[QUOTE="Exfarmer, post: 7709041, member: 1951"] Are you looking to go off grid? If so there is no way you can power something like a heat pump unless you have a solid renewable source such as Hydro. Or a very big battery The huge problem of heat pumps, is they only work efficiently when the weather is right. Yes they can work when the temperature is well below freezing but they are very poor when the temperature is in the range 0 - + 10c and the humidity is high. Which is about average in the UK from mid October to March. This is unlucky since the this is when our demand is highest. The quoted average of 3 X the heat recovered for energy input is an average of the best performance in warm weather of 7 to 1 and the poorest in winter weather of just 1 to 1. I have runa heat pump for 15 years and now what I am talking about. I also have 8 kw of panels on my house, which do not produce a lot when I need it most. Domestic heat pumps combine an immersion element to avoid the repetitive re cycling that is needed when they would be in de frost mode . This makes a complete mockery of the concept in my opinion and of claims of their efficiency. I use a gas boiler for my house which is far more efficient in energy delivery. [/QUOTE]
