and thats sexist --i could be LGBT LOL

you mean you do not have to fit "dwangs" as they call them up here ,or noggins as they say in england

whats the attraction of them if they are more expensive?

but if thats what they ask for ,then are just plain wrong ,the whole point is to stop radon gas building up --so if membrane is in right place no need for a sump or anything else . rolling over to thier wrong decisions will make them even worse dictators

well i think dumfries & galloway can take that title here is a recent decison on a brick garage a man wanted to build on his own ground . house is within 30yards of river and garage had to placed slightly infront and to the side of house . then they changed thier mind and said no garage cos the footprint of garage would cause a rise in the water level when river was in flood !!!!!. now the river has never EVER been up that far to start with ,if it did the main street would all be flooded.to about 4ft so what was thier work around --fit 6 air bricks in bottom of garage exactly at floor height ,so if it did flood the water would come in and then run out again . now a 8x4 garage --will make sod all difference to river hieght if it did flood cos river by this time would be 10-15ft above normal level and twice as wide . beat that for stupidity if you can

thats why I asked if he was forced --cos they limit space under houses here --don,t like you having an area where the gas can build up ,which is a bugger cos who wants a crawl space under house --you want to be able to sit up at least . If i put that sump under new house here they would want a fan on a timer to purge it if you got they nasty BC man on a bad day lots you can,t even crawl under

were you foreced to have the raydon sump? i don,t see any purpose for it if you have a barrier under the whole house. theres no where for it to gather up in the foundations the way you have your barrier - .personally left to my own devices i would have put it below everything next to the compoacted sub soil and wrapped it round your nice insulated raft. the worry with old type founds was it would gather up below the suspended floor .or at least thats how i understood it round here its all granite anyway

https://econekt.co.uk/wp-content/uploads/2016/02/ECONEKT.-ICF-Elements-Brochure2.pdf see page 23 --concrete funnel is available as an accessory . isodom also loks like good system -- certainly the system with the most different types of panels I hyave found from roof to foundations

wee suggestion . now you have basically sorted the 50% threshold problem .all be it a work around maybe some data logging to see if you do indeed continue to put heat in and raise pcm well above the normal cut off point ,do you get more heat loss and therefore not good use of extra excess pv? fitting more in cascade mode to always have capacity will increase capitol cost HOW many years then before it gets to pay back point ..

that,s to stop the lids bulging .LOL

thank you --that is my point -get it sorted before causing war

you just proved my point-- and saying you been there twice makes it even more important to find out the truth before doing anything. and if your title plan is not correct --then maybe now is the time to get that sorted you need to get this sorted out before declaring war on next door . by digging trenchs like the somme doing what others are suggesting could end up costing thousnads in legal fees if next door do ont agree with the boundary line

you better be certain where the boundaries are on the deeds I would be getting copy of land title and talking to your legal man before doing anything If you weaken the ground and cause them subsidence --you will be paying in scotland you cannot build anything with 1 m of boundary anyway

after a visit from sepa and sub soil ground testing --they would then tell you how many hundreds of tons of soil you would have to remove ,send to hazardous waste dump then replace with new soil -- but not before SEPA come back and agree you have removed enough . If not off you go again friend of mine had a petrol station --the tanker driver over filled one of his tanks by 4000litre many years ago --it ran off the forecourt and into gardens of houses behind . he sold the site to a major oil company .--at that time they did not insist on a ground survey --as in drilling holes down to 10m --if possible --and getting the cores checked for contamintaion. some years later this oil company wanted to sell the site -- buyer came along --wanted soil test ,which was done and the history of the spillage was known by local petrolium officer . site had a resale value of 3m--end result the site was then offered for free,providing who ever took it on accepted responsibility for clean up --as the cost to clean up the poisoned ground was estimated at 2m . so far the major oil company are still running it--but dare not open ground up to do any up grades ,cos that would trigger SEPA insisting on clean up . the big killer is that any pollution found in a ground test is down to who ever made the pollution if they are still in exsistance. the polluter pays !!!. so very important that when you sell anywhere that your legal guy includes that the new owner takes on any liability for pollution . A local couple found some land next to river --no owner could be traced after lots of searchs.so they bought it from goverment ,took out insurance in case a relative turned to claim it. thought they had done every thing right. problem was that neither council or solicitor checked to see what had been on that ground before so 3 years on and new house built --family getting sick. turns out there was a tannery+ horse knacker yard on that ground in the 1700.s, right next to the river they were growing own veg etc!!. scyanide +other nasties from tanning process found in ground so ok no one died ,all better now --but it just shows how careful and how you need to check the old OS maps you can find if looking at new ground. so house is still there --but a dull chance of selling it. so council started getting worried then and did core samples along the river bank --and found pollution around another 6 old cottages next to this ground . councils solution --dig out the gardens and concrete them over!! that took about a year to do. this is why you see so many old petrol stations not re-delevoped .possible cost of cleaning up the ground before you start--bore hole testing etc usually cost about 5-10k depending on ground SO BUYER BEWARE ON BROWNFIELD SITES --even in the country

durisol uses PIR insulation in their blocks . look at the different insulation values of the different types of foam .and you will then see the differences in thickness you need of a lesser foam to get same insulation value as PIR

our strap it out and get service void as well? an extra layer of insulation ,maybe but also another layer to smoooth any temp changes and maybe simpler service fitting any sort of plaster will increase insulation

shoot me down if you like but why are you putting first joist so close to end wall. spacing is 400mm I read . so why not use some of you old wall plate,as i believe you replaced the old ones cos they were too short for those hangers to add to end walls so floor can sit on them --then move first joist away from end wall bit more --then do your 400 centres plenty of space to swing a hammer then

LOL --especially the irish ones

I have not started my build yet --will middle of next year I,m guessing Do I think it wll have a great effect if we have a proper brexit to start with maybe . will it affect house prices --maybe in SE --but not in most of uk where they have not had the silly house price rises over the last few years . I just bought 2 house plots over looking the sea for £60k each each is just over an acre --so no only see it being a problem in SE -- building materials --if house prices drop --then the suppliers will need to sharpen the prices as there will be less slaes to go round so it could make for drops in material prices--ANYBODIES GUESS till it has happened and dust settled . It is probabe that if we do leave interest rates will go up -- that will suit alot of people with pension funds and could maybe help the home build market again its all project fear until it happens do not underestimate the effect Uk leaving will have on EU suppliers as well --they need our sales one thing for sure --they are not making any more land ,time marchs on and we are all getting older and politicans always lie and the media is always full of fake news and promote the worst effects of anything .

one thing i have learned for sure over 40 years of being in the motortrade running dealerships and something i used to tell all my staff "how do know if the customer is lying ?--his lips are moving "

first ones didnt, have that sort of back up --it makes sense to not tell the driver the REAL battery states as customers will always ignore things unless the onbaord elctronics control what they can do --as you suggest sunamp will be doing the same with the 50% charge limit.

I certainly feel that if sunamp made a statement as to why you cannot do what you want and the technical reason why it would actaully make people much happier and knowing there is technical reason why would then be accepted by most ,especailly fi they said it will shorten the life of the unit Just like the EV cars --everyone now knows ideally you do not keep charging them up to 100% or let them drop below 20% ,cos it will shorten battery life

If it is as you suggest that there are lumps of solid in the liquid ,then that probably why they don,t want it be charged untill it s below this 50% level ,so you don,t end up locally heating the fluid too much and at worst case end up with some liquid close to changing state to a gas with solid lumps which have not managed to absorb the heat from the liquid parts quick enough . and the latent heat could cause that ,as all materials have a latent heat range where you need to put alot of energy in to make them changetemperature + state Ice has a larger volume than water ,then as you cool it even more it shrinks ,now not sure how much of this is to do with "free gases " in the ice ,but if same occurs in this medium ,then theres your reason for bulging cases, and we all know that ice can split pipes + rock . So possibly the cases are just not large enough to accomodate these possible situations of excessive localised heating from an immersion heater + solution is just make more space in the case ? do the first type of sunamp units have same case problems? I am not slagging the unit --just trying to get a handle on how it works and its limitations

stupid question about how thisPCM actually works is it a reversable chemical reaction or purely like water freezing and and melting and if the former how does it decide to stop if its the later then i am guessing it is a latent heat situation and the energy you have taken lowers the temperature of the whole mass and stabalizes the temp once heat has stopped being removed through the whole mass ,or is it lots of seperate cells .like batteries where some are discharged and some still full if you did not have them all directly connected to each other in series

and what issues would they be ?- -seem to have got a pretty good system --simple to erect ,very little bracing needed --a continuos concrete wall --no durisol webs which mean the whole thing needs rendering to make it air tight the panels look far denser than durisol as well ,I tried nailing a couple of durisol blocks together and it just broke bits off and no grip what so ever in the blocks . .sample blocks from durisol no it does look good
