How to use the size guidance
This is SejlStrøm’s suggested starting point for normal insulation, not a manufacturer guarantee or a calculation for year-round use. The area refers to the interior space to be heated. Boat length is only a rough way to narrow down the choice and cannot be converted directly to m². For freezing conditions, large glazed areas, multiple cabins or living aboard all year, I calculate the requirement for the specific installation.
✅ Typically suitable for
Boats, motorhomes, campervans, vans, workshops and off-grid installations, when the model, output, voltage and installation are correctly sized.

Installation and choosing accessories
Boat length alone does not determine the required size. Follow the manual for fuel, power, combustion air and gas-tight exhaust routing to the outside.
Important when installing on a boat
- Combustion air and exhaust gases must be routed safely outside.
- The exhaust must be gas-tight and use fittings suitable for marine use, insulation and clearance from combustible materials.
- The fuel hose, pump, cable cross-section and fuse must be sized correctly.
- Install a separate, approved CO alarm in the living area. A built-in CO function does not replace the boat’s fixed alarm.
- All-in-one/Toolbox models must not stand unsecured in an occupied cabin unless the entire combustion circuit is permanently routed outside and gas-tight.
Always check the selected variant and Sunster’s current documentation before installation.
