How Much Does a Water Heater Replacement Cost? (2026)

Water heaters last 8–12 years on average. Standard tank models (40–50 gallons) are the most affordable, while tankless (on-demand) units cost more upfront but save energy and last longer. Heat pump water heaters offer the best efficiency for homes with moderate climates.
