And the expansion vessel and kit is cheaper. Link to comment Share on other sites More sharing options...

A PRV that just terminates in the empty 5 or 7.5 L glycol container. That's all it needs to be tbh, so @ProDave you could just plonk one behind the UVC and have nowt outside. Your simply never going to blow off more than a couple of litres or so, plus nothing horrible or blue to discolour the landscaping outside.

ProDave Posted June 7, 2018 Author Share Posted June 7, 2018 Well it's all piped up now. As I suspected, it was a struggle getting enough antifreeze in. I filled at 3 points, the 3 highest points and only just got the required antifreeze in before finally topping up with water and bleeding. It's been holding steady at 0.6 bar for 48 hours, I guess 1 bar is a good pressure for final filling? I still have all the UFH pipework to lay and fill, UFH manifolds valved off at the moment. Should start laying the UFH pipe downstairs in a week or 2. 30 soldered joints and 22 compression joints and the only weeps were a couple of compression joints not tight enough 1 Link to comment Share on other sites More sharing options...

ProDave Posted June 7, 2018 Author Share Posted June 7, 2018 Most of the compression joints were unavoidable, things like valves, manifolds, the HW tank, pumps, etc. I think I only used 6 compression fittings just to join pipes together, and that was just to use them up.
