More About Honeywell
Honeywell can trace its roots back to 1885, but became the company we know in 1904 when a young engineer named Mark Honeywell perfected the heat generator as part of his plumbing and heating business. Since then, Honeywell has become a global leader in plumbing and heating supplies and sells some of the most popular and recognizable thermostats, aquastats, and controls available.
