If your tankless water heater in Prairie View, IL (60069) is losing hot water output, producing error codes, cycling on and off unpredictably, or running less efficiently than when it was new, mineral scale buildup is the most likely cause. H.T. Strenger has served Northern Illinois and the North Shore since 1911, and our plumbers perform professional tankless water heater descaling and maintenance service for homes and businesses throughout Prairie View and the 60069 zip code.
Prairie View’s water supply carries elevated mineral content — primarily calcium and magnesium — that deposits as scale on the interior surfaces of tankless water heater heat exchangers. Unlike a traditional tank water heater where scale accumulates on the tank floor and around the lower heating element, a tankless unit deposits scale directly on the heat exchanger coils that are responsible for on-demand heating. As scale builds up on these surfaces, heat transfer efficiency drops, the unit has to work harder to meet the demand temperature, ignition cycles become longer, and error codes begin appearing. Left unaddressed, scale damage to the heat exchanger is the leading cause of premature tankless water heater failure.

How Scale Affects Tankless Water Heaters in Prairie View
Prairie View water — whether from the municipal supply or a private well — contains dissolved calcium carbonate that precipitates as solid scale when water is heated. In a tankless unit, this happens at the heat exchanger where water temperature rises most rapidly. Scale accumulates layer by layer over months and years of use, insulating the heat exchanger surface and progressively reducing the unit’s ability to transfer heat to the water flowing through it.
The practical effects for Prairie View homeowners are first noticed as a decline in outlet temperature consistency — the unit struggles to maintain the set temperature, especially during high-demand periods like simultaneous shower and dishwasher use. As scale worsens, the unit may produce error codes related to heat exchanger temperature limits, begin shutting down mid-use as a safety precaution, or start producing reduced hot water output even on low demand. Prairie View properties on private wells with higher dissolved mineral content typically experience scale accumulation faster than municipal water properties.
Signs Your Prairie View Tankless Water Heater Needs Descaling
- Hot water temperature is inconsistent or noticeably lower than the set temperature
- Error codes appearing on the unit’s control panel (common codes: flow sensor, heat exchanger overheat, ignition failure)
- The unit shuts off mid-shower or mid-use and requires manual reset
- Longer ignition delay before hot water arrives at fixtures
- Increased gas or propane usage without increased hot water demand
- The unit has never been descaled and has been in service for two or more years in Prairie View
H.T. Strenger’s Tankless Water Heater Descaling Process in Prairie View
1. Pre-Service Inspection
Before descaling, we inspect the unit for error codes, check the inlet filter screen, and assess the condition of the isolation valves and service ports. We note the brand and model to confirm the appropriate descaling procedure and solution — procedure specifics vary between Navien, Rinnai, Noritz, Rheem, and other manufacturers.
2. Isolation and Flushing Setup
We isolate the unit using the service ports and connect a flush pump and descaling solution reservoir to circulate food-safe descaling acid through the heat exchanger. The pump circulates solution continuously to dissolve mineral deposits from the interior heat exchanger surfaces.
3. Descaling Flush
Descaling solution is circulated through the heat exchanger for the period required to dissolve accumulated mineral deposits — typically 45 minutes to 90 minutes depending on the severity of the scale buildup and the configuration of the heat exchanger. We monitor the solution to confirm active scale dissolution is occurring.
4. Rinse and Return to Service
After descaling, we flush the system with clean water to remove all traces of descaling solution before restoring the unit to normal operation. We clear any error codes, verify ignition and operation at the set temperature, and check the inlet filter screen for any debris loosened during the flush.
