Frequently Asked Questions About Water Heater Installation in Denison, IA

A sulfur odor is usually caused by anaerobic bacteria in your water supply reacting with the tank's magnesium sacrificial anode rod. Our technicians in Denison, IA can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
You can improve efficiency by insulating hot water pipes, installing an external fiberglass tank blanket (on electric models), flushing sediment, and setting the thermostat to a safe, efficient 120°F (49°C).
A cold water sandwich happens when hot water left in the pipes is followed by a brief surge of unheated water while the flow sensor triggers the burner. Installing an internal or external recirculating buffer tank eliminates this issue completely.
A healthy gas flame should burn a crisp, clean blue. A lazy yellow flame indicates incomplete combustion, dirty burner air shutters, or carbon monoxide hazard. Have Expert Water Heater Pros inspect the burner assembly immediately.
A hissing sound in gas heaters often occurs when condensation drips onto the hot burner assembly. Whistling usually indicates restricted water flow through a valve or excessive internal pressure escaping past a safety seal.
