The Canadian Standards Association (CSA) P.4.1 test method, introduced in 2003, was developed using a consensus based process.   The committee responsible for creating this standard was comprised of industry, utility representatives and regulatory authorities. 

Historically different methods have been used to measure the efficiency of gas fireplaces. These test methods were originally created for wall heaters, space heaters and furnaces. The energy efficiency numbers generated by these test methods did not reflect the actual real life performance of gas fireplaces.

A consistent test was needed to provide an ’apples-to-apples’ comparison when discussing fireplace efficiency. The P.4.1 test was designed to provide a standardized test methodology that as far as possible reflects how fireplaces are typically operated in the real world.

EnerChoice eligibility is based solely on the results of the CSA P.4.1 test method.  This is the only test method for gas fireplaces recognized by the Government of Canada. Because it is the only test method designed specifically for gas fireplaces, there are several States that reference the P.4.1 test efficiency when issuing rebates.



All gas fireplaces sold in Canada are required to be listed with Natural Resources Canada (NRCan).  These listings include details about each model, relevant when choosing the right model for you; including efficiency and ignition type.
