Strong performance at a fair price

The compact solution for wood log heating

The Smart-HV impresses with its compact size, its functionality and of course its attractive price-performance ratio. It has a filling space for ½ metre logs matched to the boiler output. The modern gasification technology comes from its exclusive brother – the Neo-HV. Its user-friendly touch display ensures convenient operation. The Smart-HV is particularly suitable for detached houses and smaller residential buildings with lower heat demand.

The Smart-HV 17–23 log boiler is also available as a wood log pellet combi boiler.
