This is important if you want to move your heater around, as heaters with mains power cables will be limited by available outlets. Power source describes whether a heater uses a mains power cable, standard batteries or rechargeable batteries for power. Radiant heating is usually more efficient, and both infrared and halogen heaters use radiant heating. Radiant heating warms up your body and other surrounding objects directly, whereas convection heating warms up surrounding air which then warms your body. Heating method usually describes whether a heater uses radiant or convection heating. The required wattage drops to around 7 watts if it’s a secondary source of heat. When comparing heaters, it is estimated that you need 10 watts of output per square foot of space if the heater is your primary source of heat. This means that you can use wattage as a means of comparing the energy/heat generation of different heaters. In the context of heating systems, higher electrical output results in greater heat generation. Wattage measures energy output, describing the amount of energy generated or used. This demonstrates that infrared heaters will likely save you money on replacements in the long term.Ĭomparing heating systems can be an overwhelming task, so we’ve created this list of some of the key terms to help you consider what factors need to be compared. On the other hand, the ~100,000 hour average lifespan of infrared heaters means you would only have to buy a replacement every 11.4 years on average. The ~8,000 hour average lifespan of halogen heaters means that you’re going to have to buy a replacement heater around once a year. We can also see that another key difference is average lifespan. On the other hand, if the two heaters were equally efficient, you’d be paying more money for no benefit. For example, if an infrared heater can heat a room 50% more efficiently than a halogen heater can, a 25% higher cost per hour is worth the increase in efficiency. This doesn’t tell the full picture though, as you have to also consider the effectivity of the heater. Let’s look at a summarised comparison of both halogen and infrared heaters.Īs you can see, the higher average wattage of infrared heaters results in a higher average electricity consumption per hour. This direct heat transfer is the same transfer that we experience in environments warmed by the sun, and it’s the most efficient heating process for our body. They emit infrared radiation that directly heats walls, floors and objects, as opposed to traditional convection heaters that heat up surrounding air. Infrared heaters work through the conversion of electricity into radiant heat. This process allows halogen lamps to operate at much higher temperatures then conventional bulbs, meaning that they can be used as a heat source. This extends the overall lifespan of the filament and prevents blackening of the bulb in the longer term. When activated, the halogen gas reacts with evaporating tungsten, redepositing the tungsten back on the filament in the bulb. Halogen heaters use a small amount of halogen gas within a heating bulb. They both have their pros and cons, so we’ve highlighted some of the key considerations below. Halogen and infrared electric heaters are both energy efficient and reasonably priced, so it can difficult to know which is best for you.
