  1. Water heated via ASHP, will get a reducing valve to be safe, thanks.
  2. What purpose does the pressure reducing valve have? Will try the bucket tomorrow, thanks.
  3. Checked tap(albeit a make shift one) at full bore that was reading 3.9bar though that was the middle of the day, will try it morning and evening too. Is it OK to plumb toilets handbasin etc direct from main?
  4. Is a water storage tank essential, currently connected to mains and hope to drill a well before the year is out. Had initially planned for pumped tank in plant room but after checking the water pressure (3.9bar) just wondering if the tank is now needed. I know if the mains were disconnected you would have the storage tank bit that wouldn't last pissin time in our house. Any ideas?
  5. The top layer of steel looks awfully close to the surface compared to ours

  7. Thanks James, will check with spark when he's back in January and plan to reroute the cables
  8. Had to look up derating cables, actually the mains cable 25sq is running through and cables for the ASHP. Spark said not bout derating these, is this now an issue?
  9. Made a bubu when running ducts, not enough space to run the two pipes in one duct including insulation so now may have to run either the flow or return in a duct that has cables. Would this be OK considering it'll one length no joins? Alternatively we'd have to to go through the walls which I'd rather avoid unless necessary.
  10. Just looking at the heat geek page as I needed to interpret that table. Am a little smarter now than when I woke up, thanks John. So there is no need for the buffer as per table. Re the plumber, it's what i thought, but God knows how long we'll have to wait to get a new guy this time of year.
  11. Thanks John. 9Kw. There is a buffer that came with the kit, though not sure if he'll be using it. If he is, it will be 9/10 m from the HP. Again 9/10m to cylinder from HP. I believe there's a pump on the unit whether or not that would be fit to drive the water around a 1900 odd bungalow I've no clue, Imagine another would be required if not?
  12. Plumber has given me a list of items to get for second fixing house. Among them is 1"acorn piping and lagging for the flow and return to outside. According to heat pump installation guide it states 28mm copper or 35mm if using plastic. I've pointed this out and his reply was, usually use 1"acorn but your heat pump could be different. I know he's never fitted a monobloc HP before only split systems, but am concerned as he doesn't appear confident in comparison to other trades that I've dealt with. Should I be looking further afield?
  13. Won't go wrong with Hilliard and his team.
  14. My preference would be to tile the whole floor and sit kitchen on top rather than tiling under units also don't fancy having to lift/move stone worktop to accommodate tiles if moving the units is an option. Looking like fitting kitchen first is the only option, thanks @Conor @Gus Potter. BTW the decoupling matting is .85mm thick, so not really that thick.
  15. The floor is concrete, been poured since August 2023. no cracks to date but have been assured that it will crack when heating is up and running. I guess as the tiles are costly may be foolish not to use matting? the guy suppling the tiles thinks we're mad to use it(matting) even though would be supplying it,go figure! you could well be right re. tiling early.
