Olbia is designed to keep your house warm 24/7 whilst maintaining a clean burn even when shut down. Easy to operate with Haas + Sohn’s patented “Easy Control” operating system, the heater produces warm air almost immediately after lighting. The optional magnesite heat bank is the latest in heat bank technology. The stones provide the longest in heat retention even after the fire has gone out making the need to burn overnight in many cases unnecessary, therefore saving even more on fire wood.
