Where To Install A Water Heater In A New Home

Posted on

If you are building a home, you are already aware that you will need a water heater installed to keep a steady flow of warm water throughout the property. However, you may be less sure about the importance of the placement of the water heater. The layout of each home is different, as are its demand needs, so there is no perfect location. Yet, there are some factors to keep in mind to help you find the ideal placement in your home. 


A traditional, tank water heater can take up a significant amount of space. If you are building a large home, and need two systems, they will take up double the space. The water heater must have space for ventilation, and it must have space on all sides for a technician to access. Whatever location you choose, make sure there is adequate space. 

Tankless Water Heaters

If you have plans to install a tankless water heater you may need to consider the placement of more than one heater system. Tankless water heaters have several advantages, but a single unit may not be able to meet the demands of a large home. As you map out your plans, factor in placement for two of these systems on opposite sides of the property. 

Building Codes

You will need to adhere to any building codes outlined by your county or state governments. Failure to adhere to these guidelines can lead to a violation and delay the completion of your home. For example, in some states, all water heaters must be installed against an external wall to meet proper code. A plumbing professional in your state will be well-versed in the local building codes so they can assist you with this step.

Damage Potential

For homeowners who do not stay on top of maintenance, water heater placement in a location that is out of sight, such as an attic, comes with a risk. If proper maintenance is neglected and the heater is in the attic, it could have a leak or other issue that goes undetected for quite some time which can cause serious damage to your home. Staying on top of maintenance is best, but a location where you can periodically check on the unit is also helpful.

While you can use this guide, you are not required to make this decision on your own. A plumbing professional can assist you with deciding where to install the water heater in your new home.
