    Personally I wouldn't panic about a vent being present... have a look at the Keylite products too. We went for their UPVC units and they're very impressive, much handier to install than a Velux.

    it's my perception that a perfectly-smooth tile is grippier when wet than the dimpled non-slip things used round municipal swimming pools.

    is PTV carried out wet or dry, and what material is used as the slipper?
  4. dpmiller
    will it run off battery also?

    We're drawn at 16@176r x 250g, 900wide with a 180deg turn halfway. Current temp stair is a single run slightly steeper and no hassle at all so I suspect the 176/250 will be pretty comfy.

    smoke stick / joss stick would do it

    16kW is pretty big for an efficent new build.

    might get away with nothing more than bringing the cistern duct into the main one with an elbow facing downstream.

    not powered by, Ian. Create a low pressure zone in the main extract duct to draw flow from the duct coming from the cistern.

    you could rig up a venturi in the extract duct to draw from the cistern feed.

    these are just the same chinesium edge-lit panels you can get everywhere from B&Q to Ebay. I've just opened a B&Q one I had sitting here which is 5W IIRC and it's 380lm with a 245mA driver.

    nice and flat.

    almost. they set datum tripods and then fill to that level, before dappling the air out and moving any small amounts around to give it the best chance.

    and it's set. hard. Amazing, makes quite the difference to the feel of the house. But then, ten-odd tonnes of mass will do that.

    we were very lucky- the guy we used trained in NZ where architects have a SE portion to their training. he is adept at both the aesthetic and the buildability.

    3800W on a 13A plug?

    if the ductwork is sealed correctly, then your draughty meterbox is unlikely to be caused by the shutter.

    Time for another landmark. Upstairs pipe loop installed, screed poured today as planned. Remarkable stuff- I was expecting runny, but just how coarse the aggregate in it is surprised me.

    what fumes? fumes mean a fault and danger. Are you sure you want to rely on a faulty device as your backup?

    Airtightness just about complete. I'm going to schedule a test for sooner rather than later a that way I can be content before the PB goes on. But in the interim, playing with the settings on the MVHR (one fan at 100%, the other at minimum, no ducts sealed off in any way) I can pull the house from + to - 15Pa. According to the fan charts in the manual that looks like better than 1ACH even with the ducts open? Screed booked to be poured upstairs next Thursday. Much to do before then...

    My experiences exactly, one of the instruments I look after is a faecal occult blood analyser. The wash solution is just a dilute bleach and it's damn-all use for getting fatty residues out of the measuring cuvettes. Q-tip and fairy liquid time...

    This just dropped into my FB newsfeed. A British option on these systems? https://www.sahp.info/

    We didn't do a tray for our dormer, and the only lead we used on the roof was for the chimney back gutters. Everything else we used Leadax for and it's great to work with. Much cheaper than the real thing too.

    CE means China Export, does it not?
