About this item

Stay warm and comfortable even on the coldest days with the Mr. Heater F299820 MHVFR20LPT Vent-Free Radiant Propane Heater, a high-efficiency indoor heating solution designed to deliver sun-like warmth directly to you and your space. With its advanced infrared technology and user-friendly features, this heater is ideal for cold rooms, additions, sunrooms, cabins, and more.

Key Features:

  • Powerful 18,000–20,000 BTU Output: Capable of heating spaces up to 700 sq. ft., this unit provides consistent and efficient warmth using liquid propane
  • Radiant Infrared Heating: Multiple burner tiles emit radiant heat that warms people and objects directly—just like the sun—rather than simply heating the air
  • Vent-Free Operation: No chimney or venting required, making installation simple and flexible for indoor use (excluding bathrooms, bedrooms, and RVs)
  • Built-In Thermostat: Offers automatic temperature control for a comfortable environment without constant manual adjustments
  • Battery-Powered Electronic Ignition: Quick and reliable startup with the push of a button—battery included for added convenience
  • Safety First: Equipped with a factory-installed Oxygen Depletion Sensor (ODS) that automatically shuts off the heater if oxygen levels drop below safe thresholds
  • Flexible Mounting Options: Can be wall-mounted or used freestanding with included feet and mounting hardware
  • Optional Blower Fan Kit: For enhanced heat circulation, a compatible blower fan (F299201) is available separately

Benefits:

  • Energy Efficient: Consumes only 0.926 lbs of propane per hour, offering up to 21.5 hours of runtime on a standard 20 lb LP cylinder
  • Reliable Performance: Operates without electricity—ideal for power outages or off-grid heating.
