Low EPA Emissions Across All Outputs

The Ideal Steel Hybrid achieved weighted average emissions of 0.54 gm/hr using method 5G3, and an “Adjusted Emissions” of 1.04 gm/hr.  The adjustment factor was created in 1988 to account for prospective differences in test methods, and is currently the result published by EPA.  The new EPA regulations propose to eliminate the adjustment factor.  In any case, the Ideal Steel Hybrid will have among the lowest, if not the lowest, emissions among affordably priced stoves.

Further, the Ideal Steel Hybrid has the lowest “high burn” emissions on record.  Normally, the way manufacturers lower the “weighted average” emissions is to limit the high burn rate to under 40,000 BTUs/hr, because emissions generally go up as output goes up.  The Ideal Steel Hybrid emits a record low 1.3 gm/hr at 60,000 BTU/hr, in large part due to the addition of an automatic catalyst air intake (see Under The Hood 4: Catalyst Air:  We apply an old idea in a new setting).

The Ideal Steel Hybrid will meet any new EPA Standard, no matter how stringent, with very high efficiency and very low emissions.

  1. We are looking for a fire that heats after the fire goes out.At least 8 hours to keep 60 sq m warm until morning .Not too expensive as we have built this house ourselves. Seen one idea but ugly and over a 1000 pounds.

  2. Hi Kevin,
    Our double layer soapstone stoves will have more thermal mass to radiate heat out hours after the fire goes out. However, if you are looking for the stove to maintain an adequate home temperature for 8 hours without a fire, that may not be attainable. Most of our customers will burn the stove through the night so they have a nice coal bed to start with in the morning, as well as a comfortable temperature. You can see the wood stoves we manufacture at http://www.woodstove.com/wood-stoves. If you have follow up questions, I can be reached at lorind@woodstove.com or by calling 1-800-866-4344.
