Wood Fired Boilers

Technically, if a heating system heats water it is a boiler. There are both indoor and outdoor wood boilers available on the market. Heat is provided by circulating water from the boiler’s holding tank throughout the home. Radiant heating occurs through the use of baseboards, radiant floor systems, or heat exchangers, which converts the heat stored in the water to the air, which is then forced throughout the house using a system of ducts.

Effective January 29, 2007 EPA (US Environmental Protection Agency) set up voluntary air pollution guidelines for wood-fired boilers, also known as outdoor wood-fired hydronic heaters (OWHH). Now you can look for an orange tag on models from participating manufacturers to see their efficiency and air emission ratings. These models burn cleaner and with fewer fine air particulate emissions than older models.

The EPA Outdoor Wood-fired Hydronic Heaters Program (OWHH) encourages manufacturers to improve air quality by manufacturering and distributing cleaner, more efficient outdoor wood-fired hydronic heaters. This program will achieve emission reductions and protect public health sooner than a federal rule. This is a voluntary program. Currently Alaska has no regulations on OWHH.
