Safire 23Di

A ball of fire!

Safire 23Di is the most popular Safire heater – and no wonder. Its features fits like a glove to most of Finnish boats.

It is compact, quiet and consumes little battery power – like other Safire heaters. Due to its small size it suits well even to smaller boats but because of its capacity it suits extremely well to 6-8m motor boats and even to 8-9m sail boats. Its connections and shape makes it perfect to replace the old petroleum heater with a modern diesel heater. No wonder the 23Di is so popular.
