Forget about planning, advance programming, and heating times! This high tech Sauna heater offers a breakthrough in Sauna heating. There is no 30 minute heat up time--the Sauna is ready when you are! Thanks to microceramic insulating technology (similar to that used in the space program), and an extremely large stone capacity, the Ever Ready stores thermal energy, and with its basic power of 250 watts, the heater is ready instantly. One can go into the Sauna, pop open the heater lid, turn on the venturi action vent, and instantly enjoy soft heat and outstanding steam production. When not being used, the Ever Ready consumes the same amount of energy as 3 light bulbs. Ideal for home use, the heater needs no fence because it has the coolest casing of any Sauna heater on the market. Available in 4 and 6 kW sizes.
