ZMH Šukoplam R – Off-Grid Log Boiler 80-90 kW (272,970 to 307,090 BTU)

ZMH Šukoplam R – Log Boiler (15–90 kW)

The Šukoplam R range consists of off-grid, natural draft hot water log boilers designed for the efficient combustion of solid lump fuels such as wood and coal. Available in outputs from 15 kW to 90 kW, these boilers are ideally suited to rural properties, agricultural buildings, workshops, and installations where electrical power is limited or unavailable.

Unlike fan-assisted systems, the Šukoplam R operates using natural chimney draft, making it a robust and dependable solution for locations requiring simple, mechanical operation without reliance on electricity. Combustion air is regulated via a mechanical draft regulator, which controls the airflow flap on the ash collection door to maintain stable combustion and consistent water temperature.

The boiler features a multi-pass heat exchange design, ensuring efficient heat transfer from combustion gases to the boiler water. The boiler body is manufactured from high-quality boiler steel, with water-cooled sections that maximise heat absorption while maintaining structural integrity under thermal load.

To reduce heat loss, the boiler is fully insulated with mineral wool, and the outer casing is protected with a durable coated steel finish. The Šukoplam R is designed for hot water production in 90/70 °C and 110/90 °C operating regimes, with a maximum operating pressure of 2.5 bar.

Safety is a key design consideration. Boiler protection is achieved through the installation of a pressure relief safety valve, while overheating protection is provided by a thermal safety heat exchanger, which automatically cools the boiler if temperature limits are exceeded.

Simple, durable, and highly reliable, the Šukoplam R log boiler range remains a proven solution for off-grid biomass heating using locally sourced solid fuels.
