Hi,
I did read an article (Norwegian one) about heat pumps. Several owners claims that the annual costs for operating a heat pump versus a traditional electric stove isn't much different. Even if the heat pump isn't reversed at hot days in the summer (And used solely for heating), these owners say that the cost might also be slightly higher than using electric stove. Also even if the average temperature inhouse isn't changed.
So my questions are: Are these COP numbers not real? Are they in practice about 1 or less?
It appears to me that the technology isn't as efficient as I thought it was.
Do you have theories or facts that supports these claims?
Just good to know before I decide to install a heat pump.
A quote using google translate:
"Now an analysis from Statistics Norway (SSB) that heat pumps may not be as environmentally friendly as you thought. If one is to believe SSB, they contribute at least not to lower the overall power consumption.
Households with heat pump has in fact on average about the same power consumption as other households, it is going ahead SSB analyzes 2/2013."
