Air heaters for boats
Our Air-Top models heat the air directly with a heating output of between 2 and 5.5 kW and blow it into the cabin at individually definable outlet points. To implement the ideal installation solution for the heater, the air outlets, the fresh air intake and the exhaust air, Webasto offers a wide range of stainless steel accessories. You can also combine two heaters if your heating requirements are greater. Webasto air heaters are extremely efficient and quiet. Thanks to their compact size, they do not take up much space on board. For operation, you can choose between the easy-to-understand, central MultiControl or the ThermoConnect app, which can be controlled from anywhere.

Water heaters for boats
Our water heaters come invarious sizes, from 5 to 120 kW heat output. They heat the water in a radiator system, which then heats the air in the various areas on board. It is also possible to integrate a boiler into the circuit to heat water. The advantages of water heating are very even heat and the option of preheating the engine. Some appliances can be integrated into a complete A/C system.

Heating solutions for e-boats
For battery electric boats, Webasto offers extremely efficient high-voltage heaters (HVH) with heating outputs between 5 and 12 kW. With their clever stratified heating technology, the HVHs convert direct current into heat with virtually no loss. All models are ISO 21434-compliant, but differ in terms of voltage, communication interfaces and service life. Thanks to their extremely compact design, the HVHs require very little installation space. They can heat both the cabin and the drive batteries, thus increasing their service life and range.
