In 1870 the Washburn Langford Doane Expedition visited the spring, noting a geyser nearby (later named Excelsior).

In all systems, a small supplementary heater increases personal security and reduces lifestyle impacts for a small reduction of autonomy.

Heated air can then be distributed directly for applications such as space heating and drying or may be stored for later use.

Air is the heated drying medium however, if the liquid is a flammable solvent such as ethanol or the product is oxygen sensitive then nitrogen is used.

If I buy a hybrid car, install a solar panel at my home, or upgrade to a more efficient water heater, I get a tax credit.

Another, far less common, type of MEMS based accelerometer contains a small heater at the bottom of a very small dome, which heats the air inside the dome to cause it to rise.

When warming up a steam turbine for use, the main steam stop valves (after the boiler) have a bypass line to allow superheated steam to slowly bypass the valve and proceed to heat up the lines in the system along with the steam turbine.
