About the Osburn Matrix 1900

Common Questions
What is a fireplace insert and when do you need one?
Fireplace inserts are sealed metal fireboxes that slide into a pre-existing masonry fireplace, converting a drafty open hearth into a powerful heating system. If you already have a wood-burning fireplace, an insert is one of the quickest ways to upgrade its efficiency, heat output, and safety.

Catalytic or non-catalytic: which wood insert style is right for you?
The most important question is how long the insert keeps your house warm before you reload. Non-catalytic (tube-style) inserts deliver strong heat quickly with typical burns of 4 to 8 hours per load; catalytic models trade some immediacy for longer, steadier burns.

How long does installation take?
Shorter than you’d think. While permits and parts take a few weeks in the background, the actual in-home disruption for most projects is limited to just one day, and inserts often take only half a day when gas and electric are already in place.
