    Waste pipes above ceiling in new extension

    Hi guys I have expressed an opinion on this waste plumbing which is by a builder on an extension to a terraced house belonging to a relative. My opinion has not been received well so what do we think? The new black pipes will soon disappear under a pitched roof brought across from the left. The...

    Safest to try this after turning off the water in the street to avoid a possible soaking.

    Hot black water coming out of bath tap in newly refurbished. Bathroom

    No need for 22mm pipe in an unvented system. Just increases dead space losses.

    Backer / Cement board for low level UFH

    I lusted after underfloor heating for years. If I'd done it just 5 years ago my system would have been incompatible with 2023 current standards and very disruptive to install. I then discovered large 2-2 radiators can be sited unobtrusively and perform brilliantly!

    Snapped screws on heat exchanger require a whole replacement?

    Youve done well to keep this boiler for so long. Search Youtube for "Do Not Repair Ideal ISAR and ICOS Boilers"

    Can I connect my washing machine waste pipe to this standing pipe?

    Yes make new downpipe as long as possible. I'd convert to pushfit after a new compression Tee so any blockages could be cleared.

    Can I connect my washing machine waste pipe to this standing pipe?

    Yes. But you’ll need a U bend at the bottom to isolate any smells.

    Can I connect my washing machine waste pipe to this standing pipe?

    Put a new downpipe parallel to that one and Tee it in near the bottom.

    I need advice on a replacement for my Honeywell C21 Programmer, please

    You should also have red sleeving on that yellow fire cable to conform with regs. If you move it as I stated it should work. No need to thank me.

    I need advice on a replacement for my Honeywell C21 Programmer, please

    Got it now the fire line is yellow thought it was an earth. Terminal L has to be jump connected to terminal 1 with an additional short cable. Yellow fire line has to be moved from terminal 4 to terminal 3. But 240V so make sure you feel competent to do it.

    I need advice on a replacement for my Honeywell C21 Programmer, please

    Is your boiler fitted with an optional controller with time settings, and these are the settings you use to control times? If so your old controller was doing nothing.

    Radiator is heating up only to 1/3 of high

    The reseller ignores UK regulations about efficiency information. So why would they produce a decent manual?

    I need advice on a replacement for my Honeywell C21 Programmer, please

    The feed to your boiler is connected straight onto the power supply, your old programmer was doing nothing and the boiler was permanently powered up. It sounds like the new programmer is working fine but has no conductor to the boiler to fire it up. The back box needs a wiring modification so...

    Radiator is heating up only to 1/3 of high

    This radiator doesn’t put out a great deal of heat and the Amazon description of its heat output makes it seem better than it is.

    Radiator is heating up only to 1/3 of high

    You might the look of that, but it has no fins. The claimed output is 6557 BTU but at T60. A mean radiator temp of 80 degrees is crazy hot. Installed on a new system, designed to regs for flow of 55deg return of 35deg, this radiator would put out 2255BTU, or .66 kW. B2-EN442 states all...

    Unvented Cylinder Single coil heat pump vs twin coil solar

    If your boiler delivers 24KW of heat to coils with a 50kW capacity, the hot water still only receives 24KW of energy and so heats up at the same rate.
