I’ve bought a refurbished one of these, for £550 to install in my father’s house.
It’s mostly vacant at the moment and connected to a 40 year old oil boiler that was burning thousands per year until I switched it off. As this house is in Germany an install by a plumber would cost about £30000, minus 70% grant, so still close to £10000. As this seems crazy and not worth it, I’ve devised this KISS system:
Refurbished Heatpump £550
Bits from bes.co.uk (1 anti freeze valve, magnetic filter, y-strainer, expansion vessel, insulator, air vent, ball valves, flex hoses, pipe insulation): £350
Pipes etc I forgot: £200
So I should get by with not far past £1000. Am I missing something? Anybody got experience with this cheap as chips model? Hot water is supplied by an electric instantaneous heater. Thanks.
