About this scenario

Installed cost to replace an existing tank-style natural gas water heater with a like-for-like 50-gallon unit (40-50 gal class), including standard venting reconnect, haul-away and permit. Not a quote: ranges are national installed-cost bands from independent cost guides.

What moves this number:

  • tank size (30-80 gal)
  • vent type (atmospheric vs power/direct vent)
  • code-required upgrades (drip pan, seismic strapping, expansion tank, TPR discharge)
  • permit and haul-away fees

Dataset verification notes:

  • Fixr 50-gal gas band $900-$2,500 with ~$1,800 typical; HomeAdvisor 50-gal band $800-$2,500 overlaps; Fixr 40-gal gas band $700-$2,300.
  • Equipment-only reference: conventional 50-gal tank unit runs roughly $500-$1,000 (Rheem cost guide).

How the estimate works

Each scenario maps to a costed product in our dataset, and the calculator renders that product's installed range — equipment plus labor, per the unit definition shown with the result. Where the dataset publishes unit-only and labor bands, the calculator splits them out so you can see what you're paying for. Nothing is scaled, inflated, or invented: when a figure is derived or carries lower confidence, the flag travels with it.

What these national bands can't do: price your local labor market, quote a permit in your jurisdiction, or predict what code-required upgrades (pan, strapping, expansion tank) your inspection will demand. Get local written quotes before budgeting.
