A wax motor is a linear actuator device that converts thermal energy into mechanical energy by exploiting the phase-change behaviour of waxes. [1] During melting, wax typically expands in volume by 5–20% ( Freund et al. 1982 ).
The replacement of a manual heating control with a conventional wax motor TRV has been estimated to save at least 280 kilograms (620 lb) of CO 2 per year (in 2011 for a British semi-detached house with 3 bedrooms and gas heating [1]). They are also considerably cost-efficient, using heat only when needed, and can reduce heating bills by up to ...
The wax thermostatic element was invented in 1934 by Sergius Vernet (1899–1968). [1] Its principal application is in automotive thermostats used in the engine cooling system. The first applications in the plumbing and heating industries were in Sweden (1970) and in Switzerland (1971).

A Regular Production Option (RPO) is a 3-digit standardized code used by General Motors to designate vehicle options & modifications. RPO codes designate how a vehicle is built, and they've been used on dealership order forms and in assembly plants since at least the 1950s (see Corvette C1).
Zone valves can also be constructed using wax motors and a spring-return mechanism. In this case, the valve is normally closed by the force of the spring but can be opened by the force of the wax motor. Removal of electrical power re-closes the valve. This style of zone valve operates with a perfectly ordinary SPST thermostat.
