Yes there is, could contributed to many in the past. There does seem to be a regular core of contributors that think data and fact are not important.

Why I said. Rather than zero.

Having been involved with catering for over 45 years, I still don't know what proper, real or fine food really is. Flavour and calories is all I care about.

Is Tom Foster still working with magic physics and Renewable John heating and powering a whole town with half a metre square of grassland? Shame that some people in here drove @Ed Davies to go back there.

Almost as big as my house footprint.

You ever watch Auf Wiedersehen, Pet, may have been World Class British Builders.

Make it part of their job, if they are any good they will be pleased to.

Sometimes I have them. Would there be any reason why you cannot parge both sides of the block as you go along? Wall ties may bet in the way, but they can be navigated with a hand brush. So something like build up 4 courses of block, parge, batten, cables/services, put right, put right, put right, insulate, put right, put right, put right, and then the visible finishes.

I don't think tape is a get out of jail card here. If you must build in leaky block, I would have thought that parging it as you go along is not going to slow you down any, may even work out easier and cheaper, less battle fatigue.

I found this, if it is any help. https://lignacite.co.uk/products/lignalite/ Seems they are around 9 m3.h-2.m-2 when untreated, so pretty poor.

That was only possible in the era of cheap energy. Still not found out when that was, 1980 I think.

That's entropy man.

The ASA has plenty to say about that as well.

Small claims court.

I find the same with my vented DHW. The loft F&E tank gets to over 20⁰C.

Yes. Then find there is not a lot in it. In reality, if you know the temperature of the refrigerant on the cold and hot sides, you can calculate the efficiency. But as both if those will be varying with OAT and delivery temperature, it does not help much. Using the kelvin scale is the better way to work out the potential energy available in the outside air, but then humidity levels can screw it up no end because around 273 K, water will stop condensing and start to change phase, and that release a different amount of energy. Also that water is at its most dense at 277 K. Confusing it more. It would be useful if there was easily accessible data, through a range of OAT and RHs, while delivering a range of temperatures and power. Kind of think that once written a spreadsheet is great for.

They will be snuffing your lights out. Worse than that, they will know when your mummy sends you to bed.

Stick it in place with this. https://www.toolden.co.uk/p/everbuild-evb5minpu3-lumberjack-5min-wood-adhesive-gel-310ml Just make sure it is in the right place.

283 [K] ÷ 293 [K] ×100 = 96.59% 10 [⁰C] ÷ 20 [⁰C] ×100 = 50% This gives the size of the numerator, with respect to the denominator, expressed as a percentage. The mean free path speed of the molecules, in an identical material, will be the same in both instances.

Do you mean Fischer? This is worth a read. Just one of many. https://www.asa.org.uk/rulings/fischer-future-heat-uk-ltd-A19-1033945.html

With the kelvin scale if you must show temperature increase as a percentage. But if you want to know the improvement in CoP the you look at the difference between the two electrical energy uses. Remember that temperature is not energy.

How much are you paying to get power at that time if day?

But only if you use the correct temperature scale. When calculating only the kelvin scale should be used, or you get the ridiculously saying 'it is twice as hot as yesterday' when it may only be 10⁰C warmer at 20⁰C.

Ah, the wonderwall of studwall. Or are you the wonder stud of wall banging?

But still no mobile signal in the valleys.
