This item is not tied to a specific heater or stove model — it suits any Harvia sauna.
- A flue-mounted water tank heats wash water off the same fire that heats the room.
- Never fire the stove with the tank empty.
- Confirm the tank matches your stove and flue arrangement before ordering.
Can the water tank be fired empty?
Never. Always fill the tank before lighting the stove. Firing it dry will damage it and can be dangerous.
Does this heat water without electricity?
Yes. The tank is heated by the flue of the wood stove, so the same fire that heats the room heats the wash water — which is the point in an off-grid or cottage sauna.
