A steam air heater is an apparatus used to heat large industrial or commercial spaces by passing it through a heat exchanger through which steam circulates. It requires a central boiler. Other heater types use electric resistance elements or gas burners to heat the air.
This type of air heater is less common than those using hot water or gas. They are found primarily in buildings equipped with a boiler and a network of steam pipes.
These installations function the same way as do hot water models. A blower forces air through an aluminum heat exchanger containing a coil through which steam circulates. The blower also expels the air so as to ensure mixing, avoiding thermal stratification. A central boiler is required to supply the steam.
A thermal study of the building will indicate the required power and air flow. Other criteria include building use, layout and comfort parameters (output temperature, noise level, air currents produced).
