If so, I'd value some advice please.
I have a Worcester Bosch Greenstar 30 DCi Conventional boiler installed in my kitchen. There's a hot water tank in the airing cupboard upstairs, a programable timer in the kitchen and a thermostat in the hall (both Danfoss units).
Over recent months, with increasing frequency, the boiler won't shut off at the end of a programme. Instead it keeps firing up for a few minutes, then shutting off, only to fire up again. This cycle repeats until I lower the output dial from about 5 (the recommended level) to about 1 or 2. Sometimes I have to switch the boiler off in order to stop it. This is becoming the most regular 'fix'. The programmer can be off, the thermostat can be down low and yet the boiler just keeps on firing up.
I've spoken to the company that service it - no ideas from them. I've spoken to Worcester Bosch - again, no ideas, and I've also spoken to a couple of local heating engineers who again are baffled. No-one has been out to do an inspection on it yet, in part because the problem is very intermittent. The boiler is serviced annually and is about 4 years old, although I didn't have it installed - this was done by the previous house owner.
If anyone has any experience of this or any ideas, I would be very, very grateful. Thanks for reading
