I don't have access to 240V Power, but would like to put my new boiler to electric instead of gas and was looking at these: http://www.amazon.com/Camco-02853-Screw ... KPJ77AXFPS
I was thinking 3 of these would get me 4500W of available power, and at 120 V they only pull 12.5 Amps and I 3 available 20 amp 120V circuits.
Any thoughts on these as opposed to getting 220V circuits installed?
