How much does it cost to replace a water heater in Las Vegas?
A standard 40–50 gallon water heater replacement in Las Vegas costs about $1,800–$3,200 installed, including permit, expansion tank, strapping, and haul-away. Tankless conversions run $4,500–$7,500 because they typically require a larger gas line, new venting, and a condensate drain.
What should be included in the price
A code-compliant install includes the permit, a thermal expansion tank, seismic strapping, a drain pan with a routed drain line, correct venting, new flex connectors, and removal of the old tank. If those show up as surprise add-ons after the truck arrives, the original quote was not a real quote.
Why Las Vegas tanks fail early
Valley water averages 16–17 grains per gallon of hardness. Sediment layers on the bottom of the tank, insulates the burner from the water, and cooks the steel. That is why local heaters commonly need replacement at 8–12 years rather than the 12–15 the label promises. Annual flushing and a softener are the two things that measurably extend life here.
