Is there a plumbing equivalent of the 18th edition electrical regulations, or is it that Part G.

Oxides of nitrogen. To get higher efficiency you need higher temperatures. This means higher pressures. High temperature and pressure, plus nitrogen, oxygen and combustions is how you make NO and NO2. The mining thing is probably an overstated issue. Partly to do with the definition of child labour i.e. under 16. I also believe that employing very young children us not an effective way to make things. Though I am sure there are isolated incidences of child labour, and slavery, still happening.

Interesting question. I would assume yes, as it can be pressurised. Isn't it more a case if an invented does NOT need G3. Is it possible to download the regulations from somewhere?

This half hour editing limit is a (expletive deleted)ing nonsense. Wanted to add this. Not as if the electric motor, batteries, or even fuel cells are 21st century technology. When the electronics comes from the 1960s.

Lots of trouble, usually serious. Why, probably worse for the environment than a modern gasoline engine. Carbon Dioxide is not the only greenhouse gas.

Before Bristol bans all cars.

what I want to know, though hybrids are down in value last time I looked. They are the better option for me.

My Ford, cost me 3k, now, 120k miles later, it is worth less than a set of tyres (except I buy very cheap tyres). Apart from usual maintenance things i.e. brakes (and they lasted 130k), only had a rubber pipe replaces, cost 100 quid. This is the first Ford I have owned (though driven dozens), and it must be the second cheapest car I have owned, the last MGB was the best, but it went up in value over the years I ran around in it.

Is that what your lease payments cover, and you have all the restrictions i.e. limited milage, only two scratches, no tears in seat fabric, no shoeprints on head lining.

I thought so to. Like renting a room from a cheap landlord in Bristol. Going to end in tears and pictures up on the interweb. What is the difference between the Zoe and the Leaf, same company makes them. This is her Mother

Do you still rent the batteries in those, or have they decided to sell them to you?

I have not paid in that much, nor have I seen a car that costs that much.

By how much?

Still not doubling in a decade. The ONS data is inflation adjusted.

Are the people that are making that car boomers? (suspect that some of it is inheritance money from the sale of his family farm, which is close to me) Seems that this is more a case of intergenerational wealth distribution. Still a ridiculous amount of money for a car. My 500 quid car can go further between fill ups.

Frequency distributions are probably the way to go i.e. mean flow temperatures by different temperature differences. There should be two peaks then, one for the space heating and the other for the DHW (assuming the flow temps are different).

I have not heard of this braking issue. Sound scary. And wipers should be very quick to adjust. With an iPace being designed by a British team, they understand rain and more importantly, drizzle onto dirty roads.

It is not often that a PV system will generate enough power to start an induction load like a heat pump compressor. You could fit a battery, and an over size inverter, then hope there is enough energy stored in the batter to start the ASHP while the PV is generating enough to run the ASHP and charge the battery. If an ASHP takes 5 amps to run (1.15 kW), and you have 5, 250W PV modules, the numbers seem, on the face of it, to match once inverter efficiency is taken into account. The problem is that the modules only deliver that 250W when the sun is allowing 1000W.m-2 of insolation to hit those modules, which is a rare day in the UK, and then they have to be facing the sun directly. Solar slates are very nice, hardly noticeable on a roof, but they cost a lot more and have lower output per unit area. And a lot more work to install.

Or incorrect for the doubling bit in the last decade according to DUKES. UK domestic electricity has gone up 35.5% since 2010. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/904105/Electricity_since_1920.xls

The bacteria is quite commonly found lurking in hot water taps. There is generally not enough atomisation if the right sized droplets to cause a problem. But there is a whole industry based on scaring the shit out of people about it. On another site, someone claimed that pneumonia was caused by contaminated showers, and she truly believed it, no evidence to the contrary would convince her otherwise.

I think what holds that back is the business model on commercial buildings. The building owner may not be the building management company, or the freeholder. Lease holding companies can put stringent rules in place as well. Not sure I want an electrician ripping my roof off, drilling into rafters, fitting flashing, or doing the structural calculations. The answer is to allow self management of the installation by making the rules and regulations accessible and clear. DNOs could help by having an open register of how much capacity can be fitted in any area, and what any upgrade costs would be.

Yes, I don't really have a problem with the EPC data. There is probably a reason that someone that claimed to be a Chartered Surveyor and fully qualified SAP assessor, was working in a local estate agent in one of the poorest parts of the country. She did go very quiet when she found out my background.

So about 1 MWh/year. Trouble is that it will be going into the main grid, via the very much larger local grid losses. Much better for developers to buy some land and stick a large solar farm on it with a dedicated connection. A lot of houses are just not suitable for PV, the roofs are at the wrong azimuth, shaded, too remote a location etc. Having said that, I still think about fitting some to my house. If I cheat a little (use the full width of my roof) I should get 8 off standard 1.6m by 1m modules on the SW facing side. Enough to heat DHW for 8 months of the year. So 2.4 kWp.

Not once steady state is reached. It could, possible, be a financial advantage.

And it showed my house having twice the area of all my neighbours, who have the same size houses. Think I shall get that estate agent to sell my place as she made it bigger than it is.
