There’s more than enough installed to prove that they can and do work, when properly installed of course. Regarding solar installation costs, are you referring to the installation labour costs excluding the panel cost, or the total cost? The price of panels has plummeted, so it is no surprise that the total cost has dropped markedly. I would not be surprised also if labour costs dropped, with lower profit margins. As I said earlier, I’m not convinced subsidies were a good idea, tax money from us all went to wealthy middle and upper class people, and the market would have taken off anyway when panels became cheap. Some of my financially well off neighbours receive huge FIT payments each year.
I’ve been getting more quotes, only Heat Geek want payment for a survey, namely £250. The others are free. There is a range in prices, from £500 to £6,155 with heat pump power ranging from 4 kW to 8 kW. Of course these are price estimates, a survey is needed to provide a firm price and specification. The cheapest is Adlår who operate in Holland, Sweden and elsewhere in Europe and install their own brand of heat pump. I am more inclined to a known brand such as Worcester Bosch and Vaillant. They claim that the 15 mm radiator piping will be fine. I have never had to turn my system right up, and keep many radiators on a low flow rate. -5 C is the lowest thus far in 15 years. I still don’t know enough e.g. does heat pump power matter beyond a minimum necessary.
Almost none of these companies have stellar Trust Pilot reviews, one in ten very unhappy customers is not great. That said, they don’t seem to be because systems don’t work, but because they’re not explaining the system operation, or not fixing installation issues quickly.
I have a woodburner stove, installed to allow for my gas boiler going down in winter. 15 years later and not one down period.
