What is SEER Rating?
The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio (SEER) which is defined by the Air Conditioning, Heating and Refrigeration Institute in its standard ARI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.
The SEER rating of a unit is the cooling output in Btu (British thermal unit) during a typical cooling-season divided by the total electric energy input in watt-hours during the same period. The higher the unit’s SEER rating the more energy efficient it is.
For example, consider a 5,000-British-thermal-unit-
The annual total cooling output would be:
5000 BTU/h × 8 h/day × 125 days/year = 5,000,000 BTU/year With a SEER of 10, the annual electrical energy usage would be about:
5,000,000 BTU/year / 10 BTU/W·h = 500,000 W·h/year The average power usage may also be calculated more simply by:
Average power = (BTU/h) / (SEER) = 5000 / 10 = 500 W If your electricity cost is 20¢/kW·h, then your cost per operating hour is:
0.5 kW * 20¢/kW·h = 10¢/h
What is the HSPF Rating?
HSPF (Heating Seasonal Performance Factor) HSPF is the measurement used to gauge the heating efficiency of heat pumps. (A heat pump’s cooling efficiency is measured by its SEER). The higher the HSPF number, the greater the efficiency and cost-savings.HSPF is a seasonal measure (meaning that it takes into account the fact that the heat pumps rarely for as long as is optimal during Spring and Fall). HSPF can be thought of as the “averaged factor” for an entire heating season. HSPF is calculated by taking the total annual heating requirements, including all energy inputs (defrost and back-up heating energy included) divided by the total electric power used. The industry standard rating system compares BTUs of heat output to watts of electrical energy consumed. There are 3.4 BTUs per watt of electricity; an HSPF of 6.8 corresponds roughly with an averaged factor of 2.Today’s models of heat pumps are required to have a minimum 6.8 HSPF. Newer heat pumps manufactured after 2005 are required to have an HSPF of at least 7.7. The most efficient heat pumps have an HSPF of 10.
What is the AFUE Rating
AFUE (Average Fuel Utilization Efficiency) AFUE is the standard measurement of efficiency for gas and oil-fired furnaces. Given in percentages, this number tells you how much of your fuel is used to heat your home and how much fuel is wasted. The higher the AFUE rating, the greater the efficiency. If a furnace has a rating of 80% AFUE rating, the furnace converts 80% of the fuel that you supply to heat – the other 20% is lost out of the chimney. The most efficient furnaces in the industry have AFUE ratings of up to 96.7%.If you have an older furnace (with an AFUE of approximately 60%), you could save up to 40% on your heating bills by replacing it with a new high efficiency furnace! The cost to replace your old, inefficient furnace is paid back through lower utility bills.
GLOSSARY OF TERMS
Annualized Fuel Utilization Efficiency is a measure of your furnace’s heating efficiency. The higher the AFUE percentage, the more efficient the furnace. The minimum percentage established by the DOE for furnaces is 78%.
