The Arcotherm Jumbo 235M is engineered for one purpose: to deliver powerful, dependable heat to large enclosed areas. With an impressive 217kW of heat output, this heavy-duty indirect oil-fired heater provides 100% clean, fume-free warm air — perfect for environments where people are working indoors, or where air quality is critical.

Built for warehouses, workshops, construction sites, marquees, and event spaces, the Jumbo 235M combines rugged durability with ease of use. Its large wheels and integrated handles make transport simple, while the rear-mounted control panel ensures straightforward setup and maintenance.

Unlike standard heaters, the Jumbo range also offers a ventilation-only mode, making it ideal for drying applications such as flood restoration, crop drying, or clearing moisture from enclosed environments. The IP55-rated fan delivers efficient, quiet performance even in demanding conditions.

Accessories & Add-Ons

The Jumbo 235M can be paired with a wide range of accessories to match different site needs:

• Room Thermostat – Maintains consistent temperature and reduces fuel usage.

• Flexible Ducting – Direct warm air exactly where it’s needed, perfect for heating marquees, tents, or partitioned work areas.

• Diffusers & Splitters – Distribute heat evenly across multiple spaces or zones.

• Stainless Steel Flue Kit – Safely vents exhaust fumes outdoors, ensuring only clean air circulates inside.

Together, these accessories make the Jumbo 235M not only a heating solution, but a versatile, all-season climate control system.
