Purchasing a High Efficiency Heating System
Learn how to choose a high efficiency heating system that’s right for you.
All natural gas heating systems have what's called an Annual Fuel Utilization Efficiency (AFUE) rating. The rating is expressed in percentages.
Minimum Efficiency Standards
Furnace 78% AFUE
Gas-fired Boilers 80% AFUE
Gas-fired Steam 75% AFUE
The higher the AFUE rating – the more efficient the heating system – and the less energy needed to heat your home.
For example, a new, high-efficiency furnace with a 94% efficiency rating provides 94 cents worth of heat from every energy dollar. By comparison, an older, standard efficiency furnace with an efficiency rating of 60%, provides 60 cents worth of energy for every dollar spent.
Annual Savings: Simple Payback
If you install a residential warm air furnace at 90% AFUE vs. 80% AFUE, the estimated annual savings in energy costs is $115 with a simple payback of approximately 3 years*.
High-Efficiency Furnaces
Furnaces with efficiencies over 90% are called condensing furnaces and offer the most energy savings.
These furnaces achieve 90% AFUE rating by sending flue gases through a secondary heat exchanger. This device further extracts heat that is usable energy for your home.
Remaining flue gases then exhaust outdoors through the vent pipe inserted through the wall or roof of the home. This "direct-vent" piping configuration also draws in outside air for combustion. Since indoor air is not used in the combustion process, cold air leakage (infiltration) is reduced – an added energy savings.
Guarantees and Warranties
A new heating system is a major investment, so make sure you understand the warranties that come with your new equipment.
Parts and labor are usually covered by the manufacturer and installing contractor for the first year. Some brands also offer warranties of two to ten years. High-efficiency furnaces are generally the manufacturer's top-of-the-line products and have longer warranties.
