The costs of installing a gas heater typically range from $1,500 to $4,000, including equipment, labor, and necessary permits.
Installing a gas heater provides efficient warmth but comes with various costs. Prices range from $1,500 to $6,000 depending on unit type, labor, and additional requirements. This guide breaks down all expenses so you can budget properly.
Average Gas Heater Installation Costs
The total cost to install a gas heater includes the unit price and professional installation fees. Here’s what to expect:
| Heater Type | Unit Cost | Installation Cost | Total Cost |
|---|---|---|---|
| Ventless Wall Heater | $400-$800 | $800-$1,500 | $1,200-$2,300 |
| Vented Wall Heater | $600-$1,200 | $1,000-$2,000 | $1,600-$3,200 |
| Console Heater | $800-$1,500 | $1,200-$2,500 | $2,000-$4,000 |
| High-Capacity Unit | $1,500-$3,000 | $1,500-$3,000 | $3,000-$6,000 |
What Impacts Installation Costs?
Several factors affect your final price:
- Gas line requirements: New gas lines cost $12-$25 per linear foot
- Venting needs: Vent pipes add $300-$1,000 to the project
- Electrical work: New circuits or wiring costs $150-$500
- Wall modifications: Cutting through walls adds $200-$800
- Permits: Local building permits cost $50-$300
Gas Heater Types and Costs
Ventless Gas Heaters
Ventless models (30,000 BTU) cost $400-$800. They’re 99% efficient but require proper room ventilation. Installation is simpler since no venting is needed. Built-in gas heaters often use this design for compact spaces.
Vented Gas Heaters
Vented units (20,000-40,000 BTU) range from $600-$1,200. They require exhaust venting but are safer for bedrooms. Professional installation is crucial for proper venting.
High-Capacity Heaters
Large units (50,000+ BTU) cost $1,500-$3,000. These whole-house systems require significant installation work including:
- Gas line extensions ($500-$2,000)
- Complex venting systems ($800-$1,500)
- Electrical upgrades ($300-$1,000)
Installation Process and Labor Costs
Professional installation typically takes 4-8 hours. Labor rates are $75-$150 per hour. The process includes:
- Gas line connection ($200-$800)
- Vent installation ($300-$1,000)
- Electrical wiring ($150-$500)
- Mounting and testing ($100-$300)
According to Homewyse, basic gas wall heater installation starts at $1,695-$2,032 including labor and materials.
Additional Costs to Consider
Removal of Old Units
Removing an existing heater costs $150-$400. This includes:
- Disconnecting gas/electric ($50-$150)
- Removing venting ($100-$200)
- Disposal fees ($50-$100)
Annual Maintenance
Plan for $100-$300 yearly maintenance:
- Professional inspection ($80-$150)
- Vent cleaning ($50-$100)
- Parts replacement (varies)
Gas vs Electric Heater Costs
Gas heaters cost more upfront but save on energy bills. Electric alternatives have lower installation costs but higher operating expenses.
| Factor | Gas Heater | Electric Heater |
|---|---|---|
| Installation Cost | $1,500-$6,000 | $500-$2,000 |
| Annual Operating Cost | $300-$600 | $500-$1,000 |
| Lifespan | 15-20 years | 10-15 years |
According to HomeGuide, gas wall heaters typically cost 20-30% more to install than electric models but provide better heating performance.
Permits and Regulations
Most areas require permits for gas heater installation ($50-$300). Common requirements:
- Professional installation by licensed technician
- Proper venting for combustion gases
- Carbon monoxide detectors in sleeping areas
- Minimum clearance from combustible materials
Always check local building codes before installation. Improper installation can void warranties and create safety hazards.
