Are there tax credits available if I purchase a Rinnai tankless water heater?

The Energy Policy Act of 2005 established tax credits for energy improvements to existing homes. If you choose a tankless gas water heater, hybrid gas water heater or natural gas tankless water heater which has either an energy factor of at least 0.82 or a thermal efficiency of at least 90%, you may be eligible for up to $300 in tax credits. Check directly with Energy.gov or your tax professional to learn more about a potential credit.
