Unit Heaters

Last Updated: October 2007
See the federal standards main page to view current status

Unit heaters are used to heat open commercial spaces such as factories, warehouses and garages.  They are typically hung from ceilings.  The federal Energy Policy Act of 2005 contains unit heater standards, federalizing a standard that had previously been adopted by several states.  The standard requires that unit heaters be equipped with an intermittent ignition device and have either power venting or an automatic flue damper.  The standard takes effect in August 2008.

There is no recent ASAP activity regarding unit heaters.
