within the last week i have treated my boiler with a limescale remover i inteneded leaving it in the system for four weeks as per manufacturers recomendations, however my radiators are no longer getting hot just getting warm (the hot water works fine) when the boiler is running in central heating mode the boiler only stays on a few minutes before cutting out then after about 5 mins it starts up again can anyone help
Are you sure there is at least one rad with no thermostat..(or check your lockshields on the 'open rad' are actually open and not been closed) .
I know it sounds obvious but if the circuit ends up totally closed (thermostats click in on all rads) , the boiler will shut off due to build of of pressure .....
