Intallation Tips For A Tankless Water Heater


Upgrading to a tankless water heater means that you must find the perfect location for it. The following installation tips can help.

1. Consider the Clearance

Clearance is very important when choosing the best location for the water heater. Tankless heaters are small enough to fit in a closet or large cabinet, but these small spaces are only suitable if they provide enough clearance on all sides of the water heater to allow for proper air circulation. Clearance needs vary depending on the make and model of the tankless heater, so always check with the manufacturer.

2. Choose the Right Water Lines

Don't try to simply reuse water lines from your old tank heater, especially if your tankless heater will be providing hot water to multiple fixtures. Old lines may be too narrow for efficient water delivery. Instead, replace the water lines with wider lines. This extra width can supply sufficient water to more than one fixture without taxing your tankless heater.

3. Don't Overlook Venting

Venting with a tankless heater is vital. Generally, vents will be designed to penetrate through the ceiling and roof, or they will need to pass through a wall. Many manufacturers recommend limits on the length of a vent, as overly long vents may not allow fumes and heat to dissipate out of your home properly. This recommended length will need to be verified before determining whether you want a roof or wall vent. In some cases, vent fans can be added so a long vent pipe can be utilized if needed.

4. Use a Backer Board

A tankless water heater needs to be mounted onto the studs, otherwise, it won't be properly supported and it may come detached. Although most heaters come with mounting brackets, the width of the mounting system may not line up perfectly with your studs. Solve this problem by mounting a plywood backer board onto the studs in your installation location. The tankless heater can then be safely mounted directly to the well-supported plywood.

5. Plan For the Fuel

What type of fuel will your water heater use? Most tankless heaters use either gas or electricity. If you have a gas heater, you need to make sure you can safely have gas lines run to your preferred installation location. Generally, it's less expensive if you install the heater near existing gas lines as opposed to running new lines. Electric heaters are typically easier to install since most rooms in a home already have electricity running into them.
