Water Heater Replacement: What It Costs and When to Stop Repairing
August 24, 2026 · 5 min read · by the YourLead team
The water heater is the appliance nobody thinks about until the shower goes cold, or the garage floods. It is also one of the most common projects posted on YourLead, so here are the real numbers.
The 2026 numbers
Angi’s 2026 data puts a standard tank replacement at $881 to $1,825, averaging about $1,346 installed. By capacity, a 40-gallon runs roughly $800 to $2,300 and a 50-gallon $800 to $2,500. Tankless is the premium path at $1,400 to $3,900 installed, with labor alone at $600 to $1,900 because venting and gas or electrical work is more involved.
| Type | Installed range | Good to know |
|---|---|---|
| Tank, 40 gallon | $800 to $2,300 | The standard family size |
| Tank, 50 gallon | $800 to $2,500 | Worth it for 3+ bathrooms |
| Tankless | $1,400 to $3,900 | Endless hot water, higher install cost |
The hidden line items
- Permits: $25 to $300, and yes, Florida municipalities require one for a water heater swap. Unpermitted swaps surface at resale inspections.
- Gas line work when switching fuel or moving the unit: $260 to $820.
- Electrical upgrades for tankless electric: $500 to $1,000 or more, they draw serious amperage.
- Water line changes: $400 to $2,000 when the new unit does not line up with the old plumbing.
Repair or replace?
The practical rule: a tank heater past 10 years old, or any heater where the tank itself leaks, gets replaced, not repaired. A leaking tank never gets better, and in Florida garages and closets it usually announces itself as a flood. If yours is past 8 years, replacing on your schedule beats replacing during an emergency, at emergency pricing, with water on the floor.
