Venting Features for Tankless Water Heater

  1. When it comes to venting a tankless water heater, there are two options: direct venting and power venting.
  2. Because it draws in air from outside the building, a direct vent unit is equipped with both an intake and an exhaust vent.
  3. Place the power vent unit in a location where there is sufficient air volume for combustion activities.
  4. In contrast to the previous model, this one simply requires the exhaust vent.

The structural design of the water heater also has a greater influence on the venting options that are accessible to you.Depending on the model, you may be able to vent via a sidewall or through the ceiling.The installation expenses of a tankless water heater that uses condensing technology are less expensive.These heaters contain polypropylene or PVC exhaust vents, which means they are more adaptable to a variety of situations.

  1. Choose a water heater with a concentric vent design for the sake of your family’s safety.
  2. The intake and exhaust pipes of a vent constructed in this manner are insulated.

  3. If you want to make sure that your installation is both safe and convenient in the event that future maintenance is necessary, there are several crucial rules to follow: This product is intended for use only indoors and should not be exposed to the elements.
  4. Installing your unit in an outdoor area may be possible, provided that it is protected from rain, splashed water, direct sunlight, debris and insects through the use of an appropriate enclosure.

A place where this product may be subjected to freezing temperatures is not a good choice for installation of this product.A freeze in the water within your tankless water heater can cause serious and irreversible damage to the unit, which is not covered by the manufacturer’s warranty.If you have reason to believe that your tankless water heater has frozen, do not switch on the heater until it has thawed and you have thoroughly inspected the system for any leaks.If you believe that your tankless water heater may have been frozen with water within it, we strongly advise that you contact the manufacturer immediately for assistance.

  1. When choosing a place for your installation, take into account your current plumbing setup, the position of your main electrical panel, and the location of your bathrooms, kitchen, and laundry area.
  2. Attempt to locate your hot water heater in a location that will not necessitate extensive plumbing modifications, that is close to your main electrical panel (this will reduce the amount of wire that needs to be installed), and that is physically close to the hot water applications (faucets) that you use the most frequently.
  3. It will take less time for hot water to get from the water heater to your faucet if you place the water heater near where you will be using the water.
  4. You should also think about how you will maintain your vehicle in the future.
  1. The water heater should not be placed in a location that is difficult to reach or maintain.
  2. It will make the most sense in most circumstances to install your tankless water heater in the same position as your old traditional tank-type water heater.
  3. In any case, regardless of where your water heater is put, it should be installed in such a way that flammable objects do not come into contact with the water heater or the outlet water line.
  4. Combustible objects should be maintained a minimum of 24 inches away from your water heater and the hot water line that delivers the hot water.
  5. Although the lid of your water heater may only become slightly warm to the touch during regular operation, it is always important to be extra cautious when working with a high voltage device.
  1. In order to prevent youngsters from tampering with the temperature controls or injuring themselves by touching the hot water outlet pipe, make sure that the water heater, electrical sub-panel, and outlet hot water pipe are all out of reach.
  2. It is possible for the output water line to get extremely hot.
  3. This product does NOT require venting.

You should avoid putting your tankless water heater in a place that is subject to high humidity, moisture, or dust, or in a location where it may be splashed with water or other liquids, as this can cause damage.Do NOT place under water pipes or air conditioning lines that can leak or condense moisture that could then drip onto the heater.Installing above electrical boxes or connectors is not recommended.In the event that you intend to put your water heater on a second story or in a heated attic space, be certain that you adhere to all applicable code requirements for such installations in your local jurisdiction.A drip pan (attached to a safe drain) should be installed below the water heater in order to prevent property damage in the unlikely case of a leak.

An alternative solution is to put in place a functioning water leak detector and shut-off valve that will automatically cut off your water supply in the event that a leak is discovered (we recommend: www.a-leak-detector.com).Return to the Installation page This is the main page of the website.

  1. In the case of this question, the answer is no.
  2. Choose a tankless water heater type that is intended for indoor installation when installing a tankless water heater inside your home.
  3. The majority of manufacturers have versions that are intended for either outdoor or indoor installation.
  4. Rinnai, for example, provides a product line that includes versions of both sorts of engines.

It is only possible to install the Rinnai RUR e Series Sensei series in an outdoor setting.The Rinnai RUR Series Sensei line is designed only for indoor usage.There are some variances in the way they are designed.An outdoor system does not require venting, but inside systems must.

  1. This is the fundamental difference between the two systems.
  2. Additionally, the design of an outdoor tankless water heater unit can endure extreme weather conditions better than the design of an interior tankless water heater unit.
  3. As a result, you cannot use an indoor model outside or an outdoor model inside.
  4. As a result, it is critical to establish whether you want an indoor or outdoor tankless water heater before making a purchasing decision.
  1. It is also important to remember that tankless water heater maintenance will be required regardless of the type.
  2. Make certain that there is enough space to service the unit by keeping the clearances free.

Why Install a Tankless Water Heater Inside?

If you have a limited amount of available space in your home, placing a tankless water heater outside appears to be the best option. However, there are several reasons why it is not a good idea to get an outdoor model.


  1. The meteorological conditions in your area are the primary cause behind this.
  2. The potential of damage to an outside tankless water heater increases if you live in an area that is prone to freezing.
  3. Freeze protection is integrated into all outdoor tankless water heaters.
  4. However, there is an issue with the way the protection is implemented.
See also:  How To Install Rheem Electric Water Heater?

The electricity that powers the freeze protection device is required to operate.As a result, if your power goes out in freezing weather, the freeze protection will not be able to function.That’s a big issue since those situations have the potential to cause damage to your system.There are measures you may take to get around this, but there may be a cost associated with doing so, so plan accordingly.

An Outdoor Unit May Affect the Aesthetics of Your Property

  1. Outdoor units are often installed on the outside of a house’s outer wall.
  2. You should try to locate it in a nondescript outside area if possible.
  3. Installing it somewhere else may have a negative influence on the curb appeal of your home.
  4. Even if you have a suitable site for your unit, it may not be ideal for its installation.

In order to comply with national code criteria established by the American National Standards Institute and the National Fuel Gas Code, you would need to hire a professional.Because all manufacturers are required to adhere to national codes, your user handbook should provide specifics on them.Local building agencies may also have certain rules that must be followed.For example, there may be limits on how near you may place your installation to door and window openings.

Where Is the Best Indoor Location for a Tankless Water Heater?

  1. Tankless water heaters are tiny and portable, generally measuring no more than the size of a small suitcase.
  2. Thus, when it comes to selecting a place, you’ll discover that you have a variety of possibilities.
  3. However, if you’re replacing an existing heating system, it makes sense to install your new tankless heating system in the same location.
  4. In the absence of that, here are some things to think about:

Clearance Requirements

You’ll need to make sure you fulfill any clearance restrictions that the manufacturer may have. As a result, see your user handbook.

Install On or Close to an Exterior Wall

  1. For your tankless water heater, you may install it within interior walls.
  2. However, due of the ventilation needs, mounting it to an external wall is the preferable alternative.
  3. We’ll get to those in a minute, but it’s generally easier to vent these systems via a wall than it is through a roof, which we’ll discuss later.
  4. If you are unable to attach your unit to an external wall, you can attach it to the inside side of an exterior wall.

Please consult your user handbook to verify that you do not exceed the maximum lengths specified by the manufacturer for vent pipes.An electric tankless water heater will almost certainly necessitate the installation of new wire lines to the electrical panel box or the installation of a dedicated subpanel.Depending on the size of the electric tankless water heater, you may require as many as three 220 volt circuits to power the device properly.An indoor gas tankless water heater will require ventilation to the outside, which is commonly accomplished through an outside wall.

  1. In some cases, though, it may be necessary to vent through the roof.
  2. If you want further information, speak with your plumbing contractor.

Put It Close to Gas and Water Inlets and Power Source

  1. Tankless water heaters should be installed in a place that is convenient to existing gas and water supply connections.
  2. It will also need to be in close proximity to a power source.
  3. As a result, you will save money on installation costs because you will not have to add plumbing and cabling.
  4. The costs of doing so might quickly add up.

There is also the issue of disturbance if the job entails passing through walls within the building.

Proximity to Hot Water Appliances

In order for your tankless water heater to operate as effectively as possible, it should be installed as close as possible to the appliances that utilize hot water. As a result, heat loss via the pipes will be reduced since the hot water will not have to travel as far to reach its destination.


  1. If you’re using natural gas or propane to heat your water, you’ll need to vent your tankless water heater.
  2. Ventilation serves two critical purposes.
  3. First and foremost, it provides air for the combustion process, which is responsible for heating the water.
  4. Second, it eliminates the potentially hazardous waste gases.

In the case of an indoor gas-powered tankless water heater, you’ll have a choice between two different venting options.That is the difference between power-vent and direct-vent.


  1. The combustion process in a power-vented system is carried out with air from the inside.
  2. As a result, there is no requirement for an air intake vent.
  3. Although this sounds fantastic, you would still need to expel exhaust gases to the outside.
  4. You’d also have to place the device in a well-ventilated area with enough internal air to burn the fuel within the appliance.

As a result, if you have a restricted amount of room, this may not be the best option.


  1. Whenever possible, direct-vent models are the most suitable choice in smaller areas with little space available.
  2. These types suck in combustion air from the outside using a direct-vent system.
  3. As a result, direct-vent units do not require a lot of floor area.
  4. Once again, you’ll need to expel the exhaust gases through an outside hole.

Despite the fact that we’re talking about two vents, one for air and one for exhaust gases, you don’t need need two pipes to complete the setup.You may use concentric pipes to do this.A stainless steel inner chamber holds the exhaust gases, while a polyurethane (UPVC) outer chamber holds the air.Not only is it more aesthetically beautiful, but it also means that you only need a single hole for the venting to function properly.

  1. That will help you save some money.
  2. Tankless water heaters may often be vented vertically or horizontally, depending on the model.
  3. However, keep in mind that with some, it’s either one or the other option.
  4. Unless you’re installing your tankless system in an attic, horizontal venting via an outside wall is likely to be less disruptive than vertical venting.

For Increased Flexibility, Consider Electric

  1. If all of this talk about venting makes you uncomfortable, you might want to investigate an electric tankless water heater.
  2. Models that run on electricity do not require venting.
  3. This is due to the fact that there is no combustion process involved in heating the water.
  4. As a result, you can install an electric tankless water heater virtually anyplace in your home.

If an electric model can handle your hot water requirements, it is worthwhile to investigate this alternative.


  1. So now you know that if you purchase a tankless water heater that is built for indoor usage, you may put it inside your home.
  2. A number of considerations must be made while determining the best location for the system installation.
  3. However, it is not as frightening as it appears.
  4. Investing the necessary time to achieve a proper installation will ensure that you get the most out of your system.

Installing a tankless water heater next to electric service panel

  1. In the course of constructing an outside natural gas tankless water heater, I’ve come across this website.
  2. The problem I’m having is that there aren’t enough space around the heater.
  3. A little location on the back wall of the home would be ideal for it to be fitted.
  4. According to the installation instructions, the exhaust vent must be at least 12 inches away from the unit ″away from an open window, but in order to achieve this requirement, I would have to put it directly next to my main electrical service panel, which is located right next to my kitchen sink (and electric meter).

The only regulatory requirements I’ve discovered for clearances around electrical panels are that there must be at least a 30 inch gap between the panel and the wall ″a place to work (side to side).If the panel can be placed anywhere within that 30″ border, then I believe I can put the heater pretty much right next to it, as long as there is enough space on the other side to get me up to that 30″ barrier.Here is a graphic that illustrates the measurements taken on the house as well as a schematic that explains how to comply with the electrical code in this situation:

What Is the Setback From a Window for a Tankless Water Heater?

  1. The use of a tankless water heater is an energy-efficient choice for households.
  2. Because the machine heats the water just when it is needed, rather than heating and storing it at a fixed temperature, it consumes less energy than a traditional boiler.
  3. In order to properly install a gas or propane tankless water heater, you must first determine the particular setback requirements for windows.
  4. These requirements vary depending on the location and whether the unit is installed indoors or outside.

Indoor Installations

  1. Except when it is directly vented to the outdoors, a tankless water heater must have at least 4 feet of space on each side or below a door or window that opens to be installed.
  2. If the water heater is positioned above a door or window, it will require a minimum of 12 inches of space.
  3. Installation of a direct vent requires only a 12-inch space between the vent and the door or window.
  4. If the window cannot be opened, the water heater will require a 12-inch setback from the wall.

Outdoor Installations

  1. The only climates in which outside installations are appropriate are those with moderate winters and temperatures that do not drop below freezing.
  2. It is necessary to have a minimum of 12 inches clearance between the tankless water heater and any operable door or window when it is installed on the exterior of the house.
  3. The distance between a working window and an inoperable window varies depending on the local construction codes.
  4. In addition, an outside vent cap is required for the unit.

Other Considerations

  1. Additionally, tankless water heaters should not be located near dryer vents or intake air vents, in addition to the setbacks for windows and doors mentioned above.
  2. It is not permissible to put the heater directly across from a window or door in a neighboring building if the heater is located between two buildings with a minimum distance of 2 feet between them.
  3. When the unit or vent is situated over a paved road or sidewalk, it must be at least 7 feet above the ground level.

Additional Requirements

  1. Your local building standards may have extra setback requirements that are in addition to the minimum requirements listed above.
  2. Before a tankless water heater can be installed, it must first be approved by the local building department.
  3. As an added precaution in California, all water heaters are required to be braced, anchored, or lashed to the wall studs in order to guarantee that they do not move during an earthquake.

Codes for a Water Heater in the Closet

Because most residences do not have a basement or garage, it is important to put the water heater somewhere inside the structure of the house. It is frequently preferable to do it in a closet where it will not be seen. Nonetheless, this is only permitted in limited circumstances, and a permit is necessary when installing, replacing, or repairing a water heater.

Water Heater Types

  1. Water heaters should be built in areas where they can be conveniently connected to gas or electric service, as well as where water supply and distribution lines can be simply erected.
  2. If the unit is positioned on an external wall, it will be easier to provide proper ventilation.
  3. In the event that a water heater is required or desired, it can be put in a bedroom or bathroom closet, but only if it is an electric, direct vent, or sealed combustion chamber type.
  4. Other types of water heaters that employ fuel combustion are not authorized to be put in bedrooms, bathrooms, or closets that have doors that open into these areas.

Closet Doors

When a water heater is put in a closet, the doors must be closed; the doors cannot be left open at any time. If the doors are left unattended, they must open and close smoothly and freely, and they must close and lock on their own. It is not permissible to include features that allow the closet door to be held open. Under the closet doors, there must be a threshold and a seal installed.

Air Circulation

  1. Water heaters need a particular amount of clearance, or air space, around them in order to perform correctly and securely.
  2. A hot water heater must have a clearance area of 12 inches on all sides in order to function properly.
  3. In order to provide optimal combustion and ventilation, a specific quantity of airflow is also necessary.
  4. It is required by the building code that adequate airflow be given for these operations in accordance with the manufacturer’s requirements for the unit that is being installed.

One combustion air opening must be built within 12 inches of the top enclosure of the water heater, and another must be put within 12 inches of the bottom enclosure.The diameter of the air ducts necessary for combustion must be at least three inches.

Seismic Straps

  1. It is possible for a water heater to shift during an earthquake, resulting in water leaks, gas leaks, and electrical damage.
  2. Water heater bracing straps must be fitted on water heaters in earthquake-prone locations in order to avoid this.
  3. Both the top and bottom thirds of the water heater must be secured with two straps, with one strap situated on the top third and the other located on the bottom third of the water heater.
  4. There must be at least 4 inches of space between these straps and the water heater’s controls.

When connecting units to gas and water sources in seismic zones, it is necessary to use flexible connection hoses to avoid damage to the units.

3 places you should install a point-of-use tankless water heater

  1. There are three locations where you should put a point-of-use tankless water heater.
  2. Water heaters that are put near to the faucets or appliances that require hot water are known as point-of-use tankless water heaters since the unit is committed to only one area and provides a consistent supply of instantaneously heated water.
  3. While this may appear to be a costly option, point-of-use tankless heaters can really save you money if they are used properly..
  4. Take a look at these three areas of your home where a point-of-use tankless water heater might make a significant difference in efficiency.

1.Taking a shower While a cold rinse after a workout or on a hot summer day may be soothing, most people prefer to wake up to a steamy shower during the rest of the year.Traditional water heaters, on the other hand, can be overworked by someone running a sink below or flushing a toilet, resulting in a sudden rush of ice cold water flowing down your back and out the other end!Point-of-use tankless water heaters almost ensure a consistent supply of hot water for your morning showers for a variety of reasons.

  1. Here are a few examples.
  2. First and foremost, there is no additional demand placed on the heater other than that of the shower user.
  3. Second, the greater the distance between your shower and your typical heater, the greater the amount of heat that will be lost via the walls of your home.
  4. According to the California Energy Commission, between the 1970s and now, the distance between the heater and the farthest hot water fixture has risen from 30 to 80 feet, meaning that it now takes three times longer to acquire hot water from a typical heater than it did previously.
  1. When placed directly to the shower’s incoming water supply, point-of-use tankless heaters ensure that there is no lag between water source and destination temperature.
  2. The second is the washing machine.
  3. If you’re interested in making your house more environmentally friendly by installing a tankless water heater, it’s likely that you’ve looked at ways to make your washing machines more energy efficient.
  4. Forget about front- or top-loading washers, and instead pay attention to how much hot water your washing machines consume.
  5. It is estimated that merely two loads of laundry per week will result in the typical washing machine using more than 5,000 gallons of water per year, according to the Jetson Green blog on energy efficient living.
  1. If you do your laundry at home with your complete family or if you need to wash specific garments for a longer period of time, you may anticipate this figure to rise.
  2. Even if you only use cold water occasionally, your washing machine places a significant strain on your home’s infrastructure, and your water heater must always be switched on, using energy and costing you money, if you want a fresh load of clothes.
  3. Using a point-of-use tankless water heater, your washing machine will only consume the amount of water that it requires at the time of usage.

With a low-flow washer and an Energy Star-certified appliance, Jetson Green estimates that you may save anywhere from 2 to 5 percent on your annual water bill when you combine the two strategies.The kitchen sink is number three.There’s an old phrase that goes, ″Everything, except the kitchen sink.″ When it comes to point-of-use water heaters, though, the faucet in your kitchen should surely be considered as a potential contender.According to the Environmental Protection Agency, the average household faucet consumes around 2 gallons of water every minute on average.If you’re doing the dishes or cooking and forg
