SBI HE350: is it worth buying?

Wood stove by Stove Builder International. Also sold as FP-15-Waterloo, Horizon, Monaco XL, WFP100, FP-15A Waterloo, St. Clair 4300 and more.

A good pick if you want lots of heat and long burns between loads.

The catch: more wood used for the same heat.

Other questions

What size chimney liner does it need?

Match the liner to the flue collar size in the SBI HE350 owner's manual, and have a certified installer confirm it fits your chimney.

It's non-catalytic. What does that mean?

There's no catalytic combustor, so no combustor part to replace down the road.

What do these numbers mean?

The EPA tests every new stove before it can be sold. "Heat" is the most heat it put out in the test. "Clean burning" is smoke per hour. "Heat from each log" is the share of the wood's energy that reaches your room. Firebox size tells you how much wood it holds, which drives how long it burns.
