How to turn down your heating flow temperature if you have a condensing combi boiler

On a condensing boiler or combi boiler, you can usually adjust the flow temperature using the boiler’s control panel. Look for the temperature control knob and turn it counterclockwise to lower the flow temperature. Keep in mind that most combi boilers are particularly efficient at lower temperatures, making this adjustment even more beneficial for energy savings.

I have a hot water cylinder, why should I not change the hot water temperature?

If you have a hot water cylinder, changing the flow temperature to extremely low levels might not be suitable. Hot water cylinders often require higher flow temperatures to ensure an adequate supply of hot water for daily needs. Another significant consideration is that lukewarm temperatures can foster the growth of legionella bacteria. It’s essential to keep the temperature above 60 degrees.

What changes will I notice in my heating system if I lower the flow temperature?

Lowering the flow temperature may lead to slightly longer heating times, as the water takes a little more time to reach the desired temperature. However, you should still experience a comfortable indoor environment. Additionally, you will likely notice reduced gas consumption and lower bills, making the adjustment well worth it.
