4 reasons why you can install a tankless water heater in the attic

There can be multiple reason why you can install a tankless water heater in your attic. Let’s get to know them.

Safe to use:

In any type of installation process, safety must be a top priority. Heaters produce high temperatures, which makes them a safety concern.

Moreover, tankless water heaters are made in a very compact design. It does not leak and does not emit any excess heat. Installing it in the attic poses no security risks.

Increases efficiency:

Since tankless water heaters do not store water in a hot state, supplying hot water takes longer. Nonetheless, it will not take much time if it can be placed in the attic. Putting it in an attic or on top of a building will allow it to deliver hot water quickly.

Utilize as much space as possible:

It is common for people to leave their attics unoccupied. Installing a water heater will provide two benefits. The first is that you will make use of unused space. You will also be able to save some space within a normal room.

With an attic heater, however, it is necessary to go up in the attic to check on its condition. This will force you to keep the attic clean.

Perfect for the tankless heater:

The success of a tankless heater depends on a limited number of factors. The attic must be kept away from direct sunlight; the sun does not come directly into the attic.

You cannot keep them in an area where rainwater collects, and we know that rainwater does not collect in the attic. Attic seems like the perfect place, doesn’t it?

What is required when a water heater is installed in an attic?

The tankless water heater only requires a few accessories to be installed in the attic. Firstly, you need to construct a frame.

The heater should not be left on the attic floor and should be installed on the roof. You need a frame where you can install it for it to work properly.

A vent hole is required on the roof to allow the excess temperature of the tankless water heater to escape. This will allow the heat to exit the room.

A third requirement is an automatic shutoff switch and a sensor. Sensors are crucial for this type of installation.

The shutoff switch will automatically switch off all the systems if excess heat is generated in the heater and water leaks. In addition, heaters such as inlet and outlet pipelines and electrical connections are required.

Attach the heater with screws to the board and tighten it. Place the heater at least one foot above the attic floor. And keep it at least one foot below the roof.

Vent Hole fitting:

In the roof, cut a hole parallel to the water heater. Attach a vent pipe to the roof, and then attach the other end of the pipe to the heater. Add a rainproof cap to the top of the vent pipe.

Sensor and electrical connection:

Ensure that the safety sensor is properly connected to the circuit. Ensure that the electrical connections are secure.

Automatic shutoff switch installation:

Attach the auto-shutoff switch at the water entrance. If excess heat is generated in the heater, it will instantly shut it down. If you wish to install a filter, attach it to the water inlet.
