I am wanting to know how you can tell the difference between a single stage heat pump and a multi stage one.?
My house was built in 1999 (7 years ago) and all I know is that I have a heat pump. Can someone PLEASE tell me how to distinguish between a single and multi stage heat pump. I am considering buying a Digital thermostat for my home. Any information will be greatly appreciated! Thanks in advance. =)
“All heat pumps that have an alternative heat source such as electric ,gas or oil furnaces are multi stage. What happens is when your heat pump cannot keep up with the heat loss in the house it will lock out and bring on a second stage which is the electric strips or gas burners in your furnace.”
Interesting answer, but completely wrong.
The “stage” for a heat pump has to do with the compressor – it may have two speeds, it may run with one cylinder in one direction and two cylinders in the other, or the unit may have two compressors. The second “stage” is used when the demand is high. This allows for greater efficiency.
That said, the other answers are correct (except for JamaicaJoe – he is obviously not the sharpest tool in the toolshed.)
