The biggest threat to any type of water heater is sediment and calcium buildup. The harder the water, the more quickly it can accumulate. We recommend that our customers have their water heaters tuned-up about once a year. During the tune-up, we will flush your water heater, clean it and check to make sure it is operating safely and efficiently. Annual water heater maintenance will reduce your chances of a costly repair and extend the life of your water heater. Schedule a tune-up online.
