To match
the BTUs you have now, 115 volt units, it will cost you twice as much in
electricity.


How do you figure that? Amps drops when voltage doubles, but watts is what
we pay for.


Hi,
Higher voltage unit would have better efficiency but not to a tune of
double amount. Watt is unit of power. Energy is measured in Watt hour.
