Is it possible to use the heat in a conservatory to heat domestic hot water?

[Phil]

Good evenings,

I had call from a neighbour of mine wanting to know is he could harness the heat energy built up in his conservatory and use it to heat his domestic hot water.
Is there some kind of heat exchanger system available?
I am going round tomorrow to see him in the morning, I just wondered is anyone had come across such a device.
Thanks for any advice.

Hi Phil,

Not that i know off after 30 years in this game, you can get heat from below ground outside but just remember conservatories are pretty cold in the winter months.

Strange Kes 36, he sounded pretty sure such an item exists but if you've never heard of one in 30 years then.........??

I was speaking to a guy in Plumb Centre and he's heard of people using a radiator - painting it black, positioning it in direct sunlight and connecting it to the HWSC with a small pump. Does this sound do- able?. He said it is quite effective.

Hi phil,

So painting a radiator black in direct sunlight, connecting this to the hot water cylinder via a pump. This sounds like a way to breed legionaires to me.
Surely this could only be effective in the summer months?
Personnally i wouldnt do it.

Take care mate.
