Thermic Fluid Boiler

Dual-stage wood gasification Boiler

Before we begin singing the virtues of wood furnaces for heating it might pay to read Why your wood heater is a bad idea by by Fay Johnson. If you can’t be bothered, her summary is this: “I still love wood heaters, but owning one meant owning its pollution. Even if we achieved consistently prefect operation, I knew that other heating choices would be better for the environment and the community. We replaced our heater with a less polluting alternative. It’s a bit less evocative but does come on at the flick of a switch.”

Having acknowledged that poorly designed wood furnaces are a source of pollution in towns and cities, the New York Dept of Health provides this information of gasifier type wood furnaces:

“Dual-stage wood gasification boilers are the most efficient firewood burning units available on the market today. They can be installed indoors or in a structure close to the home. They are called dual-stage because the smoke and gasses are burned in a hot secondary chamber with temperatures much hotter than an outdoor wood boiler. This high efficiency design results in much less smoke, however, they also have more exacting fuel wood requirements. They work best with very dry wood and will not operate with poorly seasoned wood. They also work best when operated with an auxiliary heat storage water tank since this allows the entire charge of wood to be burned continuously, further improving efficiency. The stored heat is then used over time depending on demand. When operated during the non-heating months with an auxiliary heat storage water tank, gasification units only require a fire about every four to seven days depending on how much hot water you use.

Heat storage water tanks are insulated water storage tanks used to store heat, allowing a boiler to operate most efficiently by burning the firewood hot and fast. The stored heat can then be used for heating your home as needed. Heat storage water tanks work well with gasification boilers, and can also be used for solar heat storage.”
