Hot water solar panels losing pressure

    Hi,

    We have solar panels for our hot water and system pressure dropped to 0 recently, got a plumber out last Wednesday who fixed a leak and refilled the system pressure to 2 bar. Over the weekend I've noticed that the system pressure has fallen back to just above 1 bar, could this be due to the cold weather or is it likely to be another leak or some other issue?

    Hard to say, keep an eye on it. If it falls down further significantly, it's probably another leak. I presume the plumber bled the system so there weren't any air locks left and the system was filled up properly.

    Had similar when the diaphragm on the pressure vessel failed. Would pressurise and seem ok for a short while and then start hearing air in the pump

    It seems to have stabilised at around 1.2 bar of pressure, hasn't moved from there in the last 48 hours. I'll keep an eye on it for the time being in case it starts dropping again.
