I have an elect heat pump it does not seam that it can keep up to the needs that we want. Does that mean that some thing is wrong with my pump. Need help
thanks, chuck
*Something might be wrong with it or it might be undersized. Has it ever kept up with demand with the same outside temperatures? If it has, then something which once worked doesn't anymore. It could be low on freon, need the HX cleaned, the various setpoints adjusted, the electric-heat mode (in coldest weather) may not be kicking in, etc. Get a local HVAC firm with heat pump experience to check it out.If it has never kept up with demand (or has never been tested to point when you noticed a problem), it may be undersized for your application. Use a heat loss calculator (many discussed in the archives) and compare your answer to the units rating. Note that any heat pump can provide more heat when the outside temperature is high than when the outside temp is low (unfortunately, that's when you need the most). A separate issue is, when it is cold enough to switch from heat pump to electric resistance heat, if the electric resistance heating is of a high enough rating to keep up with your coldest days. -David
