Current Efficiency Standards

For the purposes of this standard a unit heater is defined by 10 CFR 431.242. Unit heaters manufactured on or after August 8, 2008, and distributed in commerce, must meet the energy conservation standards specified in the Code of Federal Regulations, 10 CFR 431.246, which states that it shall (a) be equipped with an intermittent ignition device; and (b) have power venting or an automatic flue damper. To ensure the implementation of the current standards for covered appliances and equipment, DOE has published certification, compliance, and enforcement regulations for these products and equipment in the Code of Federal Regulations (CFR) at 10 CFR part 429
