Performance Notes: This model emphasizes efficient convection heating and thermostat accuracy. Vent-free design keeps installation simple, but indoor combustion byproducts must be managed per ventilation guidelines.
Dyna-Glo BFSS20NGT-2N 20,000 BTU Thermostatic Heater
The Dyna-Glo BFSS20NGT-2N is a vent-free blue flame heater with a thermostat and adjustable output from 10,000 to 20,000 BTU, suitable for spaces up to 700 square feet.
Key Features: Natural gas ready (no fuel conversion allowed), blue flame convective heating, and a thermostatic control for maintaining set temperatures. The unit’s range makes it adaptable to smaller rooms or bedrooms.
Performance Notes: Lower maximum BTU and adjustable range improve efficiency for medium rooms. Vent-free operation delivers good heat distribution but requires adherence to indoor air quality and clearance requirements.
Comfort Glow 25,000 BTU Direct Vent Wall Heater
The Comfort Glow 25,000 BTU model is a direct vent/vented natural gas wall heater that heats up to 825 square feet. It uses a sealed burn system for increased safety and controlled combustion.
Key Features: Sealed burn system with Matchless Piezo ignition, built-in pressure regulator and safety pilot that stops gas flow if the pilot is extinguished. Space-saving wall-mount design and proven safety controls.
Performance Notes: Direct vent units exhaust combustion products outdoors, improving indoor air quality compared with ventless units. They are a good option for homes where ventilation and code requirements favor vented systems.
Buying Guide
This buying guide focuses on thermostat-equipped natural gas wall heaters, comparing ventless vs vented designs, thermostat types, installation concerns, and safety considerations to help match a heater to your home.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Venting Type: Ventless vs Direct Vent
- Ventless (Vent-Free / Blue Flame / Infrared): No exterior venting required, simpler installation, often higher BTU per unit for room coverage. Requires attention to indoor air quality and adherence to local codes.
- Direct Vent / Vented: Exhausts combustion gases outdoors via sealed system. Better for indoor air quality and often required by local regulations in tighter homes.
Heating Technology
- Blue Flame (Convection): Heats air that circulates around the room; provides even warmth similar to central systems. Good for whole-room heating.
- Infrared (Radiant): Warms people and objects directly; can feel efficient in drafty or high-ceiling spaces. Less effective for heating entire volumes uniformly.
Thermostat Types and Control
- On-Unit Mechanical Thermostats: Simple, reliable, often with High/Medium/Low or adjustable setpoints. Suitable for basic temperature control.
- Digital/Programmable Thermostats: Offer precision and scheduling; can improve comfort and efficiency when available.
- Consider thermostat accuracy and whether it senses air temperature near the unit or in the room’s occupied zone.
BTU Capacity and Room Size
- Match BTU output to room size: higher BTU models heat larger areas faster. Example coverages: 10k–20k for up to ~700 sq. ft., 25k for ~800–1,000 sq. ft., 30k for larger or open floor plans.
- Account for insulation, ceiling height, and climate. Higher ceilings or poorly insulated rooms may require more BTUs.
Installation And Location Considerations
- Wall Mounting: Verify framing and clearances. Many models include hardware, but professional installation ensures code compliance.
- Floor vs Wall Placement: Some units include base feet for floor use—consider airflow and thermostat placement.
- Check local building codes for ventless heater restrictions and required CO/combustion air provisions.
Safety Features
- Sealed Burn Systems and pilot safety regulators prevent gas flow if the pilot goes out—common on vented units like the Comfort Glow.
- Oxygen Depletion Sensors (ODS) and CO detection are important for vent-free units; ensure adequate ventilation and follow manufacturer spacing requirements.
- Look for automatic shutoff, pressure regulators, and reliable ignition systems to minimize risks.
Efficiency And Operating Cost Perspectives
- Ventless units typically deliver nearly all generated heat to the room (high apparent efficiency) but can allow combustion products indoors.
- Direct vent units slightly lose heat through exhaust but preserve indoor air quality. Long-term operating cost depends on gas rates, unit efficiency, and heating schedule.
Maintenance And Longevity
- Regular inspection of burners, pilot, and ventilation paths is essential. Keep clearances and filter (if present) maintenance on schedule.
- Annual professional service verifies gas line integrity, ignition function, and safety controls—especially important for ventless models.
Comparison Checklist
- Determine preferred venting type based on home tightness and local code.
- Match BTU to room size and insulation quality.
- Prioritize safety features like sealed combustion, pressure regulators, and ODS where applicable.
- Choose thermostat type based on desired control precision and convenience.
- Factor installation complexity and whether professional installation is needed.
