U31 Gas Fireplace Inserts

A fireplace insert functions as a fireproof box typically made from cast iron or steel. It features a fireproof glass door that creates a closed combustion system, leading to improved heating efficiencies. Fireplace inserts come in wood and gas variations.

Wood-burning fireplace inserts are not only visually appealing but also provide an affordable way to enhance heating efficiency and revive old fireplaces. These inserts preserve the rustic charm of burning wood while maximizing heating output.
