use nexgen panels on the ceiling .????? that might be a good use for them in this instance

or stick welding is very difficult on thin sections like car body work --so is never used for anything but heavy gauge welding ,like bridges --over 8mm usually you can do a single pass 6mm weld or more with a mig machine TIG you can weld fag paper thickness ,,when you get good at it --much slower than mig +stick years ago I bought a miller syncrho wave 375 amp tig unit --to make alloy inlet manifolds where the flange was 12mm and could do it in one pass and can also with dif torch weld 0.5mm alloy --on a good day -- also had a alloy mig machine to make alloy car transporter bodies --but alloy mig is not very flexible and must be used with a push +pull wire feed or a spool on gun. modern invertor units for small sizes are very cheap now most of the jobs people bring me for alloy welding are wanting miracles --alloy sumps or very thin alloy casings in many pieces - not a problem if they want to make a jig to bolt all the bits in place while i weld and cool them or an alloy cylinder head that corroded to buggery --again not a problem --but after i grind all the oxide out ,then weld it up and themput on the miller to machine the face back true not just a 10mins job -- the thing they don,t understand is that to alloy weld the whole article to be welded must be preheated to over 200c -- best one i did was head fromn a 1925 rolls royce --,basically cast iron head --+old age and no antifreeze not another one on the planet --he tells me --can you fix it -- yes but it was not quick or cheap

being fairly fluent in both tig +mig the question is do you need to weld alluminium or s/s ? if so then tig s only really way and that is only good if you are working with NEW metal -not rusty things mig is generally far handier +easier for general purpose welding. stick welding is not as flexible or easy If you are contemplating welding up your land rover chassis --and you are keeping it --then don,t just buy a galvanised complete chassis unit and swop everything over -do it once do it right for a mechanic who has done one before its about 20-30 hrs - but very simple work with new chassis on oil blocks next to old vehicle on blocks --unbolt the bodywork --leave to one side then just swop everything over I,ve been here before repairing out riggers , patching up chassis legs then its a complete back end section --you just keep chasing it around and its still a rust bucket get a new chassis unit --fit +forget

you need harry potter and his magic wand then

I am still awaiting the answer to my question 130sqm house with near passiv insulation levels heat load of 2400kw per year why should i use nexgen instead of UFH and more importantly what would the cost of a system with controls to do this and total electricity required to accomplish an ambient temp in house of 22c can it use a mix of solar pv and mains as power supply for winter when solar pv cannot provide enough energy to run the nexgen panels you say it is fitted like wallpaper --that means it is not behind the wall but on the habitable side of it ,so would need to be covered by something ? do you have an installation video ?

Ok make your case for using nexgen instead of wet UFH heating in a NEAR to passiv house 130sqm heating load calculates out at 2400kw per year . I would like not to have spend loads of money on an a ASHP and UFh heating system and possibly run it from solar PV and switch to mains when not enough PV inthe darkest part of the winter and at night

nope -he is just using his certification as a method to get payment for getting the certification he needs to allow you to claim RHI although to be fair it will have cost him a fair bit to get that certification , his involvement in the RHI process is a couple of hours of paper work and maybe the cost of an epc survey at start to work out how much rhi grant you will get back .

having looked at the survey lots of questions -but its only really about being eco friendly - I question wold give same answer the survey is looking for are you a tree hugger ? and the answer everyone will give is -- yes if it cost me less to build the house and run it so YES to government grants will accomplish all that the survey is trying to get an answer to maybe sottish government should give a grant to farmers to sell the wool for insulation , thats as sustainable as you can get and process it in scotland --more jobs in sustainable industry the price they get per fleece 0.50p is less than it cost them to get it shawn from sheep ,or so i,m told by sheep farmers without the grants it will be build and running costs that are the driving factor in builders choices that is my view anyway

you have to think there are some bobby traps in scaling this system up ,or it would made for large buildings etc purely on energy savings grounds Iam thinking it would end up much larger than a std air con unit which would lend itself to industrial applications and not domestic

I like many are trying to find plot and funding and get PP -- what ever you get from this survey will not be tackling the main problem to house building in scotland which is the planning they work on the premise that they will always say NO to anything and you have to prove its a good idea If and when they turn that around , and they or neighbours, need to show a valid reason why you should not build in a certain location ,then you will see self and professional building take off which will help the economy in most of rural scotland dramatically in the countryside you have farming and forestry - everything else is a service industry to them in some shape or form an a active increase in building would stimulate the economy of so many small rural communities which in turn would help with the taxtion funds to provide more services for the whole community as it is if its not in central belt neither edinburgh or west minster will spend money onsrvices--so lets make these ares more economicaly viable --that means more houses and business

thats the point --when i was going to sell current house i was told to remove solar thermal panels ,as it would reduce value of house??? cos people worry about complicated systems with that mentality coming from estate agents ,which has to born out by experience what chance I know of someone who got 20k knocked of a house price cos it had solar pv on roof and deemed it was as a problem and could maybe cause roof leaks and was advised by estate agent to ask for the discount because it had solar PV on roof --

having done what you are proposing -close to 20 years ago yes fitting rads will be simpler -no argument does what you propose to do work -- absolutely YES but what are your parameters of this change --cheapest system to install or different comfort level -cheapest to run simplest way is to fit on top of floor you have now -you can get a system which will only add 50mm to floor height how well insulated is the fabric of the house ?- that should ALWAYS be first thing to address what don,t you like about system you have now --cost to run or rads blocking walls ?

If houses were like every other thing you buy EG it gets old and worn out --so it drops in value then it would be simple and viable to replace it I don,t see that ever happening you could always just move out of this hot dessert climate to more temperate areas ?

Its simple the s/e can buy water from the new independant country of Scotland .LOL and improve and use canal system to transport it down to them seriously though its time the money grabbing water authorities in england started to invest ,like the victorians did, in new reservoirs etc and not just keep trying to suck it out of the ground and rivers . plenty of scope with the wealth of the S/E to pay for it lets face it is a different country down really you only have to look at spending on transport compared to other regions . Or maybe just stop building more houses + commercial property down there and spread it over the whole country ? that would solve a host of problems at the same time

thats looks like @JSHarris next project looks like it could all be run off PV +solar thermal .

If you going to leave it over the winter don,t forget to add antifreeze to pipes or blow them out dry , if it will see freezing temps

at your age you have lots of time to find a plot jump through the planning hoops and then save and build it a bit at a time with no mortgage I,m 67 and i have a time problem ,as well as the money problems but i,m trying to get the right plot -lots of disappointments so far --but you have to keep the faith and press on 10years time full off grid with solar maybe be very possible and not have to live like a hermit

why sounds like you already have a perfect seal for the dpc+raydon barrier --juts fill with concrete- 10 minute job or builders foam as you would have sealed around the services you were going to run though them or combination of both foam in the middle with concrete plug each en --then you can always open it up again if find you need another penetration for something

you don,t have send lift right to the top - you wanna buy a good 2 poster --? a hoffman --none of this italian crap --a good german one screw type so no extra height needed on post height which will be about 7ft

don,t make sense not to put correct founds in now for later work -they cannot argue --you are just being super sure your wooden garage won,t sink

just for a laugh iasked for ringback from nexgen tied him in knots inabout 5 mins +said thank you and goodbye simple questions like how much to supply complete system for a house of 130sqm +2000kw heat load cost of equipment-- waffled on about choice of themostat and control system I said you quote for what you would fit -- then he waffled some more and i said BYe bye the only price i got from him was 600w for a room would require 2 sqm of foil @£35 sq m +control system -thats when he started to waffle when i asked for costs of control system and idid ask to speak to a technical person he also maintains that thier type of IR is 20% better than wire type heating panels and best place to fit it was in the walls as you get better IR to rather than heating under of furniture and carpet +it don,t really like cermaic tiles. and as i will be using cermaic tiles that was the final thing for me

I take everything people say as being correct -so there is a definite mis match between what you are saying and @TerryE the question is why the mismatch ? do not take offence if it questioned--there may there is a reason ,no one is being accused of varnishing the truth I am not a ludite in these things and continue to question and try to find improvements over what has been done in past and look to future If we believe what governments are saying then electric power of some sort is the way we are heading --quite quickly

day time --thats when PV is at its best and thats where the battery storage comes in for the PV-sell nothing back to grid probably house cooling at night --not really a problem if well insulated I have been living with a UFH system that has no slab for years and idon,t see it as big problem as you infer -especially with mega insulated house

I agree --but even a willis heater is the same ,just its transferring it to water ,which is then pumped around . I was postulating on @TerryE using his willis to good effect ,but it seems he also has a ASHP cost of UFHsystem --and then to run with electric -what are the total costs-verus all electric of some sort and on the assumption his figures are correct £10 extra for winter weeks only by using willis --,then cut out cost of complicated UFH system --could be geting closer than you think in running costs to go full elctric element in a near passiv house. big difference is you are not using a "thermal mass " to store it over night , and the shoulder months when you all complain about overheating --that would not be the same problem and floor would not absorb and store heat from passiv solar input ,so maybe cut down on need for air con ? and being quick reacting you only heat when you want it -no hysteresis problems or much less of a problem

various types coming on the market ,but basically a film type of heating panel that can be underfloor or in the wall of ceiling ,and are promising more heat for same input --less loss in transmission and can run direct from dc -or with transformer from mains . so maybe good for off grid applications with pv+batteries only+passiv type house ? http://nexgenheating.com/home/
