We are considering having our house rads and hot water system replumbed so it's not buried in the 1970's screed that it is at the moment. The cement progressively eats away at the copper if it is not wrapped in Denzo tape (no way to tell without digging up the screed).
We are thinking of replacing our ageing oil boiler with a heat pump which means we will be on mains pressure -significantly more than the gravity feed tank we have at the moment - which will make a leak even more likely.
Apparently some people in bungalows have a put in a piping ring-main in the roof void with vertical drop-downs in each room to the rads, or wherever hot water is needed. I imagine that 2 storey houses have a water plumbing system around the first floor, so having piping out of the screed and above the first floor is perhaps not unusual.
Is this piping ring-main in roof void a bad idea, if so why? And what piping would be good to use? Is multi-layer piping (plastic and aluminium) the stuff to use?
Any help much appreciated!
