Hi , we have a Raven heat boiler ,the water heats up but not the rads , ,Ive replaced a thermo valve , but the heating worked for weeks after that , Ive bled the rads and lots of air came out of them but still no joy AND NOW ITS SNOWING !! can you help please ?
Its a problem with the electronic timer on the front panel even if the red light is on it does not switch over inside so it needs it can be bypassed
on a temp thing as the contacts are volatage free, and just need looping together, get a corgi man to do a temporary link so at least you will have the heating working
you do not say which model it is by the way but the all use the same digital clock
i have replaced dozens
the diverter valve sit on the heating in an open position and the port is only closed on a call for hot water
