I have just read an advertisement that is trying to sell heat pumps-I don't think the brand really matters but they say with 1KW input they can produce 5KW output. Now I understand there is a portion of "free" heat shell we say by the very nature of the system but an extra
4KW seems abit much- So my question would be is this the normal amount expected ie- 1KW in--5KW out. Now I have read the little fine print it says that the input is 1KW (230V/4.3A) but the KW output is in what they term as heat output. Are these two terms the same?cdd
