hopefully sometime this year ill be taking my open fed conventional boiler out and replacing it with a a combi boiler once im gas safe,but not 100% how the radiator set up works ,i know basically that the pipes running from the boiler go to the copper tank are flow and return .the flow pipe runs to the pump then to the 3way valve to either go through the coil in the tank or to heat the radiators up, then for the radiator pipes runs and T off to the different radiators around the house. but un sure about the return pipe from the radiator! .tell me if im wrong does the bottom pipe from the copper tank which is also the( return flow for the hot water) do i T into this and use this for the return flow from the radiators thanks
