Title: Electrically Ignited Pilots in Furnaces
Author: James McCosker
Article:
Standing pilot lights are quickly becoming obsolete. A standing
pilot light presents fire and carbon monoxide dangers along with
wasting gas. Electrical furnace starters are now standard on all
high efficiency <a

aintenance.html">Denver heaters</a>. With electric ignition,
your furnace only uses energy when it needs it. This by itself
can increase your SEER rating significantly.
The really modern systems light the burners directly. This is
called hot surface furnace ignition. This means that when the
thermostat calls for heat, a hot igniter above the burners heats
up and then ignites the gas when it is released. Other models
electrically ignite a pilot whenever heat is needed. Not only
furnaces, but any kind of heater using gas flame can benefit
from electronic ignition. Denver HVAC companies install electric
ignition systems in boilers and water heaters as well.
An important part of the ignition system is proving the pilot or
burner flame is lit. The whole system fails if the solid state
controls do not know if the burner is on or not. The fail safe
will shut down the system if the sensors do not sense a flame.
This is because it is dangerous to leave the flame burning
without regulation. It is also to prevent the heater from
spewing un-ignited gas into the building. If you smell gas or
your furnace has shut off unexpectedly, call a <a

immediately.
Often the flame sensor is just fowled with residue and once
cleaned by a HVAC tech it will operate normally. However this
system is still much more reliable than a standing pilot
furnace. These pilot lights blow out and need to be re-lighted
manually. This defeats the purpose of the pilot being lit all
the time.
Along with electronic ignition, two other ways to get the most
out of your heating fuel are to get air handlers with built in
induction blowers, and condensing heat exchangers. The blower
forces air into the combustion chamber, which aids in both
combustion and exhaust of gases. The condenser is an additional
heat exchanger that takes the heat out of the water vapor
byproduct of natural gas combustion. These devices save energy
and also increase the air quality of the home.
Some <a href="http://denverairconditioning.blogspot.com/">HVAC
companies</a> even offer oil fired boilers that use electrical
ignition technology. This technology itself has resulted in
increases of efficiency of around 30% in the last 25 years.
