| 40-gallon tank | $1,300 – $5,600 |
| 50-gallon tank | $1,600 – $7,000 |
| 75–80-gallon tank | $2,200 – $9,500 |
| Tankless (gas) | $2,600 – $11,200 |

Based on Chicago pricing of $1,550–$7,000 per installed unit.
Cost by water heater scenario
Fuel type and whether the install changes venting, gas or electrical service set the price. Every row is priced against the Chicago median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Tank swap, same fuel and size | Existing connections and venting reused | $1,700 – $2,400 |
| Larger tank or relocation | New connections, pan and drain | $2,500 – $3,400 |
| Gas tankless conversion | New gas line sizing and dedicated venting | $4,200 – $6,200 |
| Heat pump water heater | Electrical circuit, condensate drain, clearance space | $3,900 – $5,600 |
| Code-required upgrades on replacement | Expansion tank, seismic or pan requirements | $2,100 – $3,100 |
- • Tankless conversion is a gas and venting project as much as a plumbing one, which is where the cost gap comes from.
- • Expansion tanks, drain pans and shutoff valves are frequently required at replacement even when the old install lacked them.
Basis: Each scope is priced as a multiple of the modeled Chicago median for water heater replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
