hi, we have a worcester heatslave 15- 19 oil boiler which has started to play up , the central heating has come on permantly and we have no hot water!! the only way we can turn the ch off is by turning off the power.. has anybody any ideas ??? thanks
As it's HW priority it may have a faulty or sticking diverter valve. The HW store will not reach temp thus store stat will keep calling for heat which is moving down CH channel.
Agreed - diverter valve for sure, especially if the rads start to melt when you turn the hot water stat up.
You may get away with a new top to the valve, called the powerhead.
