It is entropy. Thermal energy, in the context of liquid water heating, is quite disordered, so higher entropy. Electrical energy is much more ordered, so lower entropy. Lower entropy to higher entropy sit in the better (more efficient) corner of the Carnot Cycle. Efficiency calculations become a bit tricky when looking at renewable energy. If you calculate the area of land needed to supply just enough energy to heat a known quantity of water, a fixed number of kelvin, then ST looks impressive. But if you look at time a ST system sits doing nothing, maybe 22 hours a day in the summer, and compare that that what a PV system can do i.e. heat the water in say 3 hours, then help run the rest of the house for another 10 hours, you get a much better utility return. PV is now cheaper, simpler and more reliable. Roof integrated PV is a similar price to roof slating.

Success Planted 26 April, so 14 days. Time for the slug pellets.

Sum of Price of components times number of them. Easy.

Thankfully I don't have PV, it would just be powering my neighbours 500 W external flood light. Odd as she is in all day and night and never seems to notice it.

Welcome. Looks similar to my old place in Aylesbury. Is that mould growing around the downpipe above the porch? If it is, get that sorted tomorrow. If reroofing, and the orientation is suitable, roof integrated PV is worth looking at. Not as if you see the roof from the ground. Chimney may be a problem, but they usually are. Consider what you want to do with it. Insulation will almost certainly be internal, so that is the time to sort out the airtightness around joists. Or the problematic area as it is known. Heat loss, condensation and external water ingress do not sit well together in older buildings. Ask 10 people on here and you will get at least 20 answers. Good luck with living with the dust.

Michael Jackson is helping to push up daiseys. But Freddy Mercury killed pansies.

I would not bother with solar thermal, it needs maintenance and is a one trick pony. Once the water is up to temp, it then just sits there waiting to go wrong. PV is much more reliable. It is easier to install as well. Wire are easier to route than pipes.

Try shitting on them. Don't think mine have sprouted yet. Shall check in morning.

No, it is the huge extractor fans we have to use, even worse if you cook on gas. Not unusual to be 40°C by the hobs/ovens/fryers, and struggling to get to 16°C in the actual eating area. There is often a double door between kitchen and restaurant for this reason. Trouble is is gets propped open to help cool the kitchen. Opening exterior windows and doors always seems like a good idea, but the orders then get blown off the rail. Oh the life of a chef, it is a mugs game.

Could be a catering establishment. Have you ever wondered why it is so cold waiting for a takeaway. https://www.lakeair.com/air-changes-per-hour/ Commercial kitchens are 15 to 30 ACH.

1000 litre in a cubic metre. 3,600 seconds in 1 hour. So Total Litres = m³ x ACH x 1000 Litres per second = Total Litre / 3600 So take a room that is 10m by 5m by 2.5m 125m³ ACH is 6 125m³ x 6 ACH 750m³ Multiply by 1000 750,000 litres To change that in 1 hour, and express in litres per second, divide by seconds in an hour. 750,000 / 3,600 208 Lt/s Can call that Radio Luxembourg. Or lt/s = (Volume [m3] x ACH) / 0.2778 So 125 m3 x 6 ACH 750 / 0.2778 = 208 Lt/s

Only when this one is finished with. (Childhood's End is my favourite book)

Went to a good school, it was approved.

Powerful magnet on the side should sort it.

Then he is responsible. Get him to sort it, one way or another.

Dig a channel into you neighbour's garden.

Well I think this is the whole thing. The pipeline was private, though connected to public sewers. No idea if the final sewage treatment is private, with only the pipework crossing your land. I would give the local water company a call and ask.

Went to kindergarten in the Netherlands, state school in UK, then a private French one, then a prep school in Kent, then a Public school in Oxon. Also, as my mother was a teacher, sat in a lot of classes in International schools when we were abroad. All my school's were very, very different. Not sure if changing school every 2 or 3 years is actually a good or a bad thing. As a kid, school was just something 'you had to do'. College and university was totally different. My choice of what I wanted to study, and where (away from family and friends, or distractions). Both school and the workplace have, generally bored me. Not the work, it is the small minded pettiness of it all. Being seen to be good was more important than actually being good.

Either.

When I bought this place I took out a one off insurance to cover the shared sewage pipe that crosses my land. A few years back I had notification that SW Water had taken over responsibility of all the sewage pipes. Never got any of my money back from the insurance company.

Why it is pre set with no user options.

One of my assignments when studying renewable energy was to design a system that supplied power for 3 days. I designed a cascading system. Basically anything could run for 4 hours, then stuff was disconnected, big loads first. So no DHW or heating, then oven, then freezers and entertainment, eventually just left with lights, I considered lighting to be a safety issue. Costed it out at around £60k using lead acid technology and islanding inverters. Class mate if mine found a biodiesel generator, I considered that cheating. He got better marks. He used to get better marks in the Mathematic assignments, and I did them for him.

You are near Bovington, could be fun scaring the neighbours with a midnight pyrotechnic show. My Kindle has Fire in the name as well. Who will be the first EV maker to use they word, Fiat.

You need to be on the ground floor.
