What temperature should a condensing boiler be set at

Most modern boilers will have a digital dial that allows you to set the output temperature. For combi boilers, the recommended output temperature for the radiators is 75 °C and for the water it's 60 °C. You shouldn't need to adjust these output temperatures as you may alter the boiler's efficiency.
