As a basic rule of thumb, all electric-resistance based heaters working at the same voltage (110v most common) are equally efficient and they will all put out the same amount of heat for the amount of electrical energy consumed. A 750 watt heater will put out half the heat of a 1500 watt and might seemingly cost half as much to operate, but if it needs to run twice as long to maintain temp it makes little difference. One other important factor is circuit load. A smaller wattage heater uses less current so you are less likely to trip a breaker if you have a the heater and a toaster or hair dryer operating at the same time on the same circuit.
Sorry, there was a problem. Please try again later.At 1500 watts, you can't run much of anything else on a 15 amp circuit. 1500 watts is drawing 12.5 amps.
