Designed for large commercial saunas.
The Narvi Ultra Big large commercial electric sauna heater is ideal electric heaters for large commercial saunas fitted in gyms, spas, hotels and wellness retreats. These heaters can also be fitted in large personal or group saunas. They are the perfect choice for demanding usage requirements, such as being active all day, every day. The Ultra Big is a truly unique, one-of-a-kind commercial heater. No other sauna heater on the market combines the authentic Finnish sauna experience that comes with such a large stone capacity, with such an outstanding build quality and durability. When it comes to heating large authentic commercial saunas, there is no better option that the Narvi Ultra Big.
The Ultra Big is a larger version of the Narvi Ultra and similarly is stainless steel inside and out, with some of the highest material thicknesses on the market. The elements have a market leading thickness and grade, making this the ideal heater for frequent use where water can and should be poured over the stones.
It is certainly true that there are sauna heaters and there are sauna heaters. This is also very much the case for commercial heaters. Most modern hidden/behind-the-bench heaters and commercial heaters simply act as a heater with no stones. This creates an unpleasant löyly and is nothing like the very relaxing and enjoyable experience of authentic Finnish sauna. Sadly however, this is the experience that many of the British public attribute to sauna from their brief encounter with their local health club. This heater will set your sauna apart from the competition by being one of the few truly authentic Finnish electric sauna heaters in the U.K.
The Ultra Big series combines Narvi's renowned build quality and longevity with their market leading stone capacity to provide a commercial heater that is simply like no other on the market. Show your customers what it means to relax and enjoy a true Finnish sauna, with a genuine Finish-made, Finnish-designed commercial sauna heater.
