    Cannabis Farm?

    @Dave Jones "knows for a fact" that heat pumps can't work. We had a system that was successfully doing that and the government pulled the plug on it. I do often wonder where parliament gets its information from, and how they can so consistently get the wrong end of the stick.

    You can read all about it here. https://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy.html Seem to remember the UK has had 3 years worth of gas left, for the last 15 years.

    BoE raised interest rates today. 0.25%

    Worth remembering that epsilongreedy is highly qualified in economics, thermodynamics, the social sciences and property development. And probably in import and export paperwork.

    Several people on here have used an architectural technician. They seem to be the people that understand all the rules and regs. At least they are not irritating little farts.

    I think you have to notify the DNO about the location of the isolators as well.
  8. SteamyTea
    Right. Just as a general note: Always switch the AC side off first to isolate the load from the modules, then the DC side.

    As you have a 5.1 kW system, why did you go for a 6 kW inverter? Or is that the very maximum it can take, rather than the nominal value?
  10. SteamyTea
    Hence I offer an alternative that also works. You doing get something for nothing.
  11. SteamyTea
    Whoops, missed that.
  12. SteamyTea
    No, but that will have to be done with optimisers as well. More interested to find out what the shading is like, installers are very happy to spend others money.
  13. SteamyTea
    No. I had forgotten all about it from when it was published, was the only time I read it. Usually find it easier to just work from first principles when it comes to thermodynamics.
  14. SteamyTea
    May be better off with just microinverters, rather than a main inverter and optimisers then.
  15. SteamyTea
    Do you need these, how bad is your shading?
  16. SteamyTea
    OK, you know best, can't be arsed to have to explain to you why you are wrong.
  17. SteamyTea
    That depends on how much is lost to the ground, less insulation, higher temperature needed. I am happy to cost things out, I charge a very reasonable rate.
  18. SteamyTea
    with what?
  19. SteamyTea
    Not wanting to start rumours, but I found that cream cleaned up my condition as well.
  20. SteamyTea
    Dunno, see what happens when it gets dark.

    I think the regs are soon to be updated because of low temperature heating system that use UFH. But the regs are a basic minimum and should be exceeded at all times. The marginal cost is very small. Too many people get hung up on windows because 'they want natural light', then have to buy blinds, screens, shutters and films to reduce the overheating.
  22. SteamyTea
    I beg to differ. Assuming UFH running at a mean temperature of 32°C, that will have a ΔT of ~23°C during the heating times, walls, which are generally of a smaller area (this does depend on design, number of windows and doors) will probably have a ΔT of ~15°C for the heating season (does depend on where you live and how hot you like your house).
  23. SteamyTea
    Under the heating system. There are a number of slab/flooring systems that reduce the thermal bridging. Some will depend on your wall construction.
  24. SteamyTea
    Belfast branch maybe.

    Just how important is flow and temperature stability for your showers. The easy, and cheap way to get both is a vented DHW cylinder with a cold takeoff from the F&E. Then pumps for the showers. Only think to be wary off is overpumping and damaging the cylinder. But that can be calculated at no cost.
