Hot tub wiring 120 vs 240 volts?
I will be wiring up my hot tub in the next day or two and it has the option of being wired into a 120 volt or a 240 volt circuit. I am curious what the benefits are of using the 240 volt configuration.
At first glance it appears that the primary benefit in using the 240 volt circuit will energize a higher wattage coil in the heater allowing it to heat quicker.
I am not all that well versed in electrical theory and am curious if it is advantageous to have a fairly heavy consumer of electricity drawing its current through both legs of the incoming line as opposed to only one? i.e. does the meter measure as accurately with the current running in only one leg of the incoming line as opposed to current flowing through both.
Also has anyone tried an "ozonator" to reduce the need for bromine in the water?
Thanks in advance, Karl
