Furnaces: How
Does it Work?
The furnace is the most important component of a central heating
system. It houses all the working parts. So when you replace the
furnace, you replace the vital operating parts of your heating
system. It is by choosing from among the different models and
brands of furnaces available that you determine the quality and
cost of your business’s heating for years to come.
Furnace
The Furnace is part of a forced-air system. Warm air is forced,
or blown, through a system of air ducts to each of the rooms in
the office. Office air drawn into the furnace passes through a
filter, where dust and other small particles are trapped. A
blower unit blows the filtered air through the furnace, and the
air absorbs heat.
Gas Heat
If it is a gas furnace, the heat is supplied by the burning of
natural gas. A mixture of gas and air flows into the burner and
is ignited by the pilot. Combustion occurs, and warm air from
the burner flame rises to fill a chamber known as a heat
exchanger. The heat exchanger becomes hot. Office air passing
around the heat exchanger absorbs that warmth, continues into
the air ducts and the heat is distributed through the
business. The by-products of combustion pass upward through a
venting system and escape through a vent in the roof.
Electric Heat
If the furnace is electric, heat is generated by an electric
heating element. Electric current traveling through the element
creates heat. By the heat transfer processes called conduction
and convection, heat is transferred into the air stream and
flows through the air ducts into the rooms of the business.
The
Thermostat
Whether you heat your office with gas or electricity, a wall
thermostat will be installed. This measures room temperature and
turns the central heating system off or on as the temperature
rises or falls to designated levels. Careful location of the
thermostat is an essential consideration in maintaining maximum
comfort levels in your business.
