Blue Flame vs Infrared — Which Dyna-Glo Wall Heater Is Right for You?
Dyna-Glo offers both blue flame and infrared wall heaters in propane and natural gas from 6,000 to 30,000 BTU. They're both vent-free, both 99.9% efficient, and both work without electricity. The difference is how they deliver heat — and which one is better depends entirely on your space and how you use it.
Side-by-Side Comparison
| Feature | Blue Flame | Infrared |
|---|---|---|
| How It Heats | Warms the air (convection) | Warms objects and people (radiant) |
| Best For | Whole-room, even heating | Quick spot heating, drafty spaces |
| Time to Feel Warm | 15-20 minutes (heats the air first) | Immediate (direct radiant warmth) |
| Room Coverage | Even from floor to ceiling | Strongest near the heater |
| Efficiency | 99.9% (vent-free) | 99.9% (vent-free) |
| BTU Range | 10,000 – 30,000 | 6,000 – 30,000 |
| Fuel Options | Propane or Natural Gas | Propane or Natural Gas |
| Visible Flame | Blue dancing flame (pleasant ambiance) | Glowing ceramic plaque (orange glow) |
| Noise Level | Very quiet | Silent |
| Ideal Rooms | Living rooms, bedrooms, offices | Garages, workshops, bathrooms |
Blue Flame Heaters — Best for Whole-Room Comfort
Blue flame heaters work like a miniature furnace. Gas burns across a series of ceramic logs or burner ports, producing a visible blue flame. The heat rises naturally and circulates throughout the room via convection. It takes 15-20 minutes to bring a room up to temperature, but once warm, the heat is even and consistent from floor to ceiling.
Blue flame is the better choice for well-insulated rooms where you want consistent, comfortable warmth — living rooms, bedrooms, offices, and enclosed spaces. Thermostatic models maintain your set temperature automatically.
Infrared Heaters — Best for Quick, Directional Warmth
Infrared heaters use a ceramic plaque that glows orange-hot when gas flows through it. Instead of heating the air, it emits infrared radiation that warms objects and people in its path — like standing in sunlight. You feel the warmth immediately, even in a cold room.
Infrared is the better choice for drafty or semi-open spaces where heating the air is inefficient — garages, workshops, basements, and large rooms with high ceilings. It's also ideal when you want warmth in a specific area without waiting for the whole room to heat up.
The Bottom Line
Choose blue flame if: You're heating an enclosed, insulated room and want even, consistent warmth. Best for primary living spaces.
Choose infrared if: You want immediate warmth in a specific area, or you're heating a drafty space like a garage or workshop where convection heat escapes quickly.
Both types are vent-free, require no electricity, and operate at 99.9% efficiency. Dyna-Glo offers both in every BTU size from 6,000 to 30,000, in both propane and natural gas.
