    Just checked mine. Water was £1.9219 Waste was £3.1317 X 0.95 so £2.9751 So £4.9m³ Then add the daily charge of £0.1497. I used 12 m³ over 93 days. So 129lt/day. With my government rebate of £50 a year, and the Water Share credit of £13. Plus the £30 Stop the Drop of £30, my last bill was £33.63. So £0.0028/litre. Really not that bad when I look at it. Does seem perverse that to save water, SW Water makes it cheaper. But at least central government are coughing up a bit to help. Off to have a deep soak in the bath now.

    I think you are out, should be 0.3p Mine is the most expensive in the land and was 0.53p/litre last year I think.

    Have you thought of a mansard roof? If the steep angle is south facing, it is good for winter PV.

    Short notice I know, but I have to come up to clear out my Mother's home as we may have a buyer. Was chatting to someone on here earlier and I suggested that after a few years of saying we should meet up, we have provisionally decided to meet. I know there are a few others in Mid Bucks and the surrounding area, so all welcome. It has been suggested (that is science talk for 'I said') that we meet at The Five Elms, Weedon, but just noticed that it closes at 5 PM on a Sunday. The only other place I know is The Watermead, just on the outskirts of Aylesbury. I have not been there since I moved away in the late 1990s, so may be horrible, but it is by water. 10 Lakeside, Aylesbury, GB HP19 0FX Suggested time 6 PM. I am open to better suggestions. I did get asked to not go back to a pub at Marsworth once, but then had a call from the Landlady apologising that her husband was drunk. Not been back. I shall leave it here and see who is interested.

    Think you answered your own question. Run it though a voltage drop calculator and see what comes out.

    Make one. Could be like a rock waterfall, or one in the shape of a fish, or camel.

    Just had to get rid of some of the skew.

    Depends who is digging for the drains.

    I used to be, but the blocks of flats that have been built in the UK have not been very successful, even the posh ones. Housing, as opposed to all urbanisation, only takes up about 3% of the UKs land. Unused farm land takes up several times more.

    The only really big difference is in the professional fees and connected services, they can be spread across many houses, rather than just one.

    Chart the data by date and hour, then you should get a good idea of that is happening just from the load values.

    You will have to elaborate

    They had a large chain downpipe at Exeter University when I was there. Was just another reason to dislike the place.

    The man that has a great face for radio. Like Bridget Bardot, the years have not been kind. And he wees on all his vegetables, so don't eat at his house.

    Straight from the boiler at moment Assuming these two are related. To take advantage of the PV you will need a DHW cylinder. This can either be separate from the space heating system, or integrated with it. I am pretty sure that a combination gas boiler, which by the sounds of it, is what you have, can be rejigged to act as a system boiler. There are a couple of plumber on here that will know for your make of boiler. Do you know your space heating load, especially the maximum power for the coldest days? Do you also know what temperature you want the UFH to run at, lower is best. What is the nearest town to you? Cornwall is a long county and Mid Cornwall to is anywhere between St Awful and Hayle.

    I would have thought that fitting a buffer/thermal store, which has an element built in, between the LPG and the UFH would do the trick. How are you dealing with DHW?
  18. SteamyTea
    Do you have an electrical energy usage profile? Without one you are just hoping that lots of PV and oversized storage will cover your needs, this may not be the most effective way to design a system. Below are some charts (as we all like charts), that are from the coldest week I had last year. First chart is for the whole week, then charts for each day to show the variations in usage. There is not a great variance in usage, which reflects the decrement delay and consistent lifestyle I had that week. Below is the coldest day

    The real issue is how that money is spent. Does it genuinely improves local infrastructure or just goes to general expenditure. We have to accept that no matter where a development is done, even on polluted industrial land, there will be ecological damage. Really depends where your personal ecological interest lay. This was an interesting listen, how microbes can eat up pollution, and how quickly they can develop to a new environment. https://www.bbc.co.uk/programmes/m001lyrn

    Are these solar thermal or photovoltaic, or one if each? Can the heating be done via a buffer tank i.e. an ordinary immersion heating element in the buffer, then the LPG connected to the same buffer. A diagram of the systems is a good start.
  21. SteamyTea
    So what sort of thing you thinking of trying out? There are a few of us in Cornwall, and a couple in Devon pretending to be this side if the Tamar.

    Is this a job advert?
  23. SteamyTea
    Does it smell any worse than the neighbours cesspit? The neighbour you complained about.

    Not looked at your plans as I tend not to critique others designs. But if you can get a lot of South facing PV in the roof, you can easily run summer cooling from it. Going low energy is really not that hard, a sensible floor/roof area to wall/window ratio gets you most of the way there. Then get airtightness below 0.5 at 50Pa. Then insulated the largest, coldest (generally north and east) walls as much as you dare. No one ever said that all walls have to be insulated the same amount. Building regs are only the starting point, not the end point.

    Temperature is the mean free path speed of a molecule or atom. Mean temperature is the mean of the sum of all molecules. When water is above 4⁰C, the density reduces with temperature rise. So at the top of the cylinder, the free path speed is going to be higher than lower down the cylinder. Some of those top molecules will be above 100⁰C. This is what caused evaporation. Nature is quite wonderful, and often not intuitive.
