(expletive deleted) you, I am switching it off, going to bankrupt the whole of the UK's power sector on my own.

FFS I am paying for your heating. But how many years will it take to cover the cost of your useless walk on glazing? That makes me feel a lot better.

Ohm's Law https://www.calculator.net/ohms-law-calculator.html

They could run it on CO2 which is a pretty good refrigerant gas, but generally only when it is in a critical state around 31°C, but if this pressure pump can increase that 30 atmospheres, then it is around 73°C, which is useful. We do make helium, in a fusion reactor, how they work. Not sure how much you get in 5 seconds though.

The efficiency is only for the compression part of a heat pump, it does not take into account the energy it scavenges from the heat source i.e. the air or water. Be interesting to know what the best scroll and piston pumps efficiency is.

Mine don't think. That would defeat the object.

Makes my legs twitch like a dead frog's.

That is for curing piles with an electrode.

Does it work like a pulsejet engine. Still relied on the Carnot cycle. Ultra sound cleaning caused a change of state in the cleaning fluid on the surface of article being cleaned. That is a form of focusing. Seem to remember reading about this 20 plus years ago, surprised it has taken this long to get this far. Not sure where all the helium will come from, it is a fairly rare gas these days, and we are not making anymore if it on Earth.

Keep things in perspective. You can easily work out the exposed surface area of a wall tie, and how many there will be. That, along with the length and the thermal conductivity o the material they are made from can easily be translated into a U-Value. Then look at what percentage that will be of total losses rom all other elements. In a similar fashion, you can work out the cost difference and compare it to the total spend on insulation.

You should also have a generation meter after the inverter and before the consumer unit. Have you checked that, and what does it read? Then divide the number by the number of days since the system was commissioned.

For 2/3rd of that money, I will be lube up wires, pull and jerk will all my might.

If it is not built yet, get rid of the hips, get more on then. But basically yes, standard trays around the windows. I think Velux actually do a PV system.

Why would it be removed and not replaced? £10 Sheet of polycarbonate would sort the problem if waiting for a replacement after a completely devastating failure though they tend to stay intact after shattering)

Just tell her the Cornish Stonemason is on his way drekkly.

No you haven't. You have a system that has an installed capacity of 6 kW. If it has only generated 2.8 kWh in a day, the I suspect that something is seriously wrong. What make inverter do you have? What size is it? Do the modules have optimisers on them? There is always a possibility that some of the modules (the proper name for panels) are not connected up, or have become disconnected. Let us get the existing PV working right first, then worry about a larger system and diverting power kW is power, kWh is energy. The difference is important.

To save the planet, I sent the wife back to her husband. Other wives are available.

Adding a second Willis is cheap. But adding extra electrical storage gives you flexibility, but is expensive and the cheap 4 hour window may vanish. Leaving you with expensive batteries. So is the overnight temperature in the house acceptable? Would a large thermal buffer tank allow you to store enough for the cold days? Can you divert PV, even if only a few hundred watts into your existing system during the day? 25p/kWh during the day is not that expensive, a cheap packet of fags costs a tenner, a pint about a fiver, and the coffee I am drinking at the moment £2.75. My car burns through 45 kWh in an hour when on the motorway. That is almost 7 quid an hour. If it was an EV and still used 45 kWh but was charged at 25p/kWh then that would be £11.25. but the distance covered would be 110 miles, rather than 60.

Should be alright then. I open my bedroom window at night, when I am generating humidity. Never understood opening them after the event.

Don't need to, but as an architect was invoked, we know with a very high degree of certainty it has gone over.

About a week's rent and a week delay. And the budget is totally blown, it would have been a greater % of the original budget.

Welcome There are quite a few threads on here about solar and batteries. If the search facility is not showing decent results, use Google to do a site search and it generally gives more targeted results.

Well not small holes. The main problem is because airtightness was vastly improved (generally) over traditional building techniques, condensation started to become a real problem. Because of the movable nature of gasses, condensation generally happens on the nearest cold surface. So windows first, then 'somewhere within the wall'. As timber can rot after a few years, there is more moisture in the gas we call air (a mixture of many gasses, including water vapour), and the warmer the air is, the more fraction of water vapour is potentially in it. To overcome this, a VCL is installed on the warm side, in the UK this means the inside. The rest of the wall is now only open to outside air, with its lower temperatures and absolute humidity, the actual grams of water vapour in every kilogram of air. By also being 'vapour open' to the exterior, as the wall warms during the day because of solar energy and weather variations, the smaller amount of water can easily evaporate away. But because there is now a trapped volume of air within the building, and one that has a greater absolute amount of water vapour in it, even if the relative humidity is lower, this has to be dealt with. Window trickle vents and extractor fans were the usual method. Whiles these work, the air changes are uncontrolled and spasmodic, and threw out the energy that had been put into the air to heat it up. So mechanical ventilation and heat recover is now fitted. This works best in a very airtight house and should easily recover the electrical energy to run them. So how do you ventilate your house?

Tell me about it. Only got once socket, on an interior stud wall, that does it. Just can't seem to find the path it is coming in.
