We had a comprehensive SAP report done and from this the timber kit company had a report produced with recommendations. The SAP report was based on the as designed at the time but since then I’ve improved the floor insulation and gone with 3G instead of 2G throughout. It also assumed an as designed air change of 3.0 where my aim is to get under 1.0. I also plugged the numbers into Jeremy’s spreadsheet and the total heat loss in the worst scenario is 3.6kW which more or less tallies with the detailed SAP report. Consequently the ME guys recommended a minimum size ASHP of 6.8kW so we specced an 8.5kW Ecodan and this is what the installer also recommended. However the installer emailed me today and said that they’ve reviewed how they do their calcs after feedback they received and it means they now recommend we go to the next size Ecodan up so 11kW, the difference in price is only a few hundred quid. I called the ME guy that did our report and he said that doesn’t make any sense to him and recommends we stick to the 8.5kW. I’ve got a copy of the spreadsheet the installer uses so will plug our figures into that and see what it says but my expectation is it will match what I already have.

What is the advantage of getting certified anyway? I assume it costs money to do so. I’d have though that near passiv gets you 99% of the benefit without the apparent hassle and complication.

Our barn style is room in roof 1.5 storey with a large (16m x 4m) single storey porch attached to it.

If he fancies a holiday in sunny Perthshire 😂

Our flat roof is detailed to be covered with Alwitra Evalon V. Like everything else, it seems, I’m struggling to find an installer. I’m hopeful on one installer who is phoning me back tomorrow. It’s 64m2 with one rooflight. If I get no joy what are the alternatives. I’ve seen Sarnafil mentioned on here and that seems to be a more popular product and consequently has more installers.

I finally got the Catnic Urban quote back. This is the ‘easy you could do it yourself’ stuff if you’re keen. £9000 dearer than the VMZinc quote and £11,000 dearer than the Greencoat PLX stuff. It was £143/m2 So much for the good value for money alternative to the dearer materials. I forwarded the quote to the guy at Catnic as he’s been pretty helpful. I already had a material quote from Catnic so can see that the labour and margin cost was £18,000 and it’ll be more than this given they’ll get the material for less than me. Obviously didn’t want the work. Anyway confirmed the VMZinc today with the roofer. Flat roof next which us proving equally hard work.

😂

Obviously paid the hackers their crypto demands or cleaner has finished vacuuming

Sure but in the past they’ve had some fun 404 pages. This isn’t one of them. 😂 I’m with @ProDave they’ve been hacked or the cleaner as pulled the plug out for the vacuum cleaner

That’s from 24 Jan

The Black Barn in Broadford by any chance?

You can digest sweetcorn. It’s mostly starch inside. So chew it well. Any whole ones that escape the chewing still get the starch digested through diffusion just not the cellulose exterior

Let me join you for dinner as also on my own. Other half is on a work jolly in Paris. Teriyaki chicken.

Heb Homes In hindsight I would have preferred MBC. HH houses are beautiful (to my eyes I know they aren’t to everyone’s taste) but I’ve not found them very easy to deal with. Not sure if it’s me and them or just them. Too many errors, poor communication and response, poor attention to detail, everyone appears to be off sick all the time etc. We’re spending a lot of money with them but it doesn’t feel like it sometimes.

It just seems more prudent to check it while it’s being built to make sure it’s being done as required and, if not, corrections made at that point. Then a final check prior to kit erection. It says in their contract they’ll do a site visit while the slab is setting and if there’s an issue either the slab or the kit will be adjusted. In my experience so far in dealing with them and everyone else 2 weeks to correct anything isn’t enough time. It takes them that long to reply to an email. Our foundation will be completed mid March so checking it then would make more sense to me.

This might just be my inexperience. Our kit is being delivered week commencing 17 April. The groundworks start in the next two weeks and will take about a month. The groundworks are separate from the timber kit. The timber kit company has just told me that their kit erector will visit the site two weeks prior to the 17 April to make sure the substructure is ok. This will be the first time anyone from the kit company or their contractor will have stepped foot on the site. We signed the contract almost a year ago. This just seems unacceptable to me. Why check the substructure after it’s built why not do as it’s being built? Is this normal?

My son’s business thesis was on Greggs.

Supposed to or have to?

It’s common on here for folk make their temporary supply their permanent supply and leave the meter and supply fuse there then run SWA to the house. A lot of these installs will mean it’s more than 3m away. Mine certainly will be.

The connection can be longer than 3m you just have to fit protection to the nearest point on the supply side of the house which could still be an 80A switched fuse.

@eandg Might be too late. I’ve got the detail for this now I can share with you. I also came across this book which has the detailing you’re asking for. One thing that did catch my eye quickly skimming through the book is that for board on board the heart wood should face inwards on the inside boards and outwards on the outside boards. This helps the boards make a better contact should they shrink.

I have a redundant 137m borehole on my land near the house. Not sure how much heat can be extracted from a single borehole. I assume it depends a lot on the geology. I guess it’s maybe 5 or 6 kW? Anyone know. I literally never considered using it until reading this thread!

I ‘think’ I’ve decided on the zinc. The difference in cost is £2300 between it and the PLX stuff. As fate would have it I happened to be visiting someone today who has a zinc standing seam roof and it’s stunning. It was the quartz colour so weathered natural zinc which has darkened a bit since it was installed with matching guttering.

Can you link the suppliers as I can’t find any that are selling it at class 2 prices. B&Q quality is shocking. Wickes do have class 3 for about £15/m2 which is £2200 plus fitting for my roof albeit I’m doing it myself.

Ouch. The utilities are a scary unknown when buying the land. I did my best to get budget quotes as part of our due diligence and consequently we nearly pulled out of buying the land as the electricity was £26,500 and private water supply £24,000. However, like you you we didn’t want anyone else building on the plot as we were smitten by it 😂 The actual cost was under £10,000 for both in the end.
