Leenders Boxer Plus



What we think

Fast and slow Boxer Plus offers the best possible combination between fast and slow: the combustion chamber gets to operating temperature quick and the slow side stones keep their warmth extra long, well up to 60°C after 8 hours.

30 years ago the story of the Boxer Plus started with the Boxer. Back then a stove with very sophisticated technique, developed by Harrie in cooperation with the Technical University of Eindhoven. The Boxer was a quirky stove with a typical clientele, the ‘Boxer customer’. This ‘Boxer customer’ was often very critical and had a great interest in combustion technology.
