I am a long time HERMS user and I am contemplating a transition to RIMS. What I would like to know is anyone using 240 vac to power their RIMS element? I get the impression that most are using 240 vac elements powered at 120 vac to benefit from the lower watt-density. However, if I were to move to RIMS, it would be plug and play with my existing control panel if I power my element with 240 vac.
