Solar water heating (SWH) systems are a mature renewable energy technology which have been accepted in most countries for many years. SWH has been widely used in Israel, Australia, Japan, Austria and China.
a heater that makes direct use of solar energy
Divide to leave a central space
(part) something determined in relation to something that includes it; "he wanted to feel a part of something bigger than himself"; "I read a portion of the manuscript"; "the smaller component is hard to reach"; "the animal constituent of plankton"
Cause to divide or move apart, leaving a central space
(part) separate: go one's own way; move apart; "The friends separated after the party"
the local environment; "he hasn't been seen around these parts in years"
(of two things) Move away from each other
working on solar water heater
we painted hose black to better absorb the solar energy. wood on top and bottom make the tin rigid and easier to move. underneath there is additional cross pieces at either end. you can see a part of these cross pieces extending out at the top right corner. four of these create handles for carrying the heater. hose coils into centre, goes in low depression to centre of other coil and spirals out. a valve at either end than controls flow and allows this to be disconnected for service or moving.
Solar Hot Water Heater
Actually, there are a few minor details still to be completed, like insulating the hot water tank. And there are always more projects, like our newest plan: to build the lower part of the tower into a chicken coop so that we can raise chickens for fresh eggs!
