Yes, let your MVHR unit do the work. You do still get a 'biofilm' problem, usually called a scum line. So if you are worried about this, and the environment, then spend the money on a suitable cleaner.

I used to work for a PV installer. I really could not see the difference in modules, except for looks i.e. all black, no silver. Apart from damage, I have also not heard of a module failing. So discard the sales hype, go for the cheapest. This is also true from the different 'chemistries', there may well be a marginal improvement at certain light levels, but like a Porche on the M25, it is rare that you actually benefit from it. No matter the size, performance or price of a module, it will generate very little when it is a dark winters day.

Does SAP (TER/DER) use primary energy as a fuel source? If so, that could swing it as our electricity grid is getting less carbon intensive.

Then shop about for the HP you want, that could save you a fair bit.

Run the waste water though a W2WHP. That would cost even more.

Are you going for the RHI, that pushes the price of the install up.

Last year I went around Penwith taking pictures of ASHPs that are close to the sea (<100m). None seem to have suffered any serious affects. That could be because the ones that had are no longer there. I think the Mitsubishi ones were OK (Lidl in Penzance). A hunt around the old eBuild forum may find my pictures of them.

You can get the 1-Wire temp sensors pre-wired into a string. May be easier, quicker and in the end, cheaper to get some lengths of that. http://www.homechip.com/1-wire-controllers/sensors/t-string-temperature-sensors.html Have a word with these people, I have always found them helpful. https://www.homechip.com/

I got this yesterday, £15. It has to grow on a tree with a ten pound note to be so cheap.

Century before last looking at the um, styling, of Morgans. From the Forestry website.

Well I go the Titan TTB515STP from my local NailFix, seems to work well. Only £15 as well. I shall never use a screwdriver again. Thanks for the tips.

Not really. I had a mining survey done as I am in a mining area (not far from Mafaldina). But as I paid cash, and the house was only 18 years old, I decided to not worry about it. I thought that money lenders had to accept 'third party' insurance policies these days, assuming they have the right cover. It may be worth pointing out that no fracking is going to happen in Cornwall.

Yes?

I have a ScewUp near me, and I see they do one that takes 15mm nails, shall pop in and see if they have one, thanks.

Had a quick look at this: http://www.forestry.gov.uk/forestry/infd-7m2djr And it seems that prices are higher in the Spring, and that they increased a fair amount in 2014/15, but have dropped back again.

Thanks, shall see if I can find one locally to look at.

Do timber prices get adjusted because of the seasons. Just thinking that trees are currently growing and people are doing 'outside' building work.

I make a few St Ives picture frames for people. I am getting a bit fed up with bashing my finger tips when I put the panel pins in. These are small pins, no more than 25mm long and often 12mm long. Does anyone know of a very small, mains powered, nail gun that can do this for me? Ideally I would need to get into small corners with it, have the pins go about 2mm below the surface, and be able to get the pins easily and cheaply,

M = multifoil, unless you are a Freemat or MatLab programmer, that makes me sweat more than a hot chilli.

When I lived in Bucks, I had a house build for the USAF, built in the late 50's I think. It cost next to nothing to heat and had lots of glass. It was 'thermolite' cavity and brick. Strange how they knew how to knock them up cheaply and quickly back then, and now we ponce about for years to get a place built. Does your place have a wider than UK standard front door?

You going to let on who is selling it, is it someone we know? Then I shall ask the committee to ban you for mentioning the M word. I think a lifetime ban would be appropriate

I did pay good money for it, I still owe more on my student load than I borrowed. Oh how I wish I had been told that common sense and a bit of general reading could be converted into an Economics BSc, I would never have taken up engineering and Physics/Mathematics.

It is the lack of transactions at the bottom end of the market that is skewing the mean house value prices. There is also the point to be made that asset value is not income, so take someone that bought a £150,000 house in 1987, it is now worth around £800,000 if you take the mean national house price inflation figures, http://www.tradingeconomics.com/united-kingdom/housing-index They have not earned any cash from that property, have not had any dividends etc, but have had, in most cases, a lot of outgoings i.e. maintenance, mortgage, heating, insurance etc. So saying there is a lot of money at stake is not really correct. We could easily halve the value of housing in the UK, so take it back to around 2000 prices (when the IMF warned the UK that property was seriously overpriced) and it would not material affect the economy of the nation, though it would cause a few personal tragedies for those that have borrowed against property and/or over borrowed. But that group are probably in trouble anyway and they would still have halve their mortgage term to correct it. There would be an initial shock as the big investors hunted for other markets to invest in, but that could be a good thing, investing in fixed assets that only rely on sector inflation is a high risk strategy that can go seriously wrong, when it goes wrong. Our pension funds have still to recovered from the last two property slumps, and they still invest heavily in property.

If you look at my results you will see that the Max is showing 128, which it complete nonsense as water boils at 100. So I know I have a mistake.

In Excel you can highlight and get some quick answers down in the bottom right hand side. You can customise the results by right clicking. The real way to do it is to use double entry book keeping methods, but this is tedious to set up and involves more work. Main thing I do is to keep it simple. So I try and always use absolute referencing when I can (names ranges and the use of F4) and often use two different methods to get the same result i.e. Average and then Sum and divide. I still make many mistakes and can spend days looking for them. One of the classics is mixing up text and numerical values in a range. Of a simple decimal point out of place
