The insulated WP heating assembly is designed for direct water heating, particularly used in enamel-coated tanks.

It consists of three U-shaped tubular heating elements and the capillary thermostat cover mounted in a head with a G1 1/2″ thread. The heater features a plastic housing, temperature regulation (30-75°C), an additional temperature limiter (98°C), and a work mode indicator. The insulated design of the heater protects the enamel-coated tank from corrosion.
