1. A large stone capacity - To do sauna properly and create a great löyly, you need a heater with a lot of sauna stones. There should be gaps between the sauna stones, allowing air to easily pass between them, onto which water can be poured. This creates a heat that is enjoyable and warming, not an uncomfortable radiated heat created by heaters without stones.

2. Durability - A broken heater is no heater at all. Sauna heaters take a lot of punishment. They get very hot (not surprising) and for a proper sauna experience, water should be added to the sauna stones. Your heater should be built well out of high grade materials in order to really last.

3. Authenticity - Sadly most British people experience sauna in their gym's or health clubs, where there is a heater hidden behind a bench with no stones. Any sauna enthusiast will tell you that this is not a pleasant experience, creates a very bad löyly and certainly does not deserve to be called a sauna. To experience proper authentic sauna and gain from the many health benefits, you need a high-quality, authentic sauna heater.

Luckily for you, Narvi, HUUM, Helo, IKI and Tulikivi sauna heaters combine all three of these aspects. The heaters have the large stone capacities and are for the large part built in the Nordics from high quality components and top-grade steel at market-leading thicknesses. Most of our heater brands have been awarded the 'Finnish Key Flag', awarded to authentically Finnish products.
