Jerry Frisch with his clean burning Frisch Rosin masonry fireplace system (Norbert Senf in the shadows, holding "2 min." sign) (1994)

Lopez Labs was started at the Everett, WA shop of Lopez Quarries/Masonry Heaters. Between 1992 and 1995 we tested a variety of masonry heaters for several weeks every spring at Everett. At over one hundred test runs, this is the largest masonry heater performance database in the United States or Canada. Lopez also participated with two other labs in a simultaneous field test series of masonry fireplaces at McNear Brick in California in 1995.

We have recently opened a second test facility at the Masonry Stove Builders shop here at our home in Greermount, Quebec (close to Ottawa, Canada's capital.) Here we are building a long term performance database on how various operating factors affect specific heater models.

A number of papers have been published describing the research at Lopez Labs. These are available at Lopez Labs Archive
