I DID NOT CAUSE THE EXLOSIONS! These boilers are crap. Any work has been carried out by so-called "registered engineers".

An update after visit from British Gas Boiler Engineer - The boiler does not fire because the combustion/depression chamber cover does not sit absolutely tight. Screws/Threads are not tight. The resolution might be a new boiler. because it is not economical to take the boiler off the...

I agree. I have Npower visiting this week. You should always get a registered engineer to look at any problems with Gas etc. Which is exactly what I have been doing. But despite that - Ravenheat boilers tend to run for a short period and break down. You should also be fully informed of...

OK... Just an update... last week the 'build up of gas' led to a minor internal explosion. I think it has knocked out the air pressure switch. I have ordered an APS and Fan Control Board. Blowing into the venturi tube (from flue) lights the boiler - therefore it must be either APS or...

Seems logical. Its a manufacturing defect then if its common?? Is there a resolution for the problem as yet? Or is it a case of 'living with it' or getting a new boiler?

No air in the system anymore. The only problem is occasional internal noise (loud bang). I will not be doing any gas work myself! Just trying to understand the problem. I have already been quoted £80 call out charge + £30 for the first 15 minutes of evaluation! Will definetly get a...

Lound banging is still occurs occastionally. Metal casing surrounding burner etc is bulging because of this! Loud bang = noisy ignition How do you alter the burner pressures and set correctly?

OK.. Found the cause. There was no water feeding back into the boiler. A stop valve was closed. Didn't notice! Simple!?

There is no external room stat. All controls are on the boiler. There are two dial settings. One for hot water HW, and another for HW + CH. Water Setting is at above medium (at the highest effeciency line) for both. All wires seem to be in tact around the timer (On board). The central...

I have an adopted Ravenheat Boiler HE 85AT unfortunetly! Central Heating is not coming on, although the hot water is working. Any ideas anyone? The Air pressure switch (at the top) is fine. I have blown through the preceding pipe and it is switching. The fan comes on OK when the hot water...
