Lightweight and compact blown air heating systems

Whale Product Badge

The new lightweight, powerful, space creating gas and electric heating solution for the RV market.

Suitable for caravans, motorhomes and camper vans, and available in 2 power options, 5 GE and 6 GE, Heat Air is the versatile heating solution capable of running on gas and electric for maximum output, electric only when on site, or gas only when wild camping.

Like all Whale heating products, Heat Air is designed to be installed underfloor, opening valuable internal living and storage space. This not only saves space but gives manufacturers freedom to think outside the box. Consumers benefit from increased bunk space, full length wardrobes and longer beds.

Weighing only 8.7kg with a compact and rotatable design, Heat Air is designed to help adventurers enjoy their freedom anytime, anywhere with total comfort day and night.

  • Fast heat up and fully automatic output modulation for enhanced user comfort
  • Quiet night time operation for when you need it most
  • Cosy van all year round
  • Even and well-maintained heat distribution
  • Easy to use, no fuss controls
  • Benefit from money saving whilst on site by using the efficient 3kW electric setting - Whale's highest electric option to date

Heat Air Gas and Electric models are fitted on selected ElddisCompassAutosleepers and Auto Trial models. For van convertors the Gas & Electric models plus the Gas Only models are available from Nova Leisure, Pennine Leisure Supplies and Propex Heatsource.

All Whale Space Heaters must be installed and serviced by a fully qualified gas engineer in accordance with the appropriate installation instructions and BS EN 1949-2011.

All work must be carried out by a competent person as defined by BS7671 PART2.

Please note: if incorrectly installed a risk of electrocution exists.
