Things are done different down here. Some think they actually own the sea.

What we called the ones at the old Excelsior Hotel at Heathrow. Wish I had known the 'real' name, would have changed it to Pillocks (which I think is an olde word for cock).

If architects are there to give 'vision', surely they should charge a similar amount as fortune tellers at the end of a pier. About a tenner.

That it was a business. In the end I think the brewery paid out, but he is no longer the landlord if the pub.

A Northern Irish mate of mine, who just happens to live in Scotland said something similar. But for other reasons. He actually said he would live in a treehouse and smoke cannabis until things changed. I shall mention fitting a sprinkler.

Get the book quick.

They rented the place, so landlords choice. And a rather large war came after. Because they are dishonest and morally bankrupt.

DHW storage is an odd thing. The cylinder rarely goes below 30o C. If you then heat to 48o C, that is only an 18o C lift. Assuming a mean temperature in the cylinder of less than 48o C, say 42o C, then that is an even smaller lift. 200 litres of water will require 2.8 kWh. Which is about a baths worth. I found that my 200 lt cylinder, heater to 50o C, was adequate for 2 people. When I had guest, I just turned the top element on, adding in an extra 1.5 kWh per person seemed fine. So my guests cost me 60 pence a day.

When I first came around I never noticed your modules. May have been different if the roof had red tiles on it, but then, that is a Norfolk thing.

The Queen has a turbine at Windsor. https://www.bbc.co.uk/news/uk-england-berkshire-16276225 Not sure how far it is up to that hippy housing development, but lets us say it is 600 miles round trip. If your car does 50 MPG, then that is 12 gallons of fuel, 55 lt. A litre of gasoline has around 9.5 kWh of energy, so that will be around 520 kWh. To offset that with electrical energy from a turbine, it would have to produce 60W of power for a year. After that, your are quids in.

Some people modify central heating water pumps. Never seen one being used, just read about them. But if you have an old washing machine:

Noisy too. Fitted a 3 kW SMA to a 3.5 kW array. When it was at full chat, the cooling fan was very load and 500W was coming out as thermal energy. It was fitted (against my advice) in a spare bedroom. If possible, stick the inverter on the coldest side of the house.

Good old wikipedia has loads on turbines. https://en.wikipedia.org/wiki/Water_turbine Don't think this applies as, they just refer to it as turbine efficiency. Think it is do do with the uncompressability of water. Though agree that with small water turbines, the efficiency is rubbish.

Power = Head x Flow x Gravity

You need to look at pico hydro systems. If you want to help run your ASHP, then you will need an approved inverter, and notify your DNO about the new installation. Be easier to run it direct into a resistance heater though. The bigger you can get the drop from the pond to the generator the better. Let gravity do the work. May be worth you getting this book. https://www.amazon.co.uk/Renewable-Energy-Power-Sustainable-Future/dp/0199261784

When my Father was a teenager, his family home burnt down. They got rehoused, but the original house was not rebuilt for decades. A more resent fire down here in a pub kitchen, which damaged the living area of the building was not paid out for by the insurance company. The reason given was that the tenant landlord had not declared that he had been bankrupt a few years earlier. So live is never simple.

Not really. It is more efficiency to run DC over longer distance for any given cable size. So just a matter of doing the sums. There was a guy, from the other place, that lives near to me. He had a ground mounted array that ran DC a good 50 metres on the standard 4mm2 cable. It worked fine.

Could be because the risk is human life/injuries and not the actual building.

Yes, the 1300 was, not sure what I was thinking off. Still, most run on CP tyres. Can you still buy crossplys?

That is because the MM weighed little, was RWD, and ran on crossplys. If you remember, Formula 1 only started using radials in the late 1980s or early 1990s, can't quite remember when. It is one reason that they could easily run a race distance on a set.

Yes it would. All it does is take some basic material properties, some basic air change numbers (no idea what MVHR would do to it), then from internal and external temperature distributions differences (which are pretty normal around the mean), pro ratas the amount of energy needed to keep it at a steady temperature (the actual mean internal temperature). One problem is that where I live, there is relatively little deviation from the mean, not like places like Canada (saw pictures today of where I was a couple of years back, seems to have improved Halifax). I like this approach as good weather data is easy to get hold off, good building data is not.

I am still impressed that my simple model that I knocked up this morning is very close. Makes me wonder if a statistical approach is best. But then I would say that as I like statistics. I may have to test it against a smaller dataset of temperatures, the one I used was pretty large, 42,000 datapoints. I may have to put some test equipment into my Mother's house next time I am up. Her kitchen is almost the size of my house, and it is made of bricks. Could be interesting.

In parallel, be rather high voltage otherwise. Not sure I understand the question. Test for what?

Timber frame is better. Goes back to something I said a few years ago. I had a hunch that brick/block/concrete house would be naturally cooler and need more heating. They also do not benefit from being significantly cooler in hot weather. To get that benefit, they need to be very large and have even more mass (think wine cellars). Then you pay for that in the winter by needing more heating.
