To choose a good gas heater, consider factors like energy efficiency, size, safety features, and fuel type to ensure optimal heating for your space.
Selecting the right gas heater can save you money on energy bills while keeping your home comfortable. With so many options available, it’s important to understand key factors like efficiency ratings, sizing, and safety features before making your purchase.
Types Of Gas Heaters
Gas heaters come in several styles, each with unique benefits:
Wall Heaters
Wall-mounted units save floor space and provide focused warmth. Wall heater knob replacements are easy to find if needed.
Built-In Heaters
Permanent installations offer seamless integration with your home’s design. Built-in gas heaters provide consistent warmth without taking up living space.
Portable Units
Freestanding heaters can be moved between rooms as needed. These work well for supplemental heating in specific areas.
Key Selection Factors
Heating Capacity
Measure your space to determine the right BTU output:
| Room Size (sq ft) | Recommended BTUs |
|---|---|
| 100-300 | 5,000-10,000 |
| 300-600 | 10,000-20,000 |
| 600-900 | 20,000-30,000 |
Energy Efficiency
Look for high AFUE (Annual Fuel Utilization Efficiency) ratings:
- 80% AFUE = Standard efficiency
- 90-95% AFUE = High efficiency
- 96%+ AFUE = Ultra high efficiency
According to Energy.gov, upgrading from 80% to 95% AFUE can save $30-50 per year in energy costs.
Safety Features
Essential safety components include:
- Oxygen depletion sensor
- Tip-over switch
- Overheat protection
- Child lock
Fuel Type Considerations
Natural Gas vs Propane
Natural gas is cheaper where available, while propane works in rural areas. Propane burns hotter but costs more per BTU.
Venting Requirements
Direct-vent models are safest for indoor use, pulling combustion air from outside. Vent-free heaters require proper room ventilation.
Installation Tips
Professional vs DIY
Built-in units require professional installation for gas line connections. Portable propane heaters can often be set up by homeowners.
Location Planning
Keep heaters at least 3 feet from furniture, curtains, and other combustibles. Place on stable, level surfaces away from foot traffic.
Maintenance Requirements
Regular maintenance ensures safe operation and extends heater lifespan:
- Clean burner and vents annually
- Check gas connections for leaks
- Replace filters as needed
- Inspect ignition system
For propane heaters, Consumer Reports recommends checking regulator function each season.
Cost Comparison
Gas heater prices vary by type and features:
| Type | Price Range | Operating Cost/Hour |
|---|---|---|
| Portable | $100-300 | $0.30-0.60 |
| Wall-mounted | $400-800 | $0.20-0.40 |
| Built-in | $1,500-3,500 | $0.15-0.30 |
Smart Features
Modern gas heaters offer convenient technology:
- Wi-Fi thermostats for remote control
- Programmable timers
- Energy usage monitoring
- Voice control compatibility
