We are building an off grid passive solar home in northern Ontario Canada. What electrical draw does your system require to work properly. We want a system that will supply our domestic hot water and also supplement our radiant floor heating.
Thanks for your input.

RE: solar water heater
Our control system requires 110 VAC and depending on pump speed draws 30-80 watts.
If you want to use the electric element in the tank then that is 4500 Watts 240 VAC.
