At a glance: convection heating warms the air, whereas infrared heating warms people and surfaces directly.<\/strong> If a room is in constant use and you want consistent, wall-to-wall warmth, a convection heater is usually the way to go. On the other hand, if you heat a space intermittently, need targeted zone heating, or are dealing with high ceilings, drafts, or frequently opened doors, infrared heating delivers the same perceived comfort faster and at a lower air temperature. Both convert electricity into heat at virtually 100% efficiency\u2014meaning the real difference in running costs comes down to how much air volume you actually need to heat.<\/p>\n\n\n\n

How Convection Heating Works<\/h2>\n\n\n\n

A convection heater works by warming the air immediately surrounding its internal heating element. As this warm air expands and rises toward the ceiling, cooler air is pulled in from below to replace it, establishing a continuous convective loop. Interestingly, even standard wall-mounted “radiators” are misnamed: conventional wall-mounted radiators emit 80\u201390% of their heat via convection<\/a> and only 10\u201320% through actual thermal radiation.<\/p>\n\n\n\n

The clear advantage of convection is uniform heat distribution. Because warm air circulates freely, it travels behind sofas, wraps around furniture, and reaches floor areas that direct radiant heat cannot see. Convector heaters are quiet, cost-effective to buy, and excel at holding a steady room temperature when paired with an accurate thermostat.<\/p>\n\n\n\n

Their major downside is thermal stratification in tall spaces, alongside an acute vulnerability to drafts. In a room with standard ceiling heights, stratification is negligible: in a near-zero-energy test facility at Tallinn University of Technology, the vertical temperature gradient in a radiator-heated room averaged just 0.13 \u00b0C per meter<\/a>. In high-ceiling industrial or commercial halls, however, that gradient often climbs to 0.5\u20131 \u00b0C per meter. In an 8-meter-tall warehouse, that means the air near the roof can sit 4\u20138 \u00b0C higher than at floor level\u2014wasting substantial energy heating empty air. Worse still, every open bay door allows that reservoir of trapped heat to spill straight outside.<\/p>\n\n\n\n

How Infrared Heating Works<\/h2>\n\n\n\n

An infrared heater emits electromagnetic thermal radiation that travels straight through the air without heating the atmosphere itself. When these infrared waves hit a solid object\u2014such as human skin, a floor, or a desk\u2014their energy is absorbed and converted into heat. Those warmed surfaces then gently radiate heat back into the surrounding room air. In flat infrared panels, radiant heat accounts for at least two-thirds of the total heat output.<\/p>\n\n\n\n

Why does this cut energy use? Human thermal comfort is governed by “operative temperature.” In still air (speeds under 0.2 m\/s), operative temperature is roughly the midpoint between ambient air temperature and the mean radiant temperature of surrounding surfaces. For instance, an air temperature of 22 \u00b0C with 18 \u00b0C surfaces feels identical to 18 \u00b0C air with 22 \u00b0C surfaces\u2014both register as an effective 20 \u00b0C to your body. Because infrared panels elevate surface temperatures directly, you can dial down the air thermostat while enjoying identical comfort.<\/p>\n\n\n\n

For everyday living spaces, far-infrared “dark” or zero-light panels (which produce no visible red glow) are standard. Outdoor patios typically rely on quartz or carbon medium-wave infrared heaters for a more concentrated, weather-resilient heat beam. Meanwhile, uninsulated construction sites and large industrial bays frequently turn to diesel-fired infrared units.<\/p>\n\n\n\n

Which Is Cheaper to Run?<\/h2>\n\n\n\n

At the point of use, all direct electric resistance heaters convert 1 kWh of electricity into roughly 1 kWh of usable heat, regardless of whether they rely on convection or infrared rays. To put that in perspective, a 2025 UK government study on infrared heating noted that a modern heat pump delivers roughly 3 kWh of heat for every 1 kWh of electricity consumed. If you have access to a heat pump, neither direct electric option will beat it on operational cost; both are primarily intended for targeted zone heating or supplementary use.<\/p>\n\n\n\n

Infrared heating saves money only when applied strategically: either by allowing a lower overall ambient thermostat setting or by heating solely occupied zones. According to the European Commission, turning down the thermostat by 1 \u00b0C saves approximately 7% on heating energy<\/a>. Real-world findings reflect this sensitivity to application: in a 2010 commercial office trial, radiant ceiling panels used up to 39.1% less energy per day than portable oil-filled radiators while maintaining equivalent comfort. Conversely, independent testing by a New Zealand consumer advocacy group revealed that running costs for 450 W infrared panels were practically indistinguishable from other standard electric heaters when asked to heat entire rooms.<\/p>\n\n\n\n

A realistic example:<\/strong> Imagine a 15 m\u00b2 home office occupied for 8 hours a day. Maintaining 21 \u00b0C with a standard convection heater might require an average draw of 600 W, consuming 4.8 kWh over the workday. With a properly positioned infrared panel, you might achieve the same personal comfort at an ambient temperature of 19.5 \u00b0C. That 1.5 \u00b0C thermostat reduction trims energy demand by roughly 10%, saving around 0.5 kWh per day. At an all-inclusive electricity rate of \u20ac0.20\/kWh (covering grid fees and taxes), you save roughly \u20ac0.10 a day\u2014or \u20ac2 to \u20ac3 a month. The savings are real, but modest.<\/p>\n\n\n\n

Now imagine a garage workshop used for two hours an evening. A convection heater would need to run for an hour beforehand to warm thousands of cubic feet of cold air\u2014only to lose that heat whenever the garage door cracks open. A 1,200 W infrared panel mounted over the workbench warms you within moments of flipping the switch and draws zero power the rest of the day. In that scenario, energy savings are substantial.<\/p>\n\n\n\n
