Hello, I am look some advice. Our boiler heats the water for the radiators, but the hot water only makes it as far as this component ( pump is above it). It has a temperature sensor in it reading air temperature in the void, but I think it must have a cross over in it from the central heating return I think as the pump runs but just seems to circulate the water at circa 25degC, not adding in the water from the boiler that is around 80C. Ci don’t understand how it’s workings at present so not sure where to start trying to sort it. Any advice greatly received.
Thanks
Phil
