    Shed insulation mistake...

    I thought a visqueen vapour barrier was to stop the moisture from being able to get from inside to the insulation cold side? Meaning no condensation. Have I got it wrong?

    Shed insulation mistake...

    Okay thank you, so putting visqueen under the OSB won't make any difference? Extractor fans aren't ideal as I'm heating the space and not the water

    Shed insulation mistake...

    There is no air gap :( if I didn't have an airgap would a vapour barrier have solved the problem? Coraline bitumen sheets Thank you, the tanks have lids so any condensation from them should remain in the tank. Or atleast wouldn't it condensate on the OSB inside?

    How to reduce flow rate?

    All the pipes are lagged, it's a new build. It's like the oil combi boiler can't keep up with the demand. I think it's because the flow rate through the heat exchanger needs to be below 15l per minute to keep the hot water store heated. Would that be right?

    Underfloor heating matt ontop of chipboard

    The only reason i was going down this route was because i had tiles left from building the house. Think i will just cut my losses and get laminate flooring! Seems alot simpler and won't need a ufh matt. Thank you for your help

    Testing new pipe work

    Hi, i have just extended my central heating system to upstairs but before plasterboard i would like to test the system for leaks. If i blank all the tails upstairs and then connect upto the system, will the air in the pipe upstairs bleed from radiators/taps downstairs? Thanks in advance

    Adding new radiators and water / 22mm or 15mm

    Yes it was my decision. Wanted as little space in the house taken up by water cylinders and plumbing pipes.

    Adding new radiators and water / 22mm or 15mm

    Thank you for your reply. So running mostly 22mm for the shower and sink basin won't affect pressure too much? Also is it normal with a combi boiler that if the shower is running and then the kitchen hot tap is opened that the shower goes cold?
