Hi everyone, I have moved into a new house, there is a mini c32 combi upstairs with radiators in each bedroom, downstairs there is underfloor heating with a thermostat also downstairs.
Unfortunatley there is no one to ask how it is setup I know how a combi works, but the underfloor heating has been switched off, does anyone know how the setup should be, I think the Ch has to be on to provide hotwater downstairs for the underfloor heating, the thermostat attached to the underloor heating is set to 5 and this gets warm when the seperate thermo is turned to 25ish....Its just confusing for me to see how it al works together efficientley, can anyone please help.
