Why would you not improve the current insulation to at least current regulations.

Will that be the same idiots that claim they don't work and never, ever, pay back their energy debt.

I am in a Bird Flu area, avoiding them all.

What temperature do you intend to store DHW at, that changes the number of kWh stored and the recharge time. Keeping the temperature as low as possible reduces the losses and increases the CoP. When guests stay, put the immersion heater on, cost less than a bottle of cheap wine.

I have had none this year.

Do you man the power taken to run a kettle ~2.8 kW, or the energy to boil a kettle full of water ~0.16 kWh. I had a quick look at the first 72 day of this year, daily mean of 16.3 kWh, then looked at the 72 days from June 1st, 3.1 kWh. So 3.1 kWh/day for DHW and everything else (ish). So to heat my 48 m2 house takes, on average 13.2 kWh/day. 72 days is 2448 hours [950.4 kWh] works out at a mean power of 423 W, or 9W/m2. The mean room temperature was 19.2°C, mean external temperature 7.5°C, a delta of 11.7°C. The mean room temperature is a little lower than I aim for [20°C], but the hourly profile is pretty good now [delaying the start of heating helps]. With my new draught proofing measure this year, I expect to see a reduction in usage and an increase in temperature to close to the target. Below is a more detailed profile.

@CADjockey Thanks. I assumed it was something fairly basic. Do you mean recycling or recirculating to/from the header tank?

Do you get your car 'borrowed' a lot.

Have you been reading this weeks New Scientist!

In the middle of Lidl last week they had a self darkening wielding mask and an inverter arc welder. Wait a while and they will have a band saw again. Failing that, they have a cordless angle grinder, batteries (and I assume a charger somewhere) and a contraption to mount the angle grinder to make it into a cut off saw. Sure they will have a tin of Hammerite as well.

Welcome. Add heat loss calculations, airtightness and condensation risk analysis to the list.

Would not thank me for not flushing it.

I chopped my beans down last Monday. I think I may have planted too many in the container. Then not watered them enough. Always next year. Got a crap crop of potatoes as well.

Why do you think anything a politician says should turn into reality.

@CADjockey What are you doing to clean the water before use?

Welcome. Ah, flat roofs. There are many methods to use, but if you just get it GRPed, problems solved, forever.

Yes, but some can disappear. I was with Lavabit, as was Edward Snowden, that got closed down, then I was with Gawab, they got bombed out in the Arab Spring. I got a Proton account, nice and secure, but cannot remember the passwords, and there is now way to have it reset. I thought I heard that you can keep your email address from old, mainstream, providers, but as the last time I used that type of service I was with AOL in the 1990s.

When you think of all the different types of cables used, how they are installed, when they are installed, then add in all the 'devices' connected to them, and the difference in business plans that run all the worlds servers and internet services, it is amazing any of it works at all.

I think grid tied inverters test the impedance of the grid as well as voltage and frequency. So not as simple as putting a 50 Hz, 230V signal into them.

What are you (and everyone else) going to do when this 'too good to be true deal ends?

Chesil Cliff House has apparently been bought, but not by Harry Styles.

You already help towards my £50/year water rebates. Still the most expensive in the country, and probably the world.

If I lived on a small island I would keep very quiet about what I have spent.

That is because the mother (expletive deleted)ers never come in at 6AM to see the preparation for there meal.

Just getting my morning coffee, £2.85. Sitting on a comfy dead cow sofa, served by a very nice boy. And now I have the staff login for the interweb, a better connection than my 4G when I am on the promenade.
