Grant Vortex 26e no hot water
Grant Vortex 26e no hot water
Runs for eight mins or so from cold, but can't feel any heat to heat exchanger, then overheat cuts in and boiler starts making rude noises until it cools. Pipes at top are hot. Pump? I've seen a non return valve mentioned, but where is it and how do you test, or is it in the pump?
Heating works, but has its own pump.
TIA
