What to Avoid
Don't buy a heater that is not thermostatically controlled. If you can't control the heat output, it can end up costing a lot more in the long run.
Don't believe marketing that claims to raise humidity levels. While using an infrared heater rather than forced air heating can keep the air from drying out quite as fast, you will not magically raise your humidity level simply by using an infrared heater to provide auxiliary heat.
Electric infrared heaters can range in price from less than $50 for small portable desktop units to more than $1,000 for decorative fireplace look-alike units. Generally, for a decent model with thermostatic controls, you can expect costs to be in the $100 to $300 range.
High price does not guarantee better energy savings; prices are inflated in some cases simply because demand is high and brands are limited.
Features, construction, and heating technology tend to differ among infrared models and consumers should compare heaters to get the best value for their money.
Infrared Heater Use and Care Tips
Larger units (1500 watts or more) should be connected to a 20-amp outlet, or, if connected to a 15-amp circuit, it should be dedicated to the heater only. A 1500 watt heater will draw up to 12.5 amps of power, which can cause a 15-amp circuit to overload if other lights and appliances are also running off it.
Most models of infrared heaters have cool-to-touch exteriors and are safer to use with young children and pets in the home. Though clearances are not as much an issue as with hot-coil heaters, you should remove clutter in the heater's area to ensure that heat can freely be dispersed to the room. As with any electrical heater, keep papers, clothing, magazines and other items away from the heater.
Use of extension cords is not recommended but when you must, ensure that the power bar or extension cord is rated for the wattage rating of the heater. Always check to make sure that the heater is UL certified before using.
Infrared heaters are designed to be room (zone) or space heaters. Though some may boast a capacity to heat a large area, an infrared heater should not be used as a home's sole heating unit, but as a supplemental heater to your central heating furnace or system.
By using an infrared unit as a zone heater, you can reap some energy savings by turning down your central heating system and adding warmth to the space or zone that you use the most. A zone heater such as an infrared heater is ideal in a family room, insulated garage or open living space.
