Straw bale boilers

Market Leaders in Biomass Heating Systems for 17 Years

Based on Danish engineering expertise, Altherm manufactures and installs its Altherm T-Series bale boilers in Hungary. These outdoor, self-contained straw-fired systems require no dedicated boiler house and are available in capacities ranging from 200–800 kW, including cascade configurations.
The technology provides a carbon-neutral heating solution. The resulting ash can be recycled into agricultural soil when mixed with liquid manure, serving as a valuable source of mineral nutrients.

The Altherm T-Series is a complete bale-fired heating center, as it integrates not only the boiler but also all essential system components:

The buffer tank
The double-walled heat-recovery chimney
The complete control system
The ventilation system

This integrated design ensures reliable, efficient, and fully automated operation for high-demand applications.
The Altherm T-Series provides a dependable renewable energy solution for agricultural, industrial, and municipal facilities, including livestock farms, horticultural operations, food processing plants, and public institutions.
