About this range

Diesel heater, diesel furnace, Chinese heater and boat heater are terms often used for compact diesel-powered heating solutions. Here, you will find both 12 V and 24 V models for boats, as well as solutions also used in campers, caravans, vans, and workshops. The range includes air heaters, water-based diesel heaters, toolbox/all-in-one models, and installation parts.

Choose a diesel heater in under a minute

You don't need to know all the models. Start with the three things that determine your choice: how much needs to be heated, whether you want a fixed installation or a toolbox, and whether the system is 12 or 24 V.

Just want a secure way to buy?

  1. Choose 12 or 24 V according to your electrical system.
  2. Choose heating capacity based on the space that actually needs to be heated – not just the boat's length.
  3. Choose fixed installation or a toolbox.
  4. Check what is included in the package.
  5. For boats: plan exhaust, fuel, power, hot air, and a separate CO alarm as one combined installation.

I'm still in doubt – what should I send to SejlStrøm?

Send the boat type, length, approximate heated area, 12/24 V, whether the boat is used in winter, and preferably a photo of the installation area. Then I can help you choose a model and necessary accessories.

Feet and m² are indicative sorting aids. Year-round use, frost, large glass areas, poor insulation, and multiple cabins can change the requirements significantly.
