Heat Exchanger Descaling in Port St. Lucie
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system thoroughly. Restored flow means more stable temperatures and fewer shutdowns.

Annual Tankless Water Heater Inspection in Port St. Lucie
An annual inspection of your tankless water heater in Port St. Lucie is a proactive measure against costly repairs. Our thorough check includes examining the gas line connections for leaks, testing the pressure relief valve, inspecting the igniter and cleaning the air intake filter.
