 10:1 modulation explained:

The Unica i range boasts an enviable modulation ratio of 10:1, this high ratio enables the boiler output to be reduced to as little as 10%.

For example the 28kW Unica i can reduce its output to just 2.8kW, so when the home only requires 3kW, the boiler will modulate itself down to 3kW.  Boilers with an inferior ratio, for example 4:1 would only reduce to 7kW, resulting in wasteful on/off cycling and reduced efficiency. A high modulation ratio can significantly reduce wasteful on/off cycles, which in turn, will increase component longevity and helps to ensure stable domestic hot water temperatures.

In simple terms; 10:1 modulation = better fuel efficiency, increased component longevity, optimal comfort.
