Jefferson Tools JEFHTIND240 240000 BTU Indirect Oil Heater 230V

Designed for professional environments where heat quality and safety are just as important as output, the Jefferson Tools JEFHTIND240 240,000 BTU Indirect Oil Heater 230V delivers powerful, clean hot air for large indoor spaces without introducing combustion fumes into the working area. With its indirect heating design and integrated heat exchanger, it is ideal for locations where people are working continuously and air quality must be controlled.

Producing an impressive 58.1kW of heating power, this indirect oil heater is capable of warming areas of up to 340m², making it well suited to large workshops, warehouses, marquees, event structures, and commercial buildings. The indirect system separates combustion gases from the heated air stream, while flue gases are safely expelled through an external exhaust, allowing the heater to be used in enclosed or semi-enclosed environments when installed correctly.

Built for extended operation, the JEFHTIND240 features a large 80-litre fuel tank, combined with a maximum fuel consumption of 5.7 litres per hour, delivering up to 14 hours of runtime on a single fill. This makes it a practical solution for long shifts, overnight heating, and situations where uninterrupted warmth is essential.

Advanced control and safety systems

This heater is engineered with multiple layers of protection to support safe, dependable operation in demanding conditions. An overheat thermostat and thermally protected motor guard against excessive temperatures, while electronic flame control with photocell monitoring ensures stable combustion. A diagnostic LED provides quick visual feedback, helping identify faults promptly, and post-ventilation allows the system to cool down safely after use.

Built for mobility and serviceability

Despite its high output, the heater is designed to move easily between sites. A built-in trolley system allows smooth manoeuvring across warehouses, yards, and event locations. Maintenance is simplified with an accessible fuel pump, an oil pump filter, and an external suction filter with a transparent glass cup, enabling quick inspection and servicing. The stainless steel combustion chamber adds durability and long-term resistance to heat and corrosion.
