The ProTemp 140,000 BTU Kerosene/Diesel Forced Air Torpedo Heater is a powerful option suitable for large spaces such as warehouses, construction sites, and workshops. With a high BTU rating of 140,000, it is capable of heating up to 500 square feet efficiently. The 14-gallon fuel tank ensures prolonged heating sessions without frequent refueling, which is convenient for extensive use. Its matched direct drive motors and blades deliver up to 12,000 cfm of airflow, ensuring effective distribution of heat, while the energy-efficient design minimizes energy consumption, drawing as little as 1.6 amps.
Portability is a plus with this heater, as it is designed to be moved easily despite its 55.9-pound weight. The heavy-duty, maintenance-free motors add to its durability, boasting a two-speed function and thermal protection for safety. The powder-coated steel guards provide resistance to corrosion, enhancing its longevity. However, it comes with a limited one-year warranty, which might be a drawback for those seeking long-term assurances. The heater also requires assembly, which could be a hassle for some users.
This heater is ideal for those needing robust and portable heating in large, open spaces, but may require considerations for assembly. In terms of safety, its thermally protected motors are a reassuring feature.
The Mr. Heater 210,000 BTU Forced Air Kerosene Heater is a powerhouse when it comes to heating large areas, making it ideal for spaces up to 5,250 square feet. This heater features a robust 14-gallon fuel tank, allowing for up to eight hours of continuous operation, which is quite convenient for extended use in garages or during outdoor activities like camping. Its adjustable thermostat and high-output fan ensure that heat is distributed effectively, maintaining a comfortable environment.
Portability is another strong point, with oversized tires facilitating easy movement. The heater's dimensions (approximately 18 by 40-1/5 by 22 inches) make it relatively easy to store when not in use. Safety is also prioritized, with built-in no-flame and over-heat sensors that include an automatic shut-off feature, adding peace of mind while operating.
On the downside, the heater is relatively heavy at 68.6 pounds, which may hinder transport for some users despite its wheels. Additionally, while it operates quietly, being a forced-air heater, it can produce noise, which might be a concern in quieter settings. This model is designed for outdoor use, so it may not be suitable for indoor spaces without proper ventilation.
The Dura Heat DFA50 forced-air kerosene heater offers a solid 50,000 BTU rating, which makes it suitable for heating medium-sized spaces. Its multi-fuel capability, allowing for use with K-1 kerosene, #1 and #2 fuel oil, diesel, JP-8, and Jet-A fuels, adds versatility and convenience. With a one-touch electronic start, it is user-friendly and easy to ignite. The runtime fuel gauges help you keep track of fuel levels, and the fuse-protected electrical system enhances safety.
The high-capacity sealed fan motor and heavy-duty ignitor contribute to its durability and reliable performance. The heater is portable, thanks to the carrying handle, making it easy to move around as needed. However, since it is designed for indoor usage, it might not be the best choice for outdoor settings. Noise could be a factor to consider, as forced-air heaters are generally louder due to the fan operation.
Safety-wise, it includes several features but lacks specifics on features like automatic shut-off or tip-over protection. The Dura Heat DFA50 is a robust and versatile heater with strong heating performance and portability, though it's best suited for indoor use and may produce noticeable noise during operation.
