[QUOTE="Jean de Florette, post: 529176, member: 35097"] Thanks binky I see your point about the winter sun factor limitations, but a system that uses solar thermal as well looks like a good idea until I get to the bit where evacuated tube arrays are so efficient that come summer I have to use a heat dump! The idea of having to use an air blast cooler in order to take-out excess heating leaves me wondering if it would be such a good idea? According to what I have read, evacuated tubes give the best thermal efficiency - summer/winter, but can be damaged when excess heat is not diverted to a heat dump. This is the reason why I havn't gone down the route of a total solar thermal array. [/QUOTE]
