i have a good working thorn emi free standing boiler.sudenly got hot water but radiaters are not getting warm..boiler fires up but too soon goes off can you please help
you have a motorised valve on your heating circuit that has stuck closed,if this has happened the vavle stays shut and will not allow hot water from the boiler to circulate to the rads. do you have a time clock for rads and hot water only?
