How to control radiators in a 1 pipe hot water system
I have a hot water system originally installed around 1955. It is a 1 pipe system with Venturi tees. I am tring to figure out how to cool down the radiators in the front of the loops. I have been told to use TRV's but now am told they will not work on my system due to the Venturi tees.I have 2 loops with 1 1/4" mains that tee from a 2" main. There are 15 radiators on one loop and 13 on the other. There are about 4 radiators on the front of the first loop that make the rooms to hot. Any suggestions?
