And here are the means for @joe90's Your loft is amazingly stable.

Because if you fit UFH you don't want to warm the ground up. You have to remember that the ground under a house really gets above 12 to 14°C.

You have your own nuclear fission reactor, cool. Just pump it into the house to warm it up.

I shall see if I have the old spreadsheet I did a couple of summers back. This lockdown is good, means I don't have to 'cross the border, under the cover of darkness' to get into Devon to see you. But come the spring, we should be alright. Here we go. Blue columns are the complete year, red line is the winter, Dec, Jan and Feb. You could possibly benefit financially, but when you look at your absolute numbers, they are pretty low.

Yes. Can you add 300mm of insulation, and then 100mm of concrete? You may need more 'depth' around the edges.

Most of the SunBoys have Bluetooth connections to. See if the Growatt does, ar you may be able to get an attachment. That energy meter I sent the link for could log the production. I think the sender unit in that one can take up to 3 inputs, so one could be on the generation meter and the other on the import meter, if they are close to each other. You would need a RPi to do the logging though or it will just sum the inputs.

Just sent a message to my mate in Whitchurch, no reply yet.

Electricity takes the path of least resistance, so flows to where it is needed. Think of it as a pond what has many streams coming off it, each steam has a different flow rate (the resistance) but if there is a jug at each end (the load), once the jugs are full (all at the same level), then there is nowhere for the power to go.

Sent the special bitcoin to you already, have you lost it.

I work with someone that thinks the more you spend, the better quality you get. I have just posted him the link, be interesting to see if he buys it.

That could save me 600 quid https://www.ebay.co.uk/itm/Electric-Paint-Sprayer-Gun-Spraygun-Handheld-Fence-Home-Garden-Outdoor-Indoor/122567690666 What are they thinking

Yes I could, but got no use for the walk on glazing that comes with it, unless I make a spray booth. Shall look on fleabay and the discount stores.

Well just went to get one, and they are out of stock, nationally, and you cannot order one. Oh Bum

I may go and get one then. Cheers.

@pocster How have you got on with your repair with that paint sprayer?

I agree. We already have a transfer of income from high earners to low earners though the income tax and benefits systems. What we need it a simpler system that is transparent, not another layer of complexity.

I wonder how many are converted houses? Not all flats are high rise. They are probably diminishing in number.

Don't forget to add in evaporation losses to your calculations. Re the flow rates for cooling, work on the ones you already have. Then see how much power is delivered. Corby Council used a large pond to collect and store energy for their community swimming pool. The system never worked right and they changed to gas heating and conventional airconditioning.

There is, surface area to floor area is one metric, terraced housing is another. Orientation and wind shielding are others. I think forum members are biased in what they build. Is anyone here building a semi?

Flats could have A2A heat pumps, or community heating. Terraced places may have enough room outside for a monoblock, but could have a split system. Both flats and terraced have relatively low energy usage by definition (less exterior wall area), so a smaller problem to solve.

The same argument that the automotive industry has been using for decades, but they seem to manage to produce cars to a higher standard for, in real terms, less money. The biggest problem the house construction industry has is the people they employ on site.

Probably all of the above. I made a cuppa in about 30 seconds with my kettle.

If you want to know how not to heat your swimming pool, come down here. https://jubileepool.co.uk/pool-info/geothermal/

Just tried it on mine, throws an error.

My kettle cost a tenner from Tesco. I am very dubious of any advantages.
