The Harmony LS has an open log store area under the door which is useful for storing that night's firewood and the logs look really nice too.
The Opus Harmony PR can be partially rotated - so you can have a better view of the flames if you move to another part of the room.
The Harmony GLS has the glass-covered door and the log store underneath - I really like the combination of the deep black finish to the door and the texture of the logs.
The Opus Harmony is a wide stove, slightly oval when viewed from above. The glass-covered door lends it a reflective deep black finish.
With its wide window and lovely oval shape it's no wonder that the Opus Harmony is popular. 7kW heat output makes the Harmony suited to a small-medium sized room.
