Space Heaters vs Central Heating: Which Is More Energy Efficient?

January 16, 2026
space heater vs central heating

A space heater is a portable heater that you can place in any space you wish. Unlike a central heating system, it only distributes heat into smaller areas rather than all rooms of your home. Modern space heaters come in a variety of sizes with different wattage. A central heating system is the most popular type of heating in the United States. It is usually powered by electricity or gas. Keep in mind that electricity is the most expensive type of energy used and is the least economic option. Space heaters vs central heating, which is more energy efficient?

Energy Usage

Electric space heaters are not more energy efficient than your gas furnace. In most places, electricity is still a lot more expensive than natural gas. In order to save money with an electric space heater you can use it if you only need to heat up a room or two. The rest of your home will be cooler, but if you are barely in some areas of the home no need to spend money heating up the whole house.

However, you will need to turn down the thermostat to save money. If you don’t turn the thermostat down and end up using both, your bills can increase. The reason for this is because, they are used on top of your central heat and to solve heating inadequacies. Above all, you will want to be sure to turn the space heater off when you are not in the space that it is heating.

Winter Tips

If you are using a space heater to solve heating issues, try addressing the issues first. To make your home more energy efficient and comfortable this winter try implementing the following tips. It is important to regularly maintain the HVAC system. Schedule a furnace tune up before the start of the season to ensure it is operating properly and efficiently as possible.

If your unit is regularly maintained you will be able to catch any minor repairs that need to be completed. If you don’t already have one consider installing a programmable thermostat. By setting the thermostat at a lower temperature while you are away, you can reduce the overall energy costs. Make sure your home is adequately insulated. It is important that your ducts are sealed and insulated properly. Seal drafts coming in through windows and doors. Open your curtains during the day to absorb natural heat from the sun and close them at night to keep the heat in.

Safety First

If you do use a space heater, make sure to follow all safety precautions. Never plug a space heater into an extension cord or power strip. Furthermore, It is important to never leave a space heater unattended or ever be left on in a child or infants room. Do not leave a space heater on overnight. Also, keep everything including furniture and curtains at least three feet away from the space heater. A short circuit, a malfunctioning system or a unit simply getting knocked over can lead to a fire.

A space heater can be used effectively for proving extra heat in your home when needed. It is important to always follow safety precautions when in use.
