Corporate History

The company was owned and operated by George Flickas, who brought decades worth of heating experience to the manufacture and design of the GEFCO outdoor wood burning furnace. It appears that the company went out of business sometime around 2007.

Product Lines

GEFCO Hydronics offered three primary models in wood-heating furnaces. The GEFCO 3B heated up to 3,500 square feet. The GEFCO 4B had an advanced heating capacity of 6,500 square feet. The GEFCO 750 had a 15,000-square-foot surface that could easily provide heat for large structures, such as warehouses, and manufacturing plants. All of these models were also energy efficient, with very little or no waste discharge and could be integrated with hot water tanks. All of the furnaces were outdoor models.


GEFCO Hydronics had a 10-year warranty against all leaks and a 1-year warranty on controls, with the provision of reparation or replacement of parts as deemed necessary.

GEFCO Wood Furnace Reviews

Very Unsatisfied

I own a Gefco outdoor furnace. I love this furnace, until it started rusting from the inside of the door through to the outside. George (the owner of Gefco) came and looked at it. He diagnosed that "your trees are causing this door to rust!" From the inside of a solid steel door to the outside, yes George you are an idiot! George welded a 3/16" plate on the outside of the door. As Neil Young says, Rust never sleeps. It came through that plate. I am now in the process of rebuilding the door and seeing what was tack welded where is should have been water tight welding. Great concept, good design, bad service and craftsmanship. Phil Dulong.
