How To Install Instant Hot Water Heater

How to Install an Instant Hot Water Heater

The most common types of house water heaters are the massive storage models that take up a substantial amount of space in the garage or basement. Some households are opting to install instantaneous, or tankless, hot water heaters as a more energy efficient option. These extraordinarily compact devices heat water on demand, eliminating the need for people to wait for hot water to reach a specific tap. When installing an instant hot water heater, it is important to pay close attention to the plumbing and electrical connections in order to guarantee that the device functions properly.

1. Determine the location of the new hot water heater. It is possible to put the little gadget below a sink on a wall where the hot and cold water supply pipes are easily accessible. Make sure there is at least 12 inches of clear space around the outside of the heater
2. Place the hot water heater against the wall that you want to use. Using a screwdriver, insert four screws into the device’s associated mounting brackets and into the wall to secure the gadget. Place each screw in one of the heater’s four corners on the outside of the heater’s assembly. Pulling on the heater’s exterior assembly will help to ensure that it is tightly against the wall. By hand-turning the valve, you may switch off the water supply to the sink next to it. Check the water knobs on the sink to ensure that the water supply has been turned off. Tube cutters should be used to cut the cold water supply pipe close to where the heater will be installed. To remove a portion of tubing for the Y-future fitting’s installation, cut the same line with the tube cutters a second time around 1 inch below the initial cut region. In the cut section of the cold water supply line, install a Y-fitting to keep the water flowing. A bucket should be placed beneath the Y-fitting so that it may be soldered to the line with a soldering iron. Turn on the water valve if it is not already on. Allow the cold water to circulate through the system and into the bucket for a few minutes. It is used to remove debris and scale from the immediate pipe region, as well as to ensure that the Y-fitting was correctly placed. Reverse the flow of water at the shutoff valve. Remove the bucket from the table
3. Solder the ball valve to the open Y-fitting with a soldering iron. Steps 4 and 5 should be repeated for the hot water supply line. The hot water line’s Y-fitting should be pushed onto a flexible water hose, and the other end of the hose should be connected by hand to the heater’s “hot water out” connection point. To securely attach the hose’s fittings to both connecting locations, employ a compression tool. Step 10 should be repeated for the cold water line. Connect the hose from the ball valve to the “cold water in” connecting point
4. Turn on the water at the ball valve to begin the process. Make sure that the taps are turned on at the knobs and that both hot and cold water are flowing through the new water heater. Check for leaks at the plumbing connection points to ensure that there are none. After the water has been running for approximately 3 minutes, turn off the faucets. Turn off the circuit breaker at the main electrical panel, which will be linked to the heater in a few minutes time. Using a non-contact circuit tester, confirm that the power has been turned off. Connect the electrical cables that run from the heater to the electrical distribution panel. If you need special wiring instructions, see your owner’s handbook. Depending on the manufacturer, each wiring layout is different. Check to see that the hot water heater is working properly by turning on the circuit breaker and running it for a few minutes.

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.

1. Therefore, it may not function well in a family where two or three showers may be operating at the same time, as an example.
2. It is both small and very efficient to use a tankless water heater.
3. 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).
4. There is also the need for a gas line and an electrical connection to a 120-volt circuit.
5. It is not necessary to vent an indoor electric tankless water heater to the outdoors because it is contained within the home.
6. 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.

1. Drain the tank by opening the drain valve located at the bottom.
2. Don Vandervort writes for HomeTips.
3. A segment or two of vent pipe should be disconnected and removed.
4. 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.
5. 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:

• 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.

• 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

• Properly venting the item should be done according to the manufacturer’s recommendations. If your home’s rim joists are in good condition, you may be able to vent your water heater straight through them. Venting should only be done through pipes that have been specifically rated for this sort of application. Depending on the manufacturer, you may require a vent kit. To seal the vent shaft of the new unit, use a heat-resistant silicone sealant. Then, using a hose clamp, attach a connection to the end of the pipe. Put an 8-inch chunk of stainless steel vent pipe on top of it
• Attach a retaining ring at the end of the retaining bar. Folding over the tabs can help to secure it. An elbow is slid into position. 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 to the outdoors. Drill a hole from the inside of the structure at the selected location. The outer wall can be marked with a vent thimble to create a circle. Spade bit a 1-inch hole at the center of the circle, towards the top of the circle. Remove siding and shingles from around the vent hole in order to allow the flange thimble to be flush against the outside wall
• Caulk around the edge of the flange using silicone caulk to seal the edge of the flange with the outside wall. Incorporate the flange into the vent hole and secure it in place. To properly fasten it to the outer wall, use screws that are silicone-coated to prevent leakage. Install the internal flange from the inside out. A portion of vent pipe should be routed through the flange hole. The tabs should be used to secure each portion. A short portion of vent pipe should be connected to the vent hood from the outside. Put the shingles and siding back on the house that you had taken off earlier.

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!

2. Drain Your Old Heater Before Disconnecting It

The tank-type water heater that is now installed in your home will need to be drained prior to being removed from the structure. This will necessitate the use of a hose and a container, such as a bucket. Check out our how-to guide on how to drain a water heater for more thorough information. The old wiring and wall-mounting brackets will need to be removed first, and then the connecting pipes will need to be unscrewed. Be careful not to do any harm to the old wiring or pipes while performing this procedure.

3. Remove the Front Cover

The tank-type water heater that is now installed in your house will need to be drained prior to being taken out of service. A hose and a container, such as a bucket, will be required for this. Check out our how-to guide on how to drain a water heater for more specific information. Before you can remove the old wire and wall-mounting brackets, you’ll need to detach the pipes that link them. Be careful not to damage any of the old wiring or pipes during this operation. If so, they will need to be replaced entirely, which will simply lengthen the project’s timetable and increase its cost.

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.

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.

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

It is more expensive to buy a tankless unit. It will cost around the same as a standard tank type to purchase an electric tankless heater, however a gas tankless heater would cost approximately $1,200 to $1,400. The national average for tankless unit installation is somewhat more than $1,700, which is in addition to the original cost of the system. A safe vent must be created for a gas unit to prevent carbon monoxide from collecting within the residence in many circumstances. Existing plumbing must be expanded or moved in many cases.

1. It is not always the case that a tankless water heater delivers hot water to your faucet more quickly than a traditional water heater, contrary to common belief.
2. While the heating element of a tankless water heater heats water before sending it to a faucet, this process takes time, and the amount of hot water that can be delivered is limited by the unit’s ability to heat the water.
3. As an example, having a shower while also running the dishwasher may cause a tankless water heater to reach its maximum capacity.
4. When comparing tankless models, pay attention to the gallons per minute (GPM) flow rate of each type.
5. A possible option is to install many tankless units in order to cover the needs of a big household, although this might become prohibitively expensive; alternatively, The tankless water heaters will not operate if the electricity goes out.
6. For all water heaters, hard water can be an issue; however, tankless water heaters are particularly susceptible to this problem.
7. They must also be cleansed on a consistent basis.
8. Without taking these precautions, hard water can completely ruin a tankless water heater in less than two years if it is not properly maintained.

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.

How To Install An Electric Tankless Water Heater

Cabins benefit greatly from tankless water heaters. When compared to typical tank water heaters, they are substantially more compact and energy efficient, which makes them extremely popular outside of the United States. They are also ideal for vacation homes and cabins for many of the same reasons they are popular in the United States. Listed below are a few advantages associated with tankless water heaters:

• Small footprint and wall-mountability
• Endless hot water
• Immediate hot water (no waiting for the tank of water to heat up)
• More energy-efficient water heating and reduced energy consumption

The following are some of the limitations of a tankless water heater:

• Large instantaneous energy requirements (electric or gas)
• High initial cost of the unit/installation
• Heating limitations based on flow and inlet water temperature (which can be significant)
• Large total energy requirements.

We were primarily concerned about conserving space. Getting rid of the old, floor standing tank water heater freed up the space we needed to install a new furnace in our little utility room. We were able to get a new furnace in by removing the old, floor standing tank water heater. The modest size and space savings of a wall-mounted tankless water heater are very remarkable — they essentially take up the same amount of space as a suitcase. And, while the space savings are significant, the most significant advantage we have discovered since switching to tankless water heating is the instantaneous, ready-to-use hot water that is there when we arrive.

Tankless water heaters combined with cabins are a marriage made in heaven!

Tankless Water Heaters vs. Traditional Tank Water Heaters:

It was important to us to save as much room as possible. Because we wanted to install a new furnace in our modestly sized utility room, we decided to remove the existing, floor-standing tank water heater to make way for the new furnace. By doing so, we freed up the space we required for the new furnace installation. The modest size and space savings of a wall-mounted tankless water heater are very remarkable — they essentially take up the same amount of space as a suitcase! The most significant benefit we have discovered since switching to tankless water heating is the instantaneous, ready-to-use hot water that is available as soon as we walk through the front door.

When it comes to a seasonal property like our cabin, not having to worry about getting hot water is a major convenience. A pairing made in heaven: tankless water heaters and cabins.

Tankless Water Heater (On Demand)

• Small footprint and little space requirements
• Instant hot water after a time of inactivity – simply switch it on and use it
• It’s just necessary to pay for what you consume (plus a pilot if you’re using gas)
• Unit life expectancy is 20 years or more. Purchase and installation will be more expensive. When in use, they generate a significant amount of energy (40 – 180 amps for electric units and large flows for gas machines)
• Flow (usage) restrictions dependent on the temperature of the source water

Traditional Tank Water Heater (Storage)

• Large size and space requirements
• Complete tank must be heated before hot water is provided after a period of non-use – switch on and wait for the entire tank to be heated
• Large size and space requirements
• Pay for the full tank to be heated (and reheated)
• Unit life expectancy is 10–15 years
• Unit purchase and installation costs are low. When compared to tankless operation, there is a reduction in energy consumption. No matter what the supply temperature is, the temperature remains stable throughout the full tank volume.

Electric vs. Gas Tankless Water Heater Comparison

In most cases, on-demand tankless water heaters are available with one of two fuel options: either natural gas (natural gas or propane) or electricity. When deciding between natural gas and electricity, it is important to consider the prices, performance, installation, and maintenance needs of each.

Electric Tankless Water Heater

• In most cases, on-demand tankless water heaters are available with one of two fuel options: either natural gas (natural gas or propane) or electric. In order to choose between natural gas and electricity, it is necessary to weigh the prices of each against the performance, installation, and maintenance needs of each.

Gas Tankless Water Heater

• It is necessary to have a gas supply, combustion air, exhaust venting, and a 120v circuit. It is not necessary to use 240v high amperage circuits. Install at a location where combustion air, exhaust venting, and a 120v circuit can be accommodated. Installing more sophisticated and costly systems (gas line installation, combustion/exhaust venting installation, plumbing installation)
• Less efficient (usually less than 85 percent efficient)
• When compared to electricity, gas is often less costly. It is possible to have a greater range of heating capacity adjustment (100° – 180°)
• Some upkeep is necessary (burner, pilot, venting)
• Some maintenance is required.

Selecting the Correct Size Tankless Water Heater

It is critical to select the appropriate size water heater. This is especially true with tankless water heaters, which lack a reserve (tank) and are thus obliged to heat the water flowing through them in “real time.” Consequently, tankless water heaters are limited in their ability to heat water as it travels through the unit and are consequently restricted in their ability to heat water as it passes through the unit. Larger units are required for higher flow requirements (large residences, several bathrooms (showers), high flow showers, and so on) as well as for cooler supply water (cold climes, winter use).

• The majority of manufacturers provide charts to assist you in selecting the appropriate size unit.
• Installation of these devices, particularly gas ones, might be prohibitively costly.
• The next sections will walk you through the process of installing my electric tankless water heater.
• As a result of the possible hazard associated with dealing with high voltage, high amperage circuits, you should not try the electrical aspect of this project unless you are properly qualified.
• First and first, safety must be prioritized.
• Before doing any electrical work, be certain that the main breaker panel is turned off.
• If you have any doubts or are not comfortable with this sort of electrical work, you should consult a competent electrician.

Consider the distance between the electrical supply and the plumbing connections, as well as the accessibility for temperature adjustment and maintenance. Consider the distance in plumbing between the heater and the end-of-pipe fittings. Long plumbing runs will result in a greater lag time between the opening of the faucet and the delivery of hot water.

Plan the location of the tankless water heater, taking into consideration the convenience of access to the unit, the simplicity of piping, the distance to the end use (the longer the distance, the longer the lag time for hot water), and the ease of wiring.

Assemble water heater, supplies and tools

Consider the distance between the electrical supply and the plumbing connections, as well as the accessibility for temperature adjustment and maintenance services. Additionally, consider the distance in piping between the heater and the final destination. A larger distance between the faucet and the source of hot water will result in a longer lag time. Think about where you want to put your tankless water heater, including how easy it will be to get to it, how easy it will be to connect it to the rest of your system, and how easy it will be to wire it.

Mount water heater

Position the heater on the wall in the chosen installation position and note the locations of the mounting holes on the wall. Connect the heater to the wall with the bolts that came with it or other suitable fasteners. Unless otherwise specified by the manufacturer, the unit must be installed in the upright position. When choosing a mounting site for a water heater cabinet, provide at least 6 inches around the cabinet for service and space for the cabinet door opening. Install the device upright, in a dry location that is protected from cold temperatures, and away from children.

Plan and Attach Water Connections

• Water connections should be planned and attached. Before going, make sure you are familiar with the local, state, and federal codes. For servicing (inlet filter screen cleaning), the majority of units require frequent water supply line separation
• Thus, they should be plumbed with an attachment that is simple to disconnect and reconnect. This is accomplished through the use of flexible stainless steel connectors. These are the same connectors that are used to connect water softeners and other types of water heaters together. I utilized a Falcon Stainless Mega-Flow Super Water-Flex line that was 3/4 inch in diameter. The use of flexible connections for this arm of the water connection also makes the plumbing process for this arm more simpler. Flexible stainless supply water connection and outlet tubing with a detach connector for easy installation and maintenance. The connection for the outlet (hot water) should also have a detach connection to enable for servicing or replacement to be performed. I made use of a brass connection in conjunction with stiff copper tubing. It will be necessary to use Teflon thread tape or paste on all NPT (normal pipe thread) connections. It is not necessary and should not be done to thread treat coupling connections since doing so might limit the compression of the device and prevent correct seating of the brass interface, which can result in leaks. Make as many sweat (solder) connections as possible prior to assembling the plumbing so that the water heater does not suffer any heat damage. This is especially important if the connections are close to the unit connection. When connecting the unit fittings, use a second wrench to tighten them down. When connecting the unit’s inlet and outlet fittings, take care not to cause rotational damage to the unit’s plumbing by using two wrenches to make the connections between the two fittings. Water should be turned on and checked for leaks once all connections have been completed. Prior to making any electrical connections, check for and repair any leaks.

Plan and Connect the Electrical Circuits

Make sure that the main breaker panel is turned off before beginning any electrical work! Consult state and local statutes and regulations. If you have any doubts, you should consult with a certified electrician who can complete the task. It is necessary to install one to three double pole (240 volt) 40 or 50 amp circuits for your water heater, depending on the type and model of the unit. AWG6 copper wire was necessary for two 50 amp 240 volt circuits in my unit, and for these circuits, I needed two double pole 50 amp breakers (check codes to see whether GFIC protection is required), as well as two double pole 50 amp breakers.

1. Check the wire requirements for your item to ensure that it meets the specific circuit requirements.
2. Take measurements, cut, and connect the conduit circuits that go from your unit to the breaker panel, using the appropriate size conduit (3/4′′ in my instance).
3. According on the length and intricacy of the conduit run, you may find it significantly easier to run the conductors (wires) through the conduit in a sequential fashion as you link the conduits together.
4. Circuits for the Stiebel Eltron unit’s electrical system.
5. Connect the wires to the connections on the unit that correspond to their functions.
6. It is recommended that the connections are labeled with “L1” and “L2” (Live 1, Live 2) or something similar, with the ground connection denoted by a ground symbol ().

Keep in mind that this is two pole wiring, and that each active conductor is considered “hot.” The grounding system for this item is comprised of a single conductor that is attached to the grounding connector.

08/06/2016 Since installing the Stiebel Eltron Tempra 24 plus in our central Minnesota cabin about two years ago, we have been really pleased with its performance. Despite the fact that our cabin has just one bathroom and that the piping for the shower is 3/4 inch and the shower head is set up for maximum flow, the demand for a shower may be quite strong at times. It has been our experience that setting the unit to around 130° in the winter and approximately 120° in the summer produces ideally hot showers and supplies us with all of the hot water we require.

As a result of its location in our warm mechanical room, our reservoir tank’s water ultimately warms up to the temperature of the room in which it is housed.

The ultimate result is a change in the temperature of hot water coming out of the faucet.
