hi kev , the old mytee had just one 2000watt , the new one has 2 x1000 watt heaters , (sorry steve u are right) but they would both performe the same same watts, the v2 is one 3000 watt heater which will and can prouduce steam at 100ft in bursts and maintain temps of 70 plus with cont use , but it still needs a hot water supply to do this , the mytee ones will not heat the water fast enough to keep up with the v2 , the cfr claims are bull
