Still going to increase CO2 levels unnecessarily, pollute the local environment and need extra work.

You would have thought they would have had a point equalling a penny, rather than 0.125p.

She has a mouth like a sewer, and a Yorkshire accent.

If you take away too much choice in an office, you get disgruntled staff. I worked in an office with individual heating/AC settings, and lighting settings, it was rubbish.

She can swap it for this

I had a quick look and some claim to island. https://www.givenergy.co.uk/products#giv-hy-5-0-gen-2 Keep checking and make sure the installer knows what they are doing. Too easy to set it up on defaults and walk away.

Or remove the blindfold.

But is the inverter capable of running independently if the grid? What model are you getting?

Why not put another router down there that detects her phone when she sneaks in late at night. I think Wireshark can detect them.

When liquid water changes to steam it expands, by around 1700 times. It is the steam you need to worry about, not the thermal expansion of liquid water.

And before it is needed. Last thing you want to do it start poking about in the dark with a screwdriver.

Same problem with my Mother. Set the wireless thermostat to 23°C, which seems fine. Then find that the thermostat has been left in the kitchen. I have suggested that if she feels cold, get up and walk about for a couple of minutes, which luckily she can do now. Got home tonight, house back up to 20°C, it is lovely again. Condensation on the rear door seems to be drying out. Never seen it there before, but then it was leaking air around the frame until I sorted it out earlier in the year. Room is draught free and much quieter now.

Is it an 'islanding' system with automatic grid connection?

My house is small. I go out a lot.

Except in a small house like mine. The humidity rises too high and if the extractor fan is on, the house gets cold quite quick. Having MVHR would sort that to a certain extent.

Yes, I think so. Would need to do some data collection to find out. Often thought that a couple of DHT22s either side of the fan/heat exchanger on an ASHP should be able to collect enough data. Was going to do it on a work mates ASHP but he moved house.

What always concerns me with anything to do with bath, shower and basin waste is blockages. Mainly girls long hair. Add a heat exchanger into the mix and it is just adding complication. Maybe a waste water to air recovery unit would be more practical during the heating season.

Shorter distance than I travel to my Mother's.

Right. Are these the same units https://www.amazon.co.uk/dp/B09QQCVGSX/ref=sspa_dk_detail_2

Hill, clay, subsidence and now buried bombs. I will take the property off their hands for 10k. You have actually raised a very important point. Without being 'in the trade' it is very hard to to find out what companies liabilities are, and how they can be enforced. Probably why we need solicitors to act on our behalf, then if the builder (expletive deleted)s up, we can claim against the solicitors insurance.

Welcome. Why bother with a battery when for a large slice of the year a cylinder of water will use all/most of the PV generation.

When I have a free day, a pencil, paper and a dictionary, I shall go through that. Even turning legalese into something approaching English is hard work compared to thermodynamics.

Shall order a couple when I get home. Sure I can safely modify them to be wired directly into the storage heaters and immersion heaters as they are a gnats under 3 kW each.

Not sure how plentiful it really is. Takes a lot of land and water. Microwaved bamboo could be used to build super-strong skyscrapers TECHNOLOGY 24 April 2020 By Alice Klein New Scientist Default Image Bamboo can be made strong enough to build planes or cars by microwaving it Aaron French/EyeEm/Alamy Scientists have created an exceptionally strong, lightweight material out of microwaved bamboo that could be used to construct the next generation of skyscrapers, cars and aeroplanes. At the moment, steel, concrete and bricks are the most commonly used construction materials, but they are non-renewable and their production contributes substantially to global greenhouse gas emissions. Bamboo, in contrast, is a fast-growing, renewable material that is already used in houses and scaffolding in many Asian countries. However, it is not strong enough in its natural form to construct tall buildings. Advertisement To make bamboo stronger, Liangbing Hu at the University of Maryland in the US and his colleagues treated it with chemicals to partially remove a substance called lignin, then microwaved it to remove water. This caused the bamboo to shrink by about a third of its size and its cellulose fibres to pack together in dense layers. The tightly-packed cellulose layers were able to form strong chemical bonds called hydrogen bonds that enhanced the strength of the bamboo while still maintaining its lightness, says Hu.

It could also withstand slightly more compression than concrete and bricks and did not degrade when left outdoors. These properties make the material suitable for constructing skyscrapers that would be lightweight but stay stable by being strongly bolted to the ground, says Hu. It could also potentially be used to make lighter electric cars that could make up the weight with bigger batteries for travelling further, or lighter aeroplanes that require less fuel to propel them, he says. Hu’s team and other research groups have also used wood to make super-strong, renewable building materials, but bamboo has the advantage of growing faster, meaning it can be produced on a larger scale, he says. Hu and his colleagues are now planning several engineering projects to test the potential of their microwaved bamboo in real-life building contexts. Journal reference: ACS Nano, DOI: 10.1021/acsnano.9b08747 Menu Bamboo road bridge can support 16-tonne trucks TECHNOLOGY 19 December 2007 By Mason Inman The novel bridge with horizontal beams made from a bamboo composite proved strong enough to support even heavy trucks (Image: University of Southern California) Bridges built from bamboo instead of steel could provide a cheaper, more environmentally sustainable engineering solution in China, a recent experiment suggests. A novel type of bridge with horizontal beams made from a bamboo composite proved strong enough to support even heavy trucks in tests. The bamboo beams are cheaper and more environmentally friendly to make than steel or concrete, yet offer comparable structural strength. Yan Xiao, who works at the University of Southern California, in Los Angeles, US, and at Hunan University in China, led the development of the bamboo beams used to make the bridge. Advertisement Instead of using round, pole-like pieces of unprocessed bamboo, which have been used as building material for many thousands of years, he came up with a way of assembling timber-like beams from many smaller strips of bamboo. Precise details on the process remain proprietary, but Xiao says the strips are cut from large stalks of bamboo, arranged in multiple layers, and bonded together with glue. The technique has never been used to build such large beams before, Xiao says. Sustainable harvest Last week workers finished assembling a 10-metre long bridge of Xiao’s design in the village of Leiyang in Hunan province, southern China. Using prefabricated beams, it took a team of eight workers just a week to assemble and did not require heavy construction equipment. It proved strong enough to carry a 16-tonne truck and, and based on structural testing of the bridge, should be able to support even more weight, Xiao says. Pound-for-pound, bamboo is stronger than steel when stretched and more robust than concrete when compressed. Also, stalks several meters tall mature in just a few years, rather than a few decades as with trees, so more can be harvested from the same amount of land. Furthermore, since it is a grass it can be harvested like mowing a lawn – leaving the root system intact so that the plant can regrow. Green solution Bamboo beams could work for bridges up to 30-metres long, Xiao says, making them suitable for carrying pedestrians in cities or cars on highway overpasses. “I think very highly of the work that professor Xiao is doing,” says architect Darrel DeBoer, who works with unusual building materials. “It’s quite worthwhile to find alternatives to the concrete that we are using way too much of.” DeBoer notes that cement production releases a lot of the greenhouse gas carbon dioxide: 5-10% of global CO2, according to different estimates. This is an unavoidable part of the chemical process used to make cement from calcium carbonate. Bamboo, on the other hand, soaks up CO2, as it grows. “From an environmental perspective, bamboo is a great choice,” DeBoer says.
