and shingles from around the vent hole in order to allow the flange thimble to be flat against the outside wall
  • Caulk around the edge of the flange with silicone caulk to seal the edge of the flange to the outside wall. Then, place the flange into the vent hole that has been created. Use screws to securely fasten it to the outer wall and silicone to seal the screws in place. Installing the internal flange should be done from the inside. A portion of vent pipe should be routed through the flange aperture. Tabs should be used to secure each part. Attach a short portion of vent pipe to the outside of the house and then connect the vent hood
  • Put the shingles and siding back on the house that you removed previously.

Step 13

  • To remove air from the water pipes and heater, turn on the faucet to its full “hot” setting. Close the water supply valve

Step 14

Connect the water heater to the wall outlet. That is all there is to it.

Step 15

The hot water line that originates from the water heater should be insulated.

Step 16

The gas should be turned on when the installation is complete. Your water heater should be up and running at this point!

How to Install an Electric Tankless Water Heater

The gas should be turned on after the installation is complete. Your water heater should be up and running at this time.

Step 1

Depending on the manufacturer, if their systems are not installed by certified professionals, the warranty may be voided.

Step 2

Confirm that your electrical service panel has the capacity to manage the energy demands of an electric tankless water heater before installing one. It’s possible that you’ll need to upgrade your panel or install a whole new one. It is possible to uncover useful information by inspecting your electrical breaker box or the label on the electrical panel in your home. You might also consult with an electrician. The majority of suitable water heaters require a minimum of four 40AMP breakers to deliver hot water for a two and a half bath house.

Step 3

Examine your electrical service panel to see if it is capable of handling the increased energy demands of an electric tankless water heater. Your panel may require an upgrade or you may need to install a whole new one. You can look at the electrical breaker box or the label on your electrical panel to locate pertinent information. Alternatively, an electrician might be contacted for assistance. The majority of suitable water heaters require a minimum of four 40AMP breakers to deliver hot water for a two and a half bath residence.

Step 4

Make certain that you obtain all necessary state or local permissions before installing or upgrading a water heater.

Step 5

  • In order to heat water for the entire house, it is best to locate the unit closest to the area in which the majority of the hot water is consumed. If you’re installing a point-of-use system, try to locate them as near to the points of use as feasible. Always keep in mind that most electric tankless water heaters must be mounted vertically, with the water and electrical supply connections on the bottom of the unit. Follow the manufacturer’s recommendations for leaving a particular amount of clearance for service
  • In general, you want to stay away from locations where:
  • Temperatures below freezing might have an impact on the unit. Any form of liquid might be sprayed on the device on a regular basis. There is a significant amount of humidity and wetness

Step 6

It is possible that the unit will be damaged by freezing temperatures: Regular splashes of any form of liquid might damage the device. Humidity and moisture levels are quite high.

Step 7

You don’t want your office to become a swamp!

Step 8

  • Your desk should not be overrun with items.
  • When dealing with hot water, utilize a hose that is designed to tolerate high temperatures. To relieve pressure in the system, open a hot water faucet for a few minutes. Allow it to completely drain
  • Ensure that the water heater is disconnected from the gas and water pipes. Make sure to properly dispose of your old water heater.
  • For information on how to properly dispose of it, contact your local recycling and/or sanitation agencies.

Step 9

  • Remove any screws that are holding the front cover of the new device in place
  • And Please keep in mind that you may need to remove at least one plug before you can set it aside.

Step 10

A set of adequate anchors and screws should be included in the box.

Step 11

  • Connections for the cold and hot water should be made. The right side of the body is commonly affected by a cold.
  • The quickest and most straightforward method is to use stainless steel flex pipe with Teflon tape. You can also utilize copper tubing that has been rated for use in high-temperature environments. If you have to cut into a pipe, make sure the edges are clean. Before connecting the pipes to the water heater, flush them with water once they have been soldered. Also keep in mind that too much heat might cause harm to the water heater. If you want to do maintenance on your heater, it’s a good idea to install a shut-off valve before and after it. This will allow you to stop off the water supply to the unit without shutting off the water supply to the rest of your home
  • If you need to install a pressure reduction valve, you should do it immediately on the cold water side of the plumbing system. The installation of a temperature and pressure relief valve is unlikely to be necessary (T P). However, you should double-check your local and state installation rules to see whether or not you require a permit.

Step 12

  • In this case, stainless steel flex pipe with Teflon tape is the quickest and most straightforward solution. It’s also possible to utilize copper tubing that has been rated for high-temperature usage. Make sure to tidy up the edges of the pipe if you have to cut into one. Prior to attaching the water heater to the soldered pipes, clean them out with water. It’s also important to realize that too much heat might be detrimental to your water heater. If you want to do maintenance on your heater, it’s a good idea to install a shut-off valve before and after it. This will allow you to switch off the water supply to the unit without also turning off the water supply to the rest of your home
  • If you need to install a pressure reduction valve, you should do it now on the cold water side of the plumbing system
  • Temperature and pressure relief valves are not likely to be required in your situation (T P). It’s best to double-check your local and state installation codes, though, to make sure you don’t require one.

Step 13

This step must not be skipped!

Step 14

  • Heater on one side, and electrical panel on the other, is the recommended arrangement
  • Comply with the manufacturer’s wiring diagram and their instructions for selecting the appropriate wire, circuit breaker number, and circuit breaker size
  • And Cutting and stripping every wire set to the proper length is followed by pushing them through the bottom holes of the new water heater’s housing. After that, connect the wires to the appropriate slots on the terminal block.
  • For the most appropriate torque, see the product handbook. It is important to remember that a ground conductor must be connected to the circuit breaker panel and the grounding busbar of the unit for each circuit.
  • Double-check that all of the electrical connections are in proper working order and that all of the wire sets have been appropriately installed.

Step 15

Make use of the screws that you already removed.

Step 16

The device should be turned on at this point. Select your chosen unit settings from the drop-down menu.

Step 17

If you plan to install a tankless electric water heater yourself, it’s critical that you understand what you’re getting yourself into before you begin. This Might Also Be of Interest to You: Installing or replacing a gas water heater is a simple process.

If you arrive at a job site without the proper tools or a clear grasp of the tasks at hand, it’s likely that you’ll run into problems that will cost you both time and money.

1. Switch Off Circuit Breaker and Water Supply

Immediately before to beginning the job, it is critical that the circuit breaker be turned off in order to guarantee that the electric wires are not powered on while you are working. At this time, you should also switch off the water supply to your home unless you want to risk flooding your home while attempting to replace your present water heater with a new one. Always keep in mind that flooding may cost tens of thousands of dollars in damage, which is why doing the first item on this list is the most critical.

2. Drain Your Old Heater Before Disconnecting It

It is critical that you turn off the circuit breaker before you begin working on the project to guarantee that the electric wires are not energized while you are doing your task. At this time, you should also switch off the water supply to your home unless you want to risk flooding your home while attempting to replace your existing water heater with a new one. Keep in mind that flooding may result in thousands of dollars in damage, which is why the first item on this list is the most crucial of the whole list.

3. Remove the Front Cover

The front cover of the new tankless unit should be carefully removed with a screwdriver before the unit can be installed. Once all of the screws have been removed, store them in a safe location where they will not be misplaced. It is vital to use all of these screws in order for your water heater to perform correctly. Take into consideration the possibility that wires will be connected between the cover and the device. Carefully unplug the cables before removing the lid completely.

4. Mount the Water Heater

Following that, the device will need to be attached to a wall. Make certain that the water heater is not installed in a cluttered or disorganized location of your house or business. Having said that, it’s critical that you have quick access to the unit in the case of an accident or other emergency.

Mounting the water heater is straightforward and may be accomplished using a combination of screws and the mount that comes with the unit. Follow the installation instructions that came with your item.

5. Connect Any Pipes

Upon completion of the installation, you will need to connect the pipes that will deliver hot water throughout your home. These are the connectors that will be used to bring water into and out of your water heater. They should be positioned at the bottom of the unit, if possible. When you receive your device, it is possible that you may be given an installation diagram, which you should look to in order to establish where the connections should be made. Stainless steel is the ideal sort of pipe material for a tankless water heater since it is corrosion resistant.

Copper and PVC piping are suitable alternatives to stainless steel piping if you do not have access to stainless steel pipes.

Many instruction manuals recommend that you clean your equipment on a regular basis.

  • Upon completion of the installation, you will need to connect the pipes that will deliver hot water throughout your home to the device. It will be necessary to connect these connections in order for your water heater to function correctly. Ideally, they should be near the bottom of the storage unit. Perhaps your equipment came with an installation diagram that you can use to figure out where the connections should be made. If so, keep that diagram handy for future reference. When it comes to tankless water heaters, stainless steel is the best sort of pipe material to use. When exposed to extreme temperatures, it does not impair the system’s accessibility or adaptability. You can use copper or PVC piping as an acceptable substitute if you do not have access to stainless-steel pipes. Choose a flexible pipe made of stainless steel so that you can be certain that the connections can be simply disconnected, which is beneficial if you intend to clean them on a regular basis. Routine cleaning is encouraged by many instruction manuals. Articles that are related:

6. Install Flow and Pressure Valves

As soon as all of the connections have been completed, it’s time to install the flow and pressure control valves. Flow valves are straightforward to install. In the event that repairs are required, you may simply cut off the water supply to the heater rather than having to shut off water throughout the rest of your property. Pressure valves are only required if and when the local plumbing authority specifies that they are needed. The pressure release valve should be put on the side of the electric water heater that is closest to the “hot water.” To ensure optimum safety, you might also install one on the other side of the heater from the heater.

7. Bleed the Hot Water System

When you get to this step of the installation procedure, you should have the water heater connected and completely installed. However, you’ll still want to go through the process of bleeding the system before turning on the hot water supply. Every hot water outlet in your home should be opened, as this will aid in the removal of any air that may have accumulated in the system. Ensure that these outlets remain open for a few minutes, following which the bleeding procedure should be finished successfully.

8. Inspect Electrical Connections Before Attaching Cover

The water heater should be connected and completely installed at this point in the installation procedure. The bleeding process, on the other hand, should be completed before turning on the hot water supply. If possible, open every hot water outlet in your home to allow any trapped air to escape from the system. Ensure that these outlets remain open for a few minutes, following which the bleeding process should be finished.

9. Switch Circuit Breaker On

It is safe to turn on the circuit breaker now that you are no longer need to perform any maintenance on the heater directly.

10. Check Temperature and Test Outlets

Once the water heater has been switched on, you’ll want to adjust the temperature settings on the system. Because these units may get extremely hot when used at their maximum settings, it is suggested that you avoid using them in order to reduce the possibility of burns. This is also a good time to check every hot water outlet in your home, including taps, showers, dishwashers, and laundry washers, to ensure that the temperature is proper and that the water warms up quickly.

Turning down the temperature settings may be necessary if the water is becoming too hot to handle.

DIY Tankless Water Heater Installation Is Dangerous

However, just because there are safety procedures in place to prevent hot water tanks from exploding does not imply that they are impenetrable to failure. When unlicensed individuals install hot water tanks, the possibility of something like this occurring increases, and the likelihood that they will not have the necessary insurance to pay the damage if it does occur increases. Water heaters, in particular, those run on gas are extremely combustible. An explosion or a fire might occur if one of the installation’s components is mishandled.

Carbon Monoxide Leaks

They are undetectable by the human senses, which is why they are referred to as a silent killer. A competent plumber can help you avoid carbon monoxide poisoning by ensuring that your system is properly vented before the problem occurs. Nonetheless, a CO detector should always be installed. This procedure is crucial for in-home safety, but it is frequently performed incorrectly by inexperienced repairmen. Whatever number of ancient systems your uncle installed years ago, please do not make the fatal error of attempting to install your own water tank on your own dime.

In many cases, amateur installation is not covered by your guarantee.

The majority of internet sales and purchases are canceled right away.

Without proper installation, the hot water heater may be damaged or even destroyed, and why should the manufacturer be responsible for such a thing?

DIY Can Hurt Your Property Value

Sure, you might be able to do a plumbing task on your own and save some money, but is your handy work up to code? Did you get a permit to do this? When it comes time to sell your property, such blunders might end up costing you a lot of money in the long run.

How Tankless Water Heaters Work

Known variously as demand type, on-demand, or instantaneous water heaters, these appliances heat water directly, eliminating the need to store water. A flow detecting device is installed in a tankless heater, and it is triggered anytime the hot water tap is opened. A gas burner or an electric element is used to heat the water, which is then sent to the various locations in your home where it is needed.

You won’t have to worry about running out of hot water because there isn’t a tank that has to be filled. When you turn off the hot water faucet, the machine detects that the flow of water has ceased and automatically turns off the heating element.

Advantages Of Tankless Water Heaters

  • They are more compact than typical storage heaters, are wall-mounted, and do not take up any floor space when not in use. As a result of their size, they can be particularly appealing in houses where space is limited
  • They can also help you save money on your energy bills. According to the United States Department of Energy, heating water accounts for around 30% of a family’s total energy use. It is possible to save up to 50% on these expenditures by installing a tankless water heater, resulting in an average yearly savings of $80. Tankless water heaters are also more durable and less likely to malfunction, resulting in potentially disastrous flooding in your house. Compared to traditional water heaters, tankless systems have a lifespan that is about twice as long – 20 years or more.

Disadvantages Of Tankless Water Heaters

  • Tankless units are more costly than conventional units. It will cost around the same as a standard tank type to purchase an electric tankless heater, however a gas tankless heater would cost between $1,000 to $1,200. The national average for tankless unit installation is somewhat more than $1,700, which is in addition to the original cost of the unit. A safe vent must be created for a gas unit to prevent carbon monoxide from collecting within the property in many circumstances. Existing plumbing must also be expanded or moved in many cases. Tankless water heaters do not provide “instant hot water,” even when energy savings are taken into consideration
  • For many households, it will take around 20 years to completely return their expenditures. It is not always the case that a tankless water heater delivers hot water to your faucet any faster than a traditional water heater, contrary to common belief. In fact, a tankless device may be more time consuming. It takes some time for the tankless unit’s heating element to warm up the water before it can be delivered to the faucet
  • The amount of hot water that can be delivered is limited by the unit’s ability to heat the water. It is typical for tankless water heaters to provide 2-5 gallon-per-minute flows of hot water, which may not be sufficient for several simultaneous uses of hot water in your home. For example, having a shower and running the dishwasher at the same time may cause a tankless water heater to reach its maximum capacity and fail. Comparing tankless versions, especially if you live in a multi-person home, is important. Pay close attention to the gallons per minute (GPM) flow rate of each type. The bigger the number of users and the greater the number of simultaneous usage options, the higher the GPM requirement. In order to satisfy the needs of a big home, one alternative is to install many tankless units
  • However, this can become quite costly over time. It is possible that tankless water heaters will not provide hot water during a power outage. Tankless water heaters, in contrast to traditional water heaters, do not provide a backup hot water supply in emergency scenarios
  • Tankless systems are also subject to failure owing to hard water. Hard water is a concern for all water heaters, but it is particularly challenging for tankless water heaters. They should be completely emptied and their filters updated on a monthly basis. They also require frequent flushing to function properly. (Tank units only need to be flushed once or twice a year, at most.) If you don’t take the necessary precautions, hard water can completely ruin a tankless water heater in as little as two years. In addition, failing to adhere to these maintenance requirements may result in the voiding of the manufacturer’s guarantee
  • Tankless devices are hard to maintain. Investigate the interior workings of a common tankless water heater or air conditioner. As a result of all the complex technologies tankless water heaters rely on, it is easy to understand how much may possibly go wrong.

Gas or Electric

Electric tankless water heaters are significantly less expensive than their gas counterparts. Installation is less complicated and less expensive, and they are often less difficult to maintain than gas-powered ones. Only a few handful, however, have the capability of serving many locations at the same time. Gas units are available in a wide range of types and sizes for both residential and commercial applications, with outputs ranging from 130,000 to 380,000 BTUs in certain cases. More BTUs equate to more heating capacity.

  • As a result, your home’s gas pipe, meter, and main line to the meter may not be correctly proportioned, necessitating a costly reconfiguration and installation of new equipment.
  • The total energy efficiency of a tankless water heater is assessed using an energy factor (EF) rating, which is available for both gas and electric types.
  • Tankless water heater energy factors now range between.64 and.91 for gas-fired devices, and up to.99 for electric versions, depending on the manufacturer.
  • For a home of one or two persons, a tankless electric unit will most likely be more than sufficient.

Water Heater Protection

Whatever method you use to fulfill your household’s hot water requirements, you’ll want to make sure that the investment you’ve made in your water heater is protected. That entails completing the preventative water heater maintenance advised by the manufacturer, as well as routinely emptying the tank (or lines) to remove potentially harmful silt and scale. Consider obtaining an American Home Shield® Water Heater Home Warranty to help reduce the expenses involved with the repair and replacement of your water heater even more.

Installing a Tankless Water Heater

“On-demand” is in high demand these days, whether it’s for movies or information, or for food or amusement. It has even made its way into the field of plumbing, where tankless water heaters have grown increasingly popular since they can provide hot water whenever it is required.

Learn about the advantages and disadvantages of tankless water heaters, as well as the installation concerns that come with these contemporary money-savers, before making your decision.

What Are The Pros and Cons?

Tankless water heaters, as opposed to standard water heaters, which heat water in a storage tank, give hot water “on demand,” or just when it is required. The fact that they heat water directly rather than through a tank means that they do not suffer from the same standby energy losses that are associated with storage water heaters. The hot water tap is triggered by turning on the cold water supply, which goes through a pipe into the tankless unit, where it is heated by either a gas or electric element.

Tankless water heaters, while initially more expensive than regular systems, may save a significant amount of money over the long run.

In addition to having high upfront expenditures, smaller tankless systems may not be able to provide enough hot water to all of the appliances and showers at the same time.

In addition to providing on-demand hot water and lowering long-term energy expenses, tankless water heaters conserve space and have longer warranties, which are important considerations for many homeowners.

Installation

While it is feasible to install a tankless water heater on your own, it is not a project that should be attempted by unskilled do-it-yourselfers. Tankless water heaters are available in a variety of sizes and designs, including propane, natural gas, and electric versions, as well as single-room and whole-house variants. They are also available in a variety of fuel types. Due to the fact that a typical tankless heater consumes more gas than the largest home furnaces, you will need to consult with your local gas provider to ensure that your gas main is properly sized.

  • Aside from that, you’ll also have to pay for someone to properly dispose of the old tank.
  • The new water heater may also require wiring, depending on whether you’re fortunate enough to have a power supply of appropriate size nearby.
  • It is possible that you may need to modify your gas lines in order to meet higher usage.
  • The next step is to ensure that the entire installation complies with building standards and that your homeowner’s insurance will cover any damage caused by any faults.
  • When you purchase your unit from a dealer, most of them will give installation at a subsidized fee.

Tankless Water Heater Installation

A tankless hot water heater differs from a standard gas water heater in that it only heats water when it is required; there is no tank, and therefore no energy is spent heating water that is not required. A tankless water heater in your Maryland house will provide you with hot water on demand, which means you will never run out of hot water in your home again. Furthermore, because the compact device is attached on your wall, it frees up the area that would otherwise be taken up by a standard water heater.

EfficiencySavings of Tankless Water Heaters

In addition to being one of the most energy-efficient water heaters available, a gas tankless water heater utilizes just the energy required to heat the water when it is needed. This product is an excellent energy-efficient solution for your house, especially in light of rising energy expenses and increased environmental consciousness among the general public. There are several advantages to purchasing a gas tankless water heater, including the following:

  • Water heaters that use less energy
  • Water that is always hot
  • Tankless systems are simple to operate and have a longer life expectancy (the typical tankless system lasts 20 years). There is no tank to leak
  • It conserves space
  • Temperature control that is precise
  • System that can diagnose itself

What Size Tankless Water Heater Do You Need?

Tankless water heaters operate in a different manner than typical water heaters, according to the majority of experienced plumbers. Despite the fact that they are available in a variety of sizes, the size of tankless water heaters is determined by the number of gallons of hot water they can supply every minute rather than the number of total gallons of water they can hold. Heaters that use the traditional method heat and store hot water in a tank until it is needed. Tankless water heaters only heat water when it is actually required to do so.

Alpine Plumbing 202021-05-07T19:33:49+00:00 Tankless Water Heater Installationalpineplumb202021-05-07T19:33:49+00:00 Isn’t it frustrating when you go to take a shower and discover that you’ve run out of hot water? Seeing those hefty energy bills arrive in the mail each month is even more frustrating. Fortunately, Alpine Plumbing offers a solution for your problem: the tankless water heater! Energy expenses increase when you heat water in your house when it is not required. Even when you’re not using the water, traditional tank-style water heaters continue to utilize gas to keep the full tank of water hot by continuously heating it.

How It Works

When you use a tankless heater, water only enters the heater when hot water is required in another part of your home. Because the water is heated as it travels through the heater, you will always have hot water as long as you have access to water. It takes an average storage tank water heater roughly ten years to reach the end of its life expectancy. Tankless systems have a longer lifespan than traditional systems because they do not collect water, which reduces the danger of corrosion to practically zero, allowing them to last nearly twice as long as the regular model.

And, even better, you only heat the water that you really use! Allow the professionals at Alpine Plumbing to save you money and headaches by installing a tankless water heater in your home or business now.

Safety Modifications

When it comes to installing a tankless water heater, there are a few safety precautions that must be taken. We will not be able to use your current water heater flue for this project. The reason for this is that high-efficiency tankless water heaters emit exhaust that causes condensation, thus we must install two PVC pipes. Typically, one pipe is used for intake air, while the other is utilized for exhaust air, which is vented out the side of your property. Alpine Plumbing has built a reputation unrivaled in the Milwaukee region over the course of nearly four decades in the business.
