About this range

Find the right diesel heater without being a technician

I have collected the models I would most often point to first. Start with size, installation, and how you want to control the heater.

Safe shopping at SejlStrøm: 2-year warranty, Danish service and support, and a 30-day right of withdrawal.

Your need Start here
Smaller boat / smaller space Sunster SH B2 2 kW or AUTOTERM Air 2D
Medium-sized boat / permanent installation Nordkapp 5 kW or AUTOTERM Air 4D
8 kW permanent installation with WiFi/Bluetooth Sunster SH W8
Affordable toolbox with Bluetooth Sunster TB10 Black
Toolbox with WiFi + Bluetooth Sunster TB10 WiFi
Toolbox with GSM/LTE remote control Sunster HTB1 GSM/LTE

How to choose

  • 2 kW: typically for smaller spaces and smaller boats when installation and heat loss are suitable.
  • 4–5 kW: typically for larger spaces or higher heat loss.
  • 8 kW: choose based on actual heating needs – a higher number is not automatically better.
  • Toolbox: easy all-in-one solution, but combustion air and exhaust must still be led safely to the outside when used on a boat.

Are you in doubt? Send the boat type, length, voltage (12/24 V), insulation, and preferably a picture of the mounting area. Then I will help you choose the right one.

Feet and m² are indicative. Year-round use, frost, large glass areas, and multiple cabins may require a specific calculation.
