High-Capacity Heating for Large Marquees and Event Structures

The Large Ductable Electric Marquee Heater Package (3 Phase) delivers powerful, fume-free heating for large marquees, event venues and temporary indoor structures. Ideal where diesel or gas heaters are unsuitable, the system provides 100% clean warm air for enclosed environments.

Exceptional 21–42kW Electric Heat Output

At the core of this package is the Broughton FF42 Ductable Electric Heater, offering adjustable heat outputs of 21kW or 42kW. With a high 4000m³/h airflow, it is built to heat large areas quickly and efficiently—even in challenging weather conditions.

Direct Warm Air Distribution

Supplied with 10 metres of flexible ducting, the FF42 allows warm air to be delivered directly into the marquee or working area while the heater remains positioned safely outside. Its 500mm duct compatibility means warm air can be directed precisely where it’s needed.

Industrial-Grade Build Quality

The FF42 is engineered for demanding applications, featuring a robust steel frame, strong castors and integrated lifting brackets. Overheat protection and phase protection systems ensure reliable and safe operation on busy sites.

Ventilation and Multi-Mode Operation

The heater includes a fan-only mode for air movement during warmer conditions, alongside variable heating modes that give control over energy consumption and comfort levels throughout events or work periods.

A Complete Large-Scale Heating Package

This package includes the Broughton FF42 heater and 10m of ducting, providing a complete plug-and-heat solution for large marquees, industrial spaces and temporary indoor structures.
