  1. What about the Fox Series? I've just had one installed here. They seem to be fairly popular and the app is quite good.
  2. I would, make sure to knock up some sandwiches to keep them going 😄 I'd even consider reaching out on Fbook for a labourer for a few days. Always someone looking for a few quid. Someone on here might be able to tell you what to offer them for a day's work. Both options are going to be so much more economical than what your builder is quoting. Good luck!
  3. I genuinely think this is being made more complicated than it needs to be. We fully renovated ours before sorting the garden. It was originally on a slope, which we completely levelled (by hand). Since ours is split across two levels, we also had the extra job of carrying the soil up 8 or 9 steps and through the house to get it out. It did take time, but by chipping away at it for an hour or two here and there, it eventually got done. In the end, the only real difference between spending a fortune and doing it cheaply is a bit of hard work and sweat. You can then spend that money on nice things 😊
  4. Volume = Length X Width X Depth. Soil density = Loose soil ~1.2 t/m3 - wet soil ~1.5-1.7 t/m3. Weight (tonnes) = Volume (m3) x Soil Density (t/m3) Not that it really matters 😄
  5. 3-4 tons were moved from my back garden through the house. Heavy-duty rubble bags were used to do this. If you go down that route, I'd suggest dumping it into the front garden somewhere and hiring a grab wagon when you're finished. Make sure to dump the bags out, though, because they will only take away loose soil. We didn't and ended up paying a fortune for skips. Get a couple of rolls of that sticky carpet protector too. Saves the clean up.
  6. I've gone down this rabbit hole, and I have an ASHP. I came to the conclusion that it's probably not worth it. Buying the gear, then fitting it and plumbing it up, then who knows how effective it would be. Instead, a mini split system probably works out just the same, or not far off in the end. Bought and fitted for 1.5-2k, or you can buy the pre-charged ones for £5-600 and do it yourself.
  7. I doubt this house had any radon barriers, but MVHR dropped Radon levels: https://www.heatspaceandlight.com/mvhr-lowers-radon-levels-cotswolds-cottage/
  8. Not sure if you're on about the ducting supply and exhaust air (house side) or the supply and exhaust (external). Regardless, there's always the risk of condensation in the winter. In the summer my loft space is gets extremely hot so I have individually insulated all ducting (house side) with ISO sleeves as well as 300mm loft insulation on top. Just belt and braces to avoid the house overheating (even with summer bypass). I don't know if that answers your question.
  9. Yes, you can feel a very slight breeze on a back of your hand under the door when closed but it defiantly shouldn't be whistling through as others have said. Sounds like its not been commissioned properly in terms of correct flow rates and balancing. Mines fine and I went with lower flow rates from the previous versions of Part L after reading through a lot of info on here. Best thing you can do is do it yourself. Calcs are straightforward and you can hire an anemometer for week.
  10. Just send your floor plans to BPC Ventilation and they'll do it for you and provide you with flow rates. That gives you a good starting point. Just an FYI from what I've learnt along the way (some may disagree/correct me): Kitchen extract should ideally be located above/adjacent to the sink, not the stove. All plenums should have a minimum clearance of 300-400mm from walls. If your floor joist permits, try to locate supply valves above/adjacent to the radiators in the bedrooms and other living spaces. Apparently, this helps with convection etc. They say locating the unit in a warm room rather than a cold loft is better in terms of efficiency. I've not had any negative experiences yet though. Don't underestimate the work involved if it's a retrofit and you are slightly OCD.
  11. @low_and_there which method did you eventually go for? I've got an almost similar scenario to address.
  12. I’m not too sure. Most appear to just lay the bare ducts under regular loft insulation 300-400mm. I wanted to get mine up and running prior to getting the loft insulated. I also thought it would be good practice to lag the ducts in case any loft insulation became displaced in the future. I got mine from BPC: https://www.bpcventilation.com/iso-sleeve-pipe-insulation
  13. Mines in the loft. No where else to put it really. Might end up ‘cladding’ the sides with PIR, at some point. On the coldest day we had last week, the temperature difference between the room extracts and supply valves was hovering around 0.3-0.5 degrees. There’s no insulation in the loft yet either, but ducts are lagged with 80mm ISO sleeve.
  14. It’s currently-2 here. What’s peoples indoor humidity readings been like? We’ve had our system operational for around two weeks and I suspect various elements have been drying out over that time. We’re sitting at 55% at the moment.
  15. Thanks for the insight. I’ve been looking at carbon filter solutions on here, seems most diy them. The house isn’t particularly airtight at the moment but it’s a work in progress Yes, I’d be looking at direct air with a duct to either outside or from under the suspended floor.
