Durham Water Heaters

A slow-heating water heater may be caused by sediment buildup, a faulty heating element, or incorrect thermostat settings. Older units can also lose efficiency over time. Flushing the tank or replacing damaged components can help improve performance.

The right size depends on the number of people in your household and your daily hot water usage. A family of four typically needs a 50-gallon tank, while larger families may require more. Tankless systems are also a good option for continuous hot water supply.

Lowering the thermostat to 120°F, insulating the tank and , and scheduling regular maintenance can all improve energy efficiency. Flushing sediment out of the tank helps maintain heating performance. Upgrading to a high-efficiency or tankless model can also reduce energy costs.

Discolored or rusty water can result from corrosion inside the tank or a failing anode rod. If only the hot water is affected, the issue is likely within the water heater itself. Replacing the anode rod or flushing the tank can often resolve the problem.

Water heaters must be installed in areas with proper ventilation, drainage, and easy access for maintenance. Local codes may restrict placement in certain rooms, such as bedrooms or closets without ventilation. A licensed plumber can help determine the safest and most efficient location.

Traditional tank water heaters last 8–12 years, while tankless models can last up to 20 years with proper care. Regular maintenance, like flushing and anode rod replacement, can extend their life. If your unit is nearing the end of its lifespan, consider a proactive replacement to avoid sudden failure.

Rumbling or popping noises are usually caused by sediment buildup at the bottom of the tank. As water heats, steam bubbles form under the sediment, creating these sounds. Flushing the tank regularly helps eliminate the buildup and quiet the operation.

No, even small leaks should be taken seriously, as they can indicate a faulty valve, corrosion, or pressure issues. Over time, minor leaks can worsen and cause water damage. It’s best to have any leak inspected by a professional plumber right away.
