High Effeciency Single Stage Pump

A single stage furnace is not as efficient as every time it turns on, its working at full blast to produce as much energy as possible.2-stage more efficient than 1 stage.So, you have probably already guessed that a 2-stage furnace has 2 levels of output-high and low.Most of the time the furnace runs on the low setting and only kicks into.
