The Narvi 30-litre stainless steel water tank heats water by means of residual heat from the sauna heater. The tank is installed in such a way that the heating efficiency and space requirement of the sauna heater is not affected. The tank can be easily oriented to left or right of the heater chimney flue. The tank is delivered as a separate packaged component. The support pipe, which comes included in the package, is installed between the sauna heater and the water tank, thus positioning the tank above the heater stones as shown in the picture. The water tank fits all NARVI sauna heaters with the exception of the NARVI 30 and SteamMaster models.
