Combining Zones

Colin_3 Member Posts: 1

I have two zones in the same area competing with each other. I would like to combine them. given that the circulator has sufficient power.

The main ring is a 1 inch loop with Monoflo Tees off to each radiator. The second zone is a closed loop of two baseboard radiators on a 3/4 inch closed loop. Both zones are hot fed at the same manifold which contains a pressure tank and air bleed, the circulators are on the return side of the loops. I'd like to remove the return end of the 3/4 loop and T it into the 1 inch main near the return end pump. (I will be using the now vacant second zone foro upstairs).

My questions are:

1. Should I consider a return monoflo where the 3/4 loop T's into the main? And can you get 1x3/4 Monoflo Tees?

2. The radiators on the 3/4 loop do not have individual air bleed valves How should I handle this? - If I must have bleed valves, since these radiators are now Tee'd off the main rather than being a closed loop, can I add them to a baseboarrd radiator or should I replace the radiators?
