Multiple systems for
optimal fail-safety

Cascade control for multiple systems

Targeted operation with up to 6 boilers

The Eco-PK pellet boilers are the perfect solution for applications requiring medium to high heating output. By connecting between 2 to 6 boilers in a cascade , an output of up to 2 MW is possible with the Eco–PK 250-330 kW. Hargassner’s advanced heating technology, with numerous standard features, ensures maximum comfort and reliability. The intelligent control system balances operation across all connected boilers, with identical running times, which extends service life and improving operational efficiency. Today’s heating is efficient, effective, and cost-saving!
