Mine are constantly down. But i am a pygmy.

Shorter during the northern hemisphere winter

Has she got cataracts? Was the first thing I noticed. After they put in new, shiny bright, acrylic lenses, you only need 0.25W/m² to read by. That is about 32 lux. Have I ever mentioned how painful a white background on a screen can be. So simple to just put the gentlest if grey tint on it. Do it once on a website, it is done forever, for everyone.

Self builds are new builds.

Calculate the power output and divide by the floor area to get the W/m².

I am concerned that they are a relatively new, and small, company. Heat pumps are mature technology, so nothing game changing is going to happen. The problems will come with the control systems and inexperienced installers.

I think you will find that PU foams break down relatively quickly when wet.

I worked, for a very short time, for Iskra. They were the original designers. Should not need much to lower it, steel cable and a car. They were pretty robust. But not seen any old ones about these days.

It could become a Far Infra-Red heater, and we all know that they have been proved, though anecdotal evidence from suckers that have them, that you cannot get more energy efficiency.

No it isn't. I have known two people that would act like spoilt, attention seeking, children to get their way. They were both genuinely mental. Shows a lack of understanding of economics. Expanding the supply of something that is either genuinely scarce, or perceived as scares, expands the whole market. Limiting supply, or giving the impression that the supply is limited, shrinks the market. The British public have talked themselves into a lack of supply and high prices, neither is actually true. £315bn is pretty small in reality, the UK spend, in 2021, nearly £10bn on (expletive deleted)ing pets. https://www.statista.com/statistics/308266/consumer-spending-on-pets-and-related-products-in-the-united-kingdom-uk/

So 1 EV for the first lucky owner. You have to charge, or at least limit usage or it just encourages excess usage.

Technically possibly. Legally it is a mine field. Two things spring to mind. VAT and non payers. Nearly every community energy company I have heard about fails, and not many people have working shared CHP units, or shared biomass boilers. Just stick as much PV on everything. https://www.gov.uk/guidance/community-energy

What is the other place known as, Moron.

Wrong end mate.

Welcome. Which bit of Cornwall, it is a long county. Good luck getting a wind turbine past planning.

I think someone posted up that they had bought RED. http://www.red-limited.com/ https://www.hvnplus.co.uk/news/octopus-energy-acquires-heat-pump-manufacturer-red-12-04-2022/ Seems so.

The 600W one shows that it has 2 12V/7AH batteries. That is a total capacity of 288Wh. I tend to work on half of the stated capacity, it is safer.

Didn't Sunamp enter into a sales agreement with Fischer a few years ago. I may be wrong, and quoting the wrong company they did a deal with. https://www.asa.org.uk/rulings/fischer-future-heat-uk-ltd-G19-1023772.html

Yes. Insulation is not very glamourous, but it works. And never trust a builder to get it right.

Yes. Probably not that bad a price, £1/Wh.

If it was just for the MVHR, I would be tempted to buy a cheap inverter that runs of a leisure battery, which is on a trickle charger. But that is probably £200 quid in reality.

There is a purely unpowered, mechanical, solution, but looks dreadful. And rattle.

256 [Wh] / 23 [W] The watts cancel out leaving the hours. 256 / 23 = 11 [h] Yes How much is it?

If the closed cell is on the cold side, and the open cell on the warm side, at least the water vapour once condensed, will be sponged up. With PU the two biggest problems are shrinkage and moisture. Both cause I consistency problems.
