If it was a wall it would be obvious. Trouble is it is s slow change, that gets confused with weather. Climate and weather are different things, why we have different words for them.

If it stays flexible (I think Icynene is flexible) then it should. PUs over expand during curing and continue to shrink for months, this can cause problems if the bond between timber and foam fails. Water is often used as the foaming agent.

Get them planted soon and hope they grow fast. What leylandii are good for.

First thing to do is run the setup through PV-GIS. https://re.jrc.ec.europa.eu/pvg_tools/en/#MR Then compare that to current usage (you can read a meter every hour to get a feel for what is going on. Battery storage, at the moment, is a nice toy to play with, but probably not worth it. But storing electrical energy as thermal energy probably is worth it. Especially if you can reduce the capital cost of an ASHP. There will be times when you over produce, and times when you under produce, but that is just a calculation to find out the overall ideal system and storage size. Look up the prices of DIYing a system. Probably much cheaper.

Part of the reason for having a warm floor in a bathroom is to speed up drying. It takes 2257 J/g to vaporise water.

Yes https://www.engineeringtoolbox.com/minor-loss-air-ducts-fittings-d_208.html

Could you not use a secondary thermostat that sits in a jamjar the sun? Pretty easy to make a solar sensor with a photoresistor, a RPi and a capacitor.

Are you making, yourself, most of this house?

Are you going to put some glazing into the opening's bracing. You seem to have a better fit that a window company. One drekley after the other?

How much insulation is under the floor, could be energy just leaking out to the ground. But fill us in with more details. Size of heated floor area, on how many floors, are they zoned separately, what type of heating system is it.

It is the amount of energy in the water that needs replacing, not time playing in it. You can get an electrical diverter that pushed the current to the immersion heater. Probably the most effective thing you can do to save money (apart from buying a washing line an dumping the tumble dryer). A SunAmp is always a possibility, but not sure how well the integrate with a ASHP these days). If it is easier, can't you use the utility/bike rooms. I used to live in Hertfordshire, mate sent me a video of snow falling this afternoon.

If it can be made to work, why not. Will there be room for a buffet tank and expansion vessel? Regarding your hit water, how often do you think you will need all of it in a short space of time? And would boosting with s 3 or 6 kW immersion get you out of a hole if you have guests. Are you having PV diverted to the DHW?

Some sort of platform maybe.

You need enough room to fit reasonably long flexible pipes to minimise sound transmission. Can you raise the cylinder up and have enough room under it for manifolds and maintenance?

Why would you do, or want, that to happen. CoP of 1, compared to over 1.

Worth remembering that the RHI payment id based on estimated usage. So if your house is thermally efficient, then you will not get much in the way of payments.

Which is, assuming a minimum tank temperature of 10°C which is ~4 kWh. If the max temp is set to 45°C then the volume needs to go up to ~100 litres, to store the same amount of energy.

Welcome So not finished after 40 years. That should cheer up others.

1 But one of those Portuguese Thermodynamic solar panels that work in the dark may get very high CoP. The Solar Constant is 1340 W/m².

Nothing wrong with that, you still need 200mm plus on insulation. I think that is what @joe90 has. One advantage of a decent slab is that you can reduce the cold bridge at the sole plate.

Where else would it go?

Fit mirrors, that will work a treat. Intact you could easily cast tinfoil into clear resin. That would make it waterproof as well. No reason you cannot fit PV to s flat roof. Do it yourself.

I have a theory that people that click on fake news links are easier to sell tat to. Magnetic resonance water purification that utilises quantum vibrations is my starting point. Or this. A house on the moon would apparently cost £44,525,536.42 Feedback is our weekly column of bizarre stories, implausible advertising claims, confusing instructions and more HUMANS 31 March 2021 New Scientist Default Image Josie Ford Lunar living “Fancy buying a house on the Moon?”, an email that plops into Feedback’s inbox asks, continuing, before we have a chance to say, “Not particularly”, “It would cost you £234k a MONTH!” “With Earth becoming increasingly populated and space technology advancing, it won’t be long before lunar living becomes the new normal,” this email, which appears to have come from a price comparison website, asserts. Yes, they were saying that back in ’69, too. Mind you, recent revelations about lunar infrastructure developments such as kilometres-high concrete towers and fully operational sperm banks (20 March) might be enough to convince us this is an idea whose time has come. Advertisement Alas, “Living on the moon is not as simple as life on Earth” – a statement Feedback would definitely describe as the under-variety. Building and transport costs, land licences and a property markup of 27.61 per cent, plus such boondoggles as solar panels, industrial-strength heaters and meteor-proof windows, mean we are looking at a surprisingly precise £44,525,536.42 for a first-time buy. Plus £1 billion for the nuclear-powered option. What planet are they on, we can only ask. Although, considering the pre-pandemic prices of some of the real estate we see from our London penthouse stationery cupboard, the answer might well be Earth.

Fit PV, that will take out 20% of the energy. If you have a decent amount of room, active ventilation between tiles and room may help, pipe the warmed air to a heat pump to warm your DHW. You could make up a small roof section and do some tests in your garden. I did this over at the other place. http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=5643&page=1 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7304&page=1 10 years ago.
