A true miracle of space

The new Neo-MHV 1/2 & 1 meter log heating

As a biomass pioneer, Hargassner researches and develops the future of heating with a keen sense of the environment. These innovations make the boilers some of the best biomass heating solutions available in the world today. The Neo-MHV gives wood log boilers with higher heating requirements the freedom to choose: with two log lengths, there are twice as many options for reliable heat. Despite its extremely large filling chamber, it is still a real space saver. Sophisticated technology and controls make it possible to realise small outputs despite the use of 1 metre logs. The ideal areas of application for the new Neo-MHV are single- and multi-family houses as well as agriculture and forestry.
