    Plume kit for an old non condensing valiant boiler

    Hi, Does anyone know the part number for a plume kit that is suitable for an old 2006 Vailant ecotec 24 R1 non condensing boiler. I am guessing that the new style are not suitable as they are plastic and will not take the temperature from a non-condensing boiler? Thank you

    Secondary heat exchanger cleaning

    Has anyone tried to clean a partially blocked secondary heat exchanger using system chemicals instead of removing and acid cleaning or replacing it. Got a vokera procombi 85 he which goes cold unless the flow is very low.

    Worcester Greenstar Expansion vessel

    Hi, Serviced a boiler today that was over pressurising when heating up, so thought it would be a simple case of drain down and re-pressurise the vessel. tried that and found that the vessel would not take any pressure as if the valve was blocked, I removed the schrader valve but no change...

    Badly corroded case after leak

    Hi, Just been to repair an Ideal Logic with a water leak, It seems to have been leaking for a long time as the bottom of the case is badly rusted. The leak is caused by a cracked condense sump (common fault). It is the worst corrosion I have seen but it is not rusted through. As the case is...

    Pressure loss through the pipework

    I have recently read a couple of posts on here that specify that the pressure loss from the meter to the applicate can be a max on 1.5 mbar. I always understood it to be 1.0 mbar. Has it changed without my knowledge? I am due to resit my assessment soon so it was a while ago. Mark.

    Multi tool recommendation

    I currently have a blue Bosch corded multitool, but as I am also an electrician I often find myself needing my multitool when I have no power. I currently have the Milwaukee 18v sds, 18v hammer drill and 18v impact driver but the reviews I have read about the Milwaukee multitool don't seem to...

    Central heating problem on Worcester 24i RSF

    Does anyone have experience of these boilers, it has an odd problem where the Hot water works fine and central heating will not light the burner. When a CH demand is given, the pump runs, then fan and it goes no further (no spark or opening of the gas valve) I have tested the CH thermistor and...

    Worcester 24i RSF diverter

    I understand that the 24i RSF boiler does not incorporate a diverter valve, this being the case how does it divert the water to the tap or rads? Mark.

    Worcester Greenstar 30si No hot water

    Hi, I attended this boiler just before Christmas to repair a no hot water situation, symptoms were no response from the boiler when hot water tap was opened. I had a replacement flow switch on the van so I just changed it and all was well. Customer called again a couple of days ago for same...

    Ariston Microgenus 32 HE E34 code

    Hi, Went to look at an Ariston boiler which was cutting out only when hot water was drawn, heating didn't cause the code which is odd. Code relates to APS so I checked for blocked flue, restrictor in flue or recuperator, split tube, venturi blocked, fan fault etc and all were fine, I changed...

    Worcester Greenstar 15 ri blowing internal fuse

    Hi, Attended this yesterday, with the internal fuse blowing as soon as it is switched on. I disconnected ALL the current draws from the PCB and still the fuse blows so it must either be the transformer or the PCB. As the transformer is available as a plug in item I was hoping some one can...

    Ideal Isar 30HE - No Heating

    Hi, I attended a job with no heating but perfect hot water. When heating is selected status goes to 'c' and burner goes solid on for about 20 seconds then goes to flashing. No fault codes. I initially suspected the diverter but oddly the flow pipe from the boiler is roasting and the return...

    Baxi combi 105 HE

    No hot water or Heating, diagnosed that the APS has failed but can see how the old one can Be removed without serious work. The APS fits to a mounting bracket but it is screwed in from the top of the bracket which is nearly touching the top of the case so no chance of getting to the heads. I...

    Hi, Does anyone know where I can get a supply of replacement washers for Type B drain valves? I have asked in all my local merchants and no one has them, they are much smaller than the type A and I seem to be finding a lot that leak.

    Odd problem with an Ariston MicroGenus HE

    Hi, I have been to a customer a couple times, Initially I noticed that it was giving random A01 codes (about every 2 hours), the other thing I noticed was that it was still sparking when lit so the symptoms added up to a rectification issue so I went back and changed the probe and lead but the...

    Hi, Just wondering what others charge for radiator replacements where either a slight alteration is needed or just a straight swap. Also whats your price for adding a new rad where new pipework is required. Just average price as of course every job is different. I charge £100 + materials for...
