Automatic Multifuel BoilerAutomatic Multifuel Boiler

* Value for lower/upper boiler output in recommended output range, related to CO2 content of 13% and mean boiler water temperature of 60°C. Stack dimensions must be calculated in accordance with DIN 4705.

 

 Heating simply can be cheaper with automatic multifuel boilers
  • At a time of rising  fuel costs , the Kroll universal waste oil boiler, which can burn nearly all vegetable, animal, conventional and waste oil, will save you money.
  • It provides you with flexibility in choosing your perferred fuel source.
