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 Baltimore median.

ScopeWhat it includesTypical installed cost
Tank swap, same fuel and sizeExisting connections and venting reused$1,400$2,000
Larger tank or relocationNew connections, pan and drain$2,200$2,900
Gas tankless conversionNew gas line sizing and dedicated venting$3,600$5,300
Heat pump water heaterElectrical circuit, condensate drain, clearance space$3,400$4,800
Code-required upgrades on replacementExpansion 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 Baltimore 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.
