My central heating pipes are currently all in 8mm copper microbore. The flow and return go from the combi coiler to a manifold(?) in 22mm copper then branch off on 8mm to the individual radiators under the floor.
I am thinking of buying a plinth heater for the kitchen which has 15mm connections. Am I ok to tap off the 22mm flow and return for the plinth heater in 15mm for connection to the plinth heater or will this draw heat away from the rads? Would I be better tapping off the flow and return before or after after the connections to the rads or does it not make any difference?
Boiler is a Vokera compact 25HE. Only 4 small radiators at the moment.
Thanks for any help
