Is it better to install a tankless water heater inside or outside?

The answer to this question depends on several factors. When deciding whether to install a tankless water heater inside or outside, you should consider the size of the unit, the environment it will be working in, and your local building codes.

A tankless water heater can be installed either inside or outside, but installation inside of the house tends to be more common because of the convenience. Generally, if the unit is small enough to fit through doorways and walls, it can be installed indoors.

An indoor installation is also beneficial if cold temperatures or freezing temperatures can be an issue, as the temperature of the incoming water can be controlled better when the water heater is in an enclosed space.

If the unit is too large to fit inside the home, or if you live in an area with warm temperatures year-round, then installing the unit outdoors is the preferable option. An outdoor installation also gives you easier access to the unit, meaning it requires less work when the unit needs to be serviced.

Ultimately, whether to install a tankless water heater inside or outside depends on the size of the unit, your local environment, and the city or state building codes. It is a good idea to speak with a professional plumbing contractor to discuss the best option for your particular situation.

Can tankless water heaters be placed outside?

Yes, tankless water heaters can be placed outside, but there are a few safety considerations to take into account first. Firstly, make sure the area around the heater is adequately protected from the elements, as tankless water heaters need to be installed in a sheltered area away from rain and snow.

They should also be placed firmly on a level surface, as any moisture or condensation can cause problems with the electronics. Additionally, tankless water heaters should never be placed directly on dirt or grass, as this could cause them to overheat or rust.

Finally, they should be connected to a gas line, with all fittings checked regularly and any exposed pipes insulated during cold weather. By making sure these safety considerations are taken into account, it is possible to safely install a tankless water heater outside.

What is one disadvantage of a whole house tankless water heater?

One of the main disadvantages of having a whole house tankless water heater is its upfront cost. This type of water heater is more expensive than a tank-style water heater, so it could put an initial strain on your finances.

Additionally, the installation process can also be more difficult, which could lead to increased labor costs. If you have a larger home, you may also need multiple units to make sure that the water heats up efficiently throughout the entire home.

This would add to the overall cost, as well as the installation. Another disadvantage is that tankless water heaters often require a powerful gas line to operate, so you may need to upgrade your existing gas line before the installation, adding to the overall cost.

Why do people mount tankless water heaters on the exterior of a home?

People mount tankless water heaters on the exterior of a home because it is the best and safest way to properly vent the exhaust gases that are created when the heater is in use. Tankless water heaters run on natural gas, and to keep carbon dioxide levels safe, the exhaust must be vented outside of the home.

Interior venting is possible, but it increases the risk of carbon monoxide leaks, which can be deadly. Mounting the water heater outside is a much safer alternative as it ensures the exhaust is properly vented and away from the home.

This can also help to maximize the efficiency of the unit since it is not competing for air space with other appliances in the home. Additionally, mounting the water heater outside may give you more space inside your home.

How close can a tankless water heater be to a wall?

When it comes to the installation of a tankless water heater, the general rule of thumb is to allow for a 3” clearance from a wall to the front of the tankless water heater unit. This is necessary to allow for proper air intake and combustion air, as well as preventing damage to any vents that are present on the unit.

Generally, most tankless water heater units will come with an exhaust venting kit that can accommodate up to 5” from a wall, but that is dependent on the size of the vent kit supplied. It is always best practice to check the manufacturer’s specifications and ensure the proper clearance is met prior to installation.

Additionally, it is important to ensure there is clearance on the sides and back of the tankless water heater to allow for maintenance and repairs. Most units require at least 6” of clearance on the side, and 2” on the back.

How much room do you need around a tankless water heater?

In order to ensure the safe and efficient operation of a tankless water heater, there should be at least six inches of clearance around the unit on all sides for maintenance, ventilation, and air circulation purposes.

Additionally, it’s important to make sure the area around the tankless water heater is well-ventilated, so the surrounding area should have several openings to provide adequate air movement, such as a window, exhaust fan, or other ventilation source.

It’s also important to keep combustible materials and flammable items, such as paint or fuel, away from the tankless water heater as it may lead to a fire hazard. Additionally, it’s important to verify that all combustible materials, such as walls and vents, are located at least three feet away from all sides of the unit.

Lastly, a tankless water heater should never be blocked or covered, as any blockage or cover will impede the tankless water heater’s heating capability, lead to a reduced lifespan, and create an accumulation of flammable materials.

Can you install tankless water heater anywhere?

Yes, you can install a tankless water heater anywhere in your home as long as there is adequate gas, water, and electrical supply to meet the requirements of the unit. When installing a tankless water heater, it is important to make sure there is adequate ventilation for proper combustion and sufficient clearances around the unit in order to prevent any potential hazards.

For a more detailed overview of installment prerequisites, it is recommended to consult a certified plumber or other professional with experience in tankless water heaters.

Can you take a long shower with a tankless water heater?

Yes, you can take a long shower with a tankless water heater. Tankless water heaters provide an unlimited supply of hot water since they heat water as it is needed. Because of this, there is no limit to how long you can take a shower.

In fact, with a tankless water heater, you can shower for as long as you like and still not run out of hot water. When compared to a tank water heater in which a predetermined amount of hot water is stored, a tankless water heater will provide you with an endless supply of hot water.

However, it’s important to note that tankless water heaters require more time to heat up water than traditional tank water heaters. This means that if you take a long shower you could experience a decrease in water pressure due to the increased time it takes to heat the water in the tankless unit.

Does location of water heater matter?

Yes, the location of your water heater does matter. The ideal scenario for a water heater is to locate it in an area that will allow it to perform efficiently and safely, and where the heater can be serviced easily.

The most common recommendation is to place it away from areas where there is excessive moisture, such as bathrooms and laundry rooms. The water heater should be located in an area of your home that will be well ventilated, to help it perform efficiently and to prevent any gases from accumulating.

It is also important to consider the size of the water heater when deciding on its location. If the water heater is too big for the space, it can cause a safety hazard and make the operation of the unit more difficult.

The location of the water heater also affects its performance. If it is too close to the water supply line, it could cause a pressure drop, resulting in lower water pressure in other parts of the home.

Finally, make sure you know how to access the water heater for regular servicing and maintenance. When it’s nicely tucked away, it can be hard to get to and by the time you do, it may be too late.
