The bench heater in all Health Mate Saunas is the lowest-watt heater in the cabin. This heater is designed to give half the amount of infrared heat as the heaters in the back or the front of the sauna. With the bench heater being right next to the legs, we designed it for maximum comfort for our customers.
If the bench heater is not properly heating, try flipping the switch off and then on again, and that should reset the heater so it will warm up properly.
