What Impacts the Total Price?
The cost depends on:
- Heater type (tank vs tankless)
- Gallon size / family size needs
- Gas vs electric
- Accessibility (attic, garage, basement)
- Permits in certain states
- Emergency or same-day installation fees
Older homes often need:
- Pipe upgrades
- New venting or gas line work
- Drip pan & drain line replacement
When You Should Replace (Not Repair)
Replace your water heater if:
- It’s 10–15+ years old
- It leaks from the bottom of the tank
- Water is rusty or smells metallic
- You hear popping/banging noises
- Repairs exceed 50% of replacement cost
At this point, replacement is a better investment.

|---|---|
| Expansion tank | +$150–$350 |
| Code compliance updates | +$200–$600 |
| Disposal of old tank | +$50–$150 |
| Gas line work | +$300–$900 |
Always ask for a written quote before work begins.
