Water was dripping from the underside of the boiler, so we got a plumber to take a look.
He said the heat exchanger was cracked and that it would be a big and costly job to replace. The part is not available off the shelf and would need to be ordered and will take a few days to arrive. Quoted at least £500 to repair and replace.
Worst thing is, because the water is leaking near the circuit board, he said we can't use the boiler. I asked if there was something that could be done temporarily, to stem the leak until it can be fixed, but apparently not!
So now the weather is freezing again, and we have no hot water or central heating.
We are considering getting a new boiler, but hate being forced into a rush decision. The heating guy said he could fit it one evening, but the main thing that concerns me is that he is not gas safe registered. He told us that a new boiler will come with a warranty, but surely there are certain conditions around how the installation needs to be done for the warranty to be valid?
Current boiler is around 6 years old, a Worcester Bosch. It still actually works and is not losing pressure, just has this leak which is worse when switched off. would you still use it while deciding what to do?
Would like a second opinion but can't get someone else out until Monday!
