After doing loads of research I think I have a SMC twin pump central heating system (after searching high and low for a diverter valve) but I can't work out why my radiators don't work properly.
If the heating is turned on, on the control panel, the boiler (Potterton Netaheat) fires up when lounge thermostat is turned up, as it should, but the radiators don't get hot.
The only way i can get the heating to work is by turning the thermostat on the hot water tank up high and this seems to make water pump around the whole system regardless of whether the switch is turned to h/w on or both h/w & c/h.
Why should this happen?? I'm pretty sure i can hear both pumps running in garage so I don't think its the heating pump (I may be wrong though)
By the way I have recently moved into this house (my first!!!) so don't have any experience with this system or heating in general.
Any help would be greatly appreciated (My better half is starting to complain of the cold!!!)
Thanks in advance
