3KW Electric Water Heater Thermostat for Bathtub, SPA & Hot Tub (Massage Circulation) — Efficient Heating

Compact 3KW thermostat designed for easy mounting in the circulation massage pipe located at the bottom of a bathtub. Controls are straightforward: a mechanical temperature switch lets you set the desired water temperature. Safety features include a water flow switch and an ultra-high temperature protection switch to ensure reliable operation during movement. Internal construction uses 316# stainless steel and an electric heating tube, providing good resistance to chlorine corrosion. The thermostat’s inner tank is engineered for effective circulation, resists slag buildup, and can be disassembled for maintenance.
