Looks fabulous. How do they fish out the spiders in the end without leaving footprints?

For me planning a near-passive-house new build, the following quote suggested that a SunAmp model with UFH pump and maybe other parts of a UFH circuit included (I suppose an expansion vessel is unlikely?) may be arriving soon. A potential central-hearting system in a box. Could be ideal for my needs. "Forthcoming availability: Fully-integrated Sunamp HydrobloQTM incorporating system pump and other hydraulic functions".

Welcome. I have learnt a huge amount by reading the answers to others questions, so I look forward to yours.

As far as I have read, air-based ground-source heat-transfer systems suffer from nasty microbial things living within the underground pipes. One correction. As was mentioned long ago by @JSHarris, at the depth of those pipes they are not tapping geothermal energy (from from the original formation of the planet and from radioactive decay of materials). Its heat from sunlight that has warmed the ground and soil beneath. Top down not bottom up. I also wonder if the irrigation water would be from a sustainable source.

A UK supplier of Nickel Iron batteries? https://www.bimblesolar.com/batteries/nifebatteries

@JSHarris Nickle Iron?

Superb. Exactly what I am planning. Did you put them anywhere else? Did you try them in any ceilings (I am tempted)? I wonder did you use a lighting designer is this your own inspiration?

Wow, that looks great, @lizzie! @lizzie, in the second photo, what are those linear recessed lights? I am after something just like that. And is that a sun pipe?

Oh, are they crappy. I was thinking of copying @lizzie and using those on my build. Why crappy?

I have had the opportunity to drink beer much older than that (more than 10-years in fact) and it has been fine.

Impressive progress. My plot will need piles so i'd appreciate the chance to visit on the 17th July, if that's possible.

For ease of reference, (current) list of timber-frame companies exhibiting at NSBRC https://www.nsbrc.co.uk/exhibitor-search/?category=Timber+Frame.

Would that be the BCO officer selected and paid for by the developer/builder?

Yes, appalling. When the party that has a vested interest in a pass chooses the one to be tested I think that it is a stretch to say that testing is done on a sampling basis. The sampled one clearly is not representative of all. An awful state of affairs.

+1 me too.

Hi @Brad, welcome to the Board. I would welcome some advice. Sent you a PM.

Welcome @Tosh. Impressive progress and an exciting journey ahead. Maybe consider starting a blog?

@readiescards is that an enthalpy heat exchanger?

Welcome, @IAMJAMESMANNION! You've come to a good place.

That's a fascinating insight! Shows the margins for error that a structural engineer must by necessity allow.

SunAmp's official announcement of their UniQ range is nigh. Its next weekend at the Fully Charged Live show…

That might fit with what I was told then. That margins are tight on the windows themselves alone, even if they are concealing a discount from you perhaps its not huge.

@ultramods when I visited a certain timber-frame manufacturer recently, I discussed the question of window pricing and discounts. The sales person said they make most of their margin on the installation part not the windows themselves. I am not sure if that's fully true or just spin. Its probably a combination of both. I came away with the impression that I would be following @ProDave's approach for mine. Negotiate my own window price and take it to the TF manufacturer. And if the TF company wont install my chosen window, which is highly likely as that manufacturer had only a single preferred supplier and refused to install for anyone else, then I would contract the window supplier to install. I am hoping that in either case that its a design-and-install approach which simplifies the VAT. And in each case I am handing off the measurement/specification risk to one or other party. I am not sure if this is a good approach but it is my current thoughts.
