Napoleon HMF150 Details
Napoleon Hybrid 150 Wood Furnace Basic Unit

Napoleon’s Hybrid 150 combination furnace is an extremely clean burning wood furnace, with an efficiency rating of 88.6% and EPA emissions of 4.7 grams per hour. The Napoleon® Hybrid 150 is one of the cleanest and most efficient combination solid fuel burning furnace on the market today.

Go away for an extended period without worrying about keeping your wood furnace operational. The Napoleon® Hybrid HMF150 switches from wood to oil or electric automatically. If the furnace runs out of wood, a second thermostat controlling the optional oil and/or electric components will keep your home warm and toasty even if you are not at home, without any interruptions. Even with power failures, the furnace (wood only) is designed to use gravity flow for emergency heating.

Four stainless steel tube combustion system achieves a secondary burn cycle. Not only are you getting energy from the wood, but also from the wood gases which are mixed at the precise ratio of temperature and oxygen. To achieve an extraordinary clean burn without a catalytic combustor, horizontal jets of super heated secondary air are mixed with the fire’s smoke to burn off released smoke particles. You can watch the torch-like secondary flames just below the ceiling during the burn resulting in more heat, cleaner air, fast start up, less chimney maintenance and less trips to the woodpile.

  • Q:

    What type of flue is required for this unit? I am reading other places on the Internet that there are issues when burning wood and oil with one flue, the different exhaust gasses will dissolve concrete, or does this unit produce a cleaner exhaust?

  • Q:

    why dosen't the wood create enough heat to heat the house
    Asked on 1/24/2013 by Anonymous

    1 answer



      According to the product specifications (found here:, the unit creates an average of 82,000 BTUs of heat. The effectiveness of any wood-burning unit in heating an entire home will depend on two important factors: where your home is located in the US and how big the home is. As an example, a home in a Northeast (typically colder winters) will require 50-55 BTUs to heat 1 square foot. So a 2000 square foot home would require at least a 100,000 BTU unit.
