Who It’s For

An open masonry fireplace sends most of its heat up the chimney. You want it to heat the house instead, at a sensible price. The Timberwolf Economizer EPI22 is for that fireplace. Leave the opening as it is and it keeps costing you heat every winter.

What Makes It Special

The EPI22 transforms your masonry fireplace into an efficient, clean-burning, and cost-effective heating source. Its large firebox takes logs up to 16 inches and allows a long eight-hour burn.

A dual blower system, a painted black cast iron door, and a large ceramic glass viewing area come standard, and it is certified to the 2020 federal wood heater emission standards. The included five-piece painted black flashing adjusts in depth for installation versatility.

Possible Downsides

• It is a wood fire. You load it, tend it, and carry out the ash.
• It needs a minimum fireplace opening. Your dealer confirms the fit.

If you want real wood heat from your masonry fireplace, the Timberwolf Economizer EPI22 is the right decision. The fireplace becomes the warmest spot in the house again.

The blowers, door, and flashing all come with the insert.
