    First question, how much insulation under the slab do you have? And for that matter, your friends, he may just be keeping the worms and moles warm.
  2. SteamyTea
    Or chaotic
  3. SteamyTea
    Just talk about cloud. or lottery ticket winners.

    is that a real word? Oh yes. https://en.wikipedia.org/wiki/Stochastic

    Needs a different glue. Ow about a cheap plastic box, the kind they sell in PoundStretchers (which is misnamed as a £ is a fixed size and mass, though, due to FOREX, can have a different purchase price, even if the purchase price parity is similar)
  6. SteamyTea
    You can't. It comes down to the statistical probabilities of the stochastic nature of weather and house usage. Or just make of from plastic. Easy to get a sheet of PVC and some 'plumbers plastic pipe glue'.

    It is not the material, it is the temperature and humid hitting the dew point. Dew Point Temperature = Observed Temperature -((100 - Relative Humidity) / 5) OR Dew Point Temperature = ((HUMIDITY/100)^(1/8))*(112+(0.9*TEMP))+0.1*TEMP-112

    Any help https://www.engineeringtoolbox.com/heat-emission-radiators-d_272.html Yes, it is very annoying and assumes that people never make an error, and are always re-reading their posts within half and hour pf writing them. also found this list https://www.aelheating.com/blog/how-to-calculate-delta-t/ 5 0.050 10 0.123 15 0.209 20 0.304 25 0.406 30 0.515 35 0.629 40 0.748 45 0.872 50 1.000 55 1.132 60 1.267 65 1.406 70 1.549 75 1.694

    Stuck tap washer, get the tools out.

    I had to Google it. https://kosnic.com/dali-push-1-10v-dimming-whats-difference-choose/ Seems that a short push turns on or off, hold down for longer and the output changed.

    Building Regs is only one interpretation of the laws. Not sure how much the actual BSI standards woukd cost to buy, but worth asking local library if they have access to a copy.
  12. SteamyTea
    You could consider a Sunamp. Though they may have other problems. Space heating can be done with storage heaters, then take advantage of the cheaper night rate. As this is a rental, getting rid of gas is a sensible move, saves on annual certificates, servicing and, if it does leak gas, a 'Ronan Point'.

    Have you calibrated the unit? Some need to be placed outside where PPM is about 420.

    If the grid voltage is at the upper limit, the inverter will have to disconnect or try its best to limit the voltage. It may do this by pulsing, which is only turning off and on again, quickly.

    She does, finds me tasty anyway
  17. SteamyTea
    Yes, at every level. But you can make one of your onanist movies in it. Having seen one that had been in use for a while, in a North London club, I can tell you that you will be disappointed.
  18. SteamyTea
    There is already a way to sell back to the grid, but you have to have an MCS installation. This, at the moment, makes it not really worth while.
  19. SteamyTea
    Only at a certain time on a very sunny day. You only have a kettle on for a minuted or two, the panels will be generating something all during the daylight hours. So you will still be loosing a lot to the grid.
  20. SteamyTea
    Well the washing machine will probably peak at 2kW, kettle at 2.8kW. Computers can be anything from a few watts (mine used 8W) to 300W for an old Apple Desktop. So realistically your PV will not cover your peak loads. It is a rare day they produce peak power in the scheme of things. What they can do is reduce the amount you import while those heavy loads are on. When those loads are off, you need to divert the power to something else. This is why water heating is useful. Don't get Power (kW) mixed up with energy (kWh)
  21. SteamyTea
    Ah right, then it could well give a strange reading.
  22. SteamyTea
    What are your daily needs? See previous answer. But heating up a tank of water is a lot less capital expenditure.
  23. SteamyTea
    Or in your case a wheezy dog kennel.

    Assuming that there are no restrictions about how the van looks, you can improve the quite easily and cheaply. You can externally insulate them, stop airflow underneath them, fit an outside woodburner (they will kill you slowly) and pipe warmed water though to radiators, or an UFH system. Make a sound insulating box and stick a small generator in it and run a heat pump. An ECOCENT to to the water, and a cheap A2A for the space heating. Stick some PV on the roof, a few batteries and then get 'free' power. £10k would turn a pretty useless van into a very good one.

    Isn't PAT for portable appliances, not fixed ones. Are they testing the PV, or things plugged into it? Not sure you need to have things 'plugged into the mains' to PAT them.
