Simple Heater Question

[boise]

Newbie here, I have a wall mounted thermostat that runs heat and cool but this system monitor has a switch that says heater and I was wondering what it is. You can see it on the bottom right next to the Pump switch.

Thanks for your help.

I'm guessing that is the switch for your tank heaters.

That usually is the switch for the Hot Water Heater.

Yeah, having a tankless makes you forget what that thing is. Wish I had a tank heater!
