This 2 inch diameter flow through hot tub heater is 15" long. 

This type of 4 kilowatt heater is used by many hot tub manufacturers that use either a plastic or metal Balboa spa pack.

For use in both plastic & metal Balboa spa packs, unlike older systems that use pressure switches, this heater has 2 built-in sensors which come with the heater.

Those sensors take the duties of hi limit and temperature sensing so no external pressure switch is needed with this type of control system.

This model 58104 Balboa heater includes the internal sensors.

INCLUDES: complete spa heater with two sensors, two heater split nuts mounted to heater, two tailpieces and 2 heater gaskets.
