  Product Description
The Whale Heat Air 3GT 3kW Underfloor Space Heater (Gas Only) is the smallest in the Whale Heat Air range, running solely on gas. It’s a good option for campers who prefer off-grid heating or travel with limited access to electric hook-up.

Designed for vans and smaller motorhomes, the 3GT saves indoor space by mounting under the floor. It delivers quick, even heating throughout the interior, keeping you warm without bulky heaters or vents taking up wall or cupboard space.

Whale’s 3GT 3kW heater is the smallest model in the Heat Air range and runs entirely on gas. It’s a solid option for compact campervans and panel van conversions where saving space and weight is essential. Mounted underfloor, the unit keeps your interior free of visible heating units, allowing for longer beds, larger storage areas, and more flexible layout choices.

This gas-only model suits off-grid setups or vans that spend time away from mains hook-ups. The 3kW output provides fast and even heat distribution throughout your vehicle. With underfloor ducting, warm air circulates from the ground up, giving a more natural and efficient way to heat the living space.

Despite its simplicity, the 3GT is equipped with modulating controls, meaning it automatically adjusts the output based on your set temperature. This helps reduce gas usage while keeping conditions consistent inside the van. It's also extremely quiet during operation, making it suitable for night use without disturbance.

Best for
  • Off-grid or wild campers
  • Compact campervans and panel van conversions
  • Installers prioritising simplicity and weight-saving
