Installation Notes
This stove requires a chimney system running through the wall or ceiling of your sauna room. Most installations use the Harvia chimney kit — WHP1500 (stainless) or WHP1500M (black) — which is built for the standard 4.5 inches (115 mm) flue. For higher ceilings, add extension pipes WHP500 (1.64 ft) or WHP1000 (3.3 ft). A protective sheath is required if the stove is within minimum clearance distance of combustible walls. We confirm the correct chimney kit for your ceiling height before your order ships. Call 866-861-6317 for pre-installation documentation for your contractor.
On the investment: A wood-burning sauna stove built to Harvia's quality standard should last 20–30 years under regular use. Spread across years of daily sessions, the cost per use is much lower than most buyers expect. This is not a piece of equipment you replace on a schedule — it’s one you pass on.

Frequently Asked Questions
What is Harvia GreenFlame technology?
Harvia GreenFlame is an advanced combustion design that reduces fine particle emissions by approximately 70% compared to a conventional wood sauna stove. It achieves this through improved air supply and optimised combustion chamber geometry that burns wood more completely.
Does the GreenFlame Linear 22 produce less steam than a standard stove?
No. The GreenFlame technology reduces emissions, not steam output. The stove still has a full stone bed and produces authentic Finnish löyly steam when water is poured on the heated stones.
