You first need to identify what your needs are. If you are looking for ambiance, a temporary heat source in a cottage or a camp,  or a simple a back-up heat source in case of power failure, you do not necessarily need to invest more money in order to buy an EPA certified wood heater. However, if your goal is to heat on a regular basis, the extra dollars will prove to be a good investment. Furthermore, it must be noted that EPA certified heaters release a significantly lower amount of particulates into the atmosphere, which makes wood a renewable and clean source of heat.  As a result, if the style and size of heater you are looking for is available in an EPA-certified version,  it is highly recommended that you invest in this advanced combustion technology. You will help the environment and save on wood consumption.

NOTE: If you live in the United Sates, British Columbia, Nova Scotia, or Newfoundland, EPA certified wood heaters are mandatory. Certain municipalities may also have by-laws that require the installation of EPA-certified wood heaters.
