    power requirement for hayward heater

    I have to install a Hayward H series heater(h200fdn) . I can not find any power requirement for this unit. I know it can be set up on either 120 or 240. I would like to know what the amperage draw is. I doubt it is very high, but I would still like to know for peace of mind, Thanks.

    It can be wired either way and the power draw is extremely low so a 15A breaker is sufficient. You can also piggy back the power on the motor power so the heater shuts off when the pump shuts off. Otherwise the exhaust fan will run when the pump shuts off.
