Outdoor Wood Boiler 350 X Series

The Best-Way Wood Heat outdoor wood boiler represents the culmination of over a year of research and development in the design of an outdoor furnace that meets the Heatmor exceptional standards of convenience, durability & reliability at the same time meeting the strict emission standard established by the US EPA OQHH Voluntary Program. What truly makes the 350 X stand out is the fact that it is designed and manufactured with the same tried and true methods that has made Best-Way & Heatmor a leader in the industry for over 25 years.

Using breakthrough technology, the Heatmor Response & Response Model 350 X uses all the same pieces and parts from our current stoves including a custom designed combustion system. Except we added a high efficiency flue to the 350 X so you get the most heat from your wood. There is no catalytic converter, no hard to run downdraft system, it is simply our custom designed airflow combined with a high efficiency flue to give while offering the customer solid assurance in a tried and tested quality product.

We are so confident that the Heatmor 350 X is the most efficient stove that we made the firebox smaller. You WILL burn less wood. We are also so confident in the quality design and construction of the Response models that we stand behind them with the Heatmor Limited Lifetime Warranty (see below).
