Pellet boiler

PE1 Pellet

Occupying just 0.38 m² of space, the PE1 Pellet boiler sets new standards. The new PE1 Pellet stands out for its quiet operation and ease of use, combined with low emissions and very low energy consumption. Thanks to its high energy efficiency the PE1 Pellet is particularly suitable for low-energy and passive houses.

The compact solution for the boiler room

A unique design: The new PE1 Pellet is optionally available with DHW tank block for hot water and hydraulic block with heating circuit pumps, heating circuit mixing valve and DHW tank loading. These two modules make the PE1 Pellet the compact all-round solution for the boiler room.
