Hot Springs Solana Spaquip Spa Power 600 / 601 Heater Element / Tube Assy - 1.5kw - Replacement Replumb Kit

The original heater tube fitted to Hot Spring Solana Spa Power 600 series controllers, had flanged ends rather than male threaded. (see 2nd image)

The original 1.5kw flanged tube / heater element assembly is discontinued.

Replaced by this generic version with male threads on the ends of the tube, coupled with 2 supplied threaded union assemblies, that will require replumbing to suit.
We do have system replacement options if replumbing is not possible
 
 It comes with the inline temerature sensor which is not actually used in Hot Spring Spas which use an 'in-pool' sensor instead.
