The Scandia Sauna heater line was developed in 1964 with the goal of developing the only line of convection air-flow sauna heaters. By achieving greater air-flow, the heater can heat the room more rapidly and extend the life of the heater elements. This is accomplished by a unique element chamber design that separates each element. By restricting air space, the lower cold mass of air forces the warm air out at a higher velocity. In traditional saunas, where the elements are grouped together in the chamber, the elements radiate heat against each other forcing the elements to work at a higher temperature and for longer periods of time compared to a convection design.
