Before agreeing to Water Heater Replacement
Ask the provider
Is this a like-for-like replacement or a conversion? Which permit and code upgrades are included? Does the price cover removal, venting, valves, drain pan, expansion control, and the manufacturer's labor warranty?
Watch for
A cheap tankless quote that ignores gas-line capacity and venting, a standard tank installed where a power-vent model is required, or an installer who won't put the exact model number and included code work in writing.

Check your price and see how it compares in secondsWhat drives the price of Water Heater Replacement
Water-heater replacement starts with tank capacity or, for tankless units, required flow rate and temperature rise. Fuel type matters because gas, electric resistance, heat-pump, and tankless heaters need different venting, wiring, gas supply, clearances, and drainage. Moving the heater, changing its type, or installing it in an attic can turn a straightforward swap into plumbing, electrical, and carpentry work.
A surprisingly large share of the bill can be code upgrades. A replacement may require a thermal expansion tank, drain pan and drain line, seismic strapping in some states, new shutoff valves, vent changes, a gas sediment trap, or a dedicated electrical circuit. Tankless conversions may also require a larger gas line, new exhaust routing, condensate handling, and annual flushing provisions.
