    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

    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.
  5. 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.

    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.

    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)
  8. SteamyTea
    Ah right, then it could well give a strange reading.
  9. SteamyTea
    What are your daily needs? See previous answer. But heating up a tank of water is a lot less capital expenditure.

    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.
  13. SteamyTea
    It may just be a function of how the refrigerant gas works best. As long as the lowest temperature is high enough to do the job, then the rest can be sorted with airflow though the heat exchanger and temperature differences between fluid flow and return flow. They may be more efficient as well.
  14. SteamyTea
    That is quite interesting. I wonder if a heatpump cannot vary the temperature, a buffer tank and temperature blending valve should always be fitted, regardless of the system size.
  15. SteamyTea
    Good. Knock the UFH down to 30. Don't muck about with little steps. If it is too cold, up it.
  16. SteamyTea
    Hopefully. It would be a very poor design if it can't. Where system boilers fixed temperature in the olden days? Seem to remember my old Baxi only had on/off and a diverter to the CH or DHW.
  17. SteamyTea
    I know very little about the mess that is plumbing, but is that an old fashion idea where one radiator was always hot, to stop the boiler blowing up or something. Is there a risk by turning down the flow temperature, that the DHW may not get very hot. I would expect the controller to sort this out, but if someone that does not understand HPs fitted it, they may assume differently. Yes, we think an airing cupboard is normal, it is really a failed design.

    Lack of pipe insulation as well.

    What this one http://www.uksprayfoam.co.uk/icynene-medium-density-foam-insulation/ Not used in the same situation. All I am really saying is that the right product has to be used.
  20. SteamyTea
    Icynene is open cell. http://www.uksprayfoam.co.uk/icynene-spray-foam-insulation/ There may be good reasons to not use closed cell in some places.
  21. SteamyTea
    Yes, and often made more sense than some legitimate contributors, and less offensive.
  22. SteamyTea
    No, you can do both internal and external in different places. The only thing to be careful of is where they meet. A condensation risk assessment should be done for those parts. Not as hard as it sounds. As it seems you are basically gutting the place, the one bit that is hard to do, the external wall between floors, becomes relatively easy. Just make sure the joists are not going to be affected by the temperature difference, which is what affects the dew point.
  23. SteamyTea
    Yes, it is barmy putting a time limit on it, how do I now get all my posts deleted.
  24. SteamyTea
    That's interesting. Did not notice that when I had a quick look at their spreadsheet.
  25. SteamyTea
    Or water, even
