Can solar thermal in the UK provide central heating or is it restricted to hot water supplementing?
Space heating from solar is far more complex (than heating hot water) since it requires integration with your radiator / under floor heating system, rather than just the hot water tank. It IS possible, but not something Solarcentury specialise in. The most efficient thermal systems are evacuated tubes, but they are also the most costly and a decent flat plate collector will still work very well in most situations and provide a more cost effective solution.
