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.
- We currently maintain the largest masonry heater
performance database in North America.
- Lopez participated with two EPA
accredited labs in a simultaneous field test series of masonry
fireplaces at McNear Brick in California in 1995.
- In 2004 we opened a test facility at Masonry Stove Builders.
In 2015 this was expanded
and became the MHA Research Laboratory
- OMNI did
comparison onsite testing at Lopez Everett in 2011.
- Two MHA members
visited Brookhaven National Laboratory in 2014 to participate in
particulate sampling comparison testing using the Condar portable
dilution tunnel.
- In
January 2017, we participated with US-EPA in
sponsoring testing at Hearth Lab Solutions LLC in Randolph, Vermont to
help develop a fueling protocol to allow
certification testing of manufactured masonry heaters. This was the
first time that the Condar portable dilution tunnel has run
simultaneously with EPA
Method 5-G on a masonry heater.
A number of papers have been published describing the
research at Lopez Labs. These are available at Lopez
