 A
central heating system has a primary
heating appliance such as a
furnace or
boiler located in an out-of-the-way spot such as a
basement or garage. It delivers
heat throughout the house, either by
pumping
warmed air through a
system of air ducts or sending hot
water or steam through pipes to room
radiators or
convectors. With
both
forced-air and gravity systems, one (or more)
thermostats turn
the
heating (or
cooling) plant off and on, operated either manually
or automatically as
room temperatures rise and fall.
Central ducted air systems - In contemporary homes,
ducted
air systems are the most common type of
central heating and cooling.
If your home has an
air conditioner,
heat pump, or
furnace, it is a
ducted air system. There are two main types: forced-air and gravity.
With a
forced-air system, a
furnace warms air, an
air conditioner
cools air, or a
heat pump either warms or
cools air, then a
blower
forces the air through the system.
Cooling and heating/cooling systems -
Air conditioners and
heat pumps are also
forced-air systems. With these,
cooled (and
sometimes
humidified or
electronically cleaned) air is usually
delivered through the same
ductwork and
registers used by
heated
air.
An
air conditioner runs on electricity and removes
heat from air
with basic
refrigeration principles. A
heat pump can provide both
heating and
cooling. In the winter, a
heat pump extracts heat from
outside air and delivers it indoors. On hot summer days, it works in
reverse, extracting
heat from room air and pumping it outdoors to
cool the house.
