  1. This is the bit the forum misses I think. Everything is very exacting for the required heat load. My house, with a single zone, 7kW ASHP on WC with a room thermostat performs pretty much perfectly...I don't need a stove...but I'd sure like to add one for those days. We didn't add one as it'd probably bring in more cold then good.
  2. We've 220mm thick roof panels with 50mm PIR internally. Plus most of that building is vaulted it works very well. One regret is that the steel portal frame is badly designed and causes a bridge but hindsight is a wonderful thing.
  3. I've a SIPS house with renderboard (Knauff Aquapanel) and K rend TC15 finish. Lovely walls with no expansion beads or unsightly breathers. 20m run on 1 wall...looks mega. Zero brickwork. Noise is a zero issue. Feels solid always, there was a very slight vibration when we had an Uber storm (90+mph winds) but that's all I'd say. You probably wouldn't have that in a block work house. We had no issues with getting a lender, we are with Barclays and house insurance and structural warranty no issue. SIPS is stiffer than purely timber framed so that may be less solid but I'm not sure. Self_build_ayrshire on Instagram if you want a look.
  4. Just an update. I had the third meter installed a few weeks back. All works now, SMS replaced it with an Octopus one (Kaifa brand) same type of comms hub but all fine now and working. Now I can access smart tariffs but need to decide between flux and go as we get an EV soon.
  5. Shelly EM basic clamp units, cloud connected. I've had zero reliability issues...I would highly recommend them. Think it was like 50 or 80 quid for the Shelly meter and two clamps which were 100A and a 20A.
  6. I'd say so. Here's my main consumption and my ASHP for the 20th November. Others skew it up to 23 quid cos of the Lazy spa...
  7. I've not read it all (but I will) We have a 7kW Vailliant arotherm,West of Scotland temps (so mildish). 5.1 CoP on heating (which I was surprised too see the other day) 3.7 on DHW. Which is set to 52 degrees and reheats straight away. On curve 0.6. One zone, no buffer straight off WC. Works like a dream literally not touched since we moved in May 2023.
  8. I've a Scudo throughout the house, valiant aerotherm 7kW ASHP, we store at 52 degrees (baring in mind the tank thermostat is halfway up) works perfect. Don't stress buy what you need and you can always go up a little temp wise it's only a little off you COP.
  9. I was told by the smart guy the companies this, but that can only be done in England for their commitment system. The whole house has 50mm PIR internally..likely the issue. Good to know. Are you guys in Scotland or England,? You check on the citizens advice website.
  10. I've a smart meter, it's actually my second and the third time they ve come out to try to get it to connect to no avail. I'm being told it's just the reception is crap or where the meter is in the house (We've terrible mob reception indoors too,So I assume SIPS houses are just like that). Our neighbours 400m up the hill works fine. It means I can't access Octopuses smart tariff for heat pumps and my Givevergy stuff and I've just ordered an EV and I cant get the nice 7p/kWh to charge it I have to pay the 23p/kWh. I'm in Scotland so it's on the DCC. Has anyone done this or similar? https://anengineersview.tech.blog/smets2-is-there-anybody-there/
  11. I'd install no more than 1 at each TV point. You really don't need them. I'd add an outdoor one for an wifi access point..
  12. It's SWA it's fine to sit in water. Also run it in duct, so if need be you can add a cable. I've a shed (I say she'd burs it's a 19m x 6m steel shed) with 10mm2 up to it, plus numerous ducts from my plant room running different cables different places.
  13. Is it a mixer on the bath? Turn the basin and bath to hot and see If they feel the same. If it is a mixer on the bath chances are someone has had the tap off it and it's not been replaced right. I've 52 degrees set on my tank, the bath (uninsulated pipe- there is very little point insulating hot pipe) is say 10m of pipe away, it is too hot to hold my hand under really at full hot.
