Tankless water heater

How should a Home Inspector inspect a tankless
waterheater ?

New to the business


Most tankless water heaters are sealed units. If you remove the cover, you may void the warranty.

Do the inspection of the tankless as you would a standard water heater. Do check the exhaust flue and make sure that there is additional clearance around it. The required clearance information can be found in the manufacturer’s installation guide.

And for gas powered tankless water heaters, ensure that proper make-up air is present…these things can consume more air that some furnaces.
