Further information on Linea One’s Energy Saving technology

The Linea One boasts an enviable modulation ratio of 10:1, this high ratio enables the boilers output to be reduced to as little as 10%. For example its 38kW output can reduce to just 3.8kW, so when the home only requires 4kW, the boiler will modulate itself down to 4kW.

Boilers with an inferior ratio, for example 4:1 would only reduce to 9.5kW, 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.

Being prepared!

The Linea One comes with some great features that can help maximise comfort for the end user, including an intelligent pre-heat on the domestic hot water. By selecting the memory function button on the display, the Linea One will memorise the customer’s domestic hot water pattern for seven days, the following seven days it will pre-heat itself to operate just before the time of day it was used during the previous week, meaning for example, that when the customer takes their morning shower, the Linea One is up to temperature and there is minimal delay in waiting for the hot water to come through!

Being in Control

The Linea One’s display module helps the customer to be in control of their heating and hot water. By activating the comfort button they can fix the temperature of the domestic hot water between 35-45°C. This can be particularly useful if there are young children or elderly relatives in the home.
