think this should have you covered. https://www.tesla.com/en_gb/cybertruck

looks fabulous. well done. thank you for the blog and sharing your journey, I have enjoyed reading it and I hope I have learnt something from it!

an RPG character of mine inspired by Thorfinn Skullsplitter from Erik The Viking https://www.imdb.com/title/tt0097289/characters/nm0725956?ref_=tt_cl_t13

for us the country of origin wasn't a consideration despite us wanting to reduce our carbon footprint in general (we've chosen a local timber frame company for that reason). we wanted good quality windows at a decent price. simple as that.

fair enough @craig. I think Internorm really wanted the job so they cut their prices drastically. I did get another Internorm quote from a different reseller and their quote was substantially more than the Gaulhofer quote. I apologise if I gave an unfair judgement to the quote you gave us but it really does just show how much variance there is in window quotes depending on the job, the retailer and the manufacturer.

it's weird isn't it how the same manufacturers can be so different with quotes for different people. for us Ideal Combi were at the cheaper end of all our quotes and Gaulhoffer were more expensive that Internorm! we ended up choosing Norrsken, good price, service and quality of windows and doors. this all comes with the usual caveat that we've not had anything delivered or installed yet so my opinion could change.

as long as it's the stuff that is antibacterial I'm sure they all do the same job!

supply and commissioning only here as well. our quote states "Zehnder's ComfoTube ducting system" so if we don't get the Zehnder stuff I will see at the time if there's cause for concern. we've had to go for 4 manifolds though, 2 for the basement and then 2 for the above ground rooms. this will apparently help with fitting the 90mm ducts through the service void I have designed as we can send the larger duct from the MVHR unit through the service void to the manifolds above rather than running 15 x 90mm ducts. as well as other reasons that I was told and don't fully understand. I think it had something to do with pressure or air loss in the large manifold? and by having smaller manifolds it will make the system more efficient. something like that. anyway, it's not costing me more so I'm happy to go with their recommendations. ?

all of the above is with the caveat that I haven't actually had the design finished yet nor received any components etc. so my opinion of Enhabit could always change as we progress with it all.

Paul were cheaper on the design fee but more expensive on the unit as the price for the unit on the website is not available if you have them do the design as they include an extra on top for the 'journey' that you'll take together with them and for ongoing support. their website price is just for people who want to do it all themselves. I had both Paul and Enhabit quote and there wasn't a lot between them. in the end, for me it came down to Enhabit being more local to me (London as opposed to Scotland) and I had some really good chats with the guy on the phone and they reduced the design fee quite a bit. Plus they also do ASHP, Solar PV and other bits so I thought that if I went with them then I could maybe get them involved in the other aspects of the build that I'd need help with. I am sure I would've been happy with Paul though if I'd chosen them.

I'm sorry I can't help with your questions, but can only tell you what we're planning. we're having the Q600 and are building a basement and two above ground floors for a total of about 440m2. We're using Enhabit to do the design and calculations as I didn't want to make a mistake on it and their price was really quite good for the equipment and so I thought the design fee was acceptable seeing as the total price wasn't much more than I could've bought the equipment myself online! When I was getting quotes I had 2 companies recommend the Q600 and both of them suggested using the larger 90mm ducts to get the air flow required at lower rates and this is what is currently being designed for us by Enhabit. So, maybe you could consider that to assist with your flow rates? like I said, probably not much help but thought I'd comment just in case it does help.

2650 ground floor and 2100 windows and doors here too. hopefully it'll be fine! most our windows are down to floor level though so the whole window is 2100 high rather than starting at 900mm cill height.

but....but....but.... @Ferdinand said you'd sold it.....? I really don't have a clue. think it's probably best for everyone that I stop trying to be funny. maybe my kids are right after all.

whoops. I missed the post that he's finally sold it. once again I see my finger is as far away from the pulse as is humanly possible. ?‍♂️ in my defence, though, his signature is still asking if someone wants to buy some walk on glazing.

easily done. annoying swmbo that is.

and then who would make us laugh/would we laugh at* on this forum (* delete as applicable)

yay!!!!

who will you leave the walk on glazing to if that happens?

happy wife, happy life

I'm no expert but if you don't have any insulation then surely your EPC will be a lot worse that a "C"? hopefully someone who knows what they're talking about will be along soon.

We're slowly working our way through our self-build lighting design and I'm using Dialux Evo (https://www.dialux.com/en-GB/) software. it's very good. maybe you should give it a go and then you'll be able to try lots of different lighting to get the effect you're after.

did I also read somewhere that for low tog carpets it's best to run the UFH pipes closer together to get more heat per m2?

very nice! now I'm sure we made the right choice seeing yours. just got to build the bloody thing now.

we've gone for a red door! we think that with the black cladding and anthracite windows it should contrast beautifully. ?

wow! sounds complicated. hopefully our basement won't need such protection. I am also worried about losing room space. it's not so bad in most of the rooms but our plant room is in the basement and losing 100mm from that could mean things won't fit! thanks for the response. when I get nearer to the time of finalising our basement detailing if I have more questions I'll start my own thread on the subject. sorry again to the OP for hijacking the thread.
