      Q:Do I need a separate thermostat for each one of my three hydronic zones?

      Answer This Question

      A:  Yes you do. A thermostat senses the temperature in a zone and controls the heat being supplied to that zone. You would not want a thermostat to control the heat being supplied to a zone if the thermostat is not in that zone.
