Smart-Combi - Wood log and pellets

Combi boiler system with perfect price-performance ratio

This cost-efficient Hargassner solution consists of a Smart-HV wood log boiler and a Smart-PK pellet boiler that are both filled manually. Sophisticated combustion and control technology coupled with the automatic changeover from log wood to pellets makes the smart combi additionally convenient and efficient. The heat exchanger is also cleaned manually. If the wood log boiler is empty, the system will automatically switch to pellets. This combi option can run for up to ten days without being refilled.
