1. Determine the Correct Heater Size

Proper sizing ensures optimal performance and energy efficiency. Consider these factors:

Room Dimensions

Measure your space carefully. As a general rule:

  • Small rooms (100-200 sq ft): 5,000-10,000 BTU
  • Medium rooms (200-400 sq ft): 10,000-20,000 BTU
  • Large rooms (400-600 sq ft): 20,000-30,000 BTU

Climate Considerations

Colder climates may require up to 30% more heating capacity. The U.S. Department of Energy provides regional heating guidelines.

2. Evaluate Energy Efficiency

Look for these efficiency indicators:

Feature Benefit
AFUE Rating Higher than 90% indicates excellent efficiency
Modulating Burner Adjusts heat output for consistent temperatures
Sealed Combustion Prevents heat loss through venting

3. Prioritize Safety Features

Essential Safety Components

  • Oxygen depletion sensor (ODS)
  • Automatic shut-off valve
  • Cool-to-touch exterior
  • Tip-over protection

Proper Ventilation

Natural gas heaters require adequate venting. Options include:

  1. Direct vent (sealed combustion)
  2. Power vent (uses fan assistance)
  3. Vent-free (for specific applications only)

4. Consider Installation Requirements

Professional installation is crucial for gas appliances. Key considerations:

Gas Line Specifications

Most residential gas lines operate at 0.5 psi (pressure). Verify your home’s capacity with a licensed technician.

Wall Structure

Heaters typically require:

  • Minimum clearance from combustibles (usually 12-36 inches)
  • Proper wall stud placement for mounting
  • Access to gas shut-off valve

5. Compare Fuel Options

While focusing on natural gas, it’s worth understanding alternatives:

Fuel Type Pros Cons
Natural Gas Low operating cost, clean burning Requires gas line
Propane Portable, efficient Higher fuel cost
Electric Easy installation Higher operating cost

6. Understand Maintenance Needs

Regular maintenance ensures longevity and safety:

Annual Maintenance Checklist

  1. Clean burner assembly
  2. Inspect venting system
  3. Check gas connections for leaks
  4. Test safety controls
  5. Clean air intake filter

The ENERGY STAR program recommends professional servicing every 2 years.

7. Compare Top Brands and Models

Leading manufacturers offer different features:

Premium Options

  • Rinnai: Advanced modulating technology
  • Mr. Heater: Reliable budget-friendly models
  • Empire: Durable commercial-grade units

Budget Considerations

Entry-level models start around $300, while high-efficiency units can exceed $1,500. Factor in long-term energy savings when budgeting.
