ASHP & triple glazing

[Joeboy]

The bottom half is done, all went well. I messed about with the IR thermo but the real surprise was putting my hand on the plasterboard. On the completed sections palm forward I feel my own blood heat and it was cosy. Moved onto a unfinished section and it is properly cold in comparison. Can feel the heat being taken off the skin.

On completion this will be over 12 sq mtrs of heat robber switched off.






The 1500W charger supplier has been in touch from Shezhen. Took a bit of back and forth to get across the odd footing voltage of Pylontechs. I think we managed to settle on a 30A unit @ 50.4V. They didn't off a midground below a standard 16S system (54.75V).

For reasons mentioned earlier I personally wouldn't recommend Vermiculite as it is hygroscopic. I used to use it for retaining moisture when incubating reptile eggs, it's also sterile for this.

If you should happen to want more of it.... I cannot get rid of the stuff quick enough. We use it for transporting lithium batteries offshore. When the tubs come back, the vermiculite is thrown out.

Free to a good home.

I have a feeling that it is good for mixing into home-brew potting compost etc. Yes: https://horticulture.co.uk/diy-potting-soil-recipes/
where can it be collected from? Far NE I guess!

Hell yes! Keep me in mind.

We used to own a granite prop with lath & plaster. I actually remember the relief when we sold it and upgraded to a build 80 years or so younger.

The wrong side of Aberdeen for most folk.

I will keep a stash. If heading this way, feel free to let me know.
Joe, I will ping you a message soon. I will see how much is currently in stock. It's usually a few barrels worth.

If I was a lot closer then I'd be taking a fair bit of the vermiculite, it's great for sub irrigated veg and fruit beds.

Minus 9 here at the moment. I think we agree it's a good HP stress test?

6.4% of the heat generated in the 24hr window went to defrost cycles. Now we know what minus 9 looks like for defrosting.

There is also a legionella cycle in there so pretty much a worst case scenario? Heat curve set to 0.4 and thermostat set to 19 degs. Outdoor humidity is a dry 45%.

Looks good, just shows what a proper install can achieve!

Edit 1hr later the vermiculite is dissolving. Use only in dry areas kids!

Vermiculite will hold upto 4x its weight in water apparently!


We have just ordered some bags of perlite. Your idea may be the perfect solution to insulating a small cloakroom that we have in the corner of our property that used to be the old outhouse, 2 external walls, 1 of which is partly a single skin brick only, where the old doorway was blocked in.
It was not internally insulated when the rest of the house was done, nor was the upstairs bathroom presumably because it would have required ripping out the suite, plumbing and tiling.

This particular room, despite an adequately sized radiator, doesnt really get above 16C. But it does have voids behind the plasterboard and no tiling up to the ceiling.

If it works and doesnt cause damp issues great, the room will have been barely touched and not decreased in size.
If it doesnt work and water tracks across then we end up having to rip it all out and do it again, but would have had to do that to insulate the other way anyway.

My cheapo thermometer stuck to the outside of our bedroom window is reading -14C right now. How accurate it is, i dont know but we are in a valley.
Google seems to think its -10C here, met office -9 and xcw -5C.
Our cop was down to 1.86 when i checked last at 3am, and the outside heatpump sensor (in the ASHP housing) was reading -9 at that point . Its still toasty and warm in the house.
You wouldnt have a clue it was even cold out.
