The Arcotherm EC55 Indirect Diesel Space Heater delivers 51kW of clean, fume-free warm air, making it a popular choice for marquees, events, construction sites, workshops, and warehouses. With its ability to provide safe heating in enclosed or poorly ventilated spaces, it’s one of the UK’s most trusted marquee and site heaters.

This heater is designed for efficiency and portability. Large wheels and a sturdy handle make it easy to position outside a structure, while flexible ducting directs warm air inside exactly where it’s needed. Optional 3m or 7.6m ducting, as well as splitter kits, allow you to heat multiple areas at once.

Built tough for demanding environments, the EC55 features a stainless steel combustion chamber, automatic oil burner, Danfoss pump, electronic flame control, and robust 65L hydrocarbon-resistant fuel tank. It is dual voltage (110v/240v), giving flexibility across different sites, and includes safety features such as an overheat thermostat and electronic control panel.

The EC55 offers 12 hours of runtime per tank. Combined with available marquee heater packages, which include ducting, flue, and thermostat with free delivery, the EC55 is a reliable and cost-effective heating solution.
