Let's hope @MVHRDesigner is out there looks like they know their stuff.

Welcome Jon. This is THE forum for people like us. We are all nice people on here, well mostly! Why not start a new topic - 'Repairing the Sentinel Kinetic Plus' and share the story so far. Any ideas why it stopped working? For it to fail completely usually means a fault common to both fans - so the controller somewhere perhaps or it maybe that if one fan fails the other is prevented from running by the controller.

Was it an incandescent lamp or a LED. If the former then it is entirely possible that the blub going will cause a current spike. Triping both the CU and the fuse is unlucky but not impossible given the right circumstances.

Do you have a circuit diagram somewhere - it should be easy to work out where the GND goes from that!? In general - and I would not advise it without understanding the LV circuits, you can safely connect all the 24V grounds together PROVIDED you are not in need of isolation IE you may have an DC-DC converter in there somewhere that has isolation as a feature and the you would not want to bridge out that isolation by commoning the 24V GNDs. You should NOT directly (indirectly via failover switching systems and / or diodes might is possible) common the 24V positives from the various power supplies under any circumstances.

Or eat too much Avocado! I had some elderly relatives lived in one of the Wandsworth pre-fabs and they said they loved it and he was a construction professional - structural engineer. I stayed there for a short while when I was about 8 and had a great week - some of the kids in the street still lived in bomb damaged houses just along from it.

Yes Berkely Homes has also closed its very hi-tech factory in Dartford because it cannot make it pay, and they are volume house builders so industrialisation should be a natural progression. How come we managed to make this work in the 1940's but seem unable to make it work today with all the advanced technologies that could be applied.

HI and welcome to THE forum for people like us. We set out on broadly the same premise in 2015 and purchased a plot, with a semi derelict dwelling, with a view to doing something. Now we are getting towards the end - last 10% takes 90% of the time. Look forward to hearing more about it and remember - there is no such thing as a silly question.

What are the chimneys for though?

That looks very tidy that UVC.

Wow - How is that achieved? I thought PH windows were 0.8 or better - ours are 0.78. Not sure how you could construct a .15 window you can see through.

Have you looked at knock down and re-building in sections so you live in the remainder and move over to the first bit of build as it is finished and in the end you have rebuilt it? Would take some organising but might be made to work out.

Yes we purchased our windows as two packages, ground floor and first floor, as the total was over £30k to ensure we got the cover as we had to pay it all up front at some stage or another.

You can get what I suspect is the chip from mouser - https://www.mouser.co.uk/new/texas-instruments/ti-mmwave-iwr6x-sensors/ Alternatively if you just want to watch one person SEEED studio do a 24GHz (and here, apropos another thread this morning, I think we use a capital G although I have forgotten why) is one I have been experimenting with! It works OK but fine tuning is proving interesting - its a pain adjusting settings while lying down to get it to detect a fall!

@jimboflint19 Steamy is one of our most diligent sources of support in energy matters, indeed almost anything involving algebra, and as he will point out, I fell over this last week - and I should know better, if it is a unit named after a person then it is capatalised when used as a unit - so watts (not capitalised in a sentence unless it starts the sentence), because it is named after James Watt, otherwise it is generally not. Hence 24kWh = Twenty four kilowatt hours. More here: https://www.nist.gov/pml/owm/writing-si-metric-system-units#:~:text=NOT 250 mms.-,Capitalization,modifier "Celsius" is capitalized.

Does this include Domestic Hot Water?

I have one of those does the whole of our acre all on its tod.

Thanks one and all think that gives me a clear steer. Had forgotten to have a spare outlet for things like fill loops. At least now I can crack on.

Can you brush teeth with softened water?

Good thought, both, will include a run for that.

Just doing the first fix plumbing run's and wondered where we will need to run potable water, as in direct from the mains, as the house will have a water softener - Southern water is very hard! I was thinking of running it to all the bathroom taps, not the WCs, cisterns, showers or baths or indeed anywhere there is need to have balanced pressures on hot & cold, so you can safely drink the cold water there and to a filter tap beside the kitchen sink. We have great pressure and flow so I may have to condition the pressure before we split off to the softener and on to the UVC, I appreciate that the water softener will drop the pressure itself (looks like between 0.5 and 1 bar - which seems a lot but is what is quoted). I wondered if there is anything else I should use the hard water for!

We are not at the stage for the final stairs but to avoid the ladders we put in a cheap stair from Howdens to make it more comfortable getting around the building.

We need a spreadsheet for this lot, anyone up for experimenting?

That is then very weird. So the problem is here: Can you put a spirit level on the bath edge and see if it sloping towards or away from the wall - because to get behind the tiles it MUST be getting through them either directly - some tiles can be porous, or the grout - more likely. So I suspect the bath edge is slightly sloped towards the wall causing the water to flow under the hinge and behind that there is a hole in the grout that is letting the water through and behind the tiles where it runs down and out as you have indicated. Has the plumber take the hinge off to look?

How much water is there? Does it run even when not showering? Where does the vertical copper pipe run to? It's all a bit odd because to get behind the tiles there must be path in through the grout somewhere and that may be further up the wall than the base.

In the UK you can, if able to access the grant, get the job done for less than you can DIY it - so that's an incentive. True it is marginal, on ours the lowest quotes are coming in at a couple of grand over the grant - so cost to us being a couple of grand and I cannot get the core components, ASHP and cylinder, for that let alone the G3 certificate and the extended guarantees on the ASHP for that. So despite knowing that my fellow country men and women are paying for the grant, and perhaps therefore some over pricing, although given the MCS overheads these firms carry it is hard to work out how much this might be, we will probably go for this route and ours is passive class and in the SE.
