Upfront Cost Comparison
Standard 50-gallon gas tank. $1,350 to $1,800 installed. Includes removal of old unit, new unit delivery, installation, venting, all connections. See water heater services.
Gas tankless unit. $2,800 to $4,500 installed. Higher unit cost. More complex installation. Venting requirements stricter. Gas line often needs upgrading. Electrical connection for controls. That $1,500 to $2,700 price gap is real. See tankless installation.
Operating Cost Comparison
Tank water heater operating cost. Maintains 40-50 gallons of hot water 24/7 even when you are not using it. Standby heat loss. Gas tank runs $30 to $50 monthly in NWA. Electric tank $45 to $75 monthly.
Tankless operating cost. Heats water only when you turn on the tap. No standby loss. Gas tankless runs $22 to $35 monthly. Electric tankless $35 to $55 monthly. Savings of $8 to $20 per month over tank units. $96 to $240 per year.
Lifespan Comparison
Tank water heaters last 8 to 12 years in NWA. Hard water shortens this. Lack of maintenance shortens this. See water heater maintenance.
Tankless water heaters last 15 to 20 years with proper maintenance. Longer lifespan means fewer replacements over 30 years of homeownership. Tank needs replacement 2-3 times. Tankless once or twice.
Break-Even Math
Tankless costs $2,000 more upfront. Saves $150 per year on operating costs. Break-even at 13 years. But tankless lasts 15-20 years. You come out ahead after year 13. This math assumes gas units, maintained properly, and stable utility rates.
Performance Differences
Tankless advantages. Endless hot water. Multiple showers back-to-back no problem. Never run out mid-shower. Smaller footprint saves space.
Tank advantages. Simpler technology. Easier to repair. Parts more available. Can supply hot water during power outage if gas pilot stays lit.
Which One Makes Sense
Tankless makes sense if you are staying in the home 10+ years. If you want endless hot water. If upfront cost does not strain budget. Tank makes sense if upfront budget is tight. If you are selling soon and will not recoup the tankless premium. If your hot water use is modest and tank capacity is fine.
