I know, I have eaten there, was alright.

Call these people up and ask what they use. https://longfield.cylex-uk.co.uk/company/mahatma-cote-restaurant-18733887.html

Got eyelets, will travel.

Can you still tie your victims to them?

With a proper British Bulldog.

Floordrobe is best.

TV, isn't that short for transvestite. Cool, hope it has a built in webcam for those all import Zoom calls. I like this one, could watch all of Farage's speeches and feel very patriotic. I hope that is not a foreign plant in the corner.

Heating (and cooling) is not linear. As the store temperature rises, so do the thermal losses. This means that there is less power difference (set by T0 - T1) on the input side, and the transfer area, which is fixed. T=Tₐ-Ce⁻ᵏᵗ

Would need to thermally model it, then statistically model it in the thermo-temporal domain, then verify against the alternative configurations. But would probably be faster to just swap any pipes around.

I used to work in the health and leisure industry as a manufacturer and installer. We did everything except swimming pools. There were reasons for that.

Now go back and see what capacity factors I was comparing, before you get all high and mighty.

To building regs minimum or better?

Have you got your self build Community Infrastructure Levy exception in place (if your local authority has one). Cooling a building is the same as heating one. Work out the heat gains and the temperature differences, and that is the size of system needed. The rest is detail, i.e. condensation risk, slab or forced air.

Are you just restating what I said? Numbers are for the feeble minded remember, you can sort all the worlds problems out with words and made up scenarios if it suits you beliefs better.

That is just mothballed, there will be some on standby, either at spinning reserve or hot spinning reserve, so not so bad. We could also, if need, convert some old coal fired places, that have not been fully decommissioned yet, to biomass. There is also a lot of standby diesel generation. But a word of caution. That is installed capacity, not generation, so not directly comparable to nuclear, which has a very good capacity factor. A GW of nuclear is probably worth 2 GW of wind, to be on the safe side.

Should really convert that to kilograms, then it is pressure and temperature independent. PV/T =C

There are three aspects to how the air part of an ASHP work. One is the relative difference between the cold side of the HP and the external air. Two is the amount of air moved. Three is the chances of the external radiator frosting/freezing up, that is related to humidity. The amount of specific energy in air is pretty fixed at the temperatures they work at in the UK (there is a slight drop as the temperature drops, but not much, about 0.8PPM over 60K https://www.engineeringtoolbox.com/air-specific-heat-capacity-d_705.html). What can happen is the if the ASHP is running at close to full capacity when highly water saturated air hits the cold side, it can freeze, this both impedes the airflow and insulated the fins. This is why there is a defrost system built in. This uses little energy in the scheme of things, so not worth worrying about in a correctly sized system. The most likely temperature to cause freezing is not 0°C (273.2K), but ~4°C as this is when water is at its most dense, so there is more to condense out than at 0°C or below. As @Iceverge points out, they shift a lot of air, so location i.e. sun or shade, makes no real difference. Fit them where there is good airflow and the external pipework/wiring is short. Don't try to run an ASHP at its highest rated temperature, that is like driving a car at top speed all the time, it will end in problems (I suspect a gas or oil boiler would break, if it was run 24/7 at full rated power, fairly quickly). If you get into calculating thermal efficiencies, they stop using the celsius scale and use the kelvin scale, the kelvin scale is a truer model of the kinetic energy of air molecules, and there is no minus temperatures to fool you.

I am very impressed with my Russell Hobbs one. RH601H401B. I did not do too much research, just landed lucky. was one of the cheapest from AO as well. Yes it is. Was from Aldi. I went into the store to buy one for my boss, they did not have any there. Asked and they said they come and go, so still made, just not on the shelves at the moment.

Come back in 4 to 5 years time and show us you were right. Otherwise you are talking horseshit.

But PV can produce effective power for a greater part of the year, and in lower light levels.

It is too fa from the sea to get a proper view.

They do, in a general sense. If I sell a family a meal for £100, that is £100 less they have to spend on 'other things'. Those other things may be the same thing I spend on, or may not. We are currently awash with cash because of low interest rates, QE and the furlough scheme. Inflation is, or more likely stagflation, is probably going to happen, what we are currently seeing may be the start of this, something that we have not seen for 2 decades. My point is, both customers and supplier should be aware of this and not let it become a shock. We want to avoid a dead cat bounce, which may be what is currently happening. On Nick's point about customers being in too deep (for some reason I cannot quote). How much of this is to do with the knowledge imbalance between the lay person (the customer) and the professional. This is one area where we need to educate the general public to not trust a contractor to do as they say, at the price they agree upon. We really need a new topic on this and point all new, hopeful, self builders to it. May save them thousands. As a friend of mine once said, 'don't do something if you are no good at it'.

We put up our prices before the headlines started (some of us remember the late 1970s). We anticipated three things. General price increases, increased footfall and lack of supply (we knew that as our suppliers warned us a year ago). We also reduced our menu options and allowed for more flexibility. So if a relatively small cafe (in the scheme of things, though it is large for the area) can cope, and we have coped (two all time record breaking weeks at both the places I work), then I fail to see how other professions cannot have done the same. There is a difference between being proactive and reactive. That seems to be my criticism of the building industry, along with being too reactive. If one enters into a project during times of turmoil, then plan for the worse and hope for the best, and have access to cash at all times. As Jack pointed out at the beginning, and Ferdinand restated, get the contract right at the start, not hope to change it halfway though. If the builder is not willing to work on a firm price, then they are not the builder you want. If you cannot afford the price, or the extended time to finish the project, then reassess the project. I think the real problem is that there is too much emotional investment in our homes, this clouds judgement way too much and we expect the trades to have the same enthusiasm for the project. Now that is a logical fallacy.

Gas, nuclear and petroleum have also gone down. It certainly looks like total primary energy as it is in Mtoe. 1 Mtoe is 11.630 TWh
