Majority saunas feature a control panel on the outside of the unit where the user can set the time, heat, activate lights, etc. But that is not all! It is essential that your sauna also have a control panel inside so you don’t need to leave the sauna to make any modifications.There’re 2 different kinds of heat discharger: carbon and ceramic. Many low-quality saunas sold over the web employ ceramic coils or rods in their panels. High-quality carbon panels offer the most enjoyable far-infrared heat accessible. They heat up quicker and offer a much broader heat distribution so you will not get ‘cold spots’ or ‘hot spots’ in your saunas as it’s usually happen with ceramic heaters.Buy infrared sauna heaters and other accessories at Northern Lights.
