This is the first on demand water heater we have owned. We were buying 700-900 gal. of Propane a year. After installing the 40H it cut our bill in half. We had a computer board problem and notified the company as our unit is still under warrenty. The company shipped out a new board. I installed it upon receipt and we are back in hot water. I would recomend one of these units to anyone who wants to cut there propane bill.
