The Autoterm 2D (formerly the Planar 2D) is a compact, highly efficient 2kW diesel air heater, widely regarded as the go-to solution for smaller vessels up to 33ft (10m). It provides a cost-effective, reliable way to maintain a dry and warm cabin environment, even in the harshest marine conditions.
Autoterm 2D: Compact and Reliable Cabin Heating
Despite its small footprint, the Autoterm 2D delivers a powerful 2kW heat output, making it ideal for sailboats, small motor cruisers, and narrowboat cabins. It is specifically designed for low fuel and power consumption, ensuring you can run the heater for extended periods without draining your battery bank or fuel reserves.
Key features of the Autoterm 2D include:
- Quiet Operation: Supplied with a “super quiet” fuel pump and an air intake silencer as standard to minimise ambient noise.
- Durability: The kit includes a high-grade 316 stainless steel mounting plate, essential for resisting corrosion in salt-air environments.
- Advanced Control: While the basic kit includes the PU-5 controller, it can be upgraded to the Autoterm Comfort Controller or a Smartphone Modem for remote activation via the Autoterm app.
Professional OFTEC-Trained Installation
To ensure safety and optimal performance, forced-draft diesel heaters must be installed with careful attention to exhaust sealing and fuel line integrity. At Marine Heating Solutions, our engineers are OFTEC-trained and specialise in Autoterm 2D marine installations. We ensure all installations are fully compliant with the Boat Safety Scheme (BSS).
Upon completion, we provide a Boat Diesel & Oil Appliance Certificate, providing peace of mind and meeting insurance requirements. For technical support and diagnostic information, you can access the official Autoterm 2D technical manuals or consult the OFTEC guidelines for liquid fuel appliances.
