Suspended Timber Floor insulation - critique my plans please.

[marshian]

First time I've seen UFH done in that way so it doesn't result in an increase in floor height - looks quite neat

 

Given me an idea for when I redo the kitchen - unit space is at a premium and I would need to relocate the existing rad and so underfloor would be a much better solution - I now wondering if at my normal flow temps (32 Deg C at OAT of 0 Deg C) it would be enough to run underfloor at the same temp as the rest of the house rads

 

Now googling Alu Spreader plates

I think you'd have benefitted greatly from using alu spreader plates here, but your prep works seems good  You may need to raise the flow temp to get the results from in the areas without the pug mix, but that'll be down to trial and error I guess. Defo install room stats per zone as these will behave quite differently methinks.

 

Thanks, possibly but another expense I wanted to do without, so far the heat is nice and uniform across the room, even in the kitchen where the pipe and pug mix only run down the centre of the room. I managed to get 150mm PIR all the way under the cupboards with a lot of swearing and sweating....plus a bit of foam spray and gapotape where necessary, don't appear to have any draughts coming through.#

yeah it needed to be as the kitchen was staying in place and the room is one long area. It's definitely more work getting all the PIR etc cut, but the pug mix went down in one day and could be lightly walked upon 2 days later (dog obviously had other ideas wandering straight on top of it on the day). Did mean I could save some money reusing floorboards etc as well.

Just remember to leave spaces at the ends of the runs to perform a U turn  and allow for that in the m2 area you order up. 👍. 
 

Here’s the 1st install I used these on, worked really well.

not to take this thread off topic - I guess my next research job will be how many metres of pipe do I need to put down at 133mm centres with a flow temp of 32 deg at 0 deg OAT to match the heat loss of the room and can I fit that in the open area because I’m guessing no one puts it under units??

Ya. I run them tight to the plinth, and you can get triple trough trays instead of dual, to get 3 pipe runs per void.

 

Threads get detailed, even with the best of intentions lol.
