I am in need of a bit of help, I had a new heat only boiler fitted to replace my existing old one and have been left with a bit of a problem and my plumber has become uncontactable.
basically the new system seems to work, the heating comes on when it should and goes off when it should. if I put the water on this clicks on and off nicely with the thermostat on the tank.
The problem is with just the heating on its also heating up the water and as it doesnt know its doing it, it doesnt click off with the boiler thermostat so just keeps on heating up.
any ideas where to start looking?
thanks
