WHALE:
SAVE
SPACE

Engineering excellence from Northern Ireland. Whale specializes in underslung water and air heating that clears your cupboards and simplifies your internal build.

The Space-Saving Authority

Whale has revolutionized the campervan market with its range of **underslung appliances**. By mounting the bulk of the heating hardware beneath the vehicle chassis, Whale allows van builders to maximize their internal storage space.

For MWB and SWB vans where every square inch counts, a Whale system is often the difference between having a full-size wardrobe and having to sacrifice storage for a large internal heater.

Expanse Water Heater

Internal Space, External Heat

The Expanse is a 8-litre water heater that mounts under your van. Running on both gas and electric (230V), it provides rapid heat-up times and features a robust frost-protection system essential for UK winters.

Heat Air Systems

Gas & Electric

The Heat Air G/E provides powerful 2kW air heating using either LPG or 230V mains hookup. This versatility is perfect for both off-grid wild camping and campsite use.

Quiet Night Mode

Whale's advanced control logic includes a dedicated night mode that reduces fan speed to a whisper while maintaining a constant cabin temperature.

The Underslung Advantage

By moving the 'wet' and 'gas' components outside the vehicle, you not only save space but also significantly reduce the risk of internal leaks and condensation. Whale's mounting kits are specifically designed for the rigors of the road, featuring corrosion-resistant materials and waterproof connectors.

The Whale Advantage
