HUUM vs Saunum: which heater fits your sauna?
HUUM is an Estonian brand known for open stone heaters, where the stones themselves give the heater its shape. Saunum is an Estonian brand whose Air heaters have a built-in fan that mixes the air, to even out the temperature between floor and ceiling. Both make good heaters; what matters is which models are rated for your room.
