Buying Guide for Open Flame Heaters
Heat Source and Fuel Type
Open flame heaters may use natural gas, propane, wood pellets, or electricity simulating flames. Propane and natural gas models provide direct radiant heat but require safe ventilation or oxygen sensors. Electric units simulate flames without combustion, offering less safety concern and easy installation. Wood pellet heaters provide authentic outdoor warmth but are less suited for indoor use.
Safety Features
Look for Oxygen Depletion Sensors (ODS) in gas heaters to automatically shut off when oxygen is low. Automatic shutoff on overheating is essential. Electric fireplaces remain cool to the touch, making them safe for children and pets. Always review installation requirements, especially for vent-free gas heaters to avoid carbon monoxide risks.
Heating Capacity and Room Size
Calculate the square footage of the area to heat and compare it with the heater’s BTU or watt rating. Smaller models are best for supplemental warmth or small rooms, while higher BTU units serve larger spaces. Portability can also be a factor if moving the heater between rooms or outdoor locations.
Flame and Ambiance Features
Some electric and wood pellet heaters offer realistic flames with adjustable brightness and flicker settings for decorative effect. Others produce actual flames, which require caution but provide authentic warmth and atmosphere.
Installation and Portability
Consider whether the heater requires permanent installation, wall mounting, or is freestanding. Portable heaters with wheels or handles provide flexibility. Outdoor models must be weather resistant and suitable for open-air use.
Energy Efficiency and Operating Costs
Infrared electric heaters offer efficient supplemental heating without warming the entire house. Gas heaters burn fuel directly for faster heat but require fuel supply and careful monitoring. Look for models that allow thermostatic control to reduce wasteful heating.
