Harvia Linear 22 GreenFlame ES 15.7kW: Low-Emission Wood Stove with Water Tank
The Harvia Linear 22 GreenFlame ES combines clean-burn GreenFlame combustion (approximately 70% fewer particle emissions) with an integrated water heating tank. The built-in tank captures chimney exhaust heat to produce hot water during the sauna session — passive, no additional fuel required. Hot water ready when the session ends.
Why Buy From RecovAthlete
We're an authorized Harvia dealer — not a marketplace reseller. Your warranty is valid and your order is fulfilled correctly. We confirm your chimney kit for your specific ceiling height before your order ships, so you don't receive the wrong flue components on installation day.
Questions about sizing, clearances, or installation? Call 866-861-6317 and you'll reach someone who has configured dozens of these setups.
“GreenFlame produces approximately 70% fewer fine particle emissions than a standard wood sauna stove — without any measurable reduction in löyly quality.”
Eco-conscious sauna owners who also want hot water — the GreenFlame ES gives you both low-emission combustion and passive hot water from chimney heat.
Cabin and outdoor sauna builds where a separate water heater would add complexity.

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
How does the integrated water tank work on the GreenFlame ES?
The water tank is connected to the chimney pipe and uses heat from the exhaust gases to warm water during the sauna session. By the time you finish bathing, the tank contains hot water for washing — produced with no additional fuel or energy input.
