    Burner lock out on heating only?

    I know that this makes no sense, but I have a boiler burner that only locks out when the heating is on. I know that the burner only receives power to make it fire and has now idea whether it's from hot water or heating but that is what's happening. Any ideas?

    What size compressor?

    Anybody used a smaller than 24 Litre Compressor to blow out Oil Lines? Ive seen some 4.5 L to 12 L ones and was wondering if there would be enough sustained air to shift water and sludge.

    Reverse Circulation.

    I am the local heating engineer, I was asking around to make sure that I haven't missed a trick. I did the temp checks to prove that the 3 port valve wasn't at fault and to prove which way the water was travelling i.e finding the easiest route which was back up the radiator return and not back...

    Reverse Circulation.

    The expansion vessel was a like-for-like replacement on the boiler.

    Reverse Circulation.

    I have clamped a temperature sensor on the heating outlet of the 3 port valve and another on the return from the radiators, the heated water is definately travelling back up the heating return also the the return pipe on the rads is heating up first. When the programmer is switched to heating...

    Reverse Circulation.

    The upstairs radiators are getting warm when programmer is on hot water only. This has only recently started to happen, I don't think that it's the 3 port valve as the flow outlet to the heating is cold. Surely it's not a piping issue as it's only just started to happen. Any ideas?

    Delayed pump overrun.

    It's an old Glow Worm 40BR Mk 2. Would there be a 'stat to control the overrun? It seams that once the water boils the pump cuts in.

    Delayed pump overrun.

    Any ideas why there would be a delay in my pump overrun. the delay is about 5 seconds and causes residual heat in the boiler to boil the water which results in loud knocking.

    Pump over run delay.

    We've got an old Glow Worm 40 BR Mk 2 boiler, when both stats stop calling for heat the boiler & pump stop together then after a few seconds the pump goes into overrun mode, which is to late as the residual heat in exchanger has boiled the water and caused horrific banging. Is there an overrun...

    banging air?

    It's a fully pumped system, with pump overrun.

    banging air?

    When our heating switches off we get a very loud banging noise from our system. It only happens on the heating. The pump is installed so that it pumps down, is it possible that air produced by cavitation by the pump is released when it stops and causes the noise.
