Heating Oil Furnace Efficiency

Any conversation about furnace efficiency usually starts with the concept of afue or annual fuel utilization efficiency.

Heating oil furnace efficiency.

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 efficiency starting point.

Most new oil furnaces have afue ratings between 80 and 90 while their gas counterparts boast ratings between 89 and 98. A few high end brands have an efficiency of 95 by using a condenser. Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half. These are more expensive having starting costs for the furnace itself at around 5 000.

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. There s no doubt that how much heating bang for the buck you get is one of the most important considerations in choosing a furnace. Up to 92 afue.

They use less fuel than other furnace types but most do not achieve an efficiency greater than 90.
