Steel Boilers / OPOP H4EKO Series

The H4EKO steel solid fuel boilers in manual mode are designed for firing with firewood, wood chip briquettes and coal, or in automatic mode using wood pellets with a diameter of 6–8 mm. A pellet burner will need to be connected. When choosing firewood, wood chip briquettes or coal as fuel, the pellet burner must be dismantled. The output range of H4EKO steel boilers is from 12 to 50 kW in manual mode and 2–24 kW in automatic mode using wood pellets.
