Well there you are then

You can get them for different thicknesses of board and double board.

That's as clear as mud. I installed a 4 bar wooden fence in front of mine, about a metre in front, but the amount of defrosting that occured after installing made me remove the fence a week later, be careful with air being recycled.

An English video by same person, but doesn't mention anything other than humidity activated? You do need to watch the mm² area, no use putting a small vent in each room, follow building regs for sizing. In Scotland they are pretty huge.

They still grow, not as much, but our resin grout is all covered moss at the moment, if you pressure wash at a high pressure the resin based grout can also lift out. So you have to be careful.

New build equals low flow temperature. You can use what ever floor you want. We have ceramic tiles in wetrooms, oak floor in lounge, hall and office all bonded to the floor. Carpet in bedrooms - carpet kills performance at low flow temperature. Not sure I would do wood in a kitchen, one spill and it could be time to get a new floor! We are 5 years since the wooden floor was laid, with no issues.

I would bring the cables to a multi pole DC isolator on the outside of the house, for ease of access in case of a fire. Then run the rest of the DC to your inverter. Run cables in service void but I would want something to you or someone else drilling a holes later and hitting a DC cable. So in save zone with metallic shield so something like https://www.screwfix.com/p/deta-tte-37mm-galvanised-steel-channel-2m/826VT?tc=TA5&gclsrc=aw.ds&gad_source=1&gad_campaignid=22599672207&gbraid=0AAAAAD8IdPyi10Bx2zrVz5Z9Lr6xcezkw&gclid=CjwKCAiA_orJBhBNEiwABkdmjHstK7DySAtkOoGd1V-4dnj9I9QLc64xIKDU339IXlACKlvaonv5AxoChkYQAvD_BwE

Think they have become, a little (or a lot) full of their own self importance, so many become a Think I would be sitting down with a solicitor to see what I can and can't do, before I spent a penny on any planning or remedial works. Is the building a listed in any way?

I have also found these through wall inlets look a bit nicer. https://store.beamcentralsystems.com/collections/mechanical-ventilation/products/dcv-intake-air-valves

If you don't need to airtest I wouldn't, you end up boxing your self into a corner. Especially if you live in Scotland? I would progress the way you are planning. Tried a couple of dMEV fans in our summer house - Greenwood were head and shoulders better than other fans I tried. And cheap enough on eBay. Remember you need to have all internal door under cut at the bottom for dMEV to work correctly. I would add a co2 sensor to main bedroom as well so you can fine tune your system.

Aren't you using this sort of back box with plasterboard, so no additional supports are needed?

Got to the bit where he started drawing and lost the will to live, fast forwarded now and sorry yes opentherm.

First on Google, video on page as well. https://heatgeek.com/articles/articles-home?p=choosing-the-best-smart-thermostat Pay wall is for AI features, but who needs them?

That's just an on off thermostat he is installing. Why bother spending good money to a fancy looking thermostat that had the functionality of a switch?

You'll have to look for yourself, think it's a video of that helps
