Tankless Water Heater How To Install

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.

  1. Request that the gas provider inspect your new unit to ensure that it is receiving the appropriate amount of manifold pressure for it.
  2. It is better to employ a professional plumber to install a new gas line if you need to replace an existing one.
  3. This will save you time and money.
  4. 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.
  5. A damper is an excellent addition for those who live in colder climates since it prevents chilly air from re-entering the home.
  6. Floor drains and utility sinks should be used to dispose of the excess liquid.
  7. In addition to gas, a gas unit requires 120-volt electrical power.
  8. 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.
  9. 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.
  10. 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

In the majority of circumstances, a new tankless water heater will be installed in lieu of an existing storage water heater. In Ron Hazelton’s video above, he refers to our website for the directions, which are as follows: How to Flush or Drain a Water Heater (with Pictures). In order to remove the old water heater, turn off the valves on the two water lines (one for the input and one for the output) that lead into the existing water heater and disconnect them. To remove and detach the water heater’s lines from the water heater, use channel-type pliers or a pipe wrench.

  • Drain the tank by opening the drain valve located at the bottom.
  • Don Vandervort writes for HomeTips.
  • A segment or two of vent pipe should be disconnected and removed.
  • If you decide to handle it yourself, cut off the circuit at the service panel and check to be that the power has been turned off completely.
  • If you require assistance with this project, contact a local water heater professional.

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.

Finally, test the equipment to ensure that it is in proper functioning condition. Resource Highlighted: Find a Pre-Screened Water Heater Pro in Your AreaCall today for free estimates from pre-screened water heater professionals in your area: 1-866-342-3263

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.

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:
  • 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 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

  • When compared to traditional tank-style water heaters, tankless gas water heaters consume more gas. Decide whether or not your present gas line will suffice before proceeding. It may be necessary to have a professional contractor install a newer, larger gas line if your present gas line is inadequate.
  • 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 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

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 water lines and electrical systems. Installing your tankless water heater incorrectly might result in significant harm to your home. 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

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

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 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

Disconnect any circuit breakers that are connected to the new device. This is critically crucial!

Step 7

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

Step 8

  • 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.
  • 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 cold and hot water connections should be made first. On the right side of the body, cold frequently occurs.

Step 12

  • By opening various hot water outlets, you may remove any trapped air from the device and the pipes. While you’re waiting, you should inspect each and every connection for leaks.

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

Start by turning on the hot side of a faucet in your home. After the water temperature has steadied, take another reading. The temperature may be adjusted on the device itself if you desire to do so.

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

A tankless hot water heater differs from a standard gas water heater in that it only heats water when it is needed; there is no tank, and therefore no energy is spent heating water that isn’t being utilized. With a tankless water heater in your Maryland house, you will have hot water on demand, which means you will never run out of hot water in your residence.

As an added bonus, you may mount the compact water heater to your wall, therefore reclaiming the area that would otherwise be taken up by a regular water heater.

  • 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.

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.

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

  • They are more compact than typical storage heaters, are wall-mounted, and do not take up any floor space when in operation. When it comes to homes where square footage is limited, their size may make them particularly appealing
  • They can also assist you in lowering your energy expenditures. Energy expenses for heating water account for around 30% of a family’s total energy bills, according to the United States Department of Energy. It is possible to save up to 50% on these expenditures by installing a tankless water heater, resulting in an annual savings of around $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 water heaters have a lifespan that is about twice as long – 20 years or longer.

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

Tankless water heaters are becoming increasingly common, and tankless water heaters account for the majority of the water heaters I evaluate these days. Tankless water heaters take up less area and may be put both indoors and outdoors, saving you money on energy costs. This blog will have all of the necessary information on the plumbing code requirements for the installation of tankless water heaters.

Does replacing the Tankless water require a plumbing permit?

For the installation of a new tankless electric water heater as well as a new gas water heater, local governments (cities and counties) require a plumbing permit. After all of the repair has been finished, the local authorities will need a final examination of the water heater to ensure that everything is in working order. (See CPC 503.0.) The water heater may need to be relocated if a new gas line is being installed. In addition to the final inspection, an extra gas test inspection will be necessary.

Who can apply for a plumbing permit?

Plumbing Contractor as defined by the California State License Board (CSLBa C-36). When a homeowner performs the plumbing repair himself or herself, however, the local governments will enable him or her to get the necessary plumbing permits.

Tankless water heater Location

The tankless water heater’s position in accordance with the plumbing code is not specified. It is specified by the manufacturer of the water heater whether the water heater is acceptable for installation inside or outside; thus, I recommend reviewing the manufacturer specifications before purchase if you have a certain site in mind. However, the majority of tankless water heaters are authorized for both indoor and outdoor use. If you intend to transfer the water heater to an exterior position, you must first obtain permission from the local planning authority.

  1. A room that is used for sleeping or is intended to be used for sleeping purposes
  2. A toilet
  3. A sink
  4. A cupboard for garments
  5. Inside of a closet or other small enclosed area that leads into a bathroom or bedroom. Water heaters that are vented directly are an exception. (505.1) (CPC 505.1)

Continue reading:Why does my water heater produce noises and how can I stop it.

Tankless water heater clearance

Another problem that the plumbing code does not specify is the tankless water heater clearance, and it is up to each manufacturer to determine the appropriate distance between the tankless water heater and combustible and non-combustible materials.

Temperature and Pressure (TP) Relief ValveDischarge Line Water

A minimum of a 34 inch T P drain must terminate “outside” of the structure, no closer than 6 inches or farther than 24 inches from the ground surface. The T P line must be oriented downward, with no threads at the end of the line. Water heaters situated in the garage may terminate on the garage floor, provided they meet the same distance criteria as the water heaters located elsewhere. (CPC- UPC 505.6 CPC505.4, 508.5608.5; CPC- UPC 505.6 CPC505.4, 508.5608.5) T P does not drain into a water heater’s drain pan, as it should.

Gas line sediment trap (drip leg)

Installed on the gas supply to the water heater is a sediment trap (T, 3″ minimum nipple and cap).

Tankless Water Heater Installation

You dread it when you try to take a shower and you realize you’ve run out of hot water.alpineplumb202021-05-07T19:33:49+00:00Doesn’t everyone despise it when they 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.

Now that you’ve chosen your tankless water heater, it’s time to get it installed in your house or place of business. Installation and maintenance of your water heater can help you get the most out of it in terms of energy efficiency. A variety of elements influence the success of an installation. These considerations include the type of fuel used, the environment, the needs of local construction codes, and safety concerns, particularly with regard to the combustion of gas-fired water heaters.

4 Factors to Consider When Hiring a Contractor For Installation

  1. Request written cost estimates, as well as contact information for references. Check with your local Better Business Bureau to see whether the firm is legitimate. Examine if the firm will seek a local permit if one is required and whether it is familiar with local construction rules, among other things.

If you’re determined to install your water heater yourself, first speak with the manufacturer about the best way to proceed. The relevant installation and instruction manuals are normally available from the manufacturer. Contact your municipality for information on acquiring a permit (if one is required) and on water heater installation codes in your area. The majority of tankless water heaters have a life expectancy of more than 20 years, which is excellent. They also contain easily changeable parts, which allows them to last for many more years than conventional models.

Storage water heaters, on the other hand, have a lifespan of 10–15 years. Periodic water heater maintenance may considerably increase the life of your water heater while also reducing the amount of energy it consumes. Seek advice from your owner’s handbook on particular maintenance requirements.

  1. Indoor gas installation, electric installation, and outdoor gas installation are all available options.

The following services are available: Indoor Gas Installation, Electric Installation, and Outdoor Gas Installation

Indoor Gas Installation

Before installing any gas tankless water heater, we always recommend that you contact with a professional installer or a gas provider, as well as the installation instructions for that particular model. Every Bosch tankless water heater that we sell comes with an installation manual, including the following models: When installing a gas tankless water heater, there are a number of key factors to take into consideration:

A. Do I have the correct gas connection coming into my house and do I have enough gas power to run the tankless water heater I purchase?

Before installing any gas tankless water heater, we always recommend that you contact with a professional installer or a gas provider, as well as the installation instructions for the specific model. Every Bosch tankless water heater that we sell comes with an installation manual. When installing a gas tankless water heater, there are a number of critical factors to consider:

B. Do I have proper ventilation?

Each and every gas tankless water heater is required to exhaust the surplus warm air that they generate. They can either vent vertically up through a chimney or roof pitch, or horizontally through a side wall, depending on their configuration. Some units can only vent horizontally, while others can only vent vertically, while yet others can vent in either direction. Before making a choice on which gas tankless water heater may be the best fit for your needs, you should learn about your venting alternatives.

Components You Need to Consider

When constructing a gas or liquid propane tankless water heater, there are various components to take into consideration:

1. Vent Adapter and Stainless Steel exhaust hose

An adapter for attaching the tankless water heater to the exhaust line is necessary in this situation. If you choose a 3 inch adapter, you will need to choose between a 3 inch and a 4 inch adapter, depending on the model. Because of the heat generated during the venting process, UL certified Stainless Steel vent pipes must be used for any gas or liquid propane tankless water heater venting. It is not suggested to use standard PVC plumbing.

2. Vertical vs. Horizontal Installation

Tankless water heaters that run on natural gas or liquid propane can be positioned either vertically or horizontally. Some models can only be fitted in a specific method, therefore please study the product information published on our website regarding the product to have a better idea of how it may be mounted.

Horizontal Installation:

Tankless water heaters powered by natural gas or liquid propane can be mounted vertically or horizontally. Some models can only be installed in a specific method, therefore please study the product information published on our website regarding the product to have a better knowledge of how it can be installed.

Vertical Gas Installation:

In comparison to horizontal installation, vertical installation of gas tankless water heaters might introduce additional variables into the system. The components required for the installation, on the other hand, will stay essentially unchanged. The following items are required: a vent adapter, at least one 90 degree elbow, and a condensate trap (the condensate trap is only necessary for Rheem gas units). Bosch units are equipped with a built-in condensate trap. You’ll need to purchase enough stainless steel venting pipe to allow the exhaust to reach the outside of your property.

It is necessary to install a firestop in each ceiling through which the unit is ventilated. Finally, you’ll need roof flashing, a storm collar, and either a 90-degree elbow or a rain cap to finish the job off properly.

Combustion Air:

Tankless water heaters require combustion air to function properly. It’s critical to understand how combustion air will be transported to your water heater, as well as how much combustion air will be required in your water heater. When used in an unconfined environment, combustion air might be as simple as the air that circulates around your home. Some of the tankless units we sell are designed to operate in this sort of environment since they do not require fresh air to be drawn into the space where they are installed from outside.

Constrained spaces (such as a closet) may need the installation of air ducts or the addition of extra air inlets.

This pipe draws fresh air from outside your home into the area where the tankless water heater will be put.

Electric Tankless Water Heater Installation

An electric tankless water heater is preferred by many individuals who do not have the power requirements for a gas tankless water heater or who are unable to vent a gas tankless water heater due to the fact that they do not require any form of ventilation. In contrast to this, electric versions require a significant amount of electricity to operate. It is recommended that you read the owner’s handbook before installing an electric tankless water heater. You can also click here to get a comparison table of all of the units we sell.

The necessary amps will range between 150 and 200 amps, depending on which electric tankless water heater best suits your home’s requirements.

A number of homeowners have chosen to add an additional breaker box to their current wiring, while others have chosen to replace their existing breaker boxes with larger models.

Outdoor Model Installation

If you are unable to properly vent a typical gas water heater, outdoor tankless water heaters may be a suitable option for you to consider. If you are interested in installing an outdoor model, you will need to check the owner’s handbook to determine what sort of clearances are necessary for the outside installation.
