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 Sioux City median.

ScopeWhat it includesTypical installed cost
Tank swap, same fuel and sizeExisting connections and venting reused$1,100$1,600
Larger tank or relocationNew connections, pan and drain$1,700$2,300
Gas tankless conversionNew gas line sizing and dedicated venting$2,900$4,200
Heat pump water heaterElectrical circuit, condensate drain, clearance space$2,700$3,800
Code-required upgrades on replacementExpansion tank, seismic or pan requirements$1,400$2,100
  • 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 Sioux City median for water heater replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
