Autoterm 2D Diesel Heater with Single Marine Outlet Kit 12V

Engineered for life at sea, the Autoterm 2D Diesel Heater with Single Marine Outlet Kit delivers fast, reliable warmth to boats and yachts up to 48 ft / 15 m. Built to withstand salt air, temperature swings, and the vibration of moving water, this marine-grade heater keeps living spaces comfortable when weather conditions turn harsh.

Powerful yet adaptable, the Autoterm 2D offers a two-stage heat range: 2.0 kW for rapid heat-up and 0.8 kW for steady, energy-efficient comfort during longer passages or overnight rests. With an impressive airflow of up to 86 m³/h at high power and 34 m³/h at low power, you’ll enjoy even heat distribution across cabins, saloons, and wheelhouses, so no corner goes chilly.

Fuel efficiency matters on extended voyages. The heater uses approximately 0.24 L/h at maximum output, helping you manage fuel more effectively without sacrificing warmth. A brushless induction motor minimizes noise and extends service life in challenging marine environments, so you can enjoy quiet heat even when your engines are off.

Compact, Marine-Grade Design

The Autoterm 2D is compact and lightweight—about 2.9 kg with dimensions of 400 × 360 × 170 mm—making installation in tight engine rooms or lockers straightforward. The Single Marine Outlet Kit provides a ready-made, marine-appropriate path for heated air, featuring an exhaust and air intake setup designed to keep interior air clean and well-distributed.
