DrewKo HYBRID is a combined boiler for wood pellets and piece wood. Thanks to the possibility of burning two fuels, the DrewKo HYBRID boiler is a great solution for uncertain times or when the User has their own wood resources, but does not limit them to working only on it. The choice of burning method is limited to changing the function on the boiler controller.

The construction of the boiler is based on the design of lower combustion devices, which is characterized by high efficiency and simple use – all inspections for cleaning the boiler are located at the front of the device.

The boiler is designed for installation in an open and closed system. The warranty for the boiler exchanger can be extended to 60 months provided that the boiler return is secured with a temperature of at least 50*C – e.g. with the HYDRO 2 hydraulic set.

A heat buffer is required for a system with a boiler. The conversion factor is approximately 42l/kW of boiler power, i.e. for a 12kW boiler the required buffer is 504l, for an 18kW boiler it is 756l and for a 24kW boiler it is 1008l. In our offer you will also find heat buffers.

The size of the pellet container (not included) can be selected depending on how long the User wants to have maintenance-free operation. Pellet containers are available in capacities of 120 liters, 220 liters, 340 liters, 600 liters, 1400 liters, 2400 liters and even 3000 liters. They can be placed on each side of the boiler, and the 2m long feeder itself can be shortened according to the needs of a given boiler room.
