Understanding Discharge Temperature
Discharge temperature refers to the temperature at which hot water exits an appliance, typically measured in degrees Fahrenheit or Celsius. In most homes, the optimal discharge temperature ranges between 120°F and 140°F (49°C and 60°C). When discharge temperatures exceed this range, signifying “high discharge temperature,” it can lead to discomfort and potential scalding.
Causes of High Discharge Temperature
- Malfunctioning thermostat: A faulty thermostat can fail to regulate water temperature accurately, resulting in excessive discharge temperatures.
- Defective pressure-reducing valve (PRV): A PRV malfunction can restrict water flow, causing pressure to build up in the water heater, leading to higher discharge temperatures.
- Sediment buildup: Over time, sediments can accumulate in the water heater and clog the heat exchanger, reducing heat transfer and increasing discharge temperatures.
- Improper water heater settings: Some water heaters may have adjustable temperature settings. Inadvertently setting the temperature too high can cause high discharge temperatures.
- Age and deterioration: As water heaters age, components such as the heating element and thermostat may deteriorate, affecting temperature regulation.
Strategies to Lower High Discharge Temperature
Addressing high discharge temperature requires a multifaceted approach. Consider the following strategies:

1. Adjust Water Heater Thermostat
If adjustable, lower the water heater thermostat setting to approximately 120°F (49°C). This will reduce the water temperature entering your pipes.
2. Inspect and Replace Thermostat
A faulty thermostat can lead to inaccurate temperature regulation. Disconnect the power supply to the water heater and remove the thermostat. Check for any damage or loose connections. If necessary, replace the thermostat with a compatible model.
3. Examine Pressure-Reducing Valve (PRV)
Locate the PRV and check for signs of wear or leaks. If the PRV is malfunctioning, it should be replaced to ensure proper water pressure.
4. Flush Water Heater
Sediment buildup can compromise the efficiency of the water heater. Flush the water heater annually to remove sediment and improve heat transfer.
5. Consider a Mixing Valve
A mixing valve can be installed to blend hot and cold water before it reaches the faucet. This reduces the discharge temperature at the point of use.
6. Replace Heating Element
A faulty heating element can cause the water heater to overheat. If other methods have failed to resolve high discharge temperature, consider replacing the heating element.
Expert Advice for Preventative Measures
In addition to addressing high discharge temperature, proactive measures can help prevent future occurrences:
- Regular maintenance: Schedule regular maintenance inspections with a qualified plumber to ensure the water heater is operating optimally.
- Use low-flow fixtures: Low-flow showerheads and faucets can reduce water consumption and maintain cooler discharge temperatures.
- Insulate water pipes: Insulating hot water pipes minimizes heat loss, maintaining higher water temperatures at the point of use.
- Consider a tankless water heater: Tankless water heaters provide hot water on demand, eliminating the need for a large storage tank that can accumulate sediment.
Frequently Asked Questions (FAQs)
- Why is high discharge temperature a concern?
High discharge temperature can lead to discomfort and potential scalding, especially for children and the elderly.
- How can I prevent high discharge temperature from recurring?
Regular maintenance, installing a mixing valve, and considering a tankless water heater can help prevent high discharge temperature from reoccurring.
- Is it safe to use appliances with high discharge temperature?
While appliances with high discharge temperature may be usable, it’s recommended to address the issue promptly to avoid discomfort or safety hazards.
- Can low water pressure contribute to high discharge temperature?
Yes, low water pressure can restrict flow, causing the water heater to overheat and increase discharge temperature.
- Should I hire a plumber to fix high discharge temperature?
If you are not comfortable performing the repairs yourself, it is advisable to hire a licensed plumber who can diagnose the issue and provide a safe solution.
How To Fix High Discharge Temperature
