Prescott Lakes water is high in minerals, which means scale accumulates faster inside your tankless unit. This reduces efficiency, causes error codes, and can lead to premature failure of the heat exchanger. We perform a full descaling using a descaling pump and flush kit, and we recommend a maintenance schedule based on your water hardness. We also install water filters or softeners if needed to protect your investment.
Prescott Lakes sits at a higher elevation, and winter temperatures often drop below freezing. Tankless units installed in garages or exterior walls are at risk of frozen pipes and burst heat exchangers. We inspect insulation and freeze protection on your unit and pipes. If needed, we add heat tape or recommend relocating the unit. We also advise homeowners to keep a trickle of water running during hard freezes.
Many Prescott Lakes communities have HOA rules about exterior changes, including venting and unit placement. This can complicate installation or replacement if not handled correctly. We are familiar with local HOA requirements and can advise on compliant installations. We handle the permit process and ensure venting is placed to meet both code and HOA guidelines.
Any replacement of a tankless water heater in Prescott Lakes requires a plumbing permit from Yavapai County. We pull the permit and schedule the inspection, so you don't have to worry about code violations.
While tankless water heaters don't use refrigerants, some hybrid systems might. Our techs are EPA Section 608 certified to handle any refrigerant-containing components safely.
Prescott Lakes has specific conditions that lead to certain tankless water heater problems. The hard water and cold winters are the main culprits. Here are the most common issues we see and how we fix them.
Prescott Lakes water is high in calcium and magnesium. When water is heated, these minerals precipitate and form scale on the heat exchanger walls. Over time, this restricts flow and reduces efficiency. We use a descaling pump and flush kit with a descaling solution to dissolve scale. We also recommend installing a water softener or filter to prevent future buildup.
Cold weather can affect gas pressure, and dirty burner assemblies can prevent proper ignition. Error codes like 11 or 12 are common during winter months. We clean the burner assembly and igniter, check the gas valve with a manometer, and test for gas leaks with a detector. We also verify venting is clear.
Temperatures in Prescott Lakes often drop below freezing in winter. If a tankless unit is installed in an unheated garage or exterior wall, the water inside can freeze and expand, cracking the heat exchanger. We inspect insulation and freeze protection. If needed, we add heat tape or recommend relocating the unit. We also advise homeowners to keep a trickle of water running during hard freezes.
A faulty thermistor or a clogged flow sensor can cause the unit to cycle on and off rapidly. This leads to the cold water sandwich effect, where you get alternating hot and cold water. We test the thermistor and flow sensor with a multimeter and replace them if faulty. We also check the thermostatic mixing valve to ensure it is functioning correctly.

A Rheem tankless heater in a home near the Prescott Lakes Golf Club was leaking from the pressure relief valve. We tested the water pressure and found it was too high.
