Forced Air System
Why Forced Air Heating Isn't
Smart?Danger tops the list. Any system that relies on combusting gas indoors
is potentially dangerous. This, of course, includes forced air furnaces. Carbon monoxide fumes from such a system kills approximately 400
people every year in North America alone.
Studies in California in 1991 show that there were 252 carbon monoxide
deaths by fuel and combustion appliances. The situation is so serious,
the government recommends that every room be equipped with a Carbon
Monoxide Detector to prevent accidental death. (Source: Tempstat

The Inefficiency Of Forced Air Heating
To understand the ins and outs of how heat is transferred to the
living areas of a house, Duct Transfer Losses must be factored in.
Heat from the furnace is transferred to the air, which is blown through
the ductwork, finally reaching the rooms where the heat is needed. Measure the heat efficiency in these rooms and you'll find that even
the most efficient furnaces don't meet their own test specifications.
Just like baseboards, forced air systems create a bellows effect,
which creates uneven heating. Temperatures are much warmer near the
heat register than in the rest of the room, resulting in serious
heat loss. Also, blowing warm air throughout a house causes drafts,
which also creates low humidity levels. To compensate, you would
have to add the expense of a humidifier to the cost of the forced
air heating system.
No Pings, No Pangs
Another thing to factor in when considering a forced air system
is maintenance. Furnace motors and igniters often malfunction. Fan
belts need replacing and gas valves and burners need periodic cleaning.
Dust, insects, and rodents can get into the ductwork, adding to the
frequency of duct cleaning. In addition, the air filter must be changed
several times a year. Remember, an Allied Radiant Heating System
comes with no motors, belts, fans, filters, valves, etc. And no worries
about rodents, insects, or dust.
