Power Usage of Zone Relays and Relay Switches
Hi, I posted this in the Radiant Forum, but didn't get a response on this part, this is probably a better forum for it.
Does anyone know what the power usage of a Taco one zone switched relay is? Probably similar to a single zone control. A Taco guy is telling me it draws 20W when powering stuff, but only enough for the LED (less than 10 ma) when there is no call for heat. I assume this is untrue since the transformer draws a significant amount of power at all times (and is pretty darn warm to the touch). I would guess this draws close to 20W at all times - 24x7x365. Does anyone know? Or do I have to run it through a meter to find out?
As pumps are getting more efficient, what are you guys doing for zone controls and switching relays to conserve power on that end? If my guess is correct, this single relay will draw $300 worth of power in its 15 years of life.
