Can shake glands, whoops, hands, bloody autocorrect.

At my school, the built in wardrobe, in Dormitory 3 was where it all went in. Bodmin and De Suza got locked in one night. Bodmin came out crying, De Suza grinning.

Two things. It was the disabled toilet, I feel qualified to use that, not all disabilities are visible. Second thing, there are 'Keep your Distance' signs up, maybe because Phillip Schofield is staying at his mum's near Newquay.

Get the angle right makes me bigger, or twice as handsome. Did manage to get 3 'images', but just made a mess. (expletive deleted)ing brilliant

I had a similar design, but in plastic. Worked well if I used the right fittings, squirted water everywhere when I used a generic male fitting. Always worth checking.

I assume this is screwed to the tap. Have you got the correct male insert (no sniggering at the back). Is the tap switched on.

Was it not 200mm from ridge and gutter and 300mm from the other edges? Been a while since I had to worry about it.

I was going to say similar.

All good science is tested on dumb animals. Should be a Government Slogan, just got to condense it to 3 words. @Adsibob is the slogan man.

I think you/they only need to know about heat capacity of materials, energy density, combined gas law and the difference between energy and power. Newtons Law of Cooling would be an added bonus (but then it is a bonus for the world). The rest is pipe fitting. Probably the biggest problem is controllers, too many on the market and no standard interface.

The only thing that may cause a real problem is if you cannot get your batteries close to your inverter. The reason for this is that the DC cables have to be large, AC ones don't. The general rule with ''renewable energy' installations is to keep all cable voltage drop to below 1% (I think this comes from a metering issue where placement of the meter can show different generation amounts). When it comes to pipework, just insulate it more than you think you need to. This can be as simple as boxing in pipes and filling with mineral wool.

They are frequently rubbishing heat pumps.

Exactly, one group is ignorant of science, the other isn't. It is how to educate the vast majority. The science and theory behind heat pumps is talk at secondary school but not reinforced often and then forgotten. Madcap ideas that skip the science and theory are reinforced ever day, even within the heating industry.

You say the floor is traditional stone, is there any insulation under it? You say the upstairs gets hot in the spring, how much insulation is up there. You may be better off heating your hot water with the heat pump when the sun is out. But if your PV is supplying your needs, not much in it. As for space heating in the winter, not much you can do, a direct electric boiler will cost you more. Your HP will almost certainly have a direct heater built in. That may be on permanently. Turn it off. Can you get some thermal energy data directly off the heat pump, that should show you how much energy the house is using.

They are mental then. I held my phone at arms length, the peaks in the middle is me breathing.

The smaller the temperature difference, the longer you need to run it. So within reasonable operating conditions, probably no difference. I think, as tried to explain in my previous post, the whole thing is a lit more nuanced than people think. The same us true for a gas boiler setup, not many of them are close to efficient, but when NG was tuppence a kWh, no one gave a (expletive deleted), which just shows how little the is understood. Yes, really needs a machine to do it, better than a plumber's mate.

Why not put a bit of insulation in as well, you know it makes sense.

In contract law, silence is not acceptance. But as usual, never simple. https://en.m.wikipedia.org/wiki/Felthouse_v_Bindley

@Onoff How well did your nettle tea fertilizer work?

Almost. You may get short cycling when close to the minimum flow rate, especially if you are running at the lower end of the temperature window. If the buffet/volumizer, and associated pipework is properly insulated, then there not many thermal losses. Mostly, but as you have found out, it is hard to get decent information, this leads to customer ignorance. Ignorance in the proper meaning. Trying to explain, via a sales or remote technical person all the nuances, when the basics are not understood, leads to customer confusion. Let's face it, many people still struggle to understand Economy 7, let alone the multitude of ToU tariffs available today. Terms like 'refrigerator in reverse', 'low grade heat', 'only work in a well insulated house' (how often do we hear that unqualified statement on here), 'they don't work when it is cold', energy and power constantly mixed up, and no explanation about what they are and what uses of the term means, and even the experts on the radio getting latent heat and sensible heat mixed up, just adds to the general ignorance. A first year science students does not learn any new science, what they are taught is 'unlearning'. All those simplistic, basic ideas and examples have to be broken down and rebuilt. It is why, after 120 years, the public really don't understand Quantum Physics, they had 400 years to badly understand Newtonian Physics, then get told it is wrong. No wonder there is distrust in science. We can create an effective vaccine in record breaking time, while still believing that Bill Gates is implanting microchips into all humans, and 5G masts caused COVID. Lots of education is not helping. There is a thread on here from someone that had never heard of a heating system that stays on 24/7, said it was ridiculous. I wanted to point out that most heating systems are in 24/7, just that during that window they may not be consuming any energy, and may, or may not, be releasing energy. Economy 7 is a classic example. It is on all day and night, the difference is that it only received energy for a limited period of time, it is always releasing energy. If it goes 'cold', that just means it is either incorrectly sized, or being used badly, nothing to do with the underlying technology. Explaining to a customer what the problem is, during an hours sales visit just ends in useless soundbites.

Or in Russia/China.

Possibly no need for a buffer may be more accurate. I am still of the mind that a buffer/volumizer is always worth fitting. They do have to be designed in from the start, not added as an afterthought.

It is a garage, so damp. And there is ply already on site.

Need a bog cleaner. Long hours, but as much heroin as you can handle.
