Coming Soon: FER

How Will FER Regulations Impact the Heil® Gas Furnace Line?  

What is FER?

Back in 2014, the US Department of Energy established the first national efficiency standards for furnace fans. FER (Fan Energy Rating) specifies a maximum fan energy rating that varies based on the airflow provided by the furnace fan. 

The FER value is different for every furnace model, taking into consideration:

FER is expressed in terms of power consumption (W) per delivered airflow (1000 cfm). The calculation looks like this: 


Each furnace model must be tested to confirm the FER value meets the regulation, and the furnace must be re-designed if the value is above the allowable limit. FER limit targets either a 12% or 46% reduction in watts/cfm, depending on the type of furnace.

The FER regulations take effect on July 3, 2019. 

What does the current Heil blower motor lineup look like?

Variable-Speed Constant Airflow (VCA) ECM

Variable-Speed Constant Torque (VCT) ECM

Fixed-Speed Constant Torque (FCT) ECM

Permanent Split Capacitor (PSC)

How does Heil plan to meet FER standards?

The team at Heil Heating and Cooling has developed solutions to meet FER standards AND continue to support you with a complete gas furnace product offering. 

Heil will eliminate PSC motors in new gas furnaces, focus on new ECM motor technology and add further technological innovations to meet FER standards in a revamped gas furnace line. Heil will continue to support PSC parts for the foreseeable future.

Be sure to check back in early June for full details on a new FER-compliant Heil gas furnace line!
