A thermal actuator is a type of mechanical device that converts thermal energy into mechanical motion. In the context of radiant heating and cooling systems, such as underfloor heating, thermal actuators are crucial components. They work based on the principle that materials expand and contract with temperature changes. Specifically, a thermal actuator typically contains a wax material or fluid that responds to temperature variations. When the temperature changes, the material expands or contracts, creating a movement that can be used to operate a valve or a mechanical component.
