Water Heater Replacement cost breakdown
At a mid-range, national-average baseline, a typical water heater replacement project is estimated at $950 to $2,800. The table below breaks the cost down so you can see where your project is likely to land.
| Type | Typical installed cost | Notes |
|---|---|---|
| Tank, electric | $1,000 to $2,800 | Lowest upfront |
| Tank, gas | $1,200 to $3,500 | Most common |
| Tankless, electric | $1,800 to $4,500 | On demand |
| Tankless, gas | $2,500 to $6,000 | High capacity |
| Heat pump (hybrid) | $2,000 to $5,500 | Most efficient |
What drives water heater replacement cost
- Type: standard tank, tankless, or heat pump.
- Fuel: gas or electric.
- Tank size or tankless flow capacity.
- Whether it is a like-for-like swap or a type or fuel change.
- Venting, gas line, or electrical upgrades.
- Regional labor rates and permits.
Key cost factors
Tank vs tankless
A standard tank is cheapest to buy and install. Tankless costs more upfront but saves space, lasts longer, and lowers energy bills by heating water on demand. Heat pump models are the most efficient electric option.
Like-for-like vs upgrade
Swapping the same type is the cheapest path. Switching from tank to tankless, or gas to electric, often needs new venting, gas line, or electrical work, which adds to the total.
Rebates
Heat pump and high-efficiency water heaters often qualify for utility or federal rebates that offset the higher upfront cost.
