It’s a bold claim to be the world’s best electric sauna heater, but this remarkable stove is widely accepted as being just that. Designed by Finnish designer Ristomatti Ratia, the Helo Saunatonttu has a huge range of patented features. These features include super-insulated chassis and ever-ready heat retention plus it holds a substantial 100kg of sauna stones. The large volume of sauna stones and unique insulation mean this popular home sauna heater retains lots of heat. Not only that, it’s ready to go at a moment’s notice. You can expect the home sauna bathing experience to be soft, humid and steamy. Floor standing installation means it can go anywhere in the room.
