My boiler, a Vokera combi, has finally stopped working after 14 years. The hot water will only come in if the heating is switched on first and British Gas have not fixed it. It always works when they are there and stops working again after it has been cold a couple of hours. So I want to get a new boiler. Does anyone have any suggestions? I have been recommended a Vaillant 824 Eco. I have a small one bedroomed flat on the second floor with a flue that goes up through the ceiling, presumably to the loft and then out. I run a shower straight from the boiler. I would appreciate any suggestions. I have heard that the new compulsory condensing boilers go wrong alot, the British Gas engineers who frequent my house, always tell me this! But I realise I have to have one.
