Immersion heaters are best used with portable and other small baptistries. Our 120v version  plugs into a standard 110v outlet and should only be used with portable baptistries as it is slow to heat.

Our 240v immersion heater plugs into a 220v outlet (like a clothes dryer outlet). We recommend the 240v model for walk-in baptistries under 800 gallon capacity and where a built in heater is not practicle or possible.
