Because I respect what he says. If we all marked each others homework, not much else would get done.

Are the two compatible? I painted a door with a water based gloss, there are patches where it has reacted and stayed soft where the previous gloss/undercoat was not fully removed back to the timber. Even 'same base' undercoat and glosses and react.

Or putting the brake on. Not quite the same, more like pulling a plug lead while keeping the throttle position the same (PI (expletive deleted)s up the analogies a bit, but you get the idea).

I don't understand that. Is it because of your usage pattern? Here are my current rates for E7, in the SW, the most expensive place in England. Electricity day unit rate: 40.86p per kWh Electricity night unit rate: 15.05p per kWh Daily standing charge: 65.19p per day Day 83 kWh, night 264 kWh, for the last 66 days. 5.25 kWh/day. Once taxes and rentals are added, that works out at 33.4p/kWh

@markocosic mentioned about it on here somewhere.

Is your plumber French, or worse, Portuguese.

Does to me.

Worth checking how the HP modulates, some just open or close the expansion valve, that just reduces output without saving any input.

Wait. https://www.statista.com/statistics/374970/united-kingdom-uk-gas-price-forecast

It was really to point out that there is quite a lot of energy stored in soil. What sort of temperatures is the brine that gets pumped around GSHPs? I was thinking about your radiator idea. I may go looking for an old fridge, put a bucket inside it, plumb out of there to a pump and pass it though some radiators. By boxing in the fridge, with an airgap, a fan can blow air though it, kind of Water to Air HP.

Rent it out to emmets

One has to start somewhere. Not so much with a borehole. As earlier, have to start somewhere. Borehole systems work very well, quite a lot of places down here have them, may be b cause Kensa are local.

Ah right. GSHPs are geology dependant. Soils have about the same SHC as rock, around 0.8 kJ/kg.K. Density is a little lower, say 2000 kg/m³. If a 100 m borehole system can get a third of that energy out, down here, were the mean air temperature is 12⁰C (borehole temp is mean annual air temp) and assume the ground can be cooled to -15⁰C. 100 (m) X 2000 (kg/m³) X 0.8 (kJ/kg.K) X 27 (∆T) = 4,320 MJ. Divide by 3 1,440 MJ, or 400 kWh. That is obviously before any thermal replacement i.e. heat seep. Would easily do my house, and a more modern place would probably use half the energy. So I think it is a valid idea.

What has a flowing aquifer or hot rocks got to do with drilling costs. If someone asked me to drill 1000, 50 m boreholes on a new build site, I am sure I could do it cheaper than 500, 100 m boreholes scattered around the area. We are just not used to drilling boreholes in the UK, so has become a self fulfilling prophesy.

In what way Individual usage patterns, different expectations, all sorts of things. Just different energy tariffs could make a difference. Yesterday's You and Yours showed, yet again, how hopeless the public understanding is. Not that many will listen to it. As an example, two callers, both barn conversions. One pleased, other not. But no detail, so no way to make a decision. Totally pointless show in the end.

Yes they would, we would have perpetual motion machines otherwise.

Is it 100W/m or there abouts. Forget communal heating, the English are just too self centred to share anything. Recipe for disaster. So would have to be stand along for each property.

That needs a lot of unpicking.

And Would both increase thermally losses from the house. But maybe if radiators were just fitted on garden walks, that would do. I like the idea of shooting air out a chimney, all those millions of houses that have chimneys could have a heat pump in the hearth, rather than a wood burner.

Or GSHP. I would think on a new development, and this does depend on local geology, sinking boreholes is a pretty small cost. They could also get water as well. If I had put a borehole in my place in 2005, I would be quids in now

Nor are rural areas. An Eco Park near Porthtown has a festival every year. This year they were told it was too noisy for some birds. We all know how noisy birds are at 4 AM. Then there is is tractors, motorcycles, and general traffic noise. Oh, and the RAF, Air Ambulance, Coast Guard. The Heliport for the Scillys. Largest fishing port and the associated wet markets. Tulip Bacon are near Redruth, Constant, 24/7 CBT artics on the move. And the wind noise, that is pretty constant. Cities are havens, if you can afford the good bits.

Can't find the ONS numbers, but this is what Sky News had to say on it. https://news.sky.com/story/uk-installs-record-number-of-heat-pumps-and-solar-panels-12939690 3000 HPs a month, but most will probably be on new builds.

I don't think there is a lack of skill to install them, lack of incentive, on the part of the installers maybe i.e. uncertainty. Here are the ONS numbers, since 2010, for below 4 kWp systems. March this year was around 38.5 MW installed. If we say that the average installed capacity was 3 kW, that is 12,800 systems installed.

5.5% chance is neither.

Well that was good. There are ways around the damp issue, but for that knowledge my palm has to be crossed with many pieces of silver.
