Expert Tankless Water Heater Maintenance in De Pere, WI from Hockers Home Services

When it comes to maintaining the comfort and efficiency of your home in Northeast Wisconsin, few things are as critical as your hot water supply. If you’ve invested in a modern, energy-efficient tankless water heater, you know the benefits of endless hot water and lower utility bills. However, to keep enjoying those benefits year after year, regular, professional maintenance is non-negotiable. Hockers Home Services is your trusted partner for expert Tankless Water Heater Maintenance in De Pere, Green Bay, and the surrounding Brown County area. We understand the unique challenges that the hard water and cold climate of our region present to these sophisticated systems, and we have the specialized knowledge to keep yours running flawlessly.

Why Tankless Water Heater Maintenance is Essential in De Pere and Green Bay

Unlike traditional tank-style heaters, tankless units heat water on demand, which is a marvel of modern engineering. But this process, especially in areas with high mineral content in the water—a common issue across Northeast Wisconsin—leads to a specific maintenance requirement: descaling and flushing.

The water in our region, including De Pere and Green Bay, often contains high levels of calcium and magnesium. When water is heated, these minerals precipitate out and form scale, a hard, chalky deposit. In a tankless water heater, this scale builds up on the heat exchanger, which is the component responsible for heating the water.

The Problem Scale Creates:

• Reduced Efficiency: A layer of scale acts as an insulator, forcing the unit to use more gas or electricity to heat the water. This negates the energy savings you invested in the unit for.
• Inconsistent Temperatures: Scale buildup can cause the unit to cycle on and off erratically, leading to frustrating temperature fluctuations—the dreaded “cold sandwich” effect.
• System Damage: Over time, excessive scale can cause the heat exchanger to overheat and crack, leading to costly, and often premature, system failure.
• Voided Warranty: Nearly all tankless water heater manufacturers require annual professional maintenance, specifically flushing, to keep the warranty valid. Skipping this service puts your investment at risk.

At Hockers, we view maintenance not as an expense, but as a smart, necessary investment that protects your home comfort and your wallet. Our comprehensive maintenance service is designed to address these local issues head-on.

Our Comprehensive 10-Point Tankless Maintenance Checklist

Our service goes far beyond a simple flush. We perform a detailed inspection and maintenance routine to ensure every component of your system is in peak condition.

1. System Diagnostics: We begin with a full diagnostic check of the unit’s operational status, checking for error codes and performance issues.
2. Power and Gas Shut-Off: Safety first. We securely shut off the power and gas supply to the unit.
3. Isolation Valve Connection: We connect specialized hoses and a pump to the unit’s service ports, isolating the heat exchanger from your home’s plumbing.
4. Professional Descaling Flush: We circulate a manufacturer-approved, non-toxic descaling solution (typically a food-grade acidic solution) through the heat exchanger for a minimum of 45–60 minutes. This process dissolves the mineral scale and sediment buildup.
5. Neutralization and Rinse: After the descaling, we flush the system with clean water to remove all traces of the solution and dissolved scale, ensuring the system is clean and pH-neutral.
6. Filter and Strainer Cleaning: We remove, inspect, and thoroughly clean the inlet water filter and any sediment strainers to ensure optimal water flow.
7. Condensate Trap Inspection (for condensing units): We inspect and clean the condensate trap, ensuring proper drainage and preventing potential water damage or system shutdowns.
8. Combustion and Venting Check: We inspect the air intake and exhaust venting for any blockages, leaks, or corrosion, which is vital for safety and efficiency.
9. Gas Pressure and Combustion Analysis: We verify the gas pressure and, where applicable, perform a combustion analysis to ensure the unit is burning fuel efficiently and safely.
10. Operational Test and Documentation: We restore power and gas, test the unit’s hot water output, and provide you with a detailed report of our findings and the services performed.

The Importance of Timely Service: When to Call Hockers

Manufacturers and industry experts agree: a tankless water heater should be professionally flushed and descaled at least once per year [1]. However, given the hard water conditions prevalent in De Pere, Green Bay, and much of Northeast Wisconsin, some homes may benefit from a service every six to nine months.

Signs You Need Tankless Maintenance:

• Reduced Hot Water Flow: Scale buildup restricts the internal diameter of the pipes, leading to lower water pressure at your fixtures.
• Fluctuating Water Temperature: The unit struggles to maintain a consistent temperature, often cycling between hot and cold.
• Strange Noises: Popping, rumbling, or gurgling sounds can indicate scale buildup inside the heat exchanger.
• Error Codes: Many modern units will display a maintenance or error code when they detect a performance issue caused by scale.
• Increased Energy Bills: If your gas or electric bill has inexplicably risen, your inefficient, scaled-up water heater could be the culprit.

Don’t wait for a breakdown. Proactive maintenance with Hockers Home Services is the key to maximizing the lifespan and efficiency of your tankless system.

The Unmatched Advantages of Tankless Technology

The decision to install a tankless water heater is a significant upgrade for any home in Northeast Wisconsin. Beyond the simple fact of endless hot water, these systems offer compelling long-term benefits that justify the investment:

• Superior Energy Efficiency: Tankless units only heat water when you need it, eliminating the standby heat loss common with traditional tanks. This can result in energy savings of 24%–34% compared to conventional storage tank water heaters, according to the U.S. Department of Energy [4]. In a climate like ours, where heating costs are a major concern, this efficiency translates directly into lower monthly utility bills.
• Extended Lifespan: A well-maintained tankless water heater can last 20 years or more, often double the lifespan of a conventional tank. This longevity is a key factor in the return on your investment. Our maintenance service is specifically designed to ensure your unit reaches and exceeds this expected lifespan.
• Space Savings: Tankless units are compact and wall-mounted, freeing up valuable floor space in your utility room or basement. This is a practical benefit for many homes in De Pere and Green Bay where space is at a premium.
• Reduced Risk of Water Damage: Without a large tank of water, the risk of a catastrophic tank burst and subsequent flooding is virtually eliminated. This peace of mind is invaluable, especially during our harsh winter months.

Addressing Northeast Wisconsin’s Unique Water Hardness

The single greatest threat to your tankless water heater’s performance is the water quality in our service area. Water hardness is measured by the concentration of dissolved minerals. In Brown County, including De Pere and Green Bay, water hardness levels are often categorized as moderately hard to hard.

This high mineral content means that the descaling process is not a luxury; it is a necessity. If you skip the annual flush, the scale buildup accelerates rapidly. Within a year, a significant layer of scale can form, which not only reduces efficiency but also puts immense stress on the heat exchanger.

Hockers Home Services uses commercial-grade pumps and the precise volume of descaling solution required to fully saturate and clean the heat exchanger, ensuring a complete removal of all mineral deposits. We don’t cut corners. Our thorough process ensures that when we leave your home, your tankless unit is operating as close to factory specifications as possible.

We also offer consultation on water softening solutions. While our maintenance service cleans the unit, a whole-house water softener can significantly reduce the frequency of required maintenance and further extend the life of your plumbing fixtures and appliances. We are happy to discuss these options with you during your service appointment.
