Question: are cadet heaters expensive to run?
Answer: First thing we need to do is convert the watts into kilowatt-hours by dividing by 1,000. The answer is 1.5, which means the two heaters will use 1.5 kW of electricity each hour they are in use. ... In this case, it would cost us $0.12 per hour to use the two heaters or $2.92 to run them constantly for 24 hours.
