Signs your tankless water heater needs maintenance
No Hot Water
When your tankless water heater stops producing hot water altogether, the issue could be related to ignition failure, electrical components, gas supply problems, or internal sensors. Our technicians diagnose the root cause and restore hot water quickly.
No Hot Water
Inconsistent or Fluctuating Water Temperature
If your water turns hot and cold unexpectedly, your tankless system may be undersized, experiencing flow issues, or dealing with scale buildup. We identify the cause and make adjustments or repairs to stabilize performance.
Inconsistent or Fluctuating Water Temperature
Error Codes or System Shutdowns
Tankless water heaters are designed to shut down when something is wrong. Error codes often point to airflow problems, overheating, sensor issues, or maintenance needs. We interpret the codes and resolve the underlying issue safely.
Error Codes or System Shutdowns
Mineral or Scale Buildup Inside the Unit
Hard water can cause mineral deposits to collect inside your tankless system, reducing efficiency and restricting water flow. Professional flushing and maintenance remove buildup and help prevent future damage.

Ignition or Burner Problems

Tankless water heater systems heat water as it flows
Tankless water heaters deliver hot water when you need it without the wait or the energy cost of heating and storing large volumes of water. Instead of heating a full tank, these systems activate only when a tap is turned on or an appliance calls for hot water. That means:
Hot water on demand for showers, laundry, dishes, and more
Reduced standby energy loss that traditional tanks experience
Lower utility bills because water is heated more efficiently
Longer system life when properly installed and maintained
If your household struggles with hot water shortages or you are upgrading to an energy-efficient system, tankless technology may be the right fit. Our team at Gold Medal helps you choose a system sized to your home’s specific hot water usage while considering fuel type, venting needs, and installation requirements.
Tankless water heaters offer modern comfort and efficiency
Tankless water heaters provide hot water on demand, which means your system heats water only when you need it. Unlike traditional tank systems that store and reheat water all day, tankless units operate more efficiently and support today’s busy households. When properly installed and maintained, a tankless water heater can deliver reliable performance, lower energy usage, and long-term value for your home.
Benefits of tankless water heaters include:
Endless Hot Water: Tankless systems heat water as it flows through the unit, so you are not limited by tank capacity. This is ideal for households with multiple bathrooms or high hot water usage.
Improved Energy Efficiency: Because water is heated only when needed, tankless water heaters often use less energy than traditional tanks, which can help reduce monthly utility costs.
Longer System Lifespan: Tankless water heaters typically last longer than standard tank models when properly maintained, making them a smart long-term investment.
Space-Saving Design: Compact wall-mounted units take up far less space than bulky storage tanks, freeing up room in utility areas or closets.
Consistent Water Temperature: Advanced controls help maintain steady water temperature, reducing sudden temperature changes during use.
Low Risk of Water Damage: With no large storage tank, the risk of leaks or catastrophic tank failure is significantly reduced.
Warranty Protection: In addition to a top-tier installation, your tankless water heater system is backed by the industry’s best warranty.

Tankless water heaters heat water on demand rather than storing it in a tank. This means you get hot water whenever you need it, without waiting for a tank to refill and reheat. It also reduces energy use since the system only heats water when necessary.
Yes. Because they only heat water as it flows through the unit, tankless systems use less energy than traditional tank water heaters, which continuously heat and store water. Over time, this can lead to noticeable savings on your utility bills.
We recommend annual maintenance, which usually includes flushing to remove mineral buildup, inspecting components, and checking system performance. Regular care keeps your system efficient and reliable.
Error codes indicate a specific issue, such as a sensor fault, ignition problem, or flow restriction. Contact Gold Medal to diagnose and resolve the problem safely.
