What to Do If Your Tankless Water Heater’s Water Is Too Hot?

by Madison Dean

Tankless water heaters are the preferred choice among homeowners for their efficiency and effectiveness. However, sometimes things don't always go as planned, and the water temperature can spike and become too hot. While this problem is not uncommon, it is essential to tackle it immediately to avoid safety hazards and prevent potential damage to your system. This blog covers some quick and easy solutions to address the problem.

Check the temperature setting
The first thing you should do when your tankless water heater's water is too hot is to check the temperature setting. Tankless water heaters have temperature controls that enable you to customize the heat output based on your individual preferences. If the temperature is too high, it could be because of a mistake in setting the thermostat, causing the water temperature to climb. In such instances, adjust the temperature setting immediately, and the problem should be resolved.

Flush the system
Your tankless water heater could produce too-hot water because of mineral build-up within the unit. Over time, these minerals collect within the heat exchanger, reducing its efficiency and causing the water temperature to spike. You can address this problem by flushing the system to remove the mineral build-up. Flushing your tankless water heater should be performed annually, and you can do it yourself or hire a professional.

Check the pressure relief valve
Another reason why your tankless water heater’s water is too hot could be because of a faulty pressure relief valve. The pressure relief valve is a safety measure, preventing the pressure within the system from surpassing dangerous levels. If it’s not working correctly, it could result in the water temperature climbing too high. If you suspect your pressure relief valve is faulty, shut off the gas and water supply to your unit and call a professional to replace the valve.

Consider a professional inspection
If you have tried all the above checks and still have hot water coming from your tankless water heater, it might be time to call a professional for an inspection. Sometimes, your system could be faulty, and a professional inspection is necessary to detect the problem correctly. An inspection could help you identify any underlying problems early and decrease the chances of severe damage to the system.

The issues listed above are not exhaustive. Still, they are the most common reasons why your tankless water heater's water could be too hot. Addressing the problem immediately is crucial to avoid potential damage to the system and also prevent any safety hazards. If you need professional tankless water heater repair services, contact a local company.
