The design and technique of the Boxer Plus are based on the Boxer from 1982. This gives the Boxer Plus 30 years of experience.
Everything we at Harrie Leenders know about combustion, warmth and fire, we have put into the Boxer Plus. With that, it is one of the most advanced fireplaces we have ever made.
Boxer Plus provides the ideal combination between fast and slow; the fast interior that easily reaches operating temperature and the slow sidestones that preserve the heat extra long. Until 60°C after 8 hours. (140°F)
