The Mr. Heater MHVFBF20LPT is a powerful propane heater well-suited for indoor spaces, offering up to 20,000 BTUs of heat. This makes it an excellent choice for larger areas, such as cabins, garages, or sunrooms, as it can effectively warm spaces up to 700 sq. ft. One of its notable features is the thermostat control, allowing users to maintain their desired temperature easily, which adds convenience to its operation.

Safety is a priority with this heater; it includes an oxygen depletion sensor that automatically shuts off the unit if oxygen levels become dangerously low. This is an essential feature, especially for indoor use, providing peace of mind during operation. The ignition system is also user-friendly, utilizing a battery-powered electronic ignition, making startup quick and hassle-free.

In terms of fuel consumption, it operates at a moderate rate of .926 lbs per hour, which is reasonable for the heat output it provides. The blue flame technology employed here utilizes convection heating, effectively distributing warmth throughout the room, much like a fireplace, which enhances the comfort. However, the heater is designed for indoor use only, which limits its versatility if you need heating solutions for outdoor spaces. Additionally, since it is vent-free, proper ventilation is essential to ensure safety and comfort, limiting some users in their installation choices.

The Heatstar 30000 Btu Vent Free Radiant Propane Heater with Thermostat and Blower offers a substantial heat output of 30,000 BTU, making it suitable for larger spaces. The adjustable top-mounted thermostat control is convenient for maintaining desired temperatures without constant manual adjustments. Safety is a priority with a built-in low oxygen sensor, which is a crucial feature for indoor propane heaters.

The portability of this unit is enhanced by the option to wall mount or use the included feet kit for free-standing placement. However, at just 1 pound, it might be prone to tipping if not secured properly when used free-standing. This heater is also practical during power outages since it can operate without electricity, though the blower requires power for optimal performance.

The battery-operated electronic ignition (with one AA battery included) simplifies the lighting process. In terms of fuel consumption, propane heaters generally provide a cost-effective heating solution, although specific consumption rates are not detailed here.

The heater includes both wall mount hardware and base feet, offering versatile placement options to suit different room layouts. Safety is a priority with the ProCom ML100TPA-B, as it comes with an oxygen depletion sensor (ODS) that automatically shuts off the heater if it detects low oxygen levels or carbon monoxide, ensuring user safety. The push-button ignition system simplifies the start-up process, making it user-friendly even for those not tech-savvy.

On the downside, the heater's white color may not blend well with all interior decors, and its modern slim profile might be too plain for some aesthetic tastes. At 16.87 pounds, it is relatively lightweight, but still might require some effort to move around frequently. The ProCom ML100TPA-B offers a blend of efficiency, safety, and convenience, making it a solid choice for those needing a portable propane heater with thermostat control.
