Electrothermic Head – 230V 2-Wire

R355.74R383.07 Incl VAT

A normally closed/open electrothermic head is, essentially a 2 port zone valve that opens and closes the port to the underfloor loop when energised by the room thermostat. The electrothermic head is fitted to the return manifold bar and are available in 230V or 24V versions, with auxiliary switch also available to provide an electrical interlock if required. At the heart of the electrothermic head is an electrothermic element. The element uses a wax compound that expands when it takes on heat. This expansion drives a small piston in a linear direction. The heat is created when current is passed through a PTC resistor attached to the element body.
