AUTOTERM Air 2D – 2 kW heater kit with installation kit

Item no. AUT-10010

Make cool evenings on board more comfortable with compact, fixed-installation heating.

  • Heat without a shore-power connection: the heater uses diesel and a 12 or 24 V supply.
  • Choose a controller to suit your use. Comfort Control offers thermostat control and timers when selected.
  • Access manufacturer manuals and spare-parts information for installation and later servicing.

The 0.8–2.0 kW range must match the actual heat demand. Boat length alone is not enough.

How to use the size guidance

This is SejlStrøm’s indicative first choice for normal insulation, not a manufacturer guarantee or a calculation for year-round use. The area is the interior space to be heated. Boat length is only a rough selection guide and cannot be converted directly into m². For frost, large glazed areas, several cabins or year-round living, I calculate the requirements for the specific installation.

Size the heater according to heat loss, insulation and air distribution. A particular length in feet or area in m² does not guarantee sufficient heating.

Check compatibility and limitations

Check model, voltage and variant before ordering.

Selected, documented parts for this heater model. Accessories are optional; spare parts are for servicing. Check the package contents before buying additional parts.

The accessories list is a selection of compatible options, not a complete installation list. Brackets and housings are different mounting options; buy only the solution that suits the installation. Always check the package contents. Spare parts are for servicing.

This product has both Standard and Tight Space variants. New housings and mounting boxes are not generally matched to all these variants; the housing version must be confirmed first.

Installation and choosing accessories

Boat length alone does not determine the required size. Follow the manual for fuel, power, combustion air and a gas-tight exhaust routed outside.

🔧 Installation and compatibility

Size and route the power supply, fuel system, exhaust, combustion air and warm-air ducting in accordance with AUTOTERM’s manual. Marine installations require particular attention to through-hull fittings, exhaust slope, condensation and a safe distance from combustible materials.

💡 My advice before ordering

I recommend choosing the model according to the actual heat loss and the available installation space, rather than maximum output alone. Send the boat type, length, insulation details and a couple of photos of the installation area, and I will help you choose the right variant and the accessories you need.

Accessories compatible with AUTOTERM Air 2D

Selected, optional accessories. Check the contents of your selected variant and the requirements of your installation before ordering extra parts. This list is not a complete bill of materials for every boat or camper.

Spare parts for AUTOTERM Air 2D

For servicing and replacement – not mandatory extras for a new heater. This is a checked selection. Individual parts may already be included in a gasket set, so check before buying them all together.

If the heater develops a fault, I can help identify the spare part using the model, serial number and symptoms. Parts restricted to particular serial numbers are not included as general extras.

Full product description

Select voltage and control panel

The kit includes the heater and standard installation parts. If you choose "Without panel," a control panel is not included. A compatible panel is required to operate the heater. If you choose a panel variant, the selected panel is included.

Hot air ducts, vents, and boat-specific installation parts are chosen based on the installation. See control panels and marine installation kits for Air 2D and Air 4D.

Quick selection – is this right for you?

Choose this if you want: a complete AUTOTERM Air 2D base solution for fixed installation and prefer documentation, spare parts, and a proven system.

  • Type: complete heater kit for fixed installation
  • Output: 2 kW class
  • Voltage: select 12 or 24 V variant
  • Good for: smaller boat, camper, or rooms with moderate heating needs

Before ordering: select the correct voltage and panel variant. Boat-specific hot air distribution, hull fittings, and other installation parts may still depend on your specific boat.
