The right decision depends on heat exchanger condition, equipment age, parts availability, installation quality, and the total cost of restoring safe operation.
Technical guidance
Repair is often reasonable when the heat exchanger is sound, the heater is installed correctly, parts remain available, and the failure is limited to a serviceable component.
Replacement deserves consideration when the heat exchanger leaks, major assemblies are obsolete, repeated failures continue, or the existing installation needs extensive correction.
A failed igniter or control does not automatically mean the heater is finished. The burner system, gas supply, water flow, venting, wiring, and exchanger condition should be checked first.
A replacement estimate should address gas sizing, electrical disconnect, bonding, plumbing connections, clearances, venting, pad condition, permits where required, startup, and disposal.
The best comparison separates diagnostic findings, repair cost, replacement cost, required installation corrections, warranty coverage, and expected limitations.
