Bring the comfort of hot water into your wood-fired sauna experience. The Harvia Water Heater Pipe Model Steel (WP220ST) is a chimney-mounted water heater designed to sit directly on top of compatible Harvia wood-burning sauna heaters. As the fire heats the stove, smoke naturally passes through the integrated pipe running inside the water tank, efficiently transferring heat to warm up to 22 litres (5.8 gallons) of water without requiring electricity.
Constructed from durable steel and engineered for reliable everyday use, this water heater provides a practical source of hot water for washing, rinsing, or traditional sauna rituals. It is compatible with most Harvia wood-burning sauna heaters, excluding the Harvia 50 wood-burning heater.
Ideal for off-grid cabins, traditional Finnish saunas, backyard retreats, and wood-fired wellness spaces, the Pipe Model Water Heater transforms the heat already produced by your sauna into a dependable supply of warm water while maintaining Harvia's renowned quality and long-lasting performance.
