About why you need a buffer tank?

The larger SMA inverters used to have a relay that could be programmed to activate at over 5A. A simple energy monitor should be able to be hacked to activate a relay.

That is the ultimate idea. Run the 'virtual' generator at fixed output and at best efficiency constantly. There may be better ways to do that than though variable pricing. If each house in this trial displaces say 0.5 kWh, that could easily be done with a very small battery system. Shift it up a layer, a larger battery at the local substation. There will be a point where the substation and recharge/discharge efficiency is optimal, and that should determine the best placement of a system. If course we could easily add in thermal storage, even if just a 50lt water pre heater, or even a cheap storage heater hanging in a wall. It is too easy to want the best system there can possibly be, rather than a cheap and easy one.

You can, just do it via a buffer tank or thermal store and a mixing valve. The boiler will still condense then.

Not that I know of. A few people have made some. I think @ProDave used a large desk fan.

Welcome. If you are a practical sort of person, make yourself an air blower to depressurise the house. Will make finding, and sorting out leaks much easier. There will be some in very unexpected places. But remember it is where the air comes in from outside that is important, not where it exits into a room, that is just the physical symptom, not the cause.

Displaced, not saved.

Does not seem to be ridiculously high generation this week. Not sure that the dip on Thursday was, was that when Scotland and the Isles went caput? Or misreportting.

How large is your unfinished house? The exposed surface area is important as well. I know people that are spending £40/day of direct electric heating, it is nice sitting around their houses because they are 8°C warmer than my place.

Which you have answered admirably with absolutely nothing except insults. Really no point in engaging with you as you just want to exclude all the other generation methods that have been deemed to be renewable, not by my rules, but by the generation industry and governments. It does not matter if I agree with it or not, but if I want to play the grown ups game, I have to play with their toys, not yours. That is just life.

Not sure you can. https://www.legislation.gov.uk/uksi/1998/2451/part/D/made Enclosed pipes 19.—(1) No person shall install any part of any installation pipework in a wall or a floor or standing of solid construction unless it is so constructed and installed as to be protected against failure caused by the movement of the wall, the floor or the standing as the case may be. (2) No person shall install any installation pipework so as to pass through a wall or a floor or standing of solid construction (whether or not it contains any cavity) from one side to the other unless— (a)any part of the pipe within such wall, floor or standing as the case may be takes the shortest practicable route; and (b)adequate means are provided to prevent, so far as is reasonably practicable, any escape of gas from the pipework passing through the wall, floor or standing from entering any cavity in the wall, floor or standing. (3) No person shall, subject to paragraph (4), install any part of any installation pipework in the cavity of a cavity wall unless the pipe is to pass through the wall from one side to the other. (4) Paragraph (3) shall not apply to the installation of installation pipework connected to a living flame effect gas fire provided that the pipework in the cavity is as short as is reasonably practicable, is enclosed in a gas tight sleeve and sealed at the joint at which the pipework enters the fire; and in this paragraph a “living flame effect gas fire” means a gas fire— (a)designed to simulate the effect of a solid fuel fire; (b)designed to operate with a fanned flue system; and (c)installed within the inner leaf of a cavity wall. (5) No person shall install any installation pipework or any service pipework under the foundations of a building or in the ground under the base of a wall or footings unless adequate steps are taken to prevent damage to the installation pipework or service pipework in the event of the movement of those structures or the ground. (6) Where any installation pipework is not itself contained in a ventilated duct, no person shall install any installation pipework in any shaft, duct or void which is not adequately ventilated.

Like our rules that force some people to take the risks of fatal illegal routes into the UK. Costs more and does not work.

Does not answer the question I asked of you. You are doing a Robert McNamara "Never answer the question that is asked of you. Answer the question that you wish had been asked of you"

We will all pick vehicles that suit our needs. I currently need a vehicle that can easily do 300 miles, at very short notice. So no BEV for me. Have been looking at the fuel consumption of hybrids, and for my driving profile offer little advantage, if any. Now if I still lived in within the M25, an EV would be worth while, though I would probably get a RangeRover "because they are safer" and hang the daily congestion and ULEZ charges. I actually had a GM Corsa Automatic when I lived there, and lived to tell the tale. Thing is, technology changes, even existing technology. We will get BEVs that can be charged in a few minutes, can do 300+ miles, cost the same as existing vehicles. We have to resist the knee jerk reaction to every price shock that happens. The stone age did not end because of lack of stones, personal transport will cost about the same in a decade as it does now, as will energy prices. Worth reading up about the Simon-Ehrlich wager.

Try a Google Image search. Found this. https://www.amazon.co.uk/Micro-Relay-20amp-Automotive-Motorbike/dp/B076H3NSH6

Or they will just increase the VED from the currently proposed £150/year. Still got a long time till all vehicles are electric, think we are at about 1.3% at the moment, around 370,000 out of about 30 million. Plugin Hybrids are just a little behind at 346,000.

For how long can we look at your hole. kWh you (expletive deleted).

Been using it for years, well actually use the main site where the proper data is. So to save myself time, and as I am not your secretary, if you search on here you will see a fair few charts I have done that analyses the data. This is why I know what I am talking about, I have been doing this kind of research for nearly two decades. Now if you want to learn about what you are doing, listen to this weeks Monkey Cage. No need for me to say more.

Have you been following COP15

Shall we let the striking NHS not pay the insurance cover and let anyone be a staff member. I think the real problem is that when these bodies are set up, usually with the best intention, the wrong people are asked how it should be done.

There is quite a lot going on at the moment, mainly tidal flow as it is cheaper. Tidal lagoon is probably the next best, but still a huge investment, and if you thought the environmental legislation was hard on self builders, just imaging what blocking the sea is going to do. Quite simply, today, we have two very viable, and cheap to deploy technologies that are well understood. We just need to get on with installing them. As I was walking back from Mousehole towards Penance, I could see the small wind turbine at the college site. About a half a mile to the left if it is a radio/microwave mast. Twice the height, higher up, and much more visible. For a relatively small cost, the college turbine (think it is 100 kW) could be changed to a 1 MW one, it would still not be as prominent as the microwave tower. Planning will never let it happen.

Can you show me the times when there was no RE generation at all. Then it is just a matter of scaling. You need to back up assertions with evidence, not half backed opinion.

What happened last winter when you had a similar problem, did you change some pipework about? Has a sensor fallen off somewhere, are all connections good? Mild weather coming in on the weekend.

You really don't understand how the energy market works do you.
