When planning an event in a marquee, ensuring the comfort of your guests is a top priority. One of the most important aspects to consider is whether or not to use heaters to maintain a pleasant temperature inside the marquee.
The need for a heater may vary depending on the time of year, overall marquee insulation and, of course, the location of your event.
Marquee heaters can provide a warm and inviting atmosphere, but deciding on whether they are necessary depends on several factors. From mid-September to April, heating is generally recommended for marquees.
However, during the warmer months, body heat generated by attendees can help keep the marquee comfortably warm. Moreover, weather plays a significant role in this decision, and you may need to be prepared for unexpected cold snaps.
Marquee heaters come in various types, with indirect oil-fired heaters being a popular choice for temporary structures due to their ability to heat larger spaces. Ideally, you need to choose a suitable heating solution to ensure the safety and comfort of your event while keeping equipment discreetly out of sight.

Assessing the Need for Heaters in Your Marquee
Several factors, such as the season, weather, and marquee insulation, will play a crucial role in determining the need for heaters. In this section, we discuss how to make a well-informed decision on marquee heating.
Considering the Season and Weather
The time of year greatly impacts the need for heaters in your marquee. During winter, temperatures can drop significantly, making it necessary to invest in heating solutions.
However, even autumn and spring can bring chilly evenings, so be prepared – especially if your event occurs outside of the summer months.
It’s often a good best to monitor weather forecasts leading up to the event. If temperatures are predicted to be low or if there’s a chance of cold snaps, plan for heating solutions to ensure a comfortable and enjoyable atmosphere for your guests.
Understanding Marquee Insulation and Heating Retention
The insulation of your marquee will also influence the need for heaters. The ability of a marquee to retain warmth will depend on factors such as its material, construction, and insulation features – including lining and carpets. A properly insulated marquee can help maintain a more comfortable temperature with less heating.
To make an informed decision, consider the following:
- Heating Systems: When selecting a heater, be sure to choose a suitable option that does not emit fumes and is safe for indoor use. Indirect heaters with powerful fans are often the best choice, as they provide ample warmth without the risk of harmful emissions.
- Test Before the Event: It is advisable to test your chosen heating system a few days before the event, at the same time of day. This will help you gauge its effectiveness and ensure that it is sufficient for the space.
- Heating Duration: Plan to have the heating on for at least an hour before guests arrive, particularly during winter months. This will help create a warm and inviting atmosphere as they enter the marquee.

Setting Up Heaters Safely and Effectively
Installation Tips and Best Practices
When installing heaters in a marquee, it is essential to ensure that they are set up safely and effectively. Here are some best practices to follow:
Choose the right type of heater: Opt for professional grade heaters specifically designed for use in marquees or tents. These heaters often come with built-in safety features such as thermostats and temperature control.
Location: Set up the heater outside the marquee, with the heat directed inside. This will keep any fumes from the heater away from the guests and minimise any potential hazards.
Power and fuel: Ensure that the heater has access to consistent power, whether from a nearby building or a marquee generator. Keep fuel hoses and plugs away from high traffic areas to prevent accidents.
Ventilation: Make sure the marquee is well-ventilated in order to prevent the buildup of fumes or stale air.
Maintaining Optimal Temperature and Comfort Levels
To maintain a comfortable and consistent temperature inside the marquee, consider these suggestions:
Utilise a thermostat: Connect the marquee heater to a thermostat in order to automatically regulate the temperature. This will prevent overheating and ensure that guests remain comfortable throughout the event.
Monitor heating power: Adjust the heating power based on the size of the marquee and the number of guests present. A larger marquee and a higher guest count may necessitate higher heating power.
Consider insulation: Insulating the marquee will help to maintain consistent temperature levels by reducing heat loss. Opt for insulated marquee walls or lining to keep the area warm and comfortable.
Heating zones: If the marquee is divided into sections, employ separate heaters and thermostats per zone for more effective temperature control.
By following these guidelines, you can ensure that your marquee is equipped with safe and effective heating, providing a comfortable environment for all guests attending the event.
