What is boiler modulation and boiler cycling? - HeatGeek

1/11/2018 · A boilers modulation ratio is its minimum output in relation to its maximum output, stated as a fraction. i.e. a boiler with 30kW maximum output and a 5kW minimum output would be given the ration 1 to 6. An average modulation for this day and age. Typically it's accepted that the bigger/wider the modulation ratio the better.
