The Webasto Air Top 2000 STC is widely regarded as the industry standard diesel air heater for smaller marine vessels, typically up to 35ft. Its compact design and remarkably quiet operation make it the perfect choice for creating a cosy cabin environment without sacrificing valuable on-board space.
Webasto Air Top 2000 STC: Quiet Efficiency
Engineered for reliability, the Air Top 2000 STC delivers a maximum heat output of 2kW. Its advanced fuel dosing system and silent-running fan ensure minimal fuel consumption and noise, making it ideal for overnight use. Built with high-quality components, it is specifically designed to perform in the moisture-heavy marine environment, providing consistent, dry heat to keep your cabin comfortable.
