i have a potterton prima 60f, my room thermostat keeps blowing the fuse on the honeywell contol, so no not water, the hot water works fine

if the fuse keeps blowing water is touching the heating electrics and it means you need to replace the heating pump. Im assuming that no one has done any alterations to the heating electrics or has possibly nailed or screwed a cable, if not then you need a new central heating pump
