Id suggest that Bosch's statement is driven as much by the wish to avoid reputational damage as wanting to sell something else. Installing in inappropiate and poorly designed systems, with the inevitable outcomes, has big potential to damage the brand.

I have nothing much useful to say, other than i did limecrete over foamed class downstairs in the old part of my house. Its very nice. Rest of house is on conventional rads, and runs off an oil boiler. Input temp to floor is 40c if that helps. Quite easily holds the room at 21c regardless of outside temp. 9 inch walls, no insulation. Though they are a very lightweight brick which, now they are dry, by any measure of logic makes it twice as good as a conventional, old, cavity walled house.

Any chance of explaining what this means in english? I guess i might need to be concerned, but have no idea what any of it means?

I did exactly this. Steel framed, clad in composite steel panels. Also insulated under the floor and up the sides to meet the cladding. Near perfect thermal envelope. Only messed up at the door way, but thats may fault for not thinking ahead. Same intended use. Not sure how it stacked up cost wise against the options though. But as an outcome, coudlnt have been better. Details here: https://www.garagejournal.com/forum/threads/my-gab-in-the-uk-thread.265998/

Assuming this isnt in scotland i think your are over thinking it. My understanding of the 30m rule is a new installation. Yours isnt "new". Its repacement of existing failed system. As you have found out, the EA say you decide if it complies. They will only come after you in the event of some massive drama/issue. My take would be you have complied with the GBR. If you are not happy to state that, get insurance against any subsequent costs coming back to the purchasers. It will be a couple of hundred quid at most. Problem dealt with, get house sold.

Surely you want the dewpoint outside the build up?

Except that vehicles are producing less than half that of burning wood.

Surely you wont know if its worked for very many years? Ultimately its an investment with risk attached with a VERY long payback period.

Your logic on the smell is sound. Meanwhile, back in the real world. Ive NEVER been in a house with a wood burner that wasnt immediately obvious as soon as you entered the room. And over my lifetime, that quite a lot of houses. The blurb available suggests that 35% of those particulates are from burning wood. Im happy to admit, i dont know if those figures are correct, but its a high number for something that for most people is for effect rather than genuinely used as a heat source. In my village every single house has a central heating system. But they all have wood burners too. Im the only one without. Im not one for banning things, and as i said, poison themselves if fine, but not me as well.

maybe a touch extreme. But doing it piecemeal is going to be a mightmare. If it was me, id have a caravan outside and gut most of it and do it right. Or move. Otherwise, fill up/seal all gaps, insulate the roof as best possible and call it done.

Last year i looked at an off grid house. You can get an "easygrid" set up in a box, so genny, solar and batteries. I was quoted £30k. Actual costs per kWh were way lower than where they are from grid if you ignore the capital cost. You know its a messed up world, where potentially going off grid makes more economic sense that being on the grid despite a nearby supply!! Factor in likely future rationing and price increases, and maybe its worthy of consideration when grid connections are in the 10's of thousands. Ive just been quoted £15k for a 3 phase connection to my barn. From a pole on my own land less than 100ft from said barn. With me doing all the groundworks. Needless to say, ive kicked that one in to touch.

Are they highly inaccurate statements? Every single house ive ever been into with a wood burner, you can smell it. That means combustion products are in it. And that includes the sub 2.5 micron particulates. Frankly i dont care if you want to poison yourself, but i do care when those activities caause me to suffer. Visible smoke isnt the issue. Its those small particulates. You cant see those. I get there are circumstances in rural locations where its probably not a real problem for others, but for houses connected to the gas network? Really?

All rather predicatable from a chap that sells woodburning stoves.

Increase the frequency or length of the floating sludge return maybe assuming of course the pipe work protrudes above the water line. What heppens when the sludge return is running? Can you see the crud going down the pipe?

Mine was 15k too. However, the exiting single phase transformer serves only my house and next door direct of the 11kv. So to have 3 phase, it needs a new transformer. So i can understand it will get expensive. They also claim it needs a new pole to carry rthe weight. Not quite so convinced by that. I think i'll have to do without. Im not paying for a new transformer.

As above, western power is now national grid. The electricity distribution (11kv?) runs across my field. My house and next door have a transformer on a pole behind the barn. Sadly, its a single phase transformer. If i want 3 phase, i need to pay for a new transformer. Just for me.

Dont think i will be doing 3 phase. Had to have a lie down after costings from National Grid. Shame as seemed to be some good advantages.

Thanks Thats clever.

It does indeed explain a lot. However, one thing i dont grasp is, if you are consuming 4kW on one phase, and exporting same from batteries, whats making thar decision to export and balance the incoming v outgoing? Is the the thing on his diagram marked "gateway"? If so, what is that?

I did option 1. As pic pic, allows an unbroken unsulating layer. Edit: I used composite steel panels, so no internal works required as nice white painted surface. For the pennies it cost, wack some underfloor heating pipes in while you do it. But dont let the BCO know.

Big subject. Fair bit of recent discussion on the subject here. Lots of potential to cause future issues, Id also use the period property forum, though some of them can be a bit hardcore!

Im impressed. Ive always thought living "light" was a good idea. I just cant do it myself. Ive no idea what i would do all day?

Sure they would. On a serious note i considered binning all my space consuming hobbies thus opening up my options on houses. Couldnt bring myself to do it.

I cant answer that question. Only you can.

Cant store all my cars in it though!
