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.

Is that you with 44 (forty four) bricks - that's a lift if ever I saw one. the HSE would have something to say adding all that weight to a wooden ladder's rungs!!!!

Yes @Nic that's a great link - gets a heap of professional advice from @Carrerahill who has a degree in lighting design.

Willis heaters are like immersion heaters for flowing water so you just put them in the UFH circuit and away you go.

No they are roughly in line with those, when you include fitting and well below Internorm. We went with Norrsken - very happy we are.

I was getting the wholesale prices for the exact same kit as the quotes, they came in between £3.8K and £4.3K. I can get a cheaper heat pump and if I loose the buffer it comes down a bit more. Had a really good conversation with one of the companies technical guys today which went well on my side as I got a good impression for my control options and some of the limitations of the heat pump (Modulation depth). I expect they thought I was some rather odd customer asking questions about everything.

You could do without the grant for that or less. Full price ASHP £2.5k, cylinder £1k, bits and bobs £500. Not quite I don't think. I did some estimates of the equipment wholesale costs, my brother-in-law has an account at one of the suppliers, and its around £4k and we won't get MCS certificate. I do need to negotiate hard and see what I can get.

Yes I think the best so far is £11K plus (so minus grant we will pay £4K.)

I would love a quote of £10K.

Does that mean you need loxone to access ebus or are the ebus electrical and protocol standards published somewhere.

I think I want to somewhat follow in the Homely footsteps and use dynamic trading - such @TerryE and others have been looking at through Octopus to control the ASHP / UFH / DHW use and SOLAR generation in association with APIs like openweathermap for more than direct weather compensation and then some basic AI's at the outset to to optimize it while improving this heuristic functionality through data gathering.

I thought that 12mm of pink fire rated stuff was 30 minutes on its own with the grey being 30 minutes when skimmed. Perhaps we are talking at cross purposes somewhere or maybe I have wrong.
