    Advice? -Ferroli 701 heating turning off/on?

    PTC thermistors were not unusual for boilers developed in the 90s when boiler control was less advanced. Some models had PTCs that had resistances down to a few ohms. What's the pump like?

    New radiator now boiler doesn't work (Ariston Microgenus 23 MFFI)

    The boiler might be full of trapped air. Run the heating and open the hot tap every minute or so. Keep reseting it and with luck it might solve the problem.

    Is This Legal?

    IMHO The water regs are a statutory document ie. it's the law! https://www.legislation.gov.uk/uksi/1999/1148/regulation/4/made And to demonstrate a "workmanship" installation (reg 4 part 5/6) the installer should show compliance with standards such as... BS 6700:2006 Design, installation...

    Looks like efflorescence...try brushing it off and with time as the wall drys the salts may stop coming to the surface.

    At risk notice: "Gas pipe not using correct entry/exit point of meter box"

    We can't tell how butchered that box is...it could have a gaping hole into the cavity. If they're prepared to bodge that much then taking a lump hammer to the box won't worry them

    At risk notice: "Gas pipe not using correct entry/exit point of meter box"

    Gas leaks on/around gas meters are common and the issue is whether they can find their way into the wall cavity and property. Without seeing exactly how the pipe exits the box we can't say for certain what course of action should be taken. Either way it's a bodge job. Best option would be to...

    Potterson Boiler - Circulation pump

    If it's in a Puma etc the back casing threads are not compatible with standard pumps AFAIR. Take a look on ebay...there's a few new Myson CP53 pumps on there at silly prices..just swap the head over.

    Worcester Bosch 6 Bar PRV Replacemenet

    Ok so it's got nothing to do with the Greenstar CDi boiler.... You need to get a G3 licenced plumber to sort out your unvented cylinder. As well as ther safety valve the expansion vessels probably flat/failed and given the rough installation don't be surprised if there's a few other things that...

    My incoming water main

    Get yourself another heating "engineer", only by measuring static/dynamic water pressures and flow rates can you determine whether the incoming service pipework is sufficient. My own place has an imperial copper 1/2 main but with 5 bar static the flowrate is ample at say 1 bar dynamic (the...

    Worcester Greenstar 432kHz noise?. SOLVED. Honeywell Gas Control Valve, faulty batch.

    The ratio is pretty meaningless...it's the ratio between carbon monoxide and carbon dioxide. The figure is "designed" to show how safe the combustion is but the relevant figures we need are the carbon dioxide at the high and low combustion settings. Given the boiler is so new a proper annual...

    Worcester Greenstar

    The component count has massively reduced as electronics manufacturer have brought out purpose designed driver chips. Boiler manufacturers charge what they can get away with...plenty of other Worcester parts are now extortionate.
