That youtube video was more fun than watching a murder or two on Endeavour.

No, just dry and flaking.

Yes. That was it. Think I have one in my apprenticeship toolbox that moves around with me, but never gets opened. It is in the loft with my portrait painting.

Just to misquote The Pussycat Dolls. These pictures are an hour and ten minutes apart. First one was after 5 days away with no heating on. Just my hot bod warming the place up.

I am sure there is a strange looking file called a rifling file, kind of pointed, 3 side and curved at the end.

That makes the roof important. Also makes the design simpler.

It is nearly New Years Eve, not 1st April.

You are right. Some of us on here have already done the easy savings. The general population is entirely different. As a slightly different example, because I am driving 600 extra miles every week, I have decided to put my 40 year old automotive engineering skills to some practical use. If I drive normally on the A30, M5, M4 and A34, then A40, I get about 45 MPG. If I potter along and add an extra hour and a half to the journey, I can get 70 MPG. Now I appreciate this is not a house, but expecting a little less can save a decent amount (about 40 quid a trip). My biggest energy saving device is the Poundland washing line.

That is mixing up media and craft skills with artistic skills, and neither are engineering, which house designing is. Many artistic painters work from photographs. That does not make them IT specialists.

Would these be the wankers that do initial sketches with pencils. And that is only because swan feather quills are harder to come by.

Most people could easily cut usage by 30%. Long term historic prices have been 5% of median household income.

Been told that they require a mobile phone signal for data transfer. Also been told that the E7 radio signal is being turned off in March, but probably won't happen 'because of COVID'. EDF arranged to change my meter, 2 years ago, they failed to turn up. Still waiting for a new date. Get really excited when they send emails about it. But they are just round robbin ones telling me that all my power will be free, and I get to use the chairman's daughter. At 24p and 14p a kWh, I would be round like a shot fitting them.

A new ST panel in the making Did you download that from the dark web, looks like a gun.

Don't forget J and K

Anyone done a similar test on solid state relays? Print this out and keep in back pocket.

Seems a simple way to control it. It should stop the HP doing something that is impossible, i.e. reach a fixed output temperature when the input temperature is extremely low.

Is that how your HP controls temperature by keeping the pressure within fixed limits? PV/T = C and all that.

Just done a quick chart about a heating curve. Assumed 3 different power levels, half power, ideal power and double power, the numbers are for reference and not actual power. Because heating starts rapidly, then slows, for any power input, it should be possible to initially run a heat source at lower power for a set time, then ramp up power later on. This could be useful if using PV to supplement the grid supply as it would reduce imports. It may also be useful to reduce cycling and frosting.

I misread that with an N in it.

I think you get caught with unexpected employment law and taxes, i.e. you have to pay minimum wage. Self builders are except from CIL, but companies are not. Think the VAT is different as well.

Or build that first, on a crushed brick foundation. Then move into the 'shed'.

Energy is sold by the half hour block, but it is sold usually the day before, though there are long term contracts (CfD and so forth). The generation companies need to know that they can supply the energy that they have sold, or they have to buy from companies that have excess. When they buy in at short notice, it costs them dear. So it is not as simple as Net Metering, as it was called before the FiTs came along. When only half a dozen 'hippies' like our @DamonHD had installed PV, it did not matter what they got paid, or not paid, their cumulative generation was tiny, not enough to affect even the local grid, let alone the national one. It has to be remembered that the FiTs and the RHI, were set up to encourage the domestic RE sector to expand, not to purely reward householders. That was where the big mistake was made, and how we got into this nonsense about pay back times and amounts. Having said that, it did massively expand the sector, you can't fail to see how many plumbers and electricians have 'Renewables' sign written on their vans. I think one of the mistakes made was not allowing the local DNO's to administer connections i.e. a dynamic list that shows what can be connected and where. We got into a state where a street can have multiple micro generation installations that cause local problems, and the DNOs are expected to sort it out. Though we got caught when we installed 16 kWp on 4 properties in the same street. The DNO sent us a bill for a few thousand for a new transformer and cabling.

Trips to the tip will cost you about £2/50lt bag. SITA are thieving bastards, but then so where BIFFA. But I think they are now SUEZ.

This is a very important point. You will almost certainly find that the good trades are booked up and expensive. But having said that, some TF companies will arrange to do most of the initial work, and that is where the important thermal details are achieved. Apart from the nonsense about 'thermal mass', and we have loads of debates about it and the zombie refuses to die, all you are trying to achieve is an airtight box with low thermal conductivity. Not hard to achieve intellectually, just that detail and longevity of material interfaces can ruin it. Having said that, the Space Station has been floating about (actually constantly accelerating) for nearly a quarter of a century, and they keep adding extensions to it, but not by Bob the Builder.
