The heater is an essential part of a sauna. Heaters run on gas, electricity and wood. To enhance the life of the heater element, water should be used sparingly. The size of the sauna room determines the required number of heaters.
When searching for a sauna heater, there are several factors to keep in mind. To begin, you might want your heater to have 3-wall construction. This allows it to have a cooler surface temperature, which increases safety. Likewise, your sauna heater should be UL tested and listed.
Other indicators of quality heaters are that they have stainless steel elements, which aid in extending the life of the heater. Likewise, good heaters have a large rock capacity for heat storage. And, they have direct rock contact with the heating elements. This is needed to filter the harsh heat radiating from the 1400? F elements and to get rid of the electromagnetic field for safe and therapeutic bathing. Specifically, the person feels only comforting heat rather than blasting heat. It also produces the best steam when water is poured over the rocks.
A sauna heater is an essential element as without it, the sauna is rendered useless. While there is always a tradeoff between the price of a heater and the quality, make sure you find a heater with the key quality indicators listed above.
