Sengoku HeatMate Kerosene Heater vs Sengoku HeatMate HMN-110

Both are wick-based kerosene heaters that run without electricity, so the choice comes down to how much space you need to heat. The HeatMate 23500 puts out roughly 23,000 BTU and covers up to about 1,000 square feet, while the HMN-110 is a smaller 10,000 BTU radiant unit rated for around 380 square feet. Owners of the larger unit praise its long burn and strong output for shops and open rooms; the HMN-110 is the easier pick for a single room, a garage, or a power outage where you want a smaller, simpler heater.

• Choose the Sengoku HeatMate 23500 if you need to heat a large open space like a workshop, barn, or big basement and want the higher output and longer run time from a bigger tank.
• Choose the Sengoku HeatMate HMN-110 if you are heating one room or a garage, want a smaller and lighter unit, and value the built-in timer and radiant spot heating.
