What are signs I need a new water heater?
Look out for common signs such as a decrease in hot water supply, unusual noises like rumbling or popping, visible rust or corrosion on the unit, or unexplained increases in your energy bills. If your current water heater in Bend is showing any of these symptoms, it might be time for an upgrade.
