Combi boilers have controls on the unit which allow you to set the temperature of the water that will be circulating around the central heating system and out of the taps. The best setting for combi boilers is often recommended as 75°C for central heating and 60°C for domestic hot water.
What temperature should I Set my combi boiler to?
The installers of my recently fitted combi have set the domestic hot water temperature to 52C and the CH temperature to 72C. The water temp is a bit lower than our old boiler but fine by us - probably a more appropriate temp. As for CH temperature - I think it's best to think more about the setting on your room thermostat.

What temperature should tap water be set at at the boiler?

Should a boiler be hot or cold?

The ideal temperature for domestic hot water is 120 degrees Fahrenheit, or 49 degrees Celsius, to avoid the possibility of scalding. Furthermore, if the water heater is set at too high a temperature, it can result in unnecessarily more expensive energy bills from the running water emerging from shower systems and taps.

I have a Combi boiler. I'm wondering: what's the lowest temperature that I can set the supply to taps at please? I don't have mixer taps in the house and really don't want 60C hot water coming out of the taps.
ianmcd
you wont get 60 C with a combi, the way a combi works is that faster the water flows through the boiler the colder the tap temp will be, the faster you run the tap the colder the water will be , the slower you run the tap the hotter it will be , but the boiler wont let you have 60C water temperature , you are mistaking system boilers where the water has to be stored at that temp to prevent legionella.
Juliesm
Hmm. Thank you for your answer. Now then, if I understand you correctly, the temperature I set at the boiler, will not have a positive or negative effect on the growth of legionella in my pipes.

Thanks Madrab Your answer is exactly what I thought. My landlord, housing association, stipulates that the tap water temperature at the boiler should be set at 60C. I usually have it at 42C so that I don't burn my hands. I can't figure out why they say to keep it at 60C, since as you so rightly pointed out "it's mains water".
Madrab
They'll be using it as a coverall to cover their ass if there were any subsequent problems. As suggested, that approach is for stored hot water.

Thanks hard-work. In my experience, the longer I leave the tap running the hotter the water gets. That's why I have mine set at 42C.
How cold is a combi boiler?
With a combi boiler, the water is heated as it flows in from your mains water supply. The incoming water will be pretty cold (around 8-10°C in winter) - At this temperature, the Legionella bacteria can not survive any appreciable length of time, and the water company would have treated the water to eliminate the risk.
Why is the dew point temperature important for a boiler?
This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature. The dew point temperature is a measurement that determines the humidity of air and is the temperature ...

What is a condensing boiler?
Condensing boilers have a Flue Gas Heat Recovery System, not found in non-condensing units, which captures heat from waste gases to preheat cold water from the mains as it enters the boiler. In non-condensing units, this heat from waste gases would be lost, so by making the most of this heat, condensing units use less energy, ...
