Eden pure heaters?
67DART273 is correct. there is no changing OHMS LAW
The higher the wattage the more energy consumed. FACT
A 4000 watt heater will produce more heat than a 1500 watt heater but it will always consume more power when on.
Also wattage is wattage no matter how fancy one looks over the other
You cannot create more energy than you put in.
Unless of course you have a water fusion reactor that works which in that case email me!!!!!!!
