Not sure if this got on b4
Recently had a system extension during which plumber reveresed the heating system flow- new boiler, cylinder, pump etc. During drain down plumber did not change over valves on the rads. One oro two have old Peglers is the flow on these reversible. The main gurgles come from these rads.
Also TRV's are should these be on flow or return? Have sen conflicting ideas on this forum.
Finally pump speed - 1,2 or 3? 13 rads on system, Spuprima 80 boiler, house over two floors?
Any help appreciated
Tks
