If only. EDF who I am with, estimate the amount based on average usage. Trouble is that it is not my average usage, but national average for a house that uses E7, so about 3 times what I use. I refuse to set up a direct debit with them as they once tried to bill me £2500, when that was refused by my bank because I did not have enough money in my account, they tried to bill me £1999, that was refused as well, then they tried £999 (refused). The amount owed was about £60, but I got left with £90 bank charges, which Santander refused to refund, and EDF said it was not their problem. I cancelled my direct debit and went to quarterly postal billing by cash/cheque , which is not available any more. This got changed to monetary billing, without any notification or warning. These energy companies just do what they like, and getting a proper resolution is time consuming and exhausting. Swapping provider, when you are a very low user, is not worth the effort.

It will leak air like a Wimpey Home, especially around the doors. When your husband got it, did the old mannequin get left behind.

Would one of those polyurethane roofing solutions work. Something like this: https://www.topseal.co.uk/polyurethane-roofing-system/

I think that is the problem. They can bill you, via DD any amount they like, then take ages sorting it out. Ask Bulb customers who had overpaid how long it took to sort it all out, about 18 months before Octopus took them over.

That is my view, except the checks on suppliers are much more stringent now. Who ultimately owns Tomato?

But still very informative. Curious Cases https://www.bbc.co.uk/sounds/play/m0024054

Yes, kind of, no. Just moving something that is hot says nothing about power transfer and the use of that energy. If, in the typical model, a wall mounted convection heater, moves some air up towards the ceiling, as it passes though heater, the air is warmed by radiative forces, then as it moves back into the room, it heats the room by radiative forces. It does come down to how small you slice the problem up, and the usage of language. Invection is a better term: introducing from an outside source. I am still not happy with my explanation on intensity and frequency.

Just replied on the the other thread about this. Much better to find other ways to reduce the primary usage, rather than use technology to reduce usage.

I really should check up on this again. I use less than 1 MWh/year on heating and about 1.6 MWh/year on DHW. I have never got the numbers to stack up, but it would give more flexibility on when I heat without a large price penalty i.e. difference between day and night rates as I am on E7. I have never been able to make fitting PV worthwhile, but that is really down to the roof not being large enough, and not facing the best ways.

Yes and no. Energy is transferred because it excites electrons to a higher orbital. The higher energy electrons want to return to their original, more stable, state, when they do, they emit a photon. That photon, which can be though of as a packet of pure energy i.e. massless, moves until it interacts with another electron, raising the electrons orbital, and then ceases to be (can be modelled as an 'at rest mass'). So while we like to think of thermal energy transfer as conduction, convection and radiation, it is really all radiation. It gets a bit more complicated as there is intensity and frequency, and I have never found a simple to understand explanation. The nearest I can get to, to explain intensity, is that depending on the material i.e. which elements, the strength of the bond between the electron(s) and the nucleus is different, so some materials take more, or less, energy to dislodge an electron i.e. different place on the electromagnetic spectrum. Then it is the number of photons, the frequency, that pass or change the electrons in the element, that governs the rate of transfer, the power if you like. There is no decent 'mechanical' description as it is a quantum problem, and as they say, 'if you understand quantum physics, you don't really understand quant physics'.

Yes. This is my favourite after thermal storage at point of delivery i.e. in my airing cupboard.

We could not get it through planning in that time. And then we could not connect it as local planning departments would not approve any new pylon routes, that join up. I think that we need an open register of people that disagree with RE development, then we can go around their houses and pull the main fuse. Maybe the energy suppliers can do this remotely. Sliding scale based on grid intensity, then grid intensity gets to 0 GM/MWh, then those people get no power. Or shall we just waste parliamentary time on killer the sick, rather than improve palliative care.

That is just this year though. One of the things to come out if this year's CoP was us westerners paying to install RE in smaller countries. Not going to happen, even though it is the cheapest way to help reduce atmospheric CO2e as their economies grow.

I think China added 210 GW.

A hydrogen generator is a fuel cell, so expensive metals and an ion exchange membrane. Then it needs pure, deionised water. Then water vapour needs removing from the gas. Then compressing. Then cooling. Then transfering into suitable containers at 700 psi. Then transporting. It is not like a school science lesson, that just heats the water up and releases tiny amounts of gases.

For me it is the mistakes we make, for builders, earning £300/day probably roast swan and panda.

Found a man that may be able to help, got the same name and initials as you. Knows a bit of chemistry. I shall shout your questions up to him after a leave the nearby Weatherspoons. Be interesting to see what the response is.

I wonder if a house could be designed so that every angle can be a right angle somewhere. That is a brilliant idea, did the builders use them as place mats when having luncheon.

Not as simple as power, a couple of wires and a bucket of water.

Only for right angles.

They are a peculiar species. Not human at all. Most seem to dress like Jimmy Savile as well.

it doesn't, the home battery will still not have saved any money.

Really, there is nothing special about a person when to comes to thermodynamics. That is better. It is an inverse square law, so double the distance from the heat source, you half the power transfer, why people crowd around a fire. Then there is the angle each direct beam of IR hits the object, at 30° half the energy goes somewhere else, and then gets worse as the angle increases. There is also the physiology of humans. We breath in air. If we breath in cold air, we have to raise the core body temperature by some other method, i.e. moving about. We also have a relatively small surface area (couple m2), which we then cover in clothing, to stop heat transfer. Don't believe the claims about Far Infrared, they don't really 'penetrate' the skin much, thankfully. Microwaves, which are the next longest named range of the electromagnetic spectrum, don't really cook from the 'inside', ask any chef. @NMarshall If I every see, or hear about some novel technology that is based on simple principles, I always ask myself 'why is it not used by everyone'.

Did he get a new name after that.
