Managing the temperature in a marquee or outdoor event space is a technical requirement rather than a luxury. When planning an event in the UK, the ambient temperature often drops significantly once the sun sets, even during summer months. Selecting the correct outdoor heater hire for marquee applications requires an understanding of heating capacity, fuel types, and safety regulations.
The choice between gas and electric heating depends on the power supply available at the venue and the specific structure of the marquee.
Gas heaters, typically powered by propane, are common for large marquees because they do not require a high-amperage electrical connection. They provide high heat output and are portable. However, they require strict adherence to ventilation rules. Because gas heaters consume oxygen and produce combustion by-products, they must never be used in completely sealed environments. Marquees must have sufficient air exchange to prevent carbon monoxide build-up.
Electric heaters are suitable for smaller, enclosed spaces or areas where gas is prohibited by venue policy. They provide clean heat without fumes. The primary limitation is the power draw; a large marquee may require multiple circuits to support several high-wattage electric heaters without tripping the venue's breakers. Always check the total load against the venue's power supply before booking.
Heating capacity is measured in kilowatts (kW). As a general rule, you need approximately 100 watts of heat per square metre for a standard marquee. This figure increases if the marquee has poor insulation or if the outside temperature is particularly low.
When calculating requirements, consider the heat loss through the marquee walls and roof. A heavy-duty PVC marquee retains heat better than a lightweight pop-up structure.
For a standard 20m x 10m marquee (200 square metres), the heating requirement is significant. Below is a guide for estimating the number of units required based on a standard 12kW output per gas heater.
| Marquee Size | Area (sq m) | Est. Heat Required (kW) | Units Required (12kW units) |
|---|---|---|---|
| 6m x 6m | 36 | 3.6 | 1 |
| 10m x 10m | 100 | 10 | 1 |
| 20m x 10m | 200 | 20 | 2-3 |
| 30m x 15m | 450 | 45 | 4-5 |
Safety is the priority when using heating equipment. Improper placement is a fire hazard and a risk to guests.
Every heater has a minimum clearance distance from combustible materials. This includes marquee linings, curtains, decorations, and tables or chairs. For gas patio heaters, maintain a minimum of 1 metre of clearance from the top of the heater to the marquee roof and at least 0.5 metres from the sides. If you are using glassware or other items nearby, ensure they are not positioned where they could become hot to the touch.
If you are using gas heaters inside a marquee, the structure must be ventilated. Do not seal the marquee walls completely. If the marquee is fully enclosed, you must use electric heaters instead. Always keep a fire extinguisher nearby and ensure all staff are briefed on how to shut off the gas supply in an emergency.
Placement dictates how effective your heating setup will be. Follow these practical steps to manage the environment:
When you hire equipment, provide us with the dimensions of your marquee and the expected time of year. We can assist in calculating the total kW required for your specific site. If you are also hiring tables and chairs, we can help you plan a layout that keeps guests comfortable while maintaining the necessary safety clearances from your heating units.
