Hi all,
I have an odd problem with my boiler that I am not sure how to resolve.
I have a Worcester Bosch boiler, a CDI 40 Conventional.
The boiler provides central heating (control by a thermostat in the house) and hot water. Both are also controlled by a timer system.
The house has two hot water cylinders. These have a solar heating element on a separate system that is set to a maximum temperature of 65 deg C. They also have heating elements from the boiler.
I noticed today that the boiler seems to be constantly cycling. With the central heating and hot water off (set to off with the control timer), the boiler shows a temperature of 65 degrees C and this slowly drops to 60 degrees C. When it hits 60 the boiler kicks in until the temperature is back up to 65 and water can be hear moving about the system. This cycle of heating and cooling continues every few mins.
Resetting the boiler does not change the behaviour, not does turning on the ECO mode (which I thought stopped the boiler keeping hot water ready to go).
I do not know much about boilers, but this behaviour seems to be rather odd, and I would expect the boiler to sit dormant until either the central is triggered (via the themostat / timer) or until the water is triggered (via the timer or turning on a hot tap).
Do I have an issue and is the system wasting gas????
Thanks
below are some snaps of the system. Note it says 58 degrees as the Mrs had a fiddle and turned the dial on the unit down a little..
