  1. A long time. Back of a fag packet calculation (will need a white marker now as the packets are black). Current space and DHW ~2865 kWh/year, at current rate of 16p/kWh, £460. If that became 1/4rd of the price (CoP = 4) then £115 energy cost Water is 0.17m3/day, so 62m3/year, water is £1.9338/m3, so £120/year. So 30,000 [£] / 235 [£] = 128 years (house is currently 37 years old) Those are without VAT. If I was a bit sneaky and did not pay for the sewage, then I would save another £200. Sewage is £3.2871/m3 for 95% of usage, Standing Charge is £150.86/year So 69 years. Now I am not sure where the £30k borehole costs come from, but my farming mate had a 60m one done for £1800. They do a lot of drilling down here so even though it is often into granite, the local geology is well understood. (I would not recommend a borehole system for most domestic properties)
  2. Yes, But down here, if you can get drinking water out of it, you can save there (we have the most expensive water and sewage in the country).
  3. I can remember the days, not that long ago, when I put in my new DHW cylinder and you tried to convince me to get a SA. As much as I like the idea of a phase change water storage device, I dislike unproven technology, and the price was, and still is, silly.
  4. Or you have noise or view restrictions and little space i.e. town centre. A GSHP would fit my place nicely as I am in World Heritage Site.
  5. Let me know if they do, I may join you on the course.
  6. Welcome How old is the place, I have had 'Victorian' places, either end of her reign. They were both horrible to work on.
  7. Umm There is a saying in Farming, "if you want to make a small fortune in pig farming, start with a large one".
  8. I just had a look at my local council website and found some data about social housing in Calstock. https://www.cornwall.gov.uk/housing/housing-intelligence/ Seems that in April 2022, there was 8% social housing. I think that is not too bad for a small place. St. Ives and Pensilva is the same. Camborne, one the poorest parts of Europe is 15%, similar to Porthleven (a posh place they like to think) at 16%. Interestingly, St. Just, almost at the end of the country, has 33% (837) social housing. The county, as a whole (pun intended) is 8%. As for second homes, there is still a lot of ignorant bollocks spoken. The country as a whole has 11% second homes (household spaces with no permanent residents), 5% as according to the below map.. But the distribution is very clustered. Not many second homes in the middle bit, the part that is environmentally scared from 3 hundred years if mining and agriculture. I am still looking for the places that claim they have "80% holiday homes that are only used for 2 weeks of the year".
  9. Do not deal with Seamus, he can causes loads of trouble. I think that foundation system is a Kore one, which is pretty good.
  10. As above. Regardless of what people say and think, we are going 'all electric', it makes long term sense for many reasons.
  11. Rather than look at the floor area £.m-2, why not compare the differences on the total surface area £.m-2. That reflects the amount of materials/work much more accurately.
  12. Difficult one this. Polyurethane is made up of many urethane molecules. This changes the structure and may affect how well it bonds to different materials and the type of surface finish. I suspect that most sold are actually polyurethane, but the lazy marketing department have misnamed them. I have a parquet wood floor, a very cheap one. I used a brush/roller on, single part, polyurethane floor lacquer. Has been brilliant. As it was 20 years ago, I can't remember who made it and don't have the tin anymore.
  13. We do down here. Cornwall has pioneered DRH generation, still doing it. The local swimming pool was meant to be geothermally heated, £1.3m later they put a heat pump in. But that is not really relevant to domestic heating. As others have said, GSHPs are either ASHPs, taking advantage of local weather, or WSHPs, relying on deeper ground water. @ronaldgibbons Your floor insulation is going to be important. Most building companies are happy to say their designs meet building regulations. Not that expensive to exceed them where it really matters.
  14. Roll it up and take it to a cousin's shop in Tangier, for you, special price.
  15. Welcome Is the renovation in London? If so, which bit, it is a large city.
