Because they will, and are already doing so in some parts of the world. That came about from the old (late 1990's) subsidiaries. What was not foreseen, and reacted to fast enough, was the rapid drop in price if offshore wind and large scale solar. Because of this rapid drip, planning rules and grid connections are hampering the up take. Rather than piss about with subsidies/incentives, the government just needs to take planning restraints out of local authority decision makers (which they want to do). Money can be raised by increasing taxation on combustion technologies easily enough. I really don't understand why this is not happening.

Read this. https://www.aquaswitch.co.uk/blog/lcoe/ It gives a good insight to the problems.

You could coat it with a clear casting epoxy. The main problem is that epoxy is very good at crosslinking the polymers, which is what is wanted for strength, durability and stability, but makes it a bugger to stick other things to once cured.

Probably not an engineer. Probably Level 3 technicians at best. It seems odd that that to fit PV panels, though the MCS system, a qualified structural engineer has to sign of the roof structure, but to put quarter of a tonne of hot water above people needs nothing.

Very valid points. Especially this one, how often do we hear this. What model do you have, or can I borrow your unit when you have done with it.

Welcome. I visit Buckinghamshire every couple of weeks. One of these should do you. https://www.appliancesdirect.co.uk/p/iqool-smart12hp/electriq-iqoolsmart12hp-air-conditioner

Oh dear, you have not read enough Buildhub. To answer your question, it depends on so many things. The energy stored is simple to work out 0.8 kJ.kg-1.K-1. The power emitted or adsorbed is proportional to the exposed surface area and the temperature difference and follows Newton's Law of Cooling.

I don't think that gas is the long term problem, nuclear and storage are the expensive ones.

Just seen this from a week ago. https://news.sky.com/story/energy-future-paying-up-front-should-lead-to-tangible-savings-ahead-13390939 So are standing charges to go up?

Part of that process must be knowing the rules. I do fail to understand why a self built house is exempt, where an identical house, but built by a developer isn't. Almost like saying that no extra infrastructure is needed if you put some blood, sweat and tears into building your own place, but the professionals must have their profits gobbled up. I think it totally misses the point of community infrastructure, actually it misses the point of community.

What was the outside air temperature? What is the air infiltration number? What orientation is the new extension? How much glazing as a fraction of insulated wall? What sort of roof is there. Does it have 'always on' electricals i.e. home entertainment, fridges, tumble dryers? Below is my house temperatures. for the last month and for last week when it was warmer. Last week was 1.5°C warmer (mean), the house was 0.8°C warmer.

It is quite acceptable to lie in a marriage, as long as it it spare the other half's feelings. Says the guy who has never married.

Not what happened. The seal manufactures told NASA not to launch, but they still did. It was a failing of senior management that felt under pressure to deliver. Feynman at his finest.

Not read, in detail, all the above. There is nothing to stop you designing a forced air heating and cooling system, and then adding heat recovery to it. It is done already, but it is expensive. But why do you need active cooling, you can design temperature extremes out at the beginning. It will mainly mean you will not have huge windows, but will probably make the design cheaper to build. I am about as far south as one can get in the UK (not quite the Lizard Peninsula, but close). Only only in 20 years have I had to temporarily mitigate high OAT. If it really does get too hot to sleep upstairs, sleep downstairs for a few nights. It is a lot cheaper. Slightly more expensive option is to book into a Travelodge, but check they have Aircon.

But greatly reduced output during the summer, if you want to use them for cooling. This is the project for a 1kWp system, South facing, by the sea in Penzance. First screenshot is vertical, second is horizontal.

Best to fit condensation drains of you can, it gives you the option to run them at a much lower temperature if you want to, though you have to be careful if running UFH(UFC really) at the same temperature, but if you have a reasonably sized concrete slab, it may take a few hours to drop the floor temperature to the dew point.

I can see two problems. Energy loss Condensation risk Energy loss could be counteracted by improving another element i.e. improve the window. Condensation risk is a lot harder and would need some more information. What is the wall NSEW orientation. South facing would probably not be an issue, North almost certainly is. You only need a relatively small amount of insulation, maybe 50mm, to stop the wall from dropping below the dewpoint temperature. You should be able to model that section fairly easily in 1 dimension to get an idea of the scale of the problem. Failing that, just fully fill the cavity with insulation, but be wary of any existing cavity ventilation already there n place, even if it is already obscured.

I suspect that the compressors of most fridges/freezers are made by the same, small, group of companies. Unusually get about 10 years of use out of the cheapest fridges, but at work, the expensive ones don't last any longer. As the weather is getting 'fresher' (as they say on the weather forecast), you may find that the problem goes away, if not, consider buying a new one. Also worth reminding that the sunk energy/cost of running a fridge is in cooling the stuff in it, not the air in it. So avoid putting in things like room temperature liquids if you can.

Can you get a fan to blow the room air across the rear. Fridges usually have a temperature range that they can be operated in, but it is rare in the UK to hit the minimum and maximum temperatures. How old is the unit? It may just be failing, you can usually tell as the internal temperature starts to swing wildly between warm and frozen (in the fridge part) and you can hear the unit pumping. It also pushes your electricity bill up a lot.

I had a condensing washer dryer, can't remember if it was a Hotpoint or a Candy, but I seem to remember that it used the cold water feed to condense the moist air.

In 15 years time you get a cheque for 30 quid. Not going to happen. How the mighty fall from grace.

How long did she sit on it before she got hot, sweaty and cross eyed. Leave it plugged in and you can play with your new stereo.

The physics of cement cohesion All answers are above. Good luck, it is a technical read.

Well yours is a lot better logged than EDF manages. I think there is already 7 days missing and not at the end of the month yet.
