How To Install A Tankless Water Heater
If you make the upgrade from a tank water heater to a tankless water heater, you'll save space and produce hot water more efficiently. However, tankless water heater installation requires a more in-depth installation that involves swapping out a hot water tank with another hot water tank.
Upgrade Your Gas Line/Electrical Panel
You need to have a steady gas line or electrical flow to power your tankless water heater, which may require an upgrade to the gas line or the electric panel. You may need to pay for professional services, such as an electrician, in addition to the water heater technician. If required, this will make up a large portion of the installation costs for your new tankless water heater.
Remove Old Water Heater
You probably plan to use your new tankless water heater to replace your old water heater, unless you're building new construction. The old water heater may be in the way of the new water heater. At the very least, it will be taking up space.
Your water heater technician will disconnect and remove the old water heater for you. Alternatively, you'll have to disconnect it and take it to the recycling center yourself.
Mount Tankless Water Heater
Now, you can secure the tankless water heater in place on the wall using mounting brackets and nails. The placement must adhere to all local plumbing codes. Some plumbing codes require a specific amount of space around each unit. It's also best to place it somewhere convenient for ventilation, or you'll have to pay for additional tubing and leave more room for leaks.
Tankless water heaters have several connections that will need to be considered:
- Water supply - where water enters the water heater.
- Gas supply - where natural gas or propane enters the water heater.
- Hot water distribution system - pipes that transport hot water to different fixtures and appliances throughout a house.
Verify Settings and Test New Unit
With the new water heater in place, you'll want to configure the settings to your preferences and test that your new unit works.
In order to test the unit properly, you'll want to remove any other water heaters on the system and run the hot water from all of the different fixtures around your home.
Assuming everything works properly, you'll register your warranty with the manufacturer and get preventative maintenance on your new unit once a year to remove sediment buildup inside of the unit.
