Delivering warmth inside a marquee during winter is one of the most demanding challenges in temporary event infrastructure. Heat loss, fluctuating external temperatures and the need for safe operation in occupied spaces all place significant pressure on heating systems. For large-scale events, poor heating doesn’t just affect comfort; it also impacts dwell time, guest satisfaction and commercial performance.

After an incoming call from the client, the Andrews Heat For Hire team developed a bespoke temporary event heating solution that combined technical performance with discreet design to create a warm, welcoming environment throughout the event.
Why Temporary Event Heating Requires a Specialist Approach
Temporary event heating in London presents unique challenges, particularly during winter. Marquees are typically constructed from lightweight materials with limited insulation, making them highly susceptible to heat loss. High footfall, frequent door openings and extended operating hours further complicate temperature control.

Key challenges our dedicated engineers were required to overcome included:
- Maintaining consistent internal temperatures in large, open-plan spaces
- Ensuring heating systems are safe for use in occupied environments
- Avoiding visible or intrusive equipment that detracts from event design
- Delivering reliable performance throughout long daily operating periods
Conventional direct-fired heaters or poorly distributed airflow risk creating cold spots, uneven temperatures and visual disruption, all unacceptable for a high-profile event environment.
Comfort Without Compromise
The client needed a marquee heating solution that could reliably warm hundreds of daily visitors. The system also had to blend seamlessly with a dark, premium interior aesthetic. It needed to be powerful, efficient and discreet, keeping guests comfortable without drawing attention to the infrastructure. To meet the brief, Andrews Heat For Hire experts specified the Aurora FH 185 DV indirect oil-fired heater, paired with black perforated ducting, to deliver a tailored solution designed specifically for large winter marquees.


Our team selected this heater for its ability to deliver consistent, high-volume heat, making it ideal for maintaining stable temperatures inside a large marquee despite cold external conditions.

Installation, Operation and Performance
The team installed the heating system efficiently, causing minimal disruption to the event build schedule. Once operational, it delivered immediate warmth, allowing internal temperatures to stabilise quickly.
The bespoke marquee heating solution exceeded expectations, delivering both performance and visual integration. Guests and staff benefited from a warm, comfortable environment, while the heating infrastructure remained largely unnoticed, which is a key success factor for premium events.
The client was highly satisfied with the outcome and has since requested that Andrews Heat For Hire re-deliver the same temporary heating solution for their annual winter event.
