    Leaking HW Cylinder Flange

    Did one recently. Drain cylinder and central heating. Dismantle pipework and flange - cylinder coil will sway about when loose. Clean all threads. Make a washer out of ptfe and paste it up. Reassemble and don't over tighten. Fill back up and give an extra nip if required. Worked fine for me...

    High pitched whine that rises and falls for hours after central heating has been on

    If you think this is a CH issue then you should be able to repeat it during normal hours. Or the noise may be there all the time and you're just not noticing it during the day as it's not as quiet and maybe you're not in the bedroom! Note that water supply pressures tend to rise during the...

    Under mount sink cradle

    Totally agree mate. I use "form over function" We did it in our kitchen years ago... 2 x round undernounted sinks. Soon got rid of them when we had kids... Double bowl and drainer and it still gets piled high with crap!

    Combi boiler is on when no heating or hot water is being used

    They're not when installed by someone who knows what they're doing! Developers won't have a heating engineer on the books and don't want to incurr costs getting one in!

    You mean pressure gauge? That should be around 1.2 when system cold. It needs looking at tbh.

    Ideal Logic Pump Overrun

    Baxi Main Heat only don't need pump overrun. Determined that the hex cools enough on its own, I presume?

    Bypass valve

    Not good to have pumps in series. Better to have an LLH, plate or CCTs.

    +1. Have you confirmed this by asking them to switch it off to test?

    Combi boiler is on when no heating or hot water is being used

    It's very common for this to be overlooked. I did it a couple of times when I started but soon learned to always remove the link when wiring in external controls. Most combis come with this link connected, out of the factory.

    Heat Loss - Pen & Paper Check

    Heat loss is heat loss. Low temp heating will be enforced one way or another. Physics and regulations care not how old your walls are ;) At the end of the day, it's your decision but if BC are involved, they won't have it. Otherwise, crack on. (y)
