I've finally had enough of thermostatic rad valves not doing what they said. They either don't shut off fully or the temperature range is so far out they might as well not be on there. Rant over. So i'm thinking of fitting a 2 port valve on the flow to each rad and having it controlled by a descent calibrated thermocouple. The valve opens if it's below the rooms set point and closes if its at or above the set point. Firstly can anyone suggest a maker of 15mm 2 port valves. Also i don't think a soloniod valve would be suitable as they open and close so quickly they could cause excessive noise in the system. Also any other views on this idea?
