    Plaster/mortar cracking along joint of extended property

    Hi We live in a 1950's semi which had a single storey extension to the ground floor in 1984. The extension extended two rooms (lounge and kitchen, so a party wall, internal wall and external wall). Recently we noticed a crack in the plaster of the party wall which we hadn't seen before...

    HW very hot, no CH, boiler firing randomly - no idea!

    Took the motor out and the spindle moves freely. To do this I obviously cut the power to the valve, pump, boiler and immersion in the loft as well as the programmer which is downstairs with the boiler. When I switched everything back on, I turned the hot water on (on its own) at the...

    ACL Lifestyle 679H340-30l0 mid position valve woes!

    Update: I dug out the wiring diagrams for the system and after taking an hour or so to have a good look over the wiring at the junction box and the programmer. Everything seemed to be in place (a couple of bits that I wasn't sure about), so I didn't change anything. The girlfriend was...

    ACL Lifestyle 679H340-30l0 mid position valve woes!

    The cylinder stat goes from 50C to 90C (from memory) - I definitely turned it up, which caused the pump to kick in.

    ACL Lifestyle 679H340-30l0 mid position valve woes!

    Thanks everyone for your input. In response to D_Hailsham - The boiler was set to 50C this morning before I turned the hot water on. Once I had turned the HW on (with the heating remaining off) I went back into the loft and turned up the cylinder stat, at which point the pump fired up...

    ACL Lifestyle 679H340-30l0 mid position valve woes!

    Update.... Last night I turned the immersion heater off and by the time we went to bed all of the remaining hot water had gone (taps running cold). I set the HW to come on this morning whilst the heating was off (which it didn't despite the timings and clock being correct?) When I got up...

    ACL Lifestyle 679H340-30l0 mid position valve woes!

    Hi all We moved into a house in the summer and noticed from the get-go that our hot water was scalding hot. I tried turning the thermostat on the cylinder down but it made no difference whatsoever. I've recently discovered that this is due to an immersion heater that appears to have been...

    External bathroom wall insulation

    Thanks so much for the quick reply! Because space is an issue we're thinking of making a 40mm deep stud and using 25mm Celotex board. Would it be worth filling the remaining space with another form of insulation? We've chosen Marmox boards because they're "waterproof" and have inbuilt...

    External bathroom wall insulation

    Hi We have a west-facing bathroom wall which we have taken back to brick. We're confused about the best way to insulate the wall and reduce the risk of damp from the inside (or outside!). The current plan is to build a stud wall (studs at 300mm intervals), fit Celotex in between the studs...
