Jefferson Tools JEFHTIND170 170000 BTU Indirect Oil Heater 230V

Large indoor spaces demand heating that is powerful, safe, and suitable for continuous use. The Jefferson JEFHTIND170 170,000 BTU Indirect Oil Heater 230V is engineered to meet those demands, providing clean hot air through an indirect heating system that separates combustion gases from the warm air supply.

With a heat output of 41.7kW, this heater is capable of warming areas of up to 240m², making it well suited to workshops, warehouses, industrial units, event structures, and other enclosed or semi-enclosed environments. The integrated heat exchanger ensures that only clean, fume-free air is delivered to the workspace, while exhaust gases are expelled through a dedicated flue gas outlet.

Built for long-duration heating

A generous 80-litre fuel tank, combined with a maximum fuel consumption of just 4 litres per hour, allows for extended operation with fewer refuelling interruptions. This makes the JEFHTIND170 a practical solution for long workdays, overnight temperature control, and professional heating applications where downtime is not an option.

Advanced safety and control

The heater is equipped with a comprehensive range of safety features designed for industrial use. These include an overheat thermostat, thermally protected motor, and electronic flame control with photocell monitoring. A diagnostic LED provides quick visual fault indication, while post-ventilation allows the system to cool safely after shutdown.

Designed for mobility and serviceability

Despite its high output, the JEFHTIND170 is easy to move between locations thanks to its built-in trolley system, making it ideal for multi-site use. Maintenance is simplified with a fuel pump that offers easy access, an oil pump filter, and an external suction filter with a transparent glass cup for fast inspection. A stainless steel combustion chamber ensures durability and resistance to high operating temperatures, while the fuel tank level indicator allows quick fuel checks during operation.
