Abstract

Specifies a method for the determination of the average efficiency and average thermal power output from automatic feed, pellet fuel-burning room heaters, that are intended to burn wood pellets or other suitable solid fuel.

Scope

This Standard sets out a method for the determination of the average efficiency and average thermal power output from a domestic automatic continuous feed, pellet fuel-burning appliance.
