Onyx Liv 3 Gas Stove
The Onyx Liv 3 is a freestanding gas stove with a tall, cylindrical body that makes a striking contemporary centrepiece. Its sweeping curves and clean lines give it a sculptural presence, whether it stands in a fireplace recess or out in the open as the focal point of a room.
Glass panels at the front and on both sides give a 180° view of the flames, which rise tall and slow through highly realistic logs. Behind them, the mirror-polished EchoFlame™ Black Glass Lining adds depth and definition to the flame picture from every angle. With conventional and balanced flue models, the Liv 3 can be installed with or without a chimney. Contact us to find out more.
Onyx is part of the Stovax Heating Group, bringing more than 40 years of British design and engineering to each stove and fire it makes. Every Onyx model is developed in the group’s own research and development laboratories.
