How hot does a 1500-watt heating element get?
A standard 1500-watt heater running on 120 volts of electricity generates around 5100 BTUs of heat. BTUs are used to measure the amount of heat found in anything that puts out heat, such as a water heater or a furnace. \
This will heat up around 150 square feet of space, which is about the size of any medium-sized room, such as an office or a spare bedroom. \
