Does this product suit your needs?

The TB10 Black suits you if you want an all-in-one toolbox heater with local control via Bluetooth. Positioning, warm-air ducting and exhaust routing need to be planned for your boat, camper or other installation. If you need to control the heater over the internet, talk to Jan about a model with that connection.

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.

What is included

  • TB10 Black Edition with built-in tank
  • Remote control and AC adapter
  • Silencer and exhaust pipe
  • Flexible warm air duct, DC battery cable and filter
  • Screws and manual

This is the standard package specified by the manufacturer. A marine through-hull fitting, exhaust insulation and a separate CO alarm must be selected to suit the boat’s installation.

Installation and choosing accessories

Use on a boat requires a properly completed installation. Combustion air and exhaust gases must be routed safely outside. The exhaust must be gas-tight, with fittings suitable for marine use, insulation and clearance from combustible materials. The heater must not stand unsecured in an occupied cabin with its exhaust inside the boat.

Size the fuel hose, pump, cables and fuse correctly. Install a separate, approved CO alarm in the living area. The boat’s insulation, interior volume and air distribution determine the heating requirement; boat length alone is not sufficient.

I do not yet have verified housing dimensions and net weight for this Black Edition. Ask me if space is critical, and I will have the dimensions confirmed before you buy.

Recommended sizing

Heated area: 11–20 m²
Boat length: 31–40 feet

This is SejlStrøm's recommended primary choice for standard 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 guide and cannot be converted directly to m². In case of frost, large glass areas, multiple cabins, or year-round living, I will calculate the specific requirements.

⚡ Practical advantages

  • Bluetooth control locally from a compatible phone/app.
  • All-in-one solution with heater unit and tank in a portable cabinet.

✅ Typically suitable for

Boats, motorhomes, campervans, vans, workshops, and off-grid installations, provided the model, power, voltage, and installation are correctly dimensioned.

⚠️ Important for boat installation

  • Combustion air intake and exhaust must be safely vented outdoors.
  • The exhaust must be gas-tight and installed using marine-grade fittings, insulation, and clearance from combustible materials.
  • Fuel line, pump, cable cross-section, and fuse must be correctly dimensioned.
  • Install a separate, approved CO alarm in the living area. A built-in CO function does not replace the boat's permanent alarm.
  • All-in-one/Toolbox models must not be left loose in an occupied cabin unless the entire combustion circuit is permanently and gas-tightly routed outside.

Always check the selected variant and Sunster's current documentation before installation.
