Jeremy, who used to be on here, has excellent notes and a spreadsheet that will help you achieve a well-balanced system, which I have used several times with great success. I will have a hunt for them and post later. I suggest that you use a Co2 monitor at the same time to check that the air flow is high enough. There are no flow rate calculations in your spreadsheet

The formula you need is Flow Velocity (m/s) x Pipe Area = Flow Rate (l/s)

Thank you kind sir

You can have low carbon and zero carbon, although the latter needs some offsetting. Some concrete has liquid CO2 added at the final stage. Please note: China has emitted more carbon dioxide over the past eight years than the UK has since the start of the Industrial Revolution. Between 1750 and 2020, the UK emitted 78 billion tonnes of carbon dioxide into the atmosphere, compared with China's emissions of 80 billion tonnes since 2013.

You will be surprised at how much more productive you will be with a staircase compared with a ladder. Tradespeople, if you are using them, will love you.

That's just architects spending other people's money.

I have listened to them all. His conclusion is that planning needs to change, but he's not sure in what way. Buildings do have souls and that is NOT how they look from the outside. Architecture is not just about how something looks, and IMHO that is the least important aspect, for homes it's more about its function and the niceness (health and happiness) to live in and live with.

Did a job some time ago with floor-to-ceiling patio doors. Used solid foamed glass under the frame - https://www.foamglas.com/en-gb/products/

Does anyone have a copy of Residential Energy: Cost Savings and Comfort for Existing Buildings by John Krigger, that I could borrow or buy?

You are correct to say that you should use dichloromethane and yes we (I am anyway) are listening and soaking up your knowledge.

Thanks for your reply. Hopefully, your temperature data log will have periods with and without the recirculation pump running.

Following with interest. Do you use a recirculation pump for a bit of time (~30 mins) after a heat cycle?

Yes, ideally, you need to keep them in a humidified cabinet or a humidor, although I think cigars need about 70%RH, filament needs less than 45%RH

Ground Trax make an excellent range (called Cellular Pavers) including good advice about how to install. https://www.groundtrax.com/

There is some better stuff available. Will post a link when I get home later.

Andrew Jones is the man. Call him for FREE good advice

It doesn't cause any problems with shampoo/hair, in fact, it will save you money because you will use a lot less. Jeremey, who used to be on here, even did the calculations to show how much money he was saving per year.

someone gets pregnant during the build

Why not someone similar to this? https://www.mikewye.co.uk/product/foam-glass-insulation-aggregate/

Make it an insulated slab, foamed glass or similar then concrete on top. Do you really need a screed?

I agree, Jubilee (a brand name btw) clips are very good, but I bet that is just a bog standard hose clip.

Totally agree

So how do you keep rooms at different temperatures? Perhaps with an upside-down house?

The regs say "Install the infrastructure necessary for a FFTP", a bit of pipe is not expensive IMHO

I agree, you want the whole house to be the same temperature. If rooms are at different temperatures it will cause a draft between them.
