SpaNET SV Heater Assembly

Complete assembly: optical sensor, heater element, temperature sensors, wiring loom
V2 heaters only are currently available — V1 heaters are discontinued and will require an upgraded control box. Important: V2 heaters cannot be used in V1 SpaNET Control Boxes
Compatible with SV2, SV3, SV4 V2 control systems (see model table below)
Standalone heater elements are not sold separately

Important: Heaters may no longer include unions (images may show unions for reference only)

Which version do I need? (V1 vs V2)

Find the serial number on the front of your controller
If the serial number ends with “V2” → order the V2 heater
If the serial number has no “V” number → it is a V1 controller.
Note: V1 heaters are discontinued. If you have a V1 5–6 kW heater, you must upgrade to a new control box (SV2, SV3, or SV4)

Visual check: You can also tell by looking at the heater itself. If it has two Triacs (small components covered by white silicone) it is a V2. If it has one Triac covered by white silicone, it is a V1.
