Hi, we have a Worcester 24i RSF-L combi with an intermittent problem. Sometimes it just doesn't work, no hot water or heating. A CH engineer came out and eventually changed the fan at the top after he removed the long clear pipe coming from the fan, blew down it and the boiler started up. He...

Hello all, first post here so be gentle with me! I am the (not so) proud owner of an archaic WORCESTER 28CDI combi. Around Xmas time the boiler made some horrible loud grinding noises and then gave up completely, RGI came round and diagnosed the fan. Brand new fan fitted and then the boiler...

Got a quote recently for a new Worcester boiler to replace a 10 year old Potterton boiler which is 15kw. Never had any problems with the 15kw Potterton in terms of power. The installer says it's worth paying a little extra for the 18kw because it will be more efficient - something about the...

We have a Worcester Bosch Danesmoor 20/25 oil boiler that's quite old but has been OK for the 6 years we have lived here. It has on occasion gone into idle mode which I have sorted by pressing the solenoid. However when I tried to turn on the heating a few weeks ago it just locked out after a...
