Boiler temperature with the ETS is controlled by a dual stage thermostat which is set by the user to give the desired boiler
temperature.When the boiler has heated up to within 7°C of the set temperature,the thermostat switches off one power stage and
therefore reduces the heat input.
Thanks to this simple but effective form of modulation,the ETS has longer working cycles and requires less stops and starts,thus
resulting in a more even temperature across the boiler.It also means less wear and tear on components and importantly,it uses less
power once it has reached working temperature.
