If you had 100 metres of head, at a flow rate of 1 litre/second, 95% efficiency you would only have 932 W. Trouble is, pico-turines are not very efficiency, they are like small windturbines.

Does it matter

Yes Press F12 to bring them up on the screen. But you do only get one undo, which is a pain.

When you get a mortgage on a new property, they send a surveyor around, there must be independent surveyors that know about windows.

Are some EU mainland companies not delivering because there is still uncertainty about what is happening next month?

About half the size of my house, put a second floor in and it is bigger. I need a new shed, but it is about 3 m by 2 m.

We all love an Essex Girl, frequently. (though I thought she was from Hertfordshire)

With a bit of plumbing and ducting it should be possible to make it just like a real ASHP, with the benefit that it can also do the MVHR. All I am after us a box that draws in air, extracts the heat, which heats up water. But small. Because of the low heat loads I need, I don't think short cycling would be a problem, so no need for a modulating unit.

Make it a closed loop system with a couple of heat exchangers.

Was in a Kent cafe where they had never heard of a ham and cheese toasty. "Looking in the wrong place" I quipped.

But I only need 17 kWh/day. It is really about getting a small heat pump, unless you know if a 'traditional' one that is 2 kW output.

I liked the dark haired one. I still wonder if Baby Spice tastes of prawn cocktail crisps. Not sure if that is a good thing.

If you treat that unit like a monoblock ASHP, rather than just a water heater in a cupboard. Then it could be swapped out like a traditional one. That is my thinking on it for my place, which don't need a lot of heating.

Re Steps. I had a pair open up on me. Hit the deck with my left are underneath them, right foot twisted between two bottom rungs. Trapped like a goodun. Broken arm and several broken ribs. 18 years on there is still a painful spot on my left arm. The plumbers on the site were impressed that I turned up the next day and carried on working.

Vacuum panels, 0.004 W/m².K Can't get better. Except cellulose is probably more practical in s building.

I have wondered about getting one and modifying it to do space heating as well. My heat and water load us about 17 kWh/day in winter, drops to 3 kWh/day in summer. All I need us a very small ASHP, which these are. Not sure who makes a very small unit as the cost us greater than the benefits at the moment.

I went past yesterday and there was no one on site, but more work had been done during the week. There is usually some activity there all the times I have past it. But you could take the opportunity to call in at MacSalvers at Pool.

Yes, but as I needed it for my job it did not matter.

There are strict rules about burning waste material, may be worth checking up on them. https://www.ofgem.gov.uk/publications-and-updates/waste-wood-burning-right-wood

It is really to do with minimizing mixing, the laws of thermodynamics stay the same.

The Part P I did was limited scope, is that what you are referring to. If I remember correctly, it was set up so that PV installers could wire in an inverter, plumbers could do a boiler or shower, kitchen fitters a cooker and move some sockets. There was a lot of general safety stuff and testing. All very basic, but sensible.

Take your pick. https://www.test-meter.co.uk/multifunction-testers/ Have you documented the installation method? Or just plug it in with a very low amperage fuse in place. Or, lick your right index finger and flick it across the earth and neutral. Get a sparky in.

No. I have been in many, worked in a few too many. This may be because of the much higher airflows, and the need to fit removable baffles. Then there is the space issues, floor area is a luxury that chefs don't have, so it is no good wasting space for a fan unit that can go outside. A commercial kitchen is not like a domestic one, clutter, or anything that is not used all the time, including staff, are got rid of, rapidly. Another reason may be that kitchen designers are not very creative, the equipment has not moved on in the 45 years that I have been involved in it. Still have the same useless benches that are difficult to clean, sinks that are too deep, shelves at just the right height to smack your head on, fridges next to ovens, ignorance and egos larger than the shop signage. I often wonder why I do it still, it is a mugs game.
