Evacuated tube for heating domestic water with solar energy.

Hi. Since this is your first question (sort of) I'll make a stab. Evacuated usually means a vacuum and is used to insulate. A tube within a tube could deliver hot water to a tank with minimum heat loss.

Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Each evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating (Al-N/Al) which features excellent solar radiation absorption and minimal reflection properties. The top of the two tubes are fused together and the air contained in the space between the two layers of glass is pumped out while exposing the tube to high temperatures.more info ,you can browse the website www.himinsun.com

Very good choice, higher temp, low loss hard to seal but worth it.
With the above features smaller panel, good for focusing collector, now all you have to do is build it, I always thought the evacuated tube at the focus of an involute curve would be ideal, read up on the involute curve and you'll see a tracking collector that has few if any moving parts... Good luck

I don't see what the advantage of an evacuated tube. This would need a pump (energy) to create and another pump (energy) to get the water out again.

Hi friend, the solar evacuated tube are the key component of the solar water heaters, it absorbs the sunshine and make the cold water to hot water, and so supply you a comfortable bathing, now we have a new small pump which are installed at the end of the water flower, the solar water heater will be your best choice now for bathing in the winter.
