I can understand using polished concrete for a floor, but what is the advantage for smaller areas like counter tops and around showers? I must be easier to get a professional to knock up something from a suitable stone in his workshop.

The rates are here: http://www.icax.co.uk/Renewable_Heat_Incentive_tariff_tables.html Have you looked into becoming your own RHI/MCS installer. The company I worked for fitted a PV system to the bosses house to get accreditation. Was not that costly, and I seem to remember that the cost for an RHI cert was not too much (arond 700 quid). It was 5 years ago, so things may have changed.

That was my thinking at first, it really comes down to the design I think.

And then this: Money, get away Get a good job with good pay and you're okay Money, it's a gas Grab that cash with both hands and make a stash New car, caviar, four star daydream Think I'll buy me a football team Money, get back I'm all right Jack keep your hands off of my stack Money, it's a hit Don't give me that do goody good bullshit I'm in the high-fidelity first class traveling set And I think I need a Lear jet Money, it's a crime Share it fairly but don't take a slice of my pie Money, so they say Is the root of all evil today But if you ask for a raise it's no surprise That they're giving none away Away, away, way (Away, away, away, away) Songwriters GOAPELE K.

Mafaldina There must be a wealth of knowledge down here about sewage treatment plants as there are loads fitted. Such a shame that there is no way of easily getting the info. Ian I am sure you meant to say the air pump should be in a building, not in the house. If in the house, it will suck out the warm air (which may help digestion) and play havoc with the MVHR, I don't know much about these units (just used to see Klargesters units a lot when I lived in Aylesbury), but I suspect that there is a lot of nonsense said in the brochures. They basically work by agitating and aerating the sewage. So bubble size should not make any difference (within reason) as it is the total energy needed, not the instantaneous energy. So a simple timer is probably all you need to 'clean' each 'batch', think of it as a multiple batch process rather than a continuous process. So air volume x time is the important metric rather than bubble size, which is a proxy for surface area (small bubble, greater area, but less energy). Keeps as many things that have to be changed out of the ground (so all pumps, gears, switchgear in 'the shed). As for shape, spherical or conical, this may make a difference for smaller volumes. Just a case of knowing the sizes and volumes. A sphere will have a greater top surface area than a cone for any given height, volume or in this case, the mass of waste in it.

When you try and put a value on anything, you need to ask a few counter questions. So, taking a subject that I know about, beaches, you could ask: How much should I pay to use that beach? How much should I be paid to not have access to that beach? Would others be willing to pay more, or less, for what I currently get for free? Same with planning: If you object to a planning application, are you willing to be compensated, or even by the plot, or move out of the area. You can easily put a price on any of those. So ask yourself the counter factual, which you have done, then put a cash price on them. So say you don't know about loft conversions, but you do know what premium they can support locally. You also know how much you are willing to spend on getting a conversion. Take one from the other, then decide if it can be done within that price. That will tell you if an 'expert' is offering value. X is the unknown factor, spurt is a drip under pressure.

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.
