What is the payback period for a tankless hot water heater?
A – The more flow needed, the more efficient tankless hot water heaters become. Payback periods for THWHs run from 5.5 to 11 years in low-flow situations (68.8 gallons/day) to 3 to 7.5 years in high-flow situations (250 gallons/day). This range is dependent on what your municipality charges for water utility. Also, one must consider that Tankless Hot Water Heaters last 2 to 3 times longer than conventional hot water heaters, thereby saving replacement costs.
