Stalgast Boiler Heater for Professional Dishwashers

A boiler heater generates the hot water that professional dishwashers use to clean and sanitise crockery, cutlery and glassware. It sits inside the machine's water tank, where an electric element heats the water to the temperature the wash cycle requires. The element is sealed in a metal tube that transfers the heat directly into the water, raising its temperature quickly and evenly. This method keeps the water at a steady high temperature throughout the cycle, ensuring consistent cleaning results without relying on an external hot-water supply.

The operator does not interact directly with the boiler heater. Once installed inside the dishwasher, it works automatically whenever the machine runs a wash programme. The dishwasher's control system switches the heater on and off as needed, maintaining the set temperature for the duration of the cycle. The heater remains submerged in water during operation, which prevents it from overheating and extends its service life.

This Stalgast boiler heater is constructed as a single unit with a metal sheath that houses the heating element. The sheath is designed to resist corrosion and scale build-up, which are common in hard-water areas. The electrical connections are sealed to protect against moisture and splashes, making the unit safe for use in wet environments.

The 4500 W power rating means the heater draws a significant load from a 230 V single-phase circuit. In a commercial kitchen, this requires a dedicated circuit with adequate capacity to avoid tripping breakers or overheating wiring. The voltage also determines the type of plug and socket the dishwasher uses, so the circuit must match the machine's requirements.

Cleaning the boiler heater is not part of routine dishwasher maintenance. The unit is designed to be replaced rather than serviced, as scale and corrosion eventually reduce its efficiency. When replacing the heater, the dishwasher must be disconnected from the power supply and drained of water to prevent electrical hazards or water spillage.

This boiler heater fits a range of Angelo Po, Giga, Silanos and Emmepi dishwashers, including universal and pull-through models. The brands and model numbers it serves are listed in the dishwasher's technical documentation, ensuring compatibility with the machine's water tank and electrical system.

In the catalogue, this part is placed under dishwasher spares, specifically for boiler heaters and heating elements.
