Well the sun out is because the windows are small, the winter heat leaking out is because they are usually single glazed. I don't know what it is about the British and the fixation with large windows.

Basically what @JohnMo did, but with an A2WHP.

Taking those modelled phase shifts if 7.2, 10.3 and 12.5 hours only really apply on the 2 days a year when each hours of daylight, or hours of darkness, coincide with the phase shift. The other times the building is cooling or heating. Did you just model a wall? The two biggest influences are the glazing area/orientation and the uncontrolled ventilation rates. A thermally inefficient floor can have an impact as well. The footprint area to perimetry ratio makes a difference to. Basically once out of the tropics, daylight hours plays a larger and larger harder game the greater the latitude. The UK also has a strange climate, not easy to model reliably as we can have warm nights in the autumn and winter (last week was over 13°C), but quite cold in the spring. Much of this is to do with the sea surface temperature around the UK. It is this relatively high winter SST that makes the UK cloudy.

Quite a few about now. Some can be had with a DHW system included. For a new build, combining ventilation, heating/cooling and DHW should be seriously considered. Having said that, I tend to think that it is easier to separate them as they do different things, at different times and at different temperatures (the 3Ds).

Was chatting to a van driver the other day, he had fitted some 'nice' wheels (actually is a red light to me if I see non standard wheels, especially on a van), the dash lit up that he had 'low tyre pressure. Apparently this is common and has to have the ECU/Sensors recalibrated. Good I say as that red light to means a twat is driving.

The physics behind heating system is, at worse, so low that a 12 year old probably learns it at school.

There are a number of factors that govern PV yeild. I am black and proud (well on that map).

Most car journeys are really quite short, hardly seem worth manufacturing extra battery packs, building an infrastructure for the extraordinary journey. Battery technology in its current form is only about 30 years old, shall we remind ourselves what cars in the 1920's were like. Now let us look at what an EV from the 1990s was like.

What you need next door is a company that needs low temperature process, so a commercial laundry, or drying facilities like grain drying.

I would worry about what sort of 'data' is being moved around.

We are not going to wake up tomorrow with nothing but EVs in all our drives. 2021 there were about 190k, 2022 270k, 2023 315k, 2024 382k and 2025 (TD) 386k. So still going to take a while.

I filled up today, well put 30 litres in. The car in front of me was already filling up, was ten minutes before they came back to the car (with coffees), then 4 minutes before they pulled away. I filled up in 3 minutes (pay at pump). So a total of 17 minutes. Now a 150 kW charger could probably pump in 40 kWh in that time, so about 160 miles. I looked at this a few years back, worked out that we could charge 3.5 million cars without any changes (apart from charging points), and 7.5 million cars with minor changes, but all without adding capacity or infrastructure. I posted it up here somewhere.

Never had any incentives attached to it, but planned conditions, until recently, meant you needed permission.
