walking round with a joss stick or small smoker -like for a bee hive might show you things if leaks are bad

spec sheet of wharthog https://en.wikipedia.org/wiki/Fairchild_Republic_A-10_Thunderbolt_II an aircraft i would like to have flown in real world sim games with were fun though

the "warthog " a10 thunderbolt carries 1500 rounds of this ammo --weighs 7 tons but is a great tank killer

thanks for that I know my electric bill for year at this house is around 9700kw --thats all energy input as i,m all electric ,including 24/7 pond pump outside lights etc in this house to be fair me and her like it 23c everywhere in house and it is running on theromstats 24/7,and probably hotter in years to come so anything I build close to passiv will be a major improvement and will suit me fine . I,m still unsure till I get final design what i will be building and with what system --but plenty of scope . I,d like to think I have enough money to do both plots --we will see as costs crystalize

everybody makes their own choices and as long as they are happy with them that's perfect and no one has the right to say their choice is not a valid one if it fulfills their design goals and aspirations

above the extra insulation . the noise reduction will be very good with insulated plaster board as i found out when refurbing this house and that was only 38mm screwed direct onto existing plasterboard on north and east walls (outside walls of that room)

I suppose if you are a "sunamp man " then you will not have long runs cos you will have a sunamp in each bathroom and not main hot storage

theres your answer then --hot only is requirement

would depend on flow through them ,as they will heat up if not flowing all the time

think that is a 30 year plan though -trees that drop leaves don,t grow as quick as christmas trees. but i suppose it depends how far away they are as to hieght required

I am already there ,at pension , and trying to sell off my last biz property and starting on self build .my views are similar to yours but tinged with --when i,m dead --do I give a crap about someone getting extra benefit from me going OTT on build spec ?,which will take 20 years to recoup I am thinking more of economical running costs .but leave enough cash to spend on going to far flung places my will should read "being of sound body and mind --I SPENT THE BLOODY LOT". and government can go whistle for inheritance tax if at all possible

as long as your mains pressure is good

If all are inside the hot envelope of house --then probably not worth the extra expense outside that then yes

hardly --that surely is the point we know better by now so we should not be making problems for the future that we don,t need to

and nuclear waste is still aradio actve substance ,except when it was in the gorund it was not so concetrated you want to eat some then ?,where you going to dump it ,who's picking up the tab for that Its exactly the same this disposable way of life cannot continue

no argument there , but is it really required --will only cost more to build and is the extra £10 or more per sqm (icf poly block ) really needed? lest say 150sqm of wall @!£10 sqm = £1500 . you would need to know extra fuel costs to know if its a good trade off. getting even cheaper heating cost gets more expensive --its the law of deminshing returns and if low anyway ? I,m not saying anybody is wrong going above passiv minimum ,so don,t jump on me , but as with all things ==there is always compromise

So maybe the answer to summer overheating if you want lots of floor to roof windows is coating on glass to cut down the amount ,not all of the solar gain it can give ,for a comfortable house

I,m sure they said that about nuclear waste as well-- It has not

ok so thats answered my questions 0.15 W/m².K for all walls ,floors and roof

only sensible option long term in scotland is a lot more hydro .either as pumped storage or simple hydro, or tidal races by building barrages on small bays where rivers enter sea. 2 tides a day --every day -which means 4 opportunities to turn turbines every day NOT nodding ducks or anything continually in sea water-- sea water eats everything global warming means MORE rain and as we are a maritime climate we just going to get warmer +wetter If they want to give us more FIT ,then that would work as well --but as it is now -only the few will engage with PV I just don,t see lithium batteries as any real solution ,not until they can recycle it cheaply , at this time very little or any of it is recycled ,cos its cheaper to use new and it is a finite resource we have dams that are nearly 100 years old which are still viable

ceramic tiled floor would be a good heat sink ,which is what i used on my suspended floor

yes, you are correct just checked manual for the one i have and temp range 65c --80c ,fine it was feeding a cylinder, then to UFh with thermostat ,but not direct coupled hard calculation ,but maybe if you had small thermal store --heated to 70c with economy 7 at night and then UFh uses it as required with thermostat through the day , but then you might as well go for simple immersion element on tank -- life is never simple

absolutely no argument there at all --,but has to a balancing factor . like the kingspan man told me when speccing insulation for my solar store anything over 6" of phonelic is probably too much cos extra cost verus extra insulation never works out. which is probably 10-12" of polystyrene as a comparsion .

last one i bought i got on ebay --unsed -bnib --at half price --so if going that way start goggling

the answer is adefinate --yes --but it might be very small --like in a combi boiler -if its going to run be a non vented system amptec type you get temp control etc all in one package--its what they were made for simple heating solution for a flat
