Have a Worcester-bosh greenstar ri boiler. Its been turned off for a few days and now its expected to come on again, it decides only to fire up for half a minute at a time every four or five minutes.
Rolling up my sleeves for a bit of D-i-y I confidently get out the instruction manuel, and the ego takes a knock as i realise just how much out of my depth I am.
It's in north london and although cold its not been freezing. Is there any simple things that i could try doing?
If I call out an expert is it worth paying a lot extra for the Bosh man to come out? Or is it something my local gas qualified chap could reasonable take on? Grateful for advice please, we are already feeling the cold.
