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 Boston median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Tank swap, same fuel and size | Existing connections and venting reused | $1,900 – $2,700 |
| Larger tank or relocation | New connections, pan and drain | $2,900 – $3,800 |
| Gas tankless conversion | New gas line sizing and dedicated venting | $4,800 – $7,000 |
| Heat pump water heater | Electrical circuit, condensate drain, clearance space | $4,500 – $6,400 |
| Code-required upgrades on replacement | Expansion tank, seismic or pan requirements | $2,400 – $3,500 |
- • 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 Boston median for water heater replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions
Do I need a permit to replace a water heater?
Yes. Florida jurisdictions require a plumbing permit for a water heater changeout because the work involves gas or electrical connections, temperature and pressure relief piping, and drainage. Replacing without a permit can cause insurance and resale problems.
Can I replace my own water heater?
A homeowner can pull an owner-builder permit and replace a water heater in a home they own and occupy. Electrical and gas connections must still pass inspection.
How long does a water heater last?
Standard tank units last 8-12 years; tankless units often reach 15-20 years with annual descaling. Florida's hard water shortens tank life in many areas.
