“Remember, space heaters can save you money if used correctly. Turn down your main thermostat and use the space heater to warm up the rooms you use the most.”
7. Common Myths About Space Heaters
7.1 Energy Consumption Myths
Do space heaters use a lot of electricity? The answer depends on several factors, including the heater's wattage and how long you use it. While space heaters can consume a considerable amount of electricity, they are often more efficient than central heating systems for heating small, targeted areas. Is it cheaper to run space heaters or central heat? Generally, using space heaters can be more cost-effective if you only need to heat a specific room rather than your entire home. This allows you to lower the thermostat on your central heating system, reducing overall energy consumption. However, it’s essential to consider the size of the space and the heater's energy consumption. For optimal savings, use space heaters in well-insulated rooms and only when necessary. Ultimately, understanding your heating needs and the efficiency of your heating options can help you make informed decisions about your energy use.
