Ireplaced 3, 1500 amp heaters with 3, 2000 units which run off of a single thermostat 22 volts. 2 units come on together and the 3rd unit later by itself. Do i change the thermostat or reduce 1 heater to 1500 watts? Thanks, Helen
each 1500 watt heater draws 6.25 amps
each 2000 watt heater draws 8.33 amps
three 1500 watt heaters draw just under 20 amps
three 2000 watt heaters draw 24.75 amps which will blow a 20 amp two pole breaker. do you have a separate relay operating off a 24 volt thermostat?
