Which is the better choice – keep using an inefficient unitheater, or investing in a new, more fuel-efficient unit heater?

Anthony and Jason Calverley, owners of Calverley Supply – an HVAC Distributor in Sterling Heights, Mich. — stock and sell Reznor Model UEAS unit heaters, and promote them for their high-fuel efficiency. They decided to test them in their own warehouse.

During the winter of 2007/2008, they kept track of the natural gas used by two unit heaters. The next year they replaced them with two Reznor Model UEAS 90%+ efficient unit heaters. The results were overwhelming. They calculated that they used 23.8% less fuel, saving more than $800 in four months.

Jason Calverley said, “It was difficult to believe thesavings when they were first calculated, but seeing the difference on our monthly gas bills is enough evidence for us. We are going to continue replacing the units in our own buildings with the Reznor Model UEAS unit heater. It just makes good financial sense.”
