During winter, for many of us, comfort at home means heat.
While a good central heating system is designed to meet whole-house needs, sometimes consumers turn to space heaters for additional warmth. Some people use one to boost temperatures for a single room where the available heat is inadequate, but their widespread use over extended periods can boost winter heating bills.
“In some cases, small space heaters can be less expensive to use if you only want to heat one room or supplement inadequate heating in one room,” according to U.S. Department of Energy analysts. “However, a space heater is not necessarily an economical source of long-term warmth. It is not an alternative to a whole-home heating system.”
Safety. First.
First: A note on space heater safety.
Space heaters are only used seasonally but are responsible for 25,000 residential fires a year, according to the U.S. Consumer Product Safety Commission, which pegs the annual mortality rate at 300 a year. Burn injuries associated with surface contacts with room heaters send about 6,000 people to emergency rooms every year, and most of those incidents don’t result in fires.
Because the devices are designed to give off heat, they should always be set in locations clear of all flammable materials and out of reach of small children, pets, or anyone with impaired mobility.
In recent years, many space heaters have been designed with tip-over safety features, which automatically shut off the power source in the event that the unit tilts beyond its upright position.
Because space heaters are designed specifically to produce heat, they should be plugged directly into a wall whenever possible. If an extension cord is used, it should be heavy-duty and made of 14-gauge wire or larger.
Given a choice between high, medium, and low, or an adjustable thermostat, choose the latter. A unit that heats your space to the desired temperature will cycle less, saving you energy and never overheating the room.
And buy the right size heater for the right size space––too small and the warming results could be disappointing, too large or powerful and you’ll be uncomfortable. Any time you open doors or windows to vent away warm air, you are wasting energy you’ve already consumed to produce heat.
Getting More for Less
“Space heaters are not the ideal solution for heating homes,” said Brian Sloboda, a senior program manager for the National Rural Electric Cooperative Association (NRECA). “For every unit of electricity that is consumed by these devices, they produce one unit of heat.”
While adding several space heaters to supplement your central heating system is also likely to drive up your energy costs, selective use can help you save money.
According to analysts at the Environmental Protection Agency (EPA), the key is using space heaters in smaller rooms that are occupied infrequently, in conjunction with lower thermostat settings on your central system.
Lowering thermostat settings from 70 to 65 degrees and using a thermostat-controlled space heater to heat 10 percent of a home’s conditioned floor space will save a heat pump user $67 a year. However, the EPA cautions that space heaters are most efficient when used in small spaces for limited periods and can actually waste energy if consumers try to heat too much area with the devices.
There are currently no space heaters among the EPA’s list of ENERGY STAR®-rated products. Agency officials said they have evaluated several models but have no plans to include such products in the labeling program in the near future.
Still, high-end space heaters are heavily marketed during the autumn and winter months.
“Most of these units are very similar in design, but the cabinetry or packaging are major selling points,” said Sloboda. “Consumers should consider the wide range of heaters available and their own taste in features and design before buying one.”
Our co-op’s energy experts can help determine if a space heater is right for your home.
“Energy advisors may suggest other alternatives, like sealing air leaks, adding insulation, or tuning up your heating system so it operates more efficiently,” said Sloboda. “Those are just a few alternative options that won’t increase your overall energy use.”
