Gas wall heaters are efficient for localized heating, while central heating systems provide consistent warmth throughout larger spaces, making them suitable for different needs.
Choosing between gas wall heaters and central heating systems depends on your home size, budget, and heating needs. Both options have distinct advantages that make them suitable for different situations.
How Gas Wall Heaters Work
Gas wall heaters are compact units installed directly into walls. They operate similarly to central furnaces but on a smaller scale. These heaters use natural gas or propane to generate heat through combustion.
Key Features of Wall Heaters
- Direct wall installation (no ductwork required)
- Typically heat 100-300 square feet per unit
- Operate on natural gas or propane
- Provide radiant heat that continues after shutoff

Central Heating System Basics
Central heating systems use a main furnace connected to ductwork that distributes heat throughout the entire home. These systems offer whole-house comfort from a single unit.
Central Heating Components
| Component | Function |
|---|---|
| Furnace | Generates heat through gas combustion |
| Ductwork | Distributes heated air throughout home |
| Thermostat | Controls system operation |
Comparing Performance Factors
Heating Capacity
Wall heaters typically provide 5,000-30,000 BTUs, enough for single rooms. Central systems range from 40,000-150,000+ BTUs for whole-home heating.
Energy Efficiency
Wall heaters can be more efficient for small spaces since they don’t lose heat through ducts. However, modern central systems like built-in gas heaters achieve up to 98% efficiency.
Installation Costs
Wall heaters cost $500-$1,500 per unit installed. Central systems range $3,000-$12,000+ depending on home size and existing ductwork.
Safety Considerations
Both systems require proper maintenance and safety precautions:
- Wall heaters need 3+ feet clearance from combustibles
- Carbon monoxide detectors are essential for gas systems
- Annual professional inspections recommended
According to Mt. Hood Ductless, wall furnaces remain popular in small spaces but require careful safety considerations.
Best Applications For Each System
When to Choose Wall Heaters
- Small apartments or studios
- Supplemental heating for cold rooms
- Homes without existing ductwork
- Budget-conscious heating solutions
When Central Heating Excels
- Homes over 1,000 square feet
- Whole-house comfort needs
- Homes with existing ductwork
- Combined heating/cooling systems

Maintenance Requirements
Both systems need regular maintenance:
Wall Heater Maintenance
- Clean exterior surfaces monthly
- Check pilot light operation
- Inspect venting annually
Central System Maintenance
- Change filters every 1-3 months
- Annual professional tune-up
- Duct inspection every 2-3 years
As noted by LA Heating & Air Conditioning, proper maintenance extends system life and improves efficiency for both options.
Long-Term Cost Considerations
While wall heaters have lower upfront costs, central systems often provide better value for larger homes:
| Cost Factor | Wall Heaters | Central Heating |
|---|---|---|
| Initial Cost | $500-$1,500/unit | $3,000-$12,000+ |
| Operating Cost | Lower for small spaces | More efficient for whole homes |
| Lifespan | 10-15 years | 15-20 years |
