Water Heater Replacement Cost

Water Heater Replacement Cost FAQs

How much does it cost to replace a water heater?

Water heater replacement costs $900–$4,500 depending on unit type. A standard 50-gallon gas tank water heater with installation costs $1,000–$1,800. Electric tank units: $800–$1,600. Tankless gas units (higher efficiency): $2,000–$4,500. Heat pump hybrid units: $1,200–$2,800 before rebates. Labor for a straightforward swap is typically $300–$600. Complex installs involving gas line or venting changes add $500–$1,500.

Does homeowners insurance cover water heater replacement?

Homeowners insurance does NOT cover the water heater replacement itself — that's a maintenance expense. However, if the water heater fails and floods part of your home, the resulting water damage restoration IS covered under most HO-3 policies (sudden and accidental water event). The insurance pays for: water extraction, structural drying, flooring and drywall repair. The new water heater itself is out-of-pocket unless you have a home warranty.

How do I know when my water heater needs replacement?

Signs a water heater needs replacement: age over 10 years (tank units typically last 8–12 years), rust-colored hot water, rumbling or popping sounds during heating (sediment buildup), visible corrosion on the tank or fittings, water pooling around the base, inconsistent hot water. Tankless units last 15–20 years. Annual flushing and anode rod inspection can extend tank heater life by 2–5 years.

Tank vs. tankless water heater — which is better?

Tank water heaters: lower upfront cost ($900–$1,800 installed), immediate hot water, simpler maintenance. Tankless: higher upfront cost ($2,000–$4,500 installed), endless hot water, 15–20 year lifespan vs. 8–12 for tanks, lower monthly gas/electric bills. For most families who stay in a home 5+ years, the higher efficiency of tankless pays back within 6–10 years in energy savings. For homes where hot water usage is low or replacement budget is tight, a tank unit is the practical choice.

What does a home warranty cover for water heater failures?

A comprehensive home warranty (like Choice Home Warranty) typically covers: water heater repair due to mechanical failure, tank corrosion, thermostat failure, heating element failure, and in some plans, full replacement when repair isn't cost-effective. Most warranties pay $500–$1,500 toward water heater replacement. They do NOT cover: pre-existing conditions, installation modifications needed to meet current code, water damage resulting from the failure. Home warranties average $500–$800/year.

What should I do if my water heater is leaking?

Immediately: (1) Turn off the gas or electricity supply to the water heater; (2) Close the cold water supply valve at the top of the unit; (3) If flooding has spread beyond the immediate area, call for water damage extraction before the flooring or subfloor is compromised; (4) Document damage with photos for your insurance claim; (5) Do not run the water heater with a significant leak — it can worsen the failure and increase water damage. Call a plumber for the replacement and a restoration company if water spread beyond the water heater area.
