Tankless Water Heater Repair & Descaling near me in Cathedral City
Tankless water heaters heat water on demand as it flows through a heat exchanger. In very hard water, minerals deposit in those narrow passages, reducing efficiency and flow, overheating the exchanger and triggering error codes. Inlet filters also clog with sediment.
Regular descaling — flushing the unit with a descaling solution through service valves — is the key maintenance task. Repairs may involve flow sensors, igniters, flame rods, fans and venting. For tankless water heater repair near me, call (760) 273-8147.
