No so different from PV then. PV has the advantage that it can deliver some power at lower light levels as it does not rely on temperature difference as the main switching mechanism. And it don't need servicing, pipes, mechanical valves, antifreeze, expansion vessels, over pressure and temperature safety systems. Wires are easy to fit. And when the pool us hot (which you may be able to do with just resistance heating to save on installation costs), you can divert it to charge an EV. But get those thermal models fine and checked first, you may find that better pool insulation changed a price point somewhere else. And don't forget the evaporation losses.

That works out at 250/m2. https://edavies.me.uk/2012/01/pv-et-flat/

It is a good think. You can extract about 4 times as much energy out of water than dry ground. GSHP are really water source heat pumps with the water heated by solar energy.

Yes, unless they vanished in the last month. https://www.gshp.org.uk/RHI_Domestic.html

Right, you have 3 things to do. Heat a house Heat DHW Heat a swimming pool. These are quite different things, done at different times and to different temperatures. Treat them separately. As for ST and PV, PV will probably be cheaper, more reliable and better looking. Don't discount a GSHP, they are less weather dependant, but don't share the loops, this will be a problem. They may cost more and have the HP part inside, but it is not as if you are scratching around to save a grand, and you have plenty of room to hide the noisy part away. You also have to think about heat recovery and air conditioning. You could probably run all your DHW of the extraction from the pool room.

And a fair few neighbours as well. And no chopping down and post coppicing processing. Always worth comparing the energy yields, and associated power outputs for different energy sources.

Pretty ropey land then. Farmers would not build a solar farm on productive land, it is just not financially viable. We are heading into 2nd agricultural revolution (or a third one depending on if you count the improvements in crops as separate from mechanisation). We easily grow 50% more crops per unit land area than we did 50 years ago, this will probably double in the net 25 to 30 years with better practices and monitoring, as well as GM crops.

His original design was not very good, one of those combined DHW cylinders with the F&E on top, then sprayed with a bit more foam. I just think they are very expensive for what they are. Useful in a tiny house, or flat, but only if heated with electricity only. As soon as renewables or gas come into the equation, it is a very expensive option.

Cover it in PV, it has an energy yield about 40 times of biomass.

Welcome There are a of of opinions, and some useful facts. And some Walk on Glazing for sale.

Is it really good agricultural land, most of Cornwall is grade 3b and below. That is by value, not calorific content or staples. I wish they would open up more areas for commercial usage, worth taking a look at the economic activity of an area. Mine is not all pasties and surfboards, most is services, with tourism accounting for about 12%. Any new business would have to comply with modern environmental legislation. I feel there is a bit of NIMBYism going on here. Half the time people are complain they cannot get planning consent, then want to stop anything else. Look at an aerial map of the UK and tell me what the predominant colour is, we have urbanised less that 10% of the land area, with housing being around 2%. The UK produces more area of cars every year that all building works.

I think you get that option when you connect your computer to the network, bit like when logging into the O2 'free' wireless at cafes.

Dead easy with 20 quid of hardware. Be interesting to see if yours is still logging, hot to be a couple of years since I was last over.

You could always make an offer to buy the site.

More like calling one a pig, and the other a snake. Different species.

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.
