Propane tanklessWhole-home$1,600 – $3,800

What Affects the Final Price

Installation complexity: A simple swap in a garage is cheapest. Closet installs, attic installs, or units requiring new venting or gas line upgrades cost more.

Fuel-type switch: Converting from electric to gas (or vice versa) requires additional work — expect to add $300–$800.

Code upgrades: Older homes may need seismic strapping, an expansion tank, updated permits, or a drip pan — these are typically $100–$300 extra.

Brand and efficiency rating: Standard efficiency units are significantly cheaper upfront than high-efficiency or hybrid heat-pump models, but high-efficiency units save money monthly.

Best Time to Replace

Don't wait for a full failure. A leaking or failed tank can cause thousands in water damage. If your unit is 10+ years old and having issues, get quotes now. Most plumbers can install a replacement within 1–2 business days.

Water Heater Replacement FAQ

Why Hire a Licensed Plumber for Water Heater Replacement

Why Hire a Licensed Plumber for Water Heater Replacement

1. Gas Safety

Improper gas connections can cause explosions, fires, or slow carbon monoxide leaks. Licensed plumbers are trained and tested on gas piping, pressure testing, and leak detection. This is not a job for guesswork.

2. Code Compliance and Permits

Water heater installations require permits in most jurisdictions. A licensed plumber pulls the permit, schedules the inspection, and ensures the installation meets current code — including seismic strapping requirements (in earthquake zones), temperature-pressure relief valve installation, and proper venting.

3. Warranty Protection

Most water heater manufacturers require professional installation by a licensed plumber to maintain the warranty. DIY installation voids warranty coverage entirely.

4. Prevent Water Damage

Improper connections or a failed pressure relief valve can cause flooding. A licensed plumber ensures all connections are tight, the T&P valve is correctly installed and vented, and the drip pan and drain are properly configured.

5. Right-Sizing

An undersized heater means cold showers. An oversized one is wasteful. A professional assesses your household's peak demand, number of bathrooms, and fixture usage to recommend the correct capacity and fuel type.
