Furnaces
Natural gas furnaces
provide the warmest heat. Substantial saving can
be achieved by using
2 stage gas
furnaces. When a thermostat calls for heat only
65% of the available heat is turned on. If the
furnace can heat the home in 10 minutes or less
the other 35% never comes on. Imagine how much
energy that could save. Did you know furnaces
are oversized except on the coldest days? The
majority of the time Oklahoma heating days are
moderate and only require lower heating
capacities. Natural gas furnaces are available
in 80% - 90%
afue models.
