Frequently Asked Questions About Water Heater Repair in St. Mary, MO
Hard water is very tough on tankless heaters because the intense heat causes calcium to rapidly build up inside the narrow heat exchanger. You must have your tankless unit descaled annually to prevent irreversible damage.
Yes. Tankless systems require specialized knowledge to diagnose error codes, flush scale buildup, and clean burner assemblies. Our technicians in St. Mary, MO are experts in tankless water heater maintenance and repair.
Simply call us at (877) 415-0636. Our friendly dispatch team will take down your information and send a certified water heater technician to your home in St. Mary, MO as quickly as possible.
Yes. Sediment creates a thick layer of insulation between the burner and the water. The burner has to run longer and hotter to heat the water, which overheats and weakens the steel tank bottom, eventually causing it to fracture.
If your home is on a closed plumbing system (such as having a pressure reducing valve), thermal expansion can cause dangerous pressure spikes when water heats up. An expansion tank absorbs this pressure and protects your water heater.
