| 50-gallon tank | $1,400 – $6,100 |
| 75–80-gallon tank | $1,900 – $8,200 |
| Tankless (gas) | $2,200 – $9,800 |

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 Annapolis median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Tank swap, same fuel and size | Existing connections and venting reused | $1,400 – $2,000 |
| Larger tank or relocation | New connections, pan and drain | $2,200 – $2,900 |
| Gas tankless conversion | New gas line sizing and dedicated venting | $3,600 – $5,300 |
| Heat pump water heater | Electrical circuit, condensate drain, clearance space | $3,400 – $4,800 |
| Code-required upgrades on replacement | Expansion tank, seismic or pan requirements | $1,800 – $2,600 |
- • 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 Annapolis median for water heater replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
