Although gas furnaces are more efficient than oil furnaces that.
Heating oil furnace efficiency.
Let s take a look at how oil fired furnaces stack up.
They use less fuel than other furnace types but most do not achieve an efficiency greater than 90.
An efficiency starting point.
These are more expensive having starting costs for the furnace itself at around 5 000.
A few high end brands have an efficiency of 95 by using a condenser.
Oil furnaces are typically not very efficient.
While up to 92 afue performance is impressive there are much more energy efficient furnaces from both rheem and other brands mentioned.
This furnace is recognized for its easy installation and maintenance saving you in the short and long term on installation and repair costs.
Upgrading your furnace or boiler from 56 to 90 efficiency in an average cold climate house will save 1 5 tons of carbon dioxide emissions each year if you heat with gas or 2 5 tons if you heat with oil.
For example a 90.
An oil fueled furnace is measured by the unit s annual fuel utilization efficiency afue which is a comparison of the heat output and the total energy used by the furnace.
Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half.
Up to 92 afue.
