Determining the best temperature for a central heating boiler can be challenging, as there is no single temperature that is suitable for all households. The temperature at which you set your boiler will depend on several variables, including the weather and personal preference. Ideally, you should adjust the boiler temperature to keep it within a specific temperature range to prevent the boiler from overheating.
Recommended temperature settings for central heating boilers vary depending on the source, but most suggest that low-temperature settings should be within the range of 120-160 degrees Fahrenheit, while high-temperature settings should be within the 180-200 degree Fahrenheit range. It is also important to note that the temperature of the water in the boiler should not be set any lower than 60 degrees Celsius to ensure that the hot water cylinder is heated to 60 degrees Celsius.
When setting the temperature for the heating water, it is best to adjust your boilers high/low temperature settings as the weather gets warmer and colder. While low boiler temperatures are more efficient and comfortable in the summer, higher boiler temperatures are more suitable for the winter. Ultimately, the best temperature for your central heating boiler will depend on your specific circumstances, and it may be helpful to consult with a heating professional to determine the ideal temperature range for your home.
