Product Description

Powerful Wood Sauna Heating with Integrated Hot Water Convenience

The Harvia Pro 20 ES WKPR20ESM wood-burning sauna heater combines strong heating performance with the added practicality of a built-in front water tank. Designed as a popular solution for cottage and off-grid sauna environments, this heater heats both the sauna and water simultaneously for a more efficient and convenient sauna experience.

Equipped with an integrated front-mounted water tank, the Pro 20 ES uses stove heat to warm water while generating rich and consistent sauna heat.

Fire, stone and the setup around them Have a wood-heater question? Ask away. We can help you understand the product before you build around it.

A wood-burning heater involves more than choosing a stove. Chimney routing, room volume, clearances, stones, protective surfaces and the surrounding sauna design all matter. If one part of the setup is unclear, send us the question before ordering.

You can ask us things like...

Harvia product: Harvia PRO 20 Wood Burning Heater | 30L Front Water Tank | WKPR20ESM
Chimney design, combustion clearances, floor and wall protection, local building requirements and final installation should always be confirmed against the manufacturer documentation and with the appropriate qualified local professional. Between Living can help identify the relevant Harvia specifications and product documents before that conversation.
Your email app will open with the product and your question already prepared. Add room measurements, photos or a sketch of the proposed chimney route if useful, then press send.
