Fine Tuning Radian Floor Heating

Posted by java_man (My Page) on

My apartment (1 year old) uses radiant floor heating (and cooling). The system has three thermostats but 7 zones. The overall design is quite good with one glitch - the master bedroom and ensuite bath are on the same thermostat. This is a problem for us because we prefer a cool bedroom but a warm master bath.

The manifold that controls the flow of fluid to the various zones is accessible. If I were to shut off the loop to the master bedroom while leaving the loop to the ensuite bath on, could I keep the bathroom warm while the bedroom stays cooler? If yes, is there any downside to doing it this way?

RE: Fine Tuning Radian Floor Heating

could you use the valve to reduce the flow on one loop without completely shutting it off? It's not designed for flow adjustment but you can tweak it a bit to get flow down. It will put more heat into the bathroom loop and less into the bedroom loop. So the answer is yes, this would " keep the bathroom warm while the bedroom stays cooler" and this is your goal: a bathroom warmer than the bedroom.

I'll let others with hydronics expertise contribute as to the impact of completely shutting it off,
