Central Heating and Water on continuously?
New CH pump fitted a month ago by a registered plumber. Since then the Central heating and water runs continuously. The Programmer and the Thermostat make no difference to the operation ( they can be OFF and turned right down respectively ) and the boiler is still alight and the pump runs continuosly 24 hours.
So rads are HOT and hot water is HOT. Had a quick look at the jumble of electrical wires where everything meets, including the new CH Pump, and its spaghetti.
My feeling is that in wiring the pump the plumber ( Ha! ) has incorrectly connected it and or disturbed wires. This means that the pump and boiler operation is always powered and not controlled by the Programmer.
Any ideas please.
