What Temperature Should My Boiler Be Set At For Hot Water UK?

Setting your boiler to the right temperature is important for keeping your home warm and ensuring enough hot water for your daily needs. However, it can be confusing to know “what temperature should my boiler be set at for hot water in the UK. 

In the UK, the recommended settings for a boiler can vary depending on your system type and your personal comfort preferences. Let us break it down so it is easy to understand.

Ideal Temperature for a Combi Boiler

If you have a combi boiler, a popular choice in the UK because it provides both heating and hot water directly from the boiler, the temperature settings are crucial. For hot water, the general recommendation is to set the temperature between 50°C and 60°C. 

To set your boiler within this range ensures that the water is hot enough to kill harmful bacteria, such as Legionella, while also being safe enough to avoid scalding.

Setting the temperature too high can result in energy waste and potentially dangerous water temperatures. On the other hand, setting it too low might not heat your water sufficiently, leading to lukewarm water that is not ideal for bathing or cleaning.

What About Central Heating?

The recommended temperature setting for your central heating is generally lower than that for hot water. Most experts suggest setting your boiler’s central heating temperature to around 65°C to 75°C. This will keep your home warm without overheating, which can lead to higher energy bills and an uncomfortable living environment.

If you want to be more energy-efficient, consider setting the temperature slightly lower, around 60°C, especially if your home is well-insulated. This can help you save on your energy bills while still keeping your home comfortable.

Should You Adjust the Boiler Temperature?

Yes, adjusting your boiler temperature depending on the season and your needs can be beneficial. For example, in the summer months, you might not need your central heating, so you can lower the boiler temperature or even turn off the heating function. During the winter, you may want to increase the temperature slightly to ensure your home stays warm.

It is also worth noting that modern boilers often come with a thermostat or an eco-mode setting that adjusts the boiler automatically, ensuring that your home is heated efficiently. If your boiler has these features, use them to optimise your energy usage.

Energy-Saving Tips

If you are looking to reduce your energy consumption and save on bills, here are a few tips:

• Ensure that your thermostat works correctly and set it to a comfortable temperature, usually between 18°C and 21°C for your living spaces.
• Lowering the flow temperature on your boiler can help reduce energy usage. A flow temperature of around 55°C is often recommended for better efficiency without compromising comfort.
• A well-insulated home retains heat better, so you can keep your boiler settings lower and stay warm.
• Make sure your boiler is serviced regularly to keep it running efficiently. A well-maintained boiler will use less energy to heat your home and water.
