OK so that all makes perfect sense now looks like a good location with good outlooks. I will give it all some more thought now I get your objectives.

Looks like a great project can we ask a couple more questions: 1. Does moving the living space upstairs bring anything else to the party - EG better views, neater connection with the garden, and what are the downsides - is this your forever home or just a stepping stone on the path to it, have you worked out the long term implications of life one floor up - should you include a lift? 2. Do you have any planning / structural implications for all this work EG - change of external material, building footprint (extending too much), foundations able to take the additional load of second story.

Sound like there is a gap in the market for competitive products who can better the price point. Its only electronics after all but perhaps they need to avoid the complications of the Home Assistants - I wanted to integrate them into my home brew system but decided that the 988 page standards doc was better left alone and to stick with If This Then That only would be simpler.

Yes I see the cooled cases are not yet available so I will await one before stretching it.

Didn't bag one of the first batch but ordered this back in October, so very happy to see it arrive just now. This will be the core of the HA system for the house alongside an array of RPi PICO Ws that will run all the remote sensors and any actuators we feel we need. Lets see if I can squeeze enough time this afternoon to get it up and running and put it through its paces.

Not sure anybody with any sort of leadership charisma has either. If they had (both Charisma and thought it through) they would probably have risen to the top and we would be following them down the road of really solving the problem. As it is we follow the leaders we have more from a sense of bemused curiosity about what great big; blunders, errors, failures, cock ups and wrong turns they are going to make next than anything else. It's our fault though because as Jefferson said: “The government you elect is the government you deserve.” So to somewhat massage a phrase from classical antiquity 'we are sheep led by donkeys.' Time to become more like the lions and start snacking on the donkeys perhaps.

Yep - try it with your eyes shut if you want a real balance challenge - I would have fallen over 5 times filling our kettle!

If everything was IoT (Internet of Things) it could all be controlled by a remote system. It could even have look ahead capability to get ahead of the weather and be self tuning to the insulation / decrement delay.

You world need to surround the TV with radiant bars and reflectors then it would work provided you could stop the TV melting at the edges!

Does his mum need some tiling done or does she think tiling is a more reliable career than games design?

The sunamp system has to be a winning idea, it's just it seems not to be implemented that well as it stands give this and other threads but still not fully put off.

Glue (probably a PU would be enough - it's pretty good in shear) would help as well but perhaps too late now.

I notice that they are offering a 10year Warranty on the heating element in their latest marketing material. Looks like the OSO is about half as good as the Sunamp in heat loss terms ( OSO (150 Litre): 1.2 kWh/24hr (source) and Sunamp 150 0.67 kWh/24hr (source) so if you charge it each day on night rates @ 20p/kWhr the OSO cost you 24p / day (£87.60 PA) while Sunamp costs you 13.5p / day (£48.91 PA) and in a passive house you get less unwanted warming and no plumber calling every year to check your system over and re-certify. Sounds like a good plan. Looks like element failure, even with 10 year warranty, is still a return to base, no heating (although you have two units so not so much a problem for you), challenge though - which sounds like poor design at the very least - why can it / they not be pocketed one wonders?

When it was working did it do what it says on the tin? If it did then you wonder why, in the forth manufacturing age, it cannot be built to last. We are still on track to get one but the more I read the less I like the idea.

That is around 50 times the WHO limit (5 µg/m³ since 2021)

Yep that should do it as long as you don't have vast holes.

Not necessarily so... if you choose the same axis as the fan blade's rotational axis what are the implications?

But in which / what axis!

Rich beyond the dreams of avarice.

Right to light is not taken into account by planning IIRC. Just keep very good notes of everything as in the end it could end up at court where you neigbour can request compensation. If they have not allowed you to make appropriate measurement they will get less out of the judge one would hope.

You managed all that in 2.5 years since you were 17.5 when you passed your driving test. Presumably the bans were not 1 year each!

Is the control algorithm not IP protected as you would need that to reliably control the phase changes along the flow pipe.

Very frustrating. We want to go Sunamp but I still worry about reliability. We will only have one so no redundancy - two seems like overkill and we would need to stack them and getting a block that heavy up on top of its sibbling is a problem.

And avoid getting too close to the ends of the beam, as in stay several depths from the end EG 400mm plus if they are wooden joists the supplier will have a drilling chart you can use.

Neither did they allow it for this build they discussed this at the end as you mention, bit of a dig by Kevin about the problem with the DNOs - so although they had the energy for export it could not be. The house does generate the 4 times but the DNO cannot take it away - ridiculous. I guess you need to find a way to keep stacking up 3 phase connections and all the standing charges that demands to make this work.
