Not all water heaters are installed in the same location. Some homes have their water heater in the garage, whereas others have their water heater in the crawlspace or basement. Alternatively, the water heater may be installed in a separate closet. So, does the location of the water heater really matter?

Yes, the Location Matters

When it comes to water heaters, the location absolutely matters. Water heaters, of course, are designed to heat the water in a home. The location in which a water heater is installed may affect its performance, efficiency and safety.

Building Codes

There are building codes that govern the location of water heaters. You can’t just install a water heater anywhere in your home. Rather, you’ll need to comply with local building codes.

Ventilation

Depending on the specific type of water heater, it may require ventilation. Some water heaters produce exhaust gases as a byproduct of heating the water. These exhaust gases must be vented to the home’s exterior. Therefore, these water heaters are usually installed on an exterior wall.

Space

There needs to be enough space in a given area to accommodate a water heater. Some water heaters stand over 70 inches tall. Tank-style water heaters, though, are typically taller and bigger than their tankless counterparts. If you’re planning to invest in a tankless water heater, you can choose a smaller space thanks to their compact design.

Maintenance

Water heaters must be installed in a location where they can be accessed for maintenance purposes. All water heaters require maintenance. You’ll need to get your water heater professionally inspected. If it has a pilot light, you may have to relight it. If you can’t easily access your water heater, you won’t be able to properly maintain it.

Pipe Distance

Another reason the location matters is pipe distance. Whether tank or tankless, all water heaters must transfer heated water to faucets and showerheads via pipes. Installing a water heater near these faucets and showerheads will result in shorter pipe distances. The heated water won’t have to travel as far, resulting in improved efficiency.

Insulation

Some water heater locations are better insulated than others. Insulation is particularly important for tank-style water heaters. Tank-style water heaters work by storing heated water in a tank. If there’s little or no insulation around a tank-style water heater, it will have to consume more energy to keep the water hot.
