Solar water heating (tubes)

Farrgar

Hi Folks,

Has any one got theses tubes installed? I'm wondering if they will be able to run 6-7 radiators as well as keeping the water hot.
Any input is welcome.

Regards

On a domestic system, it is not practical and would have a very long, if ever, payback. Simply put, when the sun is shining, and it is nice and warm, there will be usable heat, via a buffer tank/heat exchanger set-up. And when its cold and dull outside(ie, when you want heat), there is maybe only a little contributation to the hot water, but none towards the heating system.

It can be done , and it can work , just not in your average bog standard house.

You would need a huge buffer tank , a house which is passiv haus standard or better i would say. And a large roof full of tubes.

Personally what works well is.

Large buffer tank connected to possibly a wood gasification boiler . Then have tubes on the roof which contribute to the hot water cylinder primarily, and if the cylinder is satisfied , leave it contribute to the buffer.

But realistically speaking I would be better off going with a different system?

Any ideas?

Yep im full of ideas , as are others but will need some info first.

What sort of house is it ? 3bed semi ? small cottage ?
New build or renovation?

Are you on a tight budget ?
Do you have any personal preferences ? gas/oil/wood etc?

Thermodynamic Solar Panel and system perhaps?

Can be used with alloy rads to heat a house.
