Marquee Heaters -Indirect Fired Heaters

Marquee Heaters “M Series” Oil or Gas Fired Mobile Indirect Heaters Output from – 22kW to 173kW

These Marquee Heaters are indirect marquee heaters – These reliable and efficient marquee heaters are ideally suited in places where there is limited ventilation, as they can deliver high volumes of clean, dry, fume free warm air heat safely and economically for any outdoor events or temporary heating requirements.

These space heaters are especially suitable for marquees and outdoor events as they can be positioned outside with a warm air hose connected, delivering the hot air heat to inside via flexible ducting to keep the guests warm at the desired temperature.

These indirect oil or gas fired mobile space heaters are also ideal for temporary heating of  exhibition halls, workshops, warehouses, construction sites, industrial environments, in fact virtually anywhere you need to keep warm, quickly and efficiently for the heating requirement.

The warm air is blown out of the front of the heater and is carried into the space via flexible ducting. A flue system exhausts gases created during combustion from the top of the heater and into the atmosphere, ensuring that the warm air is entirely free of contaminants and safe.

 A remote thermostat allows you to set and change the desired temperature as needed. The ideal solution for a comfortable environment.

The fuel supply from the inbuilt oil tank ( on the model 25 and Model 50 and an option on the 70 Model of oil indirect heaters) is done via an integrated high-pressure pump with the MA models. Furthermore, the M series of marquees heaters or oil indirect heaters are equipped with a preheated oil filter and a room thermostat connection so they can be thermostatically controlled and are used with a flexible ducting warm air hose for fume free warm air from the outdoor heater into the enclosed spaces.

MARQUEE HEATERS – INDIRECT OIL FIRED HEATERS – WORKING FEATURES

These marquee heaters / indirect oil heaters can be used in three operating modes –

1. Ventilation Only Mode – Whereby the heater will run with the burner switched off, and just blow the ambient air around the marquee
2. Heating without room thermostat – The warm air heater will run with the oil burner firing until manually switched off
3. Heating with room thermostat – The warm air oil heater will be controlled via room stat (an optional accessories that we sell) and this controls the heater operation purely based on the temperature you require -thus thermostatically controlled indirect heaters.
