    Osburn has reviewed their procedures and construction to make the already-reliable Matrix wood fireplace insert even better. This carbon steel insert features high efficiency and very little particulate emissions, making it an excellent choice for environmentally conscious people. This massive fire feature fills your home with warmth with the help of its variable-speed blower, but even in the event of a power outage, it generates enormous heat. Osburn has bettered the Matrix wood-burning fireplace insert by modifying the cast iron door to improve its functionality, truly making this updated version a cut above the rest.

    Do you sell the Osburn 3500 insert? Also, what's the most important spec to consider to achieve the best bang for the buck? BTU rating? Firebox size?

    1 Answer
    Yes, we also sell the Osburn 3500 insert. The most important data to look at when shopping inserts is the listed heated area. For example, the Osburn 3500 insert is listed to heat up to 2,700 square feet. The actual heating capability will depend on the location of the appliance, insulation of the home, etc.

    I would recommend this item to a friend.
    Excellent insert
    We purchased the Matrix insert for the modern look, large viewing glass, and the flush mounting fit of it.

    The build quality seems to be excellent and the fit and finish of the door and all the trim pieces is good.

    I've lit a couple dozen fires in it so far and only have one complaint involving the blower assembly. Every now and then some part of the assembly will start a loud vibration, so something must be loose. I haven't yet investigated the issue further.

    The insert puts out plenty of heat. I live in a poorly insulated house with temps currently in the 20s overnight. The temperature will stay nice and comfortable inside.
    Solid build quality Good fit and finish Modern look Flush mount (if your fireplace is deep enough) Blower motor assembly has a loud intermittent vibration.
