Hi team,
I'm going through a whole house renovation, and just about to start on the ground floor. Oil boiler already replaced with a system boiler and heat exchanger as installers didn't want to trust the old pipe work to withstand pressure.
I've now worked out rad sizes and pipe sizes for running house at 50 degrees and so am working my way round replacing bits 1 room at a time. The old copper is still very thick and all on compression joints.
My main q is whether i replace the main branch downstairs which is 35mm with new 28mm, or whether I should just pressure test it and check for leaks? Would replacing it really ensure longer life, or do you think the older thicker copper and quality fittings should last?
Ideally looking for a heat pump in the future, hence the leg work now and possible need for pressure at some stage.
Thanks all very much (and sorry about the pic, it was more to show my underfloor insulation should EPC ask in the future!)
