  • some form of heat loss survey

    We had these guys in
    https://cheeseproject.co.uk/

    Was very cheap and quite interesting. They seal up your house with plastic, you heat it nice and hot on a cold day outside, they use big fans to increase the pressure inside, then they use a temperature gun thing and you get a nice video of all the heat escaping.

    I haven't actually got round to addressing much of it but it was quite illuminating. For example I never would have suspected about half our light fittings have much bigger holes than necessary and tonnes of heat escapes through them. You couldn't see it until the light fittings were removed.

  • That looks like the sort of thing I need but I’m in Northern Ireland and they wouldn’t be to handy for here. Thanks for the tip though.
