my saunier duval 30e system wont heat the radiators?
the boiler was left switched off while the property has been vacant, i have new tenants moving in and have tried the boiler, the pressure has been re-set and the hot water works, but the indicator light on the central heating isnt illuminated and despite bleeding the radiatiors there is still nothing going through the central heating system. any ideas please?
