Simply find the wattage of your space heater on the box or in the user manual. Multiply this by the number of hours you will use it, and divide that number by 1,000. Then, multiply this figure by the kilowatt-hour rate charged by your utility company, and you will know how much that space heater is costing you.”

“So, if you have your heating on all the time, your heating system will be using energy on an ongoing basis to maintain the inside temperature.

But, the greater the heat loss from your home, the more energy you will need to maintain the inside temperature, which means that the cost of leaving your heating on all the time will be especially expensive.

This all means that leaving your heating on all the time will drain a lot more energy from inefficient homes, as the heating works a lot harder to replace lost heat.”
