Pool Heater Repair vs Replacement: Which Should You Choose?

Decision guide to help you decide whether to repair or replace your pool heater.

Repair vs Replacement Decision Guide

When to Repair

Repair makes sense if:

  • ✓ Heater is less than 10 years old
  • ✓ Repair cost is less than 50% of replacement
  • ✓ Issue is isolated (one component failure)
  • ✓ Heater still runs efficiently otherwise
  • ✓ You plan to keep pool for 3+ more years

When to Replace

Replacement makes sense if:

  • ✓ Heater is 15+ years old
  • ✓ Repair cost exceeds 50% of replacement
  • ✓ Multiple components are failing
  • ✓ Heater runs but inefficiently (high gas bills)
  • ✓ You want newer, more efficient technology

  • • Gas valve replacement: $300-$600
  • • Thermocouple: $150-$300
