Water Heater Cost Calculator
Estimate water heater replacement cost by heater type, household size, venting scope, and state.
Heater and household
Installation and location
Storage tanks cost less upfront. Tankless and heat pump models cost more to install but can cut standby losses or annual utility bills.
A same-location swap is the cheapest path. Conversions and relocations usually add labor, gas, venting, or electrical work.
Household size is a simple proxy for first-hour demand. Larger families need bigger tanks or more tankless flow capacity.
Closets, attics, stairs, and other tight spaces increase labor and disposal time. Garage and utility-room swaps are usually easier.
Tank sizes map to common household demand ranges. Tankless models are sized by whole-home flow rate in gallons per minute.
Suggested for this setup: 50-gallon
Gas units often need vent-path upgrades. Tankless systems use manufacturer-approved venting, while heat pump units may need airflow or condensate adjustments.
Value brands keep equipment cost lower. Premium models often add warranty length, smart controls, or stainless heat exchangers.
Many installs need permits plus expansion tanks, drain pans, seismic strapping, or relief-valve updates. Conversions can also trigger gas or electrical changes.
Emergency after-hours replacement usually carries an overtime premium, especially nights and weekends.
Regional labor, permit cost, and code requirements change the installed total. Use your state for a closer planning range.
A contingency helps cover hidden corrosion, shutoff valve replacement, vent fixes, drain pan upgrades, or additional permit corrections.
