Most homeowners forget about their water heater until it fails. Regular maintenance not only avoids breakdowns but can also reduce power costs and extend lifespan by years. Here’s how to care for it like a professional would.

Know the System You Have

Storage tank and tankless units behave differently. A traditional tank stores heated water; a tankless heats on demand. Both need upkeep, but their weak points differ—tanks collect sediment, while tankless units need scale control.

Practical Care Routine

Monthly:

• Check for moisture around the base.
• Listen for knocking or rumbling; these sounds indicate sediment.
• Test hot water temperature—it should remain steady.

Every Six Months:

• Drain several gallons to flush out buildup.
• Check the anode rod if you have a tank; replace if heavily worn.

Annually:

• Inspect the pressure relief valve.
• Clean air vents or intake screens.
• Schedule a full professional service.

Efficiency Tips

Keep the thermostat at 120°F. It’s safe, comfortable, and uses less energy. Insulate the first few feet of both hot and cold pipes leaving the heater to minimize heat loss.

When Replacement Makes Sense

If your unit is over ten years old, repairs may cost more than a modern, efficient model. Newer systems heat faster, consume less power, and offer improved safety controls.

A water heater is a quiet workhorse. Treat it with care, and it rewards you with lower bills, consistent warmth, and fewer surprises on cold mornings.
