from my experience changing from LPG to an ASHP --with no other changes to heating system was a saving of £1000 a year LPG should be your last option

yes i,m looking at one that was last occupied in 1965-has full walls but nothing else - so this would be treated same as a new build then ,even if i did not flatten but rebuild it ?

5% is alot different than 20% though maybe iam picking you up wrong you are saying that 5% will apply ,but you can reclaim that so in effect it will be zero vat on materials to build ?

very rough calc would say 18cubic metres of something which would be approx 24 tote bags @£35 ? a bag ==£840 or a truck load --if you can get it direct to tip it in

ok next question ruin that has full walls -but nothing else and you are rebuilding basically as it was Do i understand correctly that there will not be full vat reclaim ,only 5 % If so then why would you not flatten and rebuild from scratch ?

well you have learned a lesson to more accurate we all have learned a lesson --hopefully from your troubles always cap any pipes or ducts never leave any open for something to make a home in

800mm block wall with 1200mm fence on top --no rot problem then and no weeds coming through ?

no one i have talked to is offering as short a time scale all 25 year lease

sounds like a real mine field we all know what happens with relations when there is a death and money so what about a deferred sale of this land at an agreed value now -payable to his estate on his death and you would need to get all siblings to sign up now to this agreement or there will be a contested will if it is preceived by the others that you have robbed them . If you think he will live more than 7 years then he can gift it too you --but same again you would want a legal doc that others sign to say they understand this time for some legal eagles

the more i dig into this storage idea the more it looks like it is only good if you can sell it not to the DNO but to a local company that has big power needs ,but if just pure grid smoothing then the rate drops dramatically --will post more when definitives are known . It seems a lot of solar PV farms have allowed for storage as well --but not doing it yet -as the 10-15year projected cycle of lithium cells will not make a profit as selling renewables are expected to drop in value So from what i can gleen from many sources it looks like they are waiting for "flow batteries " to develop a little more ,as they do not have a limited life span same as lithium so maybe when someone makes a smaller flow battery that might be the time to fit to domestic installation ? the fact that all these solar farms have allowed for batteries in design of farm ,but not fitted them would suggest the time is not right yet for battery storage --just use all you make to get best return but maybe BREXIT will change that as well . One company who is offering PPA deal told me its 15 years to get capitol costs back before they start to make money --if it is all just sold to DNO. so this backs up my calculations for the domestic system - -obviously not that much cheaper to do even when you talking about 30 acres +10mw than if you do a 4kw home system which makes me think we are close to minimum costs for panels now ,without some miracle breakthrough in production so unless FIT or something comes back then the domestic market will not grow very much --a pension fund can look at 25year term ,but not many private people will . I am not saying don,t do it --but to get your best return and payback quicker you got to use it all

bottom line is on a grp roof there will never be osmosis if it is rolled and compacted correctly .

use t+g boards meant for the job--not super cheap OSB --thats what proper grp roofers do+don,t forget to insulate the underside if it is likely to get condensation in the winter and if you must use 18mm osb -then drop a coat of resin on it to water proof it if not doing complete job in one day https://www.aboutroofing.com/18mm-osb3-tongue-and-groove.html read this this boarding has a resin coat already on it

there are companies that do that now you rent them some space to sit 40ft containers on.if you have a nice large supply close by these are huge battery packs +control gear--1mw each they buy electric when cheap -then sell back when the grid needs it to smooth out local power needs looking at a site now with that in mind - -the main thing is that your local grid has some spare capacity in it and you have local substation that is big enough to take the flow -- this seems to be the most usual problem for them not being able to do it,so I am told ,that and planning as they make a bit of a hum- If my primary discussions +rental rates are correct --then you could expect about £10k-15k an acre for 25 years -- could be a nice little earner for in the right place

end of life ?? you are refurbishing an old building --so when do you envisage the rebuilt building being flattened --another 200 years?-- hardly a good reason not to use best waterproofing solution for an old rubble wall

yes that looks like i was meaning thicker concrete where posts will sit I would expect that to be the case where ever the cook frame touchs foundations

12month is what i read - -so not the best time to start with Pv as we don,t know for sure what final scheme will be and so cannot work out payback period etc till rates are firmed up It will come --give it time ,by then maybe battery pricing will have changed as well

lookin at same sort of thing looking at building TF close to inside of wall then spraying inside of wall +behind TF with of closed cell foam to water proof it and fix outer wall with the closed cell foam then --fill it all with open cell foam (half the price of closed cell) and carry on as normal TF vcl -batons service void ,then PB wall at this time is 700mm thick so idea is to remove inside rubble wall leaving the outer cut granite wall + bond to TF --that will stop the rooms getting too small other idea is remove internal rubble wall ,still leave outer skin --then build 100mm block wall and again bond the 2 together with closed cell foam ,or maybe fill with concrete with water proof additive for the water proofing --then same TF with lots of insulation. but with this way you could make a ring beam with rebar at wall head to tie it all even better comments welcome

unless you are already on FIT system started before end of march ,then any new installations cannot get payment for energy that is returned back to grid . the new system ,as I understand it is called SEG and its not finalised yet and only a few test sites are being run and will need a smart meter so they can pay you at different rates dependant on what the spot price for electricity is at that time-it could change tariff every 30mins so trying to make some sense of it for a new installation is hard at this time

I had same situation when i was renovating my kitchen 22mm copper comes out of floor to stop tap behind sink I had already found the main feed before it goes under slab was poly, it was by the side where i dug my pond I suspect it was the builders temp water supply for house as it did not come in a direct line from the main "Toby " I could move the copper pipe around like it was moving on the compression fitting in the floor--so I did not like digging up concrete floor to find where it was loose--so ran new pipe I was lucky enough to be able to run a complete new one from toby into house through garage . the thought of laying a tile floor in kitchen then a year later it all leaks -- no ,no ,no, had to move it

In our area replacement of traditional long low houses with modern is not what they want -when bringing old house back into use -- so for all scotland like to shout about being eco friendly etc when it comes to building most efficient housing for footprint -they fall short

Or you could seal both ends and pump it up with compressed air and pop the dent out?

my ASHP is mounted on a garage roof and it is on the special sound absorbing mounting which looks like a big slab of concrete ,but is actually hard foam and noise is transmitted to inside of building --not a lot but as much as the sound when viewed from outside the building If you are putting it on a roof which is made from beams and osb etc --you will get noise transmitted through it If roof is concrete I,m sure it will be silent

my guess looking how much the frame of velux is showing there are no batons --just tiles nailed to sarking If it had been on cross batons then you would fit velux first,then batons round it and you would have a perfect finish

ok --don,t think any panel beater i know would try to get a dent out of a pipe 1 meter inside from end. heres how you do it gat a round piece of wood the correct dia for inside it make an internal taper on it from both ends split into 4 or 6 sections along its length make up two taper sections that can be used to force the segments outwards -thread one of them and you can use a rod to make them act like a wedge make 2 0r 3 grooves in the sections for elastic bands to hold it together while you slide it in --then expand it and push out the dent https://www.ebay.co.uk/i/113750110783 like this turn it on your lathe the right size

I would be more worried about the copper pipe which appears to be set in cement corrosion ? and where does that copper pipe connect to under ground?--one presumes its not to a lead main --so its probably to a plastic one with a compression fitting ? maybe time to make it all plastic underground to above ground . I would , while you are at it --and stop old age problems later with the supply
