Or how they are going to make it harder to build house, probably. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/590463/Fixing_our_broken_housing_market_-_accessible_version.pdf Only 109 pages long

Yes, basically true that a heat pump just cools one side and heats another. If the temperature differences, within the working range of the refrigerant gas, is equal, then there should be no difference. In practice there may well be a difference, but that could be caused by the plumbing side i.e. not capable of pumping enough because of UFH pipe restrictions, surface areas not large enough for the temperature differences, the fact that cool air falls to the floor, warm air rises which will effect efficiency. That sort of thing.

So do I, there is something just wrong about not going upstairs to bed.

Te reason that there is a difference in name place capacity is because of the relative differences in temperatures and entropy. Probably find that if you plot on the Kelvin scale those difference diminish and the only thing affecting it is the entropy caused by humidity.

PV/T = C Where: P = Pressure V = Volume T = Temperature C = Constant (this is for an 'ideal gas', but good enough for this) So separate the the working of the Heat Pump (Carnot Cycle, you can't get better) and the Plumbing, which is just where you want the energy delivered to.

Ideally, in my mind, what is needed is something that charges up on the lowest CO2e emitting power source and only discharges to offset the highest CO2e emitting times. This would require some central control and demand modulation, but should not be that hard to do.

Basically sums it up. And you end up with flat batteries. I know that with some sophisticated control and wiring that a system can cope with sudden grid disconnect. I designed such a system 15 years ago, but realistically it is not viable. What is viable for unexpected, but frequent power loss is a cheap generator and an extension lead or two. If your gas central heating needs power to work, put a plug on the end of the lead and plug it into the generator.

I am seeing that dodgy investment arithmetic again. If you went out on Monday and invested £4000 in United Bank's fixed rate NISA/ISA, after 5 years you would have £4350 tax free. If you went out and bought a battery storage system, after 5 years you would have £0 plus any savings. Worth bearing in mind that the last 3 weeks I have used less than 100 kWh. As most of that is during the night, so the cost is about a 3 quid a week.

Never heard of that problem, it has never happened on an PU moulding machines I have ever used. If only the industry knew of a cheap, non flammable, low environmental damaging liquid that could sort it our if it ever happened.

There are other schemes for second hand houses I think. Really odd the way people see house prices. They often see it as defered income, like a pension, except it is no direct cost. Keep someones mortgage repayments the same, but tell them their house has dropped in value, and the feel cheated. Up the mortgage repayments but keep the house prices rising and they feel winners. Tossers.

Doesn't that just push the asking price up. So really like a false discount.

You lot don't know what South is.

The woman that did mine claimed to be a chartered surveyor. Probably why she was reduced to doing EPCs

Or completely ignore it and get the hump when it is pointed out that they have not done as instructed. When I used to fit health clubs out and had to get builders in to do work, I often got the impression as they were looking at the job to prepare a quote, they were already looking at ways they could cut corners.

Stop complaining, you pay £1.192/m3 for foul water, I pay £3.4150/m3.

Just pulled up the EPC for my house, I had forgotten that they had doubled the floor area. If I correct that, but use their figure of 289kWh/m2 I still get a nonsense figure of nearly £2500 a year. Cost me about a fifth of that.

Are these people the brokers? https://c-r-l.com/

They have a new design that seems to have overcome the performance hit, in fact they claim that it increases the performance by 2%. The are just glorified Dysons, but probably cheaper to use when using the kgdust/kgair measure.

There is a company down here called PAL that makes venturi air filters for helicopters. Meant to stop the dust getting in the engine but still allow full airflow.

They should be using more energy as the boiler will have a lower efficiency than resistance heating.
