Comprehensive Tankless Water Heater Maintenance in Houston
The Engineering Behind Heat Exchanger Scaling
The technical sophistication of a tankless water heater is what makes it so efficient, but it is also what makes maintenance a necessity. Inside the unit, water passes through a series of narrow fins in the heat exchanger where it is subjected to intense heat. In the Houston area, the mineral content in the water precipitates out of the liquid state during this heating process and bonds to the metal surfaces.
Thermal Resistance and Energy Waste
As this mineral layer grows, it creates thermal resistance. In simple terms, the burner has to stay on longer and burn hotter to push heat through the scale and into the water. This increased "run time" leads to higher gas or electricity consumption and places undue stress on the blower motor and gas valves. A system that is not descaled annually can lose up to 20% of its efficiency in a relatively short period, effectively erasing the energy savings you expected when you purchased the unit.
Preventing Heat Exchanger Stress Fractures
The most dangerous result of scale buildup is localized overheating. Because the scale prevents water from cooling the metal of the heat exchanger, the metal can reach temperatures far beyond its design limits. This causes the metal to expand and contract more violently during each cycle, eventually leading to stress fractures or "pinhole" leaks. Once a heat exchanger develops a leak, the entire unit usually requires replacement. Our professional flushing service is the only way to ensure these mineral deposits are completely removed, keeping the metal at safe operating temperatures.
Cleaning the Inline Water Filter
Many homeowners forget that tankless units also have a physical inline water filter designed to catch larger sediment and debris from the Houston city water lines. If this filter becomes clogged, it restricts the flow rate of the unit, which can prevent it from firing entirely or cause the water temperature to fluctuate wildly. Part of our technical maintenance includes a full cleaning of all filters and screens to ensure maximum water flow.
Ensure Peak Performance with Regular Maintenance from Hot Water Guys
Ensuring System Uptime with Proactive Care
A tankless water heater is a significant investment in your home’s comfort and infrastructure. To ensure you get the maximum value out of your system, it is vital to choose a partner that offers more than just emergency repairs. Hot Water Guys provide comprehensive maintenance support throughout the entire lifecycle of your water heater, from the first year of installation until the end of its 20-year lifespan.
Validating Your Manufacturer Warranty
Most homeowners are unaware that the "15-year" or "25-year" warranty provided by manufacturers like Rinnai or Navien is often conditional. If a heat exchanger fails due to scale buildup and you cannot provide proof of annual professional maintenance, the manufacturer may deny your claim. Our service provides you with the documentation you need to prove your system has been cared for by certified professionals, protecting you from massive out-of-pocket replacement costs down the road.
Safety Inspections and Gas Pressure Tuning
Maintenance isn't just about water; it's about safety. Our technicians inspect the venting system for any obstructions -such as bird nests or debris -that could lead to carbon monoxide backing up into the home. We also check the gas pressure to ensure the unit is receiving the exact amount of fuel required for a clean, complete burn. An improperly tuned burner can lead to "sooting," which further reduces efficiency and creates a fire hazard.

any questions?
It's recommended to perform maintenance on your tankless water heater at least once a year. Regular maintenance helps prevent mineral buildup, ensures efficient operation, and extends the system’s lifespan.
Maintenance typically includes descaling to remove mineral buildup, cleaning the air filter, checking the burner or heating element, and inspecting the venting system. Regular checks ensure that all components are functioning correctly.
While some basic maintenance tasks like cleaning the air filter can be done by homeowners, it’s best to have a professional perform thorough maintenance to ensure all components are properly inspected and serviced.
Signs include inconsistent water temperature, reduced water flow, strange noises, or error codes displayed on the unit. These symptoms indicate potential issues that require professional attention.
Regular maintenance can significantly extend the lifespan of your tankless water heater by preventing issues that could lead to costly repairs or system failure. It ensures the unit operates efficiently and reliably over its lifespan.
