Is 70 Degrees Too Hot for a Hot Water Cylinder?
Setting your hot water cylinder to 70 degrees Celsius is generally considered safe and effective for household use. This temperature helps prevent the growth of harmful bacteria, such as Legionella, while providing sufficient hot water for daily needs. However, it is crucial to balance safety and energy efficiency to avoid scalding and excessive energy consumption.
What is the Ideal Temperature for a Hot Water Cylinder?
Finding the right temperature for your hot water cylinder is essential for both safety and efficiency. While 60 to 70 degrees Celsius is a common recommendation, several factors can influence your ideal setting:
- Safety: Temperatures below 60 degrees Celsius can allow bacteria to thrive. Setting your cylinder to at least 60 degrees helps prevent this.
- Energy Efficiency: Higher temperatures can increase energy consumption. Consider insulating your cylinder to maintain heat without raising the temperature excessively.
- Comfort: Personal preference plays a role. Some prefer hotter water for showers or washing dishes, while others may find lower temperatures sufficient.
How to Adjust Your Hot Water Cylinder Temperature?
Adjusting the temperature of your hot water cylinder is a straightforward process. Here’s a step-by-step guide:
- Locate the Thermostat: Typically found on the side of the cylinder, look for a dial or digital display.
- Check the Current Setting: Note the current temperature setting before making adjustments.
- Adjust the Temperature: Turn the dial or use the digital controls to set the desired temperature, usually between 60 and 70 degrees Celsius.
- Test the Water: After adjusting, test the water temperature at a tap to ensure it meets your needs.
Benefits of Setting Your Hot Water Cylinder to 70 Degrees
Setting your hot water cylinder to 70 degrees Celsius offers several advantages:
- Bacteria Prevention: Reduces the risk of Legionella and other bacteria, ensuring safer water.
- Consistent Hot Water Supply: Provides enough hot water for peak usage times, such as mornings and evenings.
- Improved Cleaning: Hotter water can enhance the effectiveness of cleaning dishes and laundry.
Potential Risks of High Temperature Settings
While setting your hot water cylinder to 70 degrees Celsius is generally safe, there are potential risks to consider:
- Scalding Hazard: Water at 70 degrees can cause burns in seconds. Install anti-scald devices or mix cold water to reduce risk.
- Energy Costs: Higher temperatures can lead to increased energy bills. Monitor usage and consider energy-efficient practices.
How to Maintain Your Hot Water Cylinder?
Regular maintenance of your hot water cylinder is crucial for optimal performance and longevity. Here are some tips:
- Annual Inspection: Have a professional inspect your cylinder annually to check for leaks, corrosion, and thermostat accuracy.
- Insulation: Insulate your cylinder and pipes to retain heat, reducing the need for higher temperature settings.
- Sediment Removal: Drain the cylinder periodically to remove sediment buildup that can affect efficiency and water quality.

How Can I Prevent Scalding from Hot Water?
To prevent scalding, install thermostatic mixing valves that blend hot and cold water to a safe temperature before it reaches taps. Additionally, educate family members about the risks of hot water and supervise young children during bath time.
What is the Most Energy-Efficient Temperature for a Hot Water Cylinder?
For energy efficiency, setting your hot water cylinder to around 60 degrees Celsius is often recommended. This temperature balances safety and energy use, reducing costs while preventing bacterial growth.
Can I Lower My Hot Water Cylinder Temperature in Summer?
Yes, you can lower the temperature slightly in summer to save energy, as the ambient temperature is higher and less heat is lost. However, ensure it remains above 60 degrees Celsius to prevent bacterial growth.
How Often Should I Check My Hot Water Cylinder Temperature?
Checking your hot water cylinder temperature every few months is advisable. Regular checks ensure the thermostat is functioning correctly and that the water is at a safe and efficient temperature.
What Should I Do If My Hot Water Cylinder is Leaking?
If your hot water cylinder is leaking, turn off the water supply and power to the unit immediately. Contact a professional plumber to assess and repair the issue to prevent further damage and water waste.
Conclusion
Setting your hot water cylinder to 70 degrees Celsius is a practical choice that balances safety and efficiency. By maintaining this temperature, you can ensure a steady supply of hot water while minimizing the risk of bacterial growth.
