    That's interesting. As well as your UFH? Do you have any pictures you'd be willing to share?
  2. AartWessels
    Ohh, that's interesting, but I won't hijack this topic, thanks for the feedback 🙂
  3. AartWessels
    Well, that's basically what I mean, my apologies, English is not my first language. I was curious about the way is has been sealed.
  4. AartWessels
    Just out of curiosity, how did you 'sleeve' any of the ducting through the insulation?
  5. AartWessels
    I've moved the web app to https://heatloss.online/ That should take care of the warning message I hope?
  6. AartWessels
    Hmm probably because I didn't add a certificate. Thanks for letting me know, will add one.

    Something I haven't mentioned and is maybe not obvious, is that you'll have to drag the pin to the right location. It uses the 20 year temperatures in the location for the calculations, and NE Scotland might be a bit different from where you are? Anyway, I'll look into it, because there may very well be flaws in some formulas. However, the impact of the COP should normally be visible in the graph immediately when you change the value.
  8. AartWessels
    @IanR Very helpful, thank you. Once I find a bit of time, I'll try to improve some of those 🙂 It does take the COP into account, but I'll recheck the calculations. It just assumes heating to compensate the heat loss, to ensure the expected temperature. What it doesn't take into account in for example solar gains, etc.

    Love the spreadsheet! Love it so much, that it inspired me to try and build something similar in an interactive web app. Still early days in development, and definitely not finished, but feel free to play around, and see if it helps you. http://pdmove-001-site2.jtempurl.com/

    We've only.moved to Scotland from the continent 2 years ago. Our worst power cut until now was 26 hours. Apart from a paraffin heater, we have no alternative source of heat in the current house. For the new build, we'll have battery backup, as well as a wood burning stove. As for stoves: There is a legal right to cut and burn peat for heating your house for crofters, as part of the crofting act. So in the short term, there will be no legal ban on stoves. At least not in the crofting counties.
  11. AartWessels
    True. However, I'm sure you've experienced this as well, over winter we can easily get power cuts lasting more than 24 hours. Also, there is no gas here at all. So I think the u-turn is great for this un-nuanced piece of legislation.
  12. AartWessels
    I agree that if you don't heat upstairs, the mvhr and the thermal mass heated will not compensate for the heat loss. And indeed, a lower ufh power upstairs will keep the rooms slightly cooler than the living area. Differentiating the temperature in different rooms on the same thermal mass seems a bit unlikely, unless there is a heat loss issue.
  13. AartWessels
    Which will happen in an airtight house with mvhr anyway.

    Truth be told, more water enters Morayshire through the Spey than by rain. Although this year seems to have significantly more rain than others. So back on topic,blowy north, you.mean above Inverness then? Just sold some land near John o Groats which we originally would be building on. Before our plans changed and we moved to the heart of whisky country.
  15. AartWessels
    That's our nearest village. Couple if minutes from where we'll be building. However, shouldn't hijack this topic 😁
