I'm in the process of gathering parts for a new HERMS system. I have a 1500 watt and 2000 watt 120 volt water heater elements. I want to use these in the HLT but am having trouble figuring out which one to use. I would like to use the 2000 watt bc it would heat faster but i think that it pulls 16 amps. Ive only found 15 watt temperature controllers that are reasonably priced. Should I use the 1500 watt with a Johnson A419, which is rated at 15 amps, or is there a reasonable solution to get the 2000 watt element controlled?
