Water Heater Replacement Costs by Installation Type
The type of installation matters as much as the heater itself. A like-for-like swap is the least expensive; changing fuel, type or location adds plumbing, venting and electrical work.
Costs by installation type
| Installation | Typical cost | What changes |
|---|---|---|
| Like-for-like tank replacement | $600–$2,500 | Same size, fuel and location |
| Switching to tankless | $1,400–$3,900 | Gas line sizing, venting or electrical circuits |
| Moving the water heater | Added plumbing labor | New supply, drain and venting runs |
| Emergency or after-hours replacement | 1.5–3 times normal labor rates | Same work, premium timing |
