Check Price on Amazon

The Comfort Glow direct vent model provides 25,000 BTU and lists coverage up to 825 sq. ft. It features a sealed burn system and matchless piezo ignition for safety and consistent combustion.

Key Features:

  • Direct Vent Sealed Combustion isolates combustion air from room air for improved indoor air quality.
  • Safety Pilot And Pressure Regulator to stop gas flow if the pilot light is extinguished.
  • Space-Saving Wall Mount design with compact dimensions for tight spaces.

Application Notes: Direct vent heaters are often preferred where indoor air quality or ventilation is a concern, as combustion products are routed outside. Installation typically requires a through-wall vent or approved vent kit.

Buying Guide: How To Choose A Gas Wall Heater

Selecting the right gas wall heater involves matching heater type, fuel, output, installation needs, and safety features to your space and local codes. Review these core considerations before buying.

1. Heater Type: Infrared vs Blue Flame vs Direct Vent

Infrared (Radiant) heaters warm objects and people directly, useful in open or drafty spaces and for quickly perceived warmth. Blue Flame (Ventless Convection) heaters heat air for even distribution and can be effective in enclosed rooms. Direct Vent (Sealed Combustion) units exhaust combustion gases outdoors and are preferable where indoor air quality or venting options are concerns.

2. Fuel And Conversion

Confirm the heater’s fuel type (Natural Gas or Liquid Propane). Some models are dedicated to a specific fuel and do not permit conversion. Consider availability of gas service and any local restrictions on vent-free appliances.

3. BTU Output And Room Coverage

Match BTU output to room size and heat loss. Higher BTUs suit larger or poorly insulated spaces. Manufacturers often provide estimated square footage; use those as planning guidance, not exact measures. For rooms with high ceilings or cold climates, consider oversizing modestly.

4. Venting And Installation Requirements

Vent-free units avoid external venting but require compliance with room size, ventilation, and code restrictions. Direct vent models need through-wall venting. Determine clearances, mounting options, and whether you require professional installation or a certified technician for gas connections.

5. Safety Features

Look for Oxygen Depletion Sensors (ODS), automatic shut-offs, sealed combustion for direct vent models, pressure regulators, and pilot safety mechanisms. These features reduce risks related to combustion byproducts and low oxygen scenarios.

6. Controls And Operation

Decide between manual controls and thermostatic models. Thermostat-equipped units provide more precise temperature management and energy efficiency. Consider ignition type (piezo, battery-powered electric) and whether the heater operates during power outages.

7. Indoor Air Quality And Ventilation

Ventless heaters introduce combustion byproducts into the room within allowable limits, so ensure adequate ventilation and monitor humidity and CO levels where applicable. Direct vent units keep combustion sealed from indoor air and are often preferred in tight or occupied living spaces.

8. Energy Efficiency And Running Costs

Compare fuel consumption rates and reported BTU efficiency. Blue flame and infrared approaches differ in perceived warmth and circulation; choose the type that aligns with how you use the space to optimize energy use.

9. Local Codes And Manufacturer Recommendations

Research state and local building codes for vent-free and gas appliances. Follow manufacturer specifications for clearances, altitude adjustments, and installation procedures to maintain safety and warranty coverage.

10. Maintenance And Support

Consider ease of cleaning, access to replacement parts, and the availability of service technicians experienced with gas wall heaters. Regular inspections and annual maintenance can improve safety and performance.

Comparison Perspectives: For homes prioritizing indoor air quality and sealed combustion, direct vent units like the Comfort Glow model are often more appropriate. For rapid localized warmth and minimal installation requirements, infrared or ventless options such as the Dyna-Glo or ProCom infrared models can be effective. For robustness during power outages, manual-ignition or piezo-based models like the ProCom MN300HBA-B should be considered.
