Your boiler controls explained To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you've got your boiler running at the optimal temperature, you'll want to set the timer for when you need heating the most. With a combi boiler, hot water is on demand..
Also asked, what temperature do you set your boiler to?
Modern boilers will have a digital dial where you can set the output temperature. For combi boilers it is recommended to set the output temperature for the radiators at 75 degrees and the water temperature at 60 degrees.
Furthermore, what temperature should my Glow Worm boiler be set at? Try to run the flow temperature at 65 degrees,and the return should ideally be 55 or less,this allows the boiler to condense and run more economically.
Similarly, you may ask, what temperature should my Vaillant boiler be set at?
If the boiler is heating hot water then it will need to be set at least 5-6° above the target hot water temperature which is ideally set to 55° making the boiler need to be at least 60°.
What temperature should central heating be set at?
Your room thermostat should be set to the lowest comfortable temperature, typically between 18 and 21 degrees. You don't need to turn your thermostat up when it is colder outside; the house will heat up to the set temperature regardless.
