Any heating engineers - need input on DCH closed system water pressure and radiator performance

Did you get a 2nd opinion regarding the rad/s installation/s? it would be helpful if you could get some decent photos of the rad valves too.

No, not been able to get anyone out. Kind of gave up, as a lot of other issues..........and don't want to be having to disturb newly plastered walls. I ended up buying wiser TRV's and have these rads coming on 30 mins before others. They still struggle!

That would be great.
Thanks

So here we are 3 years down the line.
The radiators are superb with a nice even heat across the room with the benefit of still being able to use the wall for a sofa etc.
Because they are basically a 22mm copper pipe with aluminium fins it heats up really quickly and transfers heat to the room really fast.
Looking at the Kwh used consumption is down by 800Kwh per year but that could be down to the milder weather.

Hope this helps.
