I've set up CloudFlare and everything appears to be working as it should. Many thanks for the suggestion.

Why we need "Net zero"
saveasteading replied to Beelbeebub's topic in Environmental Building Politics
Having been in the shaft under construction for one, it felt expensive even before any mechanical kit. The land-rover drove us into the mountain to the man made cavern. There may have been 2 tunnels, one for pipes and one for people. Very James Bond. -
We've had it fitted as part of the deal. Very fast when nearby. Very slow to nil at 30m away in the site caravan. As the project is all metal clad, we will have to provide boosters. The fitter asked why starlink when there was an O2 mast within sight. Well, because O2 don't say that reception is any good in the area and because they are right... it's very poor.

That would be the same for (new) pumped storage though. Pumped storage was commissioned so that nuclear does not have to throttle back at night. So probably very expensive.

Will take about 5 minutes to set it up with CloudFire, just download the apps and away you go.

MVHR Design And Install
Alan Ambrose replied to Adrock's topic in Mechanical Ventilation with Heat Recovery (MVHR)
This kind of thing. It also generates a list of Ubbink components to buy (surprise!) but the calcs apply to any manufacturer's duct of the same approx diameter. -
I think generally this is the problem with all types of energy - there still isn't a consistent way to assess them on a like-for-like life-cycle basis. And each side tends to provide limited or incomplete information.

What battery drill should I buy? The choice is bewildering.

So on my phone I have turned off auto DNS and in doing so my WiFi calling now works but I have removed a level of security. If I do as @SteamyTea has and use a private DNS such as CloudFlare then the security is improved but will my WiFi calling still work? I guess I can try it and see!!

MVHR Design And Install
Alan Ambrose replied to Adrock's topic in Mechanical Ventilation with Heat Recovery (MVHR)
The spreadsheet is pretty simple really. The other option I used for comparison and the one the BC preferred, presumably because they were independent calcs, was the free online Ubbink ‘Aerflux Project Report‘: https://www.ubbink.com/int/advice-service/aerflux-configurator/ -
Air hooks for Radon membrane
Spinny replied to flanagaj's topic in General Self Build & DIY Discussion
Here is what was done on my extension - see pics. The Radon barrier - which also functions as a DPM was run wide as a continuous piece. So it runs across underneath the insulation and heated concrete slab above, through the inner leaf of the wall, then vertically up the outside of the inner leaf, then horizontally across the insulated cavity and the outer leaf. A seperate DPM is installed across the inner and outer leaf so sits immediately on top of the radon barrier on the outer leaf. Cavity insulation below the radon barrier was XPS as this was considered more robust should any moisture get into this part of the wall, then PIR above the cavity tray formed from the DPM. I am not sure why your architect seems to be specifying so many different membranes and joining them in the way shown in your drawings, when I would have thought one continuous piece could be used. I would encourage consideration for the practicalities of what builders are going to actually achieve on site. I think it is going to take a very - perhaps uniquely - diligent and conscientious groundworker/brickie to continuously join two membranes all around the perimeter of a build ? -
DNS stands for Domain Name Service and is the things that changes website names to IP addresses (simple explanation). There is such a thing as DNS spoofing, which intercepts call to DNS and provides a "bad" IP address. So, yes correct DNS setup is crucial to a secure network.

100mm perforated pipe... recommendations
Alan Ambrose replied to JackOrion's topic in Landscaping, Decking & Patios
FYI you can get geotextile socks which go over the perf pipe rather than sheet Terram. -
Like any functional part of a property, SUDS needs maintenance. It always amazes me that in the UK that people are prepared to spend a fortune on fancy products and materials but either don't consider - or actively begrudge - the small amount of money or personal time required to ensure longevity. Instead they moan about ticking boxes. tobermore-hydropave-permeable-paving-maintenance-guidelines-v1.0.pdf Where I live the properties on the other side of the road are all lower than their drives, which slope down towards the buildings. These were originally built in the 60's with concrete surfaces and experienced constant flooding. Most have now changed to permeable paving and no longer have to worry about weather forecasts. One is a tight-fisted old curmudgeon who jet washes his 4x4 every Sunday morning at 7am. He never once directs the jet wash at the mud on his driveway or brushes it off. His house flooded twice last year.

12 May - net zero day
Alan Ambrose replied to RedRhino's topic in Energy Efficient & Sustainable Design Concepts
Congrats. Also, good to think there’s light at the end of the tunnel. 😀 -
Back on this... finally found one close'ish to home so bought myself a 2nd hand - nearly new du-200, looking for disc recommendations please for porcelain 8mm through to 10-11mm, saved a chunk on the cutter so have some funds to invest in a good quality disc.

It looks like the frame only comes with wall fixings for a "solid" wall and they look too short for a Nudura ICF wall. Has anyone fitted such a frame to a Nudura ICF wall (polystyrene)? Did you use: 1. threaded rod resined into the concrete? 2. Something like a rawlplug bolt? 3. Added some other solid material over the polystyrene to attach the frame to?

Well I'm chuffed to bits with the performance of our new self-build house. With another 6 weeks to go before mid-year our 2026 electric bill has balanced out. By mid-year we should be in credit by about £150, so maybe £300 for the whole year. That is for DHW, heating and domestic load. 2 people in permanent residence, with guests, 200m^2, thermostat set at 21.5c throughout. We run a sauna but not an EV. Contributing factors in approximate order of importance: High levels of insulation in floor, walls, and roof (MBC high performance timber frame) Very good air tightness (0.8) Large solar array 3kw facing SE and 6kw facing SW with no overshading from trees / chimneys etc Octopus Flux tariff Tesla Powerwall 3 battery 5kW ASHP UFH Triple glazing Each item has value in itself, but they also complement each other e.g. the UFH reduces heating temps which increases the efficiency of the ASHP which reduces demand which . . . I just need to tell Octopus that they need to set up a Direct Debit to pay me : )

You're talking about Sizewell C, I was talking about Hinkley Point C. In both cases, though in different ways, the funding model is designed to recover the decommissioning costs from bill payers. I agree though that nuclear power is expensive (Hinkley strike price currently £135/MWh) and that decommissioning costs are a risk. At least the funding models are intended to recover all the costs from consumers. My post though was making the point that renewable aren't cheap either. That's because the system costs don't show up in the e.g. £91/MWh strike price agreed for off-shore wind in AR7. The point I was making was the facilities you mentioned - battery storage, hydro storage, hydrogen - are expensive pieces of kit and will only be required to run when the wind doesn't blow. So their capital costs will have to be recovered from the few MWh of electricity they produce, which makes that gap filling electricity very expensive. And if we want to compare intermittent wind with firm nuclear on the same basis, we have to add the cost of the gap filling to the £91/MWh ... in which case wind won't look so cheap. And that's even before we talk about the cost of the grid upgrades required for off-shore wind. BTW, I strongly support decarbonisation and that renewables will play an essential role. I just like decisions to be made on the right information.

EDF go bust? Wholly owned by the French state. Seems rather unlikely.

Hold the chunk of timber up to the ceiling on a couple of props measure up from floor both ends and mark the timber use a block of timber to scribe the ceiling contour on to your length of timber plane it to fit.

Keep it wet, keep the u bend completely full, if you let the air get to it it will harden. get a piece of 15 mm hep 2 pipe and ram it around the trap, back and forth take detailed timing of how long this takes and charge the flooring contractor you really are attracting some muppets.

The pea gravel spec came from the gabion engineer, in this case it's within backfill that is specified as 6N. Attachment here. -
Regulations regarding access height to equipment
Spinny replied to jimseng's topic in Regulations, Training & Qualifications
Well I am putting network stuff in a cupboard from about 1.8m upwards. Not a new build though. Most existing houses are too small, so needs must. I wouldn't have thought words like 'should typically' are really worth the paper they are written on. Designing buildings on the basis of the occaisional needs of a small minority of the population is not always possible or sensible. Thinking about whether to get a swing gate network rack like this... https://www.amazon.co.uk/Tecmojo-Network-Computer-Equipment-Mounting/dp/B0DBRBKRS6/ref=sr_1_3?crid=QIGN7P0D9QQU&dib=eyJ2IjoiMSJ9.UQTMW0pCAUkMMyTWRDqLYSZVAAHxOZSB0NEpnpVG6j4GuVnaO47peoo6JwxBOdPiAZgJ8jIDTt9vbcV3U-K-3QQXGMQl2E0FiDyG8rDh_F6ba2sMZgZOKcPzmU1kz4C6-VPQGv-eyMNNCD0vv2FqQhXaCPaLLUmAhEIvkHVQ-f6OwqzbkzwGBtgfoyZYSwGpOyl6YB6-SHDzrqm1z848DAnW5kietHJB3wEhJLzsNrE.JXx9IdVn5dpraQR2flo5NcFZUIruGvVv5EKVZ7_QZl4&dib_tag=se&keywords=swing%2Bgate%2Bnetwork%2Brack&qid=1778536216&sprefix=swing%2Bgate%2Bnetwork%2Brack%2Caps%2C123&sr=8-3&th=1
