I only use it for lighting blocks, and this explains better than I can: It is very smart. Choose what to include in the replay and check on Presence Simulation in Loxone Config. Then at any time you want to switch it on you have the last week's actions recorded to be replayed. I include external lighting and lighting blocks from main internal rooms.

Very sharp, sits perfectly in its rural setting.

Nope, just meant being a little careful with it, if you want to keep it looking its best. We mistakingly dragged a metal cog crate across it and that left a scratch (as it would do with wood). No coating required, until it needs a re-finish, which I'd judge to be around 20 years.

I have a resin floor on power-floated concrete with UFH, but it's a PU Resin. Are you sure the product you have been offered is epoxy? My base layer is epoxy, but all other layers are PU. It's a warmer, softer feel than tiles with good wear resistance. I'm told the top coat with eventually show signs of wear, at which point it can be re-coated, which gives the option for a colour change. Still looks new after 7 years. We treat it like a wooden floor, so furniture on felt pads and careful with sharp objects, ie. not as hardy as Porcelain, but then if a dropped a hammer on it there'd be no risk of it cracking. Rugs can cause a colour change, a slight yellowing we have found, but remove the rug and a few weeks later the yellowing disappears. No grout lines or expansion joints is a big bonus, we have 250m² of seamless floor.

That's probably enough. I think it would need a dam either side of the wheel, so that most of the water went under the wheel. If it was a largish wheel, that was geared to spin the generator faster than the wheel itself, the resistance of the wheel would cause the upstream side of the wheel to rise. Something like

Not for power, water, comms etc. just the ASHP supply and return is insulated. I used a rigid 100mm duct for power and did wrap the outside in a 20mm thick foam, where it was cast into the concrete floor. I did this with all ducts to reduce their chance of fracturing if they were ever knocked. Grey rigid in the background close to the centre was for power and comms, blue flexi is water, black (long) flexi is for ASHP comms and the shorter larger black one that's taped up is the ASHP feed and return. Brown rigids are obviously waste.

It looks like you have a really good flow rate in the bywash, how deep is it? If there's enough depth I'd look at a pelton turbine, or something more like a water wheel, although you'd probably have to build the water wheel.

Mine is in 100mm duct, through an insulated raft foundation, without any airtight tape. The largest duct we have through the floor is the pre-insulated twin pipe duct for the ASHP, which is 150mm.

I wasn't aware of it previously, so thanks for the reference. Looks initially aimed at new builds via a developer, ie. they only want to speak to companies. I'm already built, but the comments suggest they will consider non-new houses in the future and the video mentions refurbs up to the required spec being allowed. It also mentions 10 years free bills on the video, contradicting the 5 years in the text. I've contacted them via my company, to see if I can "refurb" my self-build up to the spec they are after.

You've not mentioned distance, ie length of HDMI cable. What are you hoping to gain from centrally served HDMI, but only going to a single TV? From what you've written on your comms cabinet, I can only see the DVR/NVR as a possibly source that may need it. Does your IPTV "player" need to be in the comms cabinet? With Smart TVs they can nearly all run an IPTV App locally or run it off a local, small, cheap box/fire stick. If you centrally serve the source of the HDMI signal from your comms cabinet, then you also need to consider how you are going to remotely control it. I think these days, with Smart TVs and good value "set top boxes" that can render up to 8K and Atmos if you wish, I'd simplify the setup and have a few Cat 6 cables to each TV so that you are flexible for adding devises locally. There's great solutions like Plex for centrally managing your own libraries and you can add on a DVR for recording live TV and then stream it over IP straight to a an App on any of the TVs in the house.

From how far away? I routed HDMI to behind the TV, but only down to a unit below the TV where any connected "boxes" are located.

Nibe F2040 with SMO40 controller 4P Buffer Zoned UFH + Wet Duct heat exchanger on MVHR Nibe uses Degree Minutes for space heating rather than straight temp hysterisis. Factory set at 60 DM (range 2 - 2000) My ASHP typically runs for an hour and switches off for an hour or longer depending when DM 60 is met. The circ pump works in sniffer mode.

I'm not aware of any changes brought in in Dec 2023 that made it easier for LPA's to refuse an application without providing a valid reason, so not sure what's going to be reversed that will make it more difficult. LPA's have to justify their decisions for Approvals and Rejections. The Dec 2023 changes were mostly to increase housing supply, although there were some technical changes relaxing the requirements for LPA to have an identified 5 year land supply, which in some very specific circumstances removes an option to challenge a refusal. Have you got more info on what you are expecting to change?

Rachael Reeves' speech today (08.07.2024) hasn't added much to what was already known, but I guess it's moved it on to more than a manifesto promise. 1.5M homes over 5 years Mandatory targets for LPAs More intervention from Deputy PM for large housing estates and Infrastructure projects that are being held up at LPAs NPPF reform "by the end of the month" (draft changes published by end of July) Ban on on-shore wind removed. 300 additional Planning Officers Green belt boundaries to be re-assessed

My roof is simpler in some respects, but successfully done from 350mm I Joists. 300mm would have been fine but with a large roof area it improved the overall performance quite a bit going with the extra 50mm. Filled with cellulose and have no issue with sun loading. Don't know if it would be value for money for just the roof, but if you need an I-Joist roof designed and engineered I'm sure Cullen Timber Design could do it for you and provide a full cutting list.

2 brickies and a labourer?

Is the natural stone an unknown to them? or have you already got this on site and have they experience of laying it previously? Difficult for them to commit to a daily m² if there's an unknown. You're going directly to the trade, without any "management" fee, to keep your costs down - this increases your risk. It's not sounding like you have much appetite for the risk. It's a leap of faith, there will be many if you are project managing yourself. As you have a good recommendation, I'd say go for it, and monitor. Will you be onsite? I definitely would be for the first few days. You're adding to your risk if you are supplying all the materials. If they run out, you are still paying for them. Don't expect them to look ahead, the first you will know they are short is when they reach for it and it's not there. They'll be used to working on a managed site. Get a commitment from them that they are with you till they've finished what you need them to do. As a self-builder you are in a poor position with trades, you have no follow on work for them, so when their normal builder calls with an urgent job they will drop you. Don't pay anything in advance. But when they do invoice, pay swiftly.

However, UK is completing houses at a rate of 200,000 ±10,000 for the last few years. Current targets are not enforceable. (Not that I think Labour will do any better, but we'll see)

I would say central Government setting stronger new housing targets for individual LPA's to meet so that LPA rejections can be more easily challenged/appealed IF those targets are not being met.

Assuming you are in an OpenReach area, then it doesn't make a huge difference, but I went with Aquiss as it offered a 12 month contract (not 18/24) at a good price (50% off for first 6 months) and communicates excellently for the connection. They're pretty small and the MD works on the Support Desk. Free installation, but you need to supply your own router. For cost reasons only, I did swap to Vodafone after 12 months. Aquiss don't offer the 50% off for 6 months on the second year. OpenReach should supply 50mm smooth rigid conduit FOC. If you get it yourself, don't go smaller Cat 6 is fine/easier/cheaper. There's different shielding options, highly unlikely interreference will be an issue, F/UTP, U/FTP or S/FTP all suitable.

I do. If it's a (ASHP) manufacturer approved install I'd expect it to work as designed. You'd need to assess case by case to say a particular install is not working as designed. Agreed, as per my comment before yours.

I'm firmly on the "ASHP flow rate does not have to (and will not) equal heat emiiter flow rate" side of the buffer (3P & 4P) argument. Mine is designed not to and works perfectly well, meeting manufacturer declared COP. But, if you can avoid a buffer, save the capital investment.

Yep. Is it his first install? 3-Way before the buffer to select between buffer and UVC.

Showing the hot service only: Yes, but, the HW return is taking care of that, and with presence sensing reducing loses.
