4 Key Factors To Consider When Buying A Wood Stove

1. BTU Output (Choosing The Right Size)

The BTU/h output is a measure of the heat a wood stove can produce. Wood stove manufacturers typically provide both the maximum BTU heating output and the recommended heating area. For example, the Osborn 2000 wood stove insert has a 75,000 BTU/h output, suitable for heating spaces up to 2,100 sq ft. As a general rule, 60,000 BTU is ideal for a 2,000 sq ft home. However, in colder regions, you might need a higher BTU output. Stoves can be classified as:

• Small: 30,000 BTU to 60,000 BTU.
• Mid-sized: 60,000 BTU to 120,000 BTU.
• Large: 120,000+ BTU.

2. Efficiency (Aim For 70% and Above)

Wood stove efficiency indicates the amount of wood energy converted into heat. For instance, if 14.31 lbs of red oak contains 100,000 BTU, a 50% efficient stove will produce 50,000 BTU of heat, while a 70% efficient stove will produce 70,000 BTU. Although high-efficiency stoves may be pricier upfront, they offer long-term savings by reducing wood consumption. It’s always wise to invest in a high-efficiency model.

3. Emission Rates (Opt For 4.5 g/h Or Lower)

Modern wood stoves have come a long way from the days of “black kitchens” with walls blackened by smoke. Today, EPA-certified models emit less than 4.5 g of smoke per hour, with some even boasting rates below 2.0 g/h. Always choose a stove with an EPA-certified emission rate for a cleaner burn.

4. Burn Time (A Minimum of 5 Hours Is Ideal)

A wood stove’s burn time indicates how often you’ll need to refill it. Longer burn times mean less frequent refilling and the ability to keep the stove burning overnight. Stove engineers achieve this by increasing the wood capacity, enhancing the stove’s performance, or decreasing the BTU/h output. Aim for a stove with a burn time of at least 5 hours for convenience.

Is It Worth the Investment?

Certainly, investing in a high-efficiency wood stove is a wise decision for multiple reasons. Firstly, if you reside in colder regions where wood is a primary heating source, the savings on fuel costs over time can be substantial.
