Application
The QW damper thermostat offers automatic
temperature control and economy in the consumption of
fuel. It can be used on room heaters, boilers, wood fired

room heaters.
Thermal operation is by liquid expansion in the sensing
phial, through copper capillary tubing to a stainless steel
diaphragm capsule located in the instrument head.
The QW is also used to optimise the distribution of core
heat in night storage heaters by regulating the flow of
