Heat Exchanger Descaling in Aberdeen
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.

Inlet Filter and Air Intake Cleaning in Aberdeen
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading accurately and the burner breathing properly.
Preventative Maintenance for All Tankless Brands in Aberdeen, SD
HWR Plumbing provides preventive maintenance for all major tankless water heater brands, including Navien, Bosch and State, across Aberdeen, SD. Our technicians are cross-trained to handle the unique requirements of each manufacturer. We perform descaling, filter cleaning and component checks tailored to your specific model, supporting long-term reliability and manufacturer warranty requirements, regardless of the brand.
Maintenance Cost Versus Repair Cost in Aberdeen, SD
A tankless descaling visit usually costs far less than replacing a scaled heat exchanger, which can run $600 to $1,500 or more in parts and labor. Some manufacturers deny exchanger claims when scale damage is found. Regular maintenance helps protect a unit that can last 20 years when cared for. We help you decide whether a softener or scale inhibitor would lower your long-term costs too.
Emergency Tankless Water Heater Service in Aberdeen, SD
Even with regular maintenance, unexpected issues can arise with tankless water heaters. If you experience a sudden loss of hot water, error codes or unusual noises from your unit in Aberdeen, SD, HWR Plumbing offers emergency services. We focus on rapid response to diagnose and resolve critical problems, often related to clogged heat exchangers or faulty sensors, restoring your hot water supply quickly and safely.
Residential Tankless Water Heater Flushing in Aberdeen
Many rural homes in South Dakota draw from private wells or rural water systems, and a water test is the best way to know what comes out of the tap. Hard water can lead to significant mineral buildup in tankless water heaters. Our residential flushing service in Aberdeen involves circulating a descaling solution through your unit's heat exchanger to remove calcium and magnesium deposits. This process restores efficiency, prevents overheating and extends the life of your appliance, so your family gets continuous hot water without interruption.
Error Code Diagnostics in Aberdeen, SD
Codes like Rinnai LC, Navien E003 or Noritz 90 tell us a lot about what is going wrong. We read the code history, test flame rods, flow sensors and igniters and check gas pressure at the inlet. Many codes trace back to scale or a dirty filter and clear after maintenance. When a part has failed we explain the repair and the cost before doing anything.

Isolation Valve Kit Installation in Aberdeen, SD
Some tankless heaters were installed without service valves, which makes proper flushing impossible. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in simpler service.
