JohnMo Posted February 10 Share Posted February 10 Often thought about UFH control. Most systems are controlled on flow temp via a mixing valve, and with with room thermostat(s). Most use a mechanic mixer, some use an electronic mixer. With an electronic mixer, there is normally a temperature of probe on the supply pipe - but could you just look at water return temperature and then modulate the flow into the system via the mixer. So run a set return temp and modulate the flow temp going in. My thoughts are, it may give faster warm up times. It may automatically compensates for how much heat given off by the floor; flow/return dT changes, as floor to room dT changes, shows up in the return temperature moving up or down, so could you have more stable temps? Anyone any thoughts? Link to comment Share on other sites More sharing options...
Bonner Posted February 11 Share Posted February 11 I believe this is how my ASHP (Grant Aerona) regulates flow temperature and it seems to work. Not sure if it makes for faster warm up times but certainly helps with temperature stability. Link to comment Share on other sites More sharing options...
