Hetta

The Hetta HSEANC02 230V 2-wire underfloor heating actuator is designed to control the flow of heating water through individual zones in compatible underfloor heating (UFH) manifold systems. Featuring normally closed (NC) operation, the actuator keeps the associated valve closed when the power supply is switched off, helping provide reliable zone control in residential and commercial heating installations.

Operating on a 230V AC supply, this electric actuator uses a thermal actuation mechanism to open the valve when energised. Its M30 × 1.5mm connection thread and 3mm stroke make it suitable for compatible manifold valves requiring these specifications.

The Hetta HSEANC02 features a compact design, a 1-metre cable and an IP54 rating as marked on the actuator itself. The spring-return mechanism ensures the valve closes when power is removed.

Whether you're installing a new underfloor heating system or replacing an existing actuator, check the thread size, voltage, valve compatibility and electrical connections before ordering.

heating system components, including wall-mounted boilers, circulating water pumps and electric heating actuators. It features relay switching and a weekly programming cycle for scheduled heating control.

With a 200–240V AC supply and specified load ratings for water and electric heating applications, the HWC018 is intended for installation as part of a compatible heating control system.

The Hetta HM01PT Digital Programmable Thermostat features a large, crystal-clear LCD display for intuitive operation. With built-in programmable settings, it allows precise daily control of your heating system for comfort and energy efficiency.
