Ive given up trying to work out reasons planning give for refusal sometimes a man had a plot with slope on it --wanted to build an earth sheltered eco house NO- build a normal scottish type long house on the flat bit was the reply the way he wanted to do it --you would not have seen the house at all so go figure that one out

you could set in studs before pouring the walls for attaching things outside of render? fit plenty and cut of flush what you don,t need? hardly a big deal holes in concrete with modern drills to fit a facia board to mount things any way you could fit it before render -and render up to edge ?

hard to justify GSHP in uk with us not getting very low continual winter temps ,extra expense etc IMHO

very reliably --glass flows -look at windows in a very old house will be thicker at the bottom

my thoughts have always been that untill we get orbital manufacturing plants --where energy from sun is much better and being able manufacture in a near vacum --then we will not get these technolgies at cheap enough price /carbon offset

so how much £ of mains electricity can these things hold --assume 9.6kw 4 stack system ? probably looking at it wrong --but at 15p per kw thats = £1.44 of electricity ? £3k =seems a lot to invest to save the occasional use of it? correct my thinking please you could buy a good stand generator for that ,if its power cuts thats the problem

will it really not depend on how big a PV array you have and if you intend to sell lots back to grid in the summer ? that is only reason i can see for a 3 phase supply and at present rates that is a long term payback for that extra generation capacity when batteries come down in price and you can be classed as a grid smoothing terminal --eg they buy it back from your batteries when needed to keep grid happy -- then maybe lots of variables to work out to make that choice . I have been getting quotes from PPA solar farm installers and the difference in how much per acre the different companies are quoting is wide for 25 acres --anything from 5mw to 7.5mw and thats with them basically renting ground and just paying rental for it

at least you have now seen the worst it could possibly get and design accordingly

If it was me I would swop plaster board for foam backed type --then you have insulation and keep you service void +extra sound proofing as well use 37.5mm insulated plasterboard and you get 25mm of insulation sounds to me like the TF company are trying to keep to abosulte minimum frame thickness ,or it would just be deeper in the frame and could have thicker insulation behind the service void to get spec you need 140mm frame ,rather than 170mm frame ?

I,ve got a big garage /warehouse 30 miles from stranraer --maybe a biz oppertunity ?

maybe me --but the pictures seem to show the meter is set in concrete --that cannot be correct -it should be in a meter chamber ,so it can be replaced easily by simply turning off the toby and uncoupling the pipes without any digging it also looks like it is not deep enough --is that 450mm under the ground? that will not be to spec --so while you are at it get that sorted to water board spec as well if i am talking crap ,then sure a plumber here will put me right

try it on the floor first and see how much deflection in the shelf with the weight you going stack on it

If you can get a helicopter to carry same 1500 rounds (7ton ) of depleted uranium shells and that monster gattling gun --then yes retire it till then there is nothing that can lurk about like an A10

600mm wide shelfs will need to be very thick or lots of support brackets . -you can get a lot ofr weight ona 600mm shelf -so really you should be thinking of same spacings as floor joists --16" unless you not going to fill the shelves . mdf --NOt my choice it will bend over time real wood or 1" plywood

A10 that one i would like to have flown with a full magazine and some tanks for targets

he was always sticking them on a wing tip proper flying

yes your devon pilot often did tree top fly bys above my house --waving at the wife i think nice to see an old piston twin being flown other than in a straight line

there is a house on the river Nith at glen caple that is built on theesturay banking which is mainly mud =sand etc they dug down and made a raft from 1metre cubes of eps and linked them alltogether then poured a concrete slab on top --that was built 25 years ago --still there so good eps slab works on anything really

buy correct resin coated T+G roofing board ==not std osb

that would have been robert bolton -king -- our 12000hr+test pilot / type instructor - or basil lockwood -goose ex aviation engineer -his last working project was concorde braking leader of the 6 man build group yes it was one of the first Europas to be home built I got permission to do instrument approachs and touch +go,s --without touching down -- on west freugh when i did my IMC rating training on a c182 I had use of ,as it was closest place that had someone to direct approach right to ground level by radio/radar --think it was good for them for training as well. I had to wear "foggles" --which stop you seeing anything but instruments--to simulate full INSTRUMENT CONDITIONS and full aircraft instrument failure . ,turn +slip all covered up ,all you got is rpm and altimeter and compass all good fun

as i said above there will be sod all compression really to worry about

I agree if there were no other areas taking the load --then yes too small --but you already have found it only compresses very small amount -so the full load will never end up on any one area ,but shared and anyway i am assuming you have at least 6 other fixing at sides of window which will all take some load , so total downward force will be nothing like full weight this cannot be the first time this has been done what is normal solution ? I have used 2 lumps of 5" phonelic roof insulation as packing blocks under truck wheel s to get it 10" off ground -- to give space to get under easy and even with that very small foot print a tyre gives it dented very little even though there would 350 -450kg on each of rear wheels i think you are over thinking this problem really . but if want to make something tough then use expoxy lay up resin on grp woven cloth and lay it directly on the eps in the window holes -- expoxy resin will not melt EPS as normal grp resin would thats what i used to make the wings for the europa aircraft -- blue foam cores covered inexpoxy resin+cloth

450kg of window --how big is it ? thats one mother on a window ----sounds more like bi-folders than window but no problem just put a row of them to spread load --

heres a suggestion if you going to sit it on the PIR which is no doubt on top of an ICF wall? then how about putting a couple of support screws into the concrete and have them just flush with pir --then if weight gets too much load will transfer i doubt the thermal bridge it could possibly make surrounded by pir is even calculable --but no sinkage

I can tell you ,but really that is of no importance --the fact that energy costs dropped by£1000 is the important bit I had a £1500 lpg bill and when i dumped it my electricity costs went up by £500 -you can,t have abetter comparison than that .,as no other changes were made to the house or its heating system . no fancy calculations just real money costs even if you say my lpg system was rubbish --then you still cannot get round cost to use ashp on a late 70,s tf house --nothing like passiv is£500 for full year in scotland .
