Hi all,
My boiler is a Worcester 28i Junior and the fan switches itself on for no reason.
The timer will be off and the hating may have been off for several hours but it does this intermittently throughout the day and night. We have noticed that our electricity bills are higher than normal and suspect that this may be the cause. The boiler is not firing up just the fan switching on. It turns on for approx. 90 seconds every 5 minutes. Any ideas? It has a drayton wiser smart thermostat connected to it.
