Re: Chromagen solar hot water
Heat pump system? = Reverse cycle air con but rather than use compressing the gas to release energy (heat) inside your house with a condensor/radiator thing plus a fan - the radiator is instead in a hot water cylinder. So heat goes in to water and cold-er air is blown out of the compressor unit on top (could be great in warmer areas to help cool your house but not so good in colder parts as they rely on ambient air temp - not like traditional tubes and panels that use the sun's radiant energy).
If you want to know about problems with anything try searching "chromagen + problems + defects or + leaking" - like schools and hotels and everything else on the net if someone has had a problem with anything they will tell the world on a blog or some such.
