Welcome. Move to Cornwall. Moving to Devon from the SE is like being a little bit pregnant.

Plot some correlations they usually show what is happening. One problem with modelling a buffer system is that there is a time shift between energy input and a rise in room temperature, this can give odd looking results as yesterday's inputs, yesterday's temperature differences may not correlate to what you see today. Starts to become messy modeling.

Octopus Cosy - new tariff for ASHP owners
SteamyTea replied to George's topic in Air Source Heat Pumps (ASHP)
That is why they are offering cheap power I suspect. A lot of the people that take it up will already have PV. -
Half the ratio and the torque doubles for the same power.

My daily mean, so far this year, is 7.9 kWh/day, 2781 kWh for the year to date. I use around 3 kWh/day for DHW and about 1 kWh a day for the rest. So 4 kWh/day for space heating. House is 50 m2. So total energy works out at 55.6 kWh/m2.Year. Heating is 28.2 kWh/m2.Year. Those number will go up a little for the last few days of the year, but not much. Yesterday I used half the amount I did the same day last week. I have just got in from the Montol and it is 10°C in town. Ansom my bird.

Makes my EDF E7 rate look very attractive, and I don't have to buy anything new. -
IWI Wood fibre alternative build up using OSB or Woodwool

As this is an engineering problem, do you have a WVTR for all the materials you are considering? Good luck getting it from the lime plaster people. They seem very coy about the numbers. -
I have 5 doors and 5 seats in my car. While I have used them all over the years, I have never used them all at the same time, and probably never will. But if I take the rear seats out, I can carry a lot of stuff. Now I pay more than I need to most of the time, but it is cheaper, overall than riding around in a motorbike and hiring a car, or van, when I need one. It is all to do with marginal cost differences. Through in division of labour, and market failures, and we end up with the cheapest option for the services we require. What amazes me, especially about the RE doom mongers, is they, like conspiracy theorists, seem to think they have discovered something special, a problem the generation industry does not know about, or are hiding it from us sheeple. You can go to university to study renewable energy systems, can't get more mainstream than an engineering course. I don't here conspiracies about engineering and how non of it really works. Probably because we are used to it, it surrounds us every day, has small, incremental changes that don't worry people unduly, is at a price that most, in the developed world, can afford. Most people will not care how electricity is generated, just as long as it works when they flip a switch. That is probably the best thing, we don't want people, who don't know much, thinking they can game the system with ridiculous ideas. Why I don't suggest suicide showers. They work, are cheap to buy, eady to fit, and (expletive deleted)ing lethal.

Mine was done 3 years ago because the seal had gone. Noting wrong with the actual thermostat. That is on a car that was then 11 years old and about 140k miles.

If they are that important, you really should have a UPS fitted to them. Built into laptops, unless like mine, it stopped working off battery power a while back. Still, it is several years old so may treat myself to a new 'cheapest I can find' one.

Right. Here is the last two weeks data. I know that I live in the warmest part of the country, but for here, it was artic. Work out at 4.6 kWh/m2 for that periods space heating. As my heating season is about 12 weeks, that will be 28 kWh.m2. Not too bad, especially as the mean temp was only a gnats over 1°C down.

VAT of the energy price?

PV 12v. DC panel supply, earthing question
SteamyTea replied to Marvin's topic in Photovoltaics (PV)
No. Unless the manufactures instructions say so. And that would almost certainly be the inverters MI. -
Where is the kWh price heading in 2022?

What is there to moan about, with my usage pattern, I should be saving 20p.
