Lopez Labs Co-Operative

Lopez Labs was started at the Everett, Washington shop of Lopez Quarries/Masonry Heaters. Between 1992 and 1995 we tested a variety of masonry heaters for several weeks every spring. We currently maintain 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.
In 2004 we opened a second test facility at the Masonry Stove Builders shop here in Greermount, Quebec (90 minutes from Ottawa, Canada's capital.) We are building a long term performance database on how various operating factors affect specific heater models.
Alex Chernov opened a test facility at Stovemaster in 2009.
Homestead Heat, Solid Rock Masonry and Alaska Hearth Technologies are in the process of setting up test facilities.
One goal of the co-operative venture is to establish common testing procedures and quality control protocols to allow comparison of data.
A number of papers have been published describing the research at Lopez Labs. These are available at Lopez Labs Archive
