The features of the 23Di fit like knocked out to most of Finland's boat fleet.

The Safire 23Di is the "big brother" of the most purchased Safire 2100D heater. Its features fit like knocked out to most of Finland's boat fleet. It’s compact, quiet and low-power, like all other Safire heaters. It is suitable for even small boats due to its size, but great for 6-8m motorboats and even 8-9m sailboats in terms of power.  

Its connections and shape are also ideal for replacing an old kerosene heater with a modern diesel heater. No wonder the Safire 2100D was already very popular. A new feature in the 23Di is, for example, completely redesigned control electronics, which also allows remote operation of the heater with the Safire 1287B remote starter.

  • Widest power range 0.7-2.3 kW and minimum power consumption 0.3-0.8 A / 3.6-9.6 W

  • Carbon brushless fan motors, very long life and quiet, smooth running sound

  • Self-diagnostics determines the cause of the malfunction and is easily reset

  • The electronic thermostat automatically controls the required heat output steplessly

  • Intelligent motor control based on PWM switch technology.

  • Easy to use and install as well as inexpensive to maintain, even by yourself.

  • Very small size, only about an A4 sheet
