The WP heating assembly is used for direct water heating and is applied in acid-resistant and 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 has a plastic housing, temperature regulation (30-75°C), an additional temperature limiter (98°C), and a work mode indicator. Both the heaters and the head are made entirely of acid-resistant steel.
