Guide to Heating a Marquee
This guide explains when marquee heating is needed, how it is used, and what to plan for in advance.
It is intended to help you maintain a comfortable environment during cooler weather or evening events.
When marquee heating is required
Heating is commonly used for events held during autumn, winter, and early spring, as well as for evening events where temperatures drop after sunset.
Even in milder months, heating may be necessary if sidewalls are fully enclosed or if the event runs late into the evening.
If guests will be seated for long periods, such as during a meal or speeches, heating is more important than for short, standing-only events.
Types of marquee heating
We supply Marquee Heating suitable for temporary event use.
These heaters are designed to provide steady warmth within an enclosed marquee when used correctly.
Heating performance depends on marquee size, weather conditions, and how enclosed the structure is.
Fully enclosed marquees retain heat more effectively than partially open setups.
Power requirements
Marquee heaters require a suitable power supply.
Before booking, you should confirm that a power source is available at the event location.
Extension leads and power distribution should be planned in advance.
For guidance on safe power usage, refer to the Guide to Power and Electrics for Marquees.
Heater placement and safety
Heaters must be positioned safely within the marquee and kept clear of furniture, fabrics, and walkways.
They should not be placed where guests can accidentally touch or obstruct them.
Once installed, heaters should not be moved or adjusted.
This helps ensure consistent performance and reduces safety risks.
Reducing heat loss
To make heating more effective, sidewalls should remain in place during colder conditions.
Frequent opening of entrances allows warm air to escape and reduces overall comfort.
Planning clear entry and exit points helps limit heat loss.
See the Furniture Layout Guide for Marquees for layout considerations that support this.
Choosing the right marquee size
Heating works best when the marquee size matches the guest numbers and layout.
Oversized marquees with small guest numbers can feel colder, while overcrowded marquees restrict airflow and comfort.
The Marquee Size Guide can help you select a size that balances space and warmth.
Heating for weddings and formal events
Weddings and formal events often involve seated dining and longer event durations.
In these cases, heating is strongly recommended during cooler months.
Our Wedding Marquee Hire setups commonly include heating as part of the overall planning.
You may also wish to review Marquee Packages when comparing options.
Final checks before your event
- Confirm power availability at the site
- Ensure the marquee will be fully enclosed if heating is required
- Allow clear space around heaters
- Plan controlled entry points to reduce heat loss
