Are thermostats of any use to the housewife on any other device than the incubator?
Thermostats can be set to do work at different temperatures.
Thermostats are fixed to reduce automatically the consumption of gas directly the water reaches a certain temperature.
The boiler-room telegraphs, stoking indicators, rudder indicators, clocks and thermostats were also electrical.
These thermostats are used to regulate dampers on coal and wood furnaces, when they are placed in the rooms to be heated.
Other thermostats are more complicated, as the expanding metal moves a series of levers.
