I made 200 links didn’t take too long once you get the hang of it. I have some bits of rebar kicking about you can try

Got it from eBay, it’ll do up to 14mm bar ill sell it if your interested but I’m a few miles from Cambridgeshire as I’m near Norwich

I had similar issue, ended up buying a rebar bender and making my own. It worked out quite a bit cheaper than buying ready made links even allowing for the bender

Yeah 100mm with pipes stapled to insulation. Spiral pattern with 150mm centres

screed above is a waste of money Mines very similar to JohnMo except I have pipe spacing at 150mm. I used EcFlow fibre reinforced concrete. it heats up much quicker than I expected and I get away with low flow temps, highest flow temp I’ve had is 29 degrees.

Yeah double garage with 2.4m doors can’t get the straps on the inside though due to the double thick block work piers

Just had a thought, could I strap the trusses to the piers instead of strapping the wall plate ? As the straps are to prevent lift, a twisted strap wrapped over the trusses and screwed to the concrete piers should achieve the same result if I’m not mistaken

Yes potentially the straps would then be over 2m apart though, and I assume the straps and screws would need to be stainless steel ?

Has anyone got any suggestions on the best way to affix the wall plates above these concrete lintels. obviously I can’t just fit the normal straps down the blockwork due to the piers.

Crikey, is it cold where you are ? mines been turned off for 3 weeks and the internal temp hasn’t gone below 19.7 it was 23 this afternoon

Depends on the heat pump I think. I can honestly say my Veismann Vitocal is very quiet, I can stand right next to it and not know it’s running other than by the cold air coming from the fan. other people have also remarked on how quiet it is. It faces my neighbour and is 6 meters from the boundary, his oil fired boiler is considerably more noisy, he has never heard my heat pump running.

So how are you supposed to fold the DPC up into the ICF block ? Surely when you pour the concrete it’ll push it down. Seems overkill, especially with an EPS raft

He can’t move the door over because of the stairs

I think it’s normal to just lay the ICF blocks on the overhanging DPM, why add another one ?

Thanks @Nickfromwales Well i commissioned it so could be my mistake. we have a heat pump so the water usually around 45 to 46 max I’ll take the knob off and check
