Despite the rainy weather, I have now completed the soldering of the tubes for the solar collector. I connected it temporarily to the Horse Field water supply pressure vessel with a hosepipe, in order to test for leaks. I don’t want to install it on the roof and then find it’s dripping! The Horse Field tank holds some 300 litres of water at 4 bars pressure, so this is four times the pressure required by the solar collector when in operation. (When installed, the solar collector will contain propylene glycol at a mere 1 bar, as it will be an open vented system). I was pleased to find there were no leaks, so it would appear my joint soldering was up to scratch.<\/p>\n
The pipework was then fixed to the backing plate by using lengths of copper wire salvaged from the old electric wiring I ripped out when I upgraded the household electricity. I then fixed the temperature sensor in place using thermal glue. Once that was done, I painted the pipes matt black. After giving it another coat of paint tomorrow I can then start putting it all together.<\/p>\n
In the late afternoon we bought yet another two hens; that makes a total of eight. Well, we have the room. Of course putting the new occupants to bed was interesting; they’d never seen a perch before!<\/p>\n
Unfortunately this means the hens’ profit and loss account is in the red again, but I calculate we only need another 35 eggs to reach the new break-even point.<\/p>\n","protected":false},"excerpt":{"rendered":"
