EVOPELL PLUS – The compact design of the Evopell Plus boiler makes it an excellent choice especially for buildings with a small boiler room, where efficient use of space is essential. The enlarged pellet hopper doubles the operating time on a single fuel load compared to the Evopell boiler.
Dear Customers,
we would like to remind you that the high-standard wood pellet boilers manufactured by our company are not equipped with an emergency (auxiliary) grate or an ignition chamber, nor are they designed for the installation of components enabling combustion outside the automatic burner.
Only fuels specified by the Manufacturer in the Boiler User Manual may be used.
Any modifications made to adapt the boiler for burning fuel outside the automatic combustion chamber are illegal, void the warranty, and may pose a danger to the health and life of the user.
