Definition
Your water heater converts cold water into hot—it's one of the most important systems in your home. Most tank heaters last 8-12 years before they give out; proper maintenance extends life.

Traditional tank water heaters store 30-80 gallons of heated water; tankless models heat water on-demand without storage. Tank heaters typically last 8-12 years; improper maintenance shortens lifespan. Common problems include sediment buildup reducing efficiency, corrosion, failing pressure relief valves, and leaks. Energy efficiency varies significantly; upgrading to high-efficiency models saves money. Inspectors assess age, condition, temperature setting (120°F recommended), and safety features.
Pro Tip
Drain your water heater annually to remove sediment that reduces efficiency. Replace the anode rod every 3-5 years to prevent tank corrosion.
Example
An inspection revealed a 15-year-old water heater showing rust spots on its exterior and producing rusty water. The pressure relief valve wasn't functioning properly. Replacement with an efficient 50-gallon gas water heater cost $1,400 and improved hot water availability.
