Have you checked that the unit has the proper amount of refrigerant in it?

Think I paid £340 for it so not expensive at all.
It achieves COP 2 so according to my electric meter it will have paid for itself vs resistance heating in the next month or so.
Can't find the Chinese site now, but I did see an identical heat pump made in China with the same model number that claimed -15C operation. As with all Chinese ratings that's probably sales jargon.

I've not checked refrigerant charge, I have no kit or experience in doing so.
As it works to an almost acceptable efficiency I decided not to mess.

The GSHP won't be operational until this time next year if all goes to plan, more importantly I now have the stairwell opening cut into the uninsulated and untiled loft letting all my heat out the top of the house.
