Cascade control for multiple systems
Targeted operating mode of up to 6 boilers
The pellet boilers of the Eco-PK series and Classic-Lambda are the right choice for all applications that already require a medium to higher heating output. If you connect from 2 to 6 heaters in cascade, i.e. in series, an output of up to 2 MW is even possible with the Eco–PK 250-330 kW. The sophisticated and well thought-out Hargassner heating technology with numerous extras as standard stands for maximum comfort and maximum reliability. The sophisticated control system ensures that each individual boiler has identical running times, which further increases service life and operational reliability. Efficient, effective and cost-cutting heating works like this today!
