Blaze King Princess 32 Wood Stove

The Blaze King Princess 32 wood stove is a high-efficiency catalytic wood stove designed for homeowners who want long burn times, controlled heat and efficient wood combustion. It features a 2.91 cu. ft. steel firebox, a mechanical thermostat that controls heat output without electricity, and a 6-inch flue.

The Princess 32 is rated at up to 82% efficiency, with published emissions of 0.55 g/hour and heat output of up to 36,300 BTU/hour. Blaze King lists a maximum low-setting burn time of up to 32 hours, although actual burn time depends on wood type, moisture content, chimney draft, weather and the home’s heating requirements.

Long Burn Times and Controlled Heat

The Princess 32 combines a large firebox with catalytic combustion and thermostat control. Its thermostat automatically regulates combustion air without requiring electricity, helping maintain a controlled heat output over extended periods.

The advertised 32-hour burn time should be understood as a low-output endurance figure rather than 32 hours of maximum heating. Blaze King publishes a low output of approximately 11,974 BTU/hour and a high output of up to 36,300 BTU/hour.

This makes the Princess 32 particularly useful for homeowners who want to stretch a load of firewood over a long period. During colder weather, when a home requires more heat, the stove may operate at a higher setting and use the same fuel load more quickly.

2.91 Cu. Ft. Firebox

The Blaze King Princess 32 wood stove has a 2.91 cu. ft. steel firebox designed for substantial wood loads. It accepts logs up to 19 inches, with approximately 16-inch logs recommended for regular loading.

Its deep firebox design also helps reduce the chance of hot coals rolling toward and out of the loading door during normal operation.

Firewood quality has a major effect on performance. Blaze King recommends properly seasoned wood with moisture content around 20% or lower. Dense hardwoods can also provide different burn times and heat output compared with lighter wood species.

6-Inch Venting Required

The Blaze King Princess 32 requires 6-inch venting.

The chimney is an important part of the stove’s overall performance. The correct flue diameter alone does not guarantee good operation. Chimney height, elbows, horizontal runs, elevation and draft can all affect combustion and low-output performance.

Blaze King’s installation documentation warns that inadequate draft can contribute to smoke spillage, poor heat output and difficulty maintaining catalytic activity at low settings.

Before installation, confirm that the proposed chimney meets the current Princess 32 installation requirements. The installer should also check that the system can provide suitable draft during both high and low operation.

Princess 32 vs. KING 40

The Princess 32 is often compared with the Blaze King KING 40. The two stoves have different strengths.

The KING 40 has a significantly larger firebox and longer advertised low-output burn time. However, its published maximum heat output is only moderately higher than the Princess 32.

The Princess 32 may therefore be a better fit for buyers who do not need the KING 40’s larger fuel capacity or 8-inch venting system.

Is the Blaze King Princess 32 Worth It?

The Blaze King Princess 32 wood stove is a strong option for homeowners looking for a combination of long burn times, catalytic efficiency and automatic heat control. Its 2.91 cu. ft. firebox provides substantial fuel capacity while its 6-inch flue can be suitable for installations designed around that vent size.

However, the advertised burn time and heating area should not be treated as guarantees. Your home’s heat loss, insulation, firewood, chimney and operating conditions all affect real-world performance.

For buyers choosing between the Princess 32 and KING 40, the key differences are firebox size, burn duration and venting requirements. The Princess 32 uses 6-inch venting, while the KING 40 requires 8-inch venting.
