Product details
The Hydroquip 12-0102-K is a 4 kW Incoloy heater element rated for 240 V, supplied with its mounting hardware. It is the replacement element for a spa heater assembly rather than a complete heater.
Why elements fail
The element is the part of a spa heater doing the actual work, and it lives in hot, chemically active water. Scale builds on it, corrosion works at it, and eventually it either opens circuit or shorts to the housing and trips the breaker. The housing, the unions and the sensors around it usually outlast several elements.
Before you order
Match the rating to what came out. This element is 240 V and 4 kW, which is the common residential spa figure, but heater assemblies are also built in other ratings and fitting the wrong one gives you either a heater that never reaches temperature or one that overdraws the circuit.
