More about the Therm 20-08421 Heater Flow Thru 5.5KW 240V 13":
This is a 5.5 KW, 240V heater with a 13" flow-through configuration. 

Sensors are built directly into the heater assembly, no post-installation required. It includes the pressure switch, thermostat, high limit, and contactor already fully integrated into the heater.

Make sure to test all of the included components before daily use of this spa heater, due to the sensitive nature of the materials used in this spa heater.

This heater is a replacement for the matching 20-08421 part number in any spa configurations that use Therm parts. It may also be a direct replacement for similar 13" flow through setups, but please consult the owner's manual or contact the manufacturer before installing this heater in your own spa.
