Clean by Design. Warm by Nature.
A refined family of wood-burning sauna heaters for spaces where traditional fire meets a quieter, more architectural expression.
Traditional Fire. Reduced to Its Essentials.
Harvia Linear brings wood-fired sauna warmth into a clean, restrained silhouette that feels at home in both compact and contemporary spaces. The straightforward geometry lets the living flame remain the visual focus, creating a heater that feels purposeful rather than imposing. Across the family, different capacities and configurations give you room to choose the Linear that best fits the scale and rhythm of your sauna.
Harvia Linear Wood-Burning Heaters.
Explore the core Linear family for a clean, space-conscious approach to traditional wood-fired sauna. From smaller sauna rooms to more generous interiors, the collection keeps the visual language simple while letting the warmth and glow of the fire remain central.
A Heater That Lets the Room Stay Quiet.
Linear is for the sauna where every element is asked to earn its place. The upright form keeps the footprint visually controlled, while the dark exterior creates a grounded architectural presence. Instead of competing with timber, stone, glass, or landscape, the heater becomes part of the composition and lets the fire provide the movement.
Linear GreenFlame.
For buyers drawn to the minimalist Linear aesthetic who also want Harvia's GreenFlame combustion technology, these models bring the two ideas together in one wood-burning heater family.

What Does GreenFlame Mean?
GreenFlame is not a description of the color of the fire. It identifies Harvia's cleaner-combustion approach to the wood-burning fire chamber. The technology is designed to manage combustion more efficiently, reducing particulate and carbon monoxide emissions while preserving the atmosphere and ritual of a real wood fire.
Within the Linear family, GreenFlame models pair this combustion technology with the same restrained, contemporary character that defines Linear, adding a larger view of the flame and a more technology-focused approach to wood-fired heating.
Harvia reports approximately 20% lower particulate emissions and 70% lower carbon monoxide emissions from its GreenFlame fire-chamber design compared with its earlier combustion design.
Purpose-Built Linear Accessories.
Protective sheaths, floor protection, water-heating components, and compatible Linear accessories help adapt the heater to the architecture around it. They support a more considered installation while preserving the clean, restrained character that makes the Linear family distinctive.

Your Heater Needs a Proper Venting Path.
Choosing the Linear heater is only one part of planning a complete wood-burning sauna system. The heater must connect to an appropriate chimney and flue path designed for the installation around it. Explore compatible chimney and pipe components as you plan how smoke and combustion gases will travel safely from the heater to the exterior.
Do not treat the chimney as an optional accessory. Your final venting configuration depends on the heater, building structure, clearances, route to the exterior, and applicable installation requirements. Confirm the complete system with a qualified professional before installation.
