3. Simple handled system design

Fully automatic with ignition, output adjustment and daily cleaning carried out without the need for you to intervene thus maintaining the boiler’s performance at maximum efficiency. All of the ash produced collects in an easily removable ash box with keeping your hands clean.
* Ash box is equipped as standard or option depending on the models.

4. Flexible and economical

When demand for heat is high it will switch to maximum output. But when demand tails off it will adjust its output accordingly- to as low as 30 % of its availabile capacity, keeping fuel use to a minimum.

5. High energy efficiency at low load

Thanks to Cascade control up to four boilers can run in parallel, generating high levels of heat and low level of wear on the individual boilers. When full power is not required, only the boilers that are actually needed will be called into use.
