Rinnai UK supply 1600e Continuous Flow Gas Water Heater which exceeds hot water demands of a busy popular baking show’s tent.
Client Information
The well-known television series sees contestants compete in a number of baking challenges. The series takes place in a large marquee style tent so required an externally mounted hot water system. The contestants and crew require a reliable and consistent supply of hot water for wash stations, food preparation sinks, cleaning, and handwashing facilities throughout full days of filming.
Problem
Much like other filming productions, this is a temporary set but it must perform like a permanent installation. The set requires water supply with temperature control and consistent adequate pressure. A drawback of a busy production set is tanked hot water systems that suffer heat loss, inefficiency, and limits in capacity.
Solution
To meet these demanding requirements, production engineers chose Rinnai’s external 1600e Continuous Flow Gas Water Heater to supply hot water on demand directly to sinks and stations in the tent.
The Rinnai 1600e is an external condensing continuous-flow water heater that delivers up to ~37 L/min of hot water with precise ±1 °C temperature control. It is designed for flexible installation outdoors — perfect for tent grounds where internal plant space is limited.

Rinnai 1600e External N Series Hot Water Heater
-
- 58.4 kW output with condensing technology (high efficiency)
- Low-NOx emissions (<20 ppm) for environmental compliance
- Stainless steel heat exchanger with a long service life
- Flexible installation with long flue runs up to 46 m.
- Compact and ultra-quiet operation (~52 dB(A)) suitable for noise-sensitive environments such as a TV production set.
The unit was positioned outside the tent on a raised platform to use the limited space and was connected to a temporary natural gas supply flexible enough for field use. Primary hot water lines routed from the unit underneath the tent platform to wash and prep stations. Controls were set to deliver water at regulated 45–55 °C for handwashing and prep tasks, reducing risk of scalding and supporting food-safety protocols. Temperature-accurate delivery ensured consistent hot water exactly where needed which is crucial for hygiene and regulatory compliance on set.
Results and Benefits
Constant, On-Demand Hot Water
Rinnai’s 1600e produces heat only when water is needed which saves energy and prevents heat loss between uses. This is opposed to using a traditional tank storage system which pre-heats and stores a fixed volume, this risks shortages during peak periods.
The 1600e ensures a continuous supply of hot water during the busy filming schedule, meeting fluctuating demand without running out or dipping in temperature.
Energy Efficiency and Environmental Performance
The 1600e is a condensing water heater which extracts maximum heat from fuel, reducing operational costs compared to non-condensing heaters or tank systems.
Low-NOx technology supports environmental objectives, especially important for broadcast production sustainability goals.
Space-Saving and Quiet Operation
The compact external unit requires minimal plant space — critical for a tent with limited engineering footprint. With noise levels suitable for production environments, the unit operates without interfering with filming audio.
Scalable Design
If demand were to increase (e.g., adding more washing/handwashing stations for a larger series or additional crew), additional Rinnai units can be cascaded together to provide even greater hot water capacity.
Conclusion
The installation of the Rinnai 1600e external continuous flow heater provided reliable hot water delivery on demand, lower operational cost, and higher energy efficiency. It enhanced hygiene and safety for food prep and handwashing areas. The installations flexibility suited to a temporary but demanding environment.
This solution demonstrates how commercial continuous flow hot water systems — typically used in hospitality and process industries — can be effectively applied to event catering and TV production environments such as this, where hot water reliability directly supports operational success.
