Rinnai America Corp. offers a new program for contractors, dealers and installers — $200 in cash for every traditional tank-style water heater they replace with the Rinnai RH180 hybrid tank-tankless water heater.

It is for emergency replacement or for users looking to increase their hot-water supply without reconfiguring their current set up. The 91,500 Btu heater produces more than 180 gal. of hot water in the first hour.

The Ultra Series’ design of commercial tankless water heaters from Rinnai incorporates two heat exchangers to achieve greater water-heating value from every cubic foot of natural gas or propane.
