Father-in-law has two solar panels on the roof and a DeltaSol BS Plus controller and SolarBloC® midi 3-line station (2 roofs) pumping station in the airing cupboard reading the instructions it says if the water on roof is warmer than water in cistern then water should circulate and the coil is right at the bottom of the cistern so water should be cold and in theory even if it does not heat the water to 60°C at least it should reduce how much gas is used.
However the central heating S plan has a problem, the micro switch in the motorised valve for domestic hot water is stuck on, so the orange wire has been temporary removed to stop the pump running with valves closed, so domestic hot water is only heated when the house central heating calls for heat, however he has no radiator in living room just a gas fire, and if this is left on the central heating will not fire up.
The net result has been no domestic hot water, now I understand maybe not to 60°C but hot water nearly same temperature as cold water.
Before paying out for some one to repair the solar water heating, question is what is it reasonable to expect from a pair of solar panels, at this time of year with only one person in the house what temperature can one expect solar panels to heat the water to?
