Infrared vs Convection Heaters: What Buyers Should Know

You've seen the comparison charts. Infrared vs convection heaters. Both claim to be the best for energy savings. But if you're sourcing for a market, you need to know which one your customers will actually want to keep. Let's cut through the marketing.

How They Actually Work

Convection heaters pull cold air in, heat it with an element, and push it out. They warm the whole room gradually. Think oil-filled radiators and wall-mounted panels. They take 10 to 20 minutes to feel warm, but they keep the temperature steady.

Infrared heaters don't heat the air. They emit infrared radiation that warms objects and people directly. You feel it in seconds. The room air stays cooler. This is a fundamental difference that affects everything else.

The Real Differences for Buyers

Warm-up time

If your customer wants heat now, infrared wins. A person standing in front of an infrared panel feels warmth in under a minute. Convection takes longer. For a bathroom or a home office where someone wants quick heat, infrared is the obvious choice.

Whole-room heating

Convection wins for a large room. It heats the air, so the whole space becomes comfortable. Infrared only heats what's in its line of sight. If your customer needs to heat a garage or a workshop with drafty corners, convection is more practical.

Energy efficiency

This is where buyers get confused. Both types are nearly 100% efficient at converting electricity to heat. The difference is how they're used. Infrared is more efficient if you only need heat for short periods. You turn it on, feel warm, turn it off. Convection is better for maintaining a constant temperature over hours. So an energy efficient electric heater for a bedroom that runs all night? That's convection. A low wattage electric heater for a small office where someone sits for an hour? Infrared.

Running cost

Electricity is electricity. A 1500W heater costs the same to run regardless of technology. But because infrared heats the person, not the room, you can use a lower wattage and still feel comfortable. A 600W infrared panel can feel as warm as a 1500W convection heater if you're nearby. That's the real saving. But if the room needs to be warm, you'll need the same wattage as any other heater.

Comfort and air quality

Convection heaters create air movement. Dust and allergens get stirred up. They also dry out the air. Infrared doesn't move air, so it's better for people with allergies or asthma. There's also no fan noise with infrared, which makes it a strong silent electric heater option for a bedroom. But convection oil-filled radiators are also silent. They just take longer to warm up.

The Oil-Filled Radiator vs Convection Heater Question

This is a common comparison in our factory. Oil-filled radiators are a type of convection heater, but they're different from fan heaters or wall-mounted panels. Oil-filled radiators use oil as a heat reservoir. They heat up slowly, but they retain heat longer. They're heavier and more expensive to ship. Wall-mounted convection panels are lighter, cheaper to ship, and easier to install. Both are good for whole-room heating. The choice depends on your market. In Europe, oil-filled radiators are popular because they're silent and have good thermostats. In the US, wall-mounted panels are gaining ground for their space-saving design.

What to Source for Your Market

Let's talk about your customers' use cases.

For a bedroom or office

A wall-mounted convection panel with a thermostat is a solid choice. It's quiet, doesn't take floor space, and can be set to maintain a constant temperature. Look for models with an energy-saving mode and programmable timer. Our 500W to 1500W panels are CE and RoHS certified, and we offer OEM branding.

For a bathroom

You need IP24 rated heaters. That means they're splash-proof. Both infrared and convection can be IP24, but infrared is better because it heats you directly. You don't need to heat the whole bathroom. A 400W to 800W infrared panel is enough for most bathrooms.

For a garage or workshop

You want a fan heater or an infrared heater with high wattage. The key is to warm the person, not the whole concrete box. An infrared heater with a high output, like 2000W, can make a work area comfortable quickly. But if the garage is well insulated, a convection heater might be more even. Think about what your customer already has. If they have a drafty garage, they need infrared.

For a greenhouse

This is a special case. Greenhouses need constant heat to protect plants from frost. Convection heaters are better because they maintain air temperature. But they must be IP rated for damp environments. We make 1200W greenhouse heaters with IP44 protection and a thermostat.

What About the Infrared vs Convection Heater Energy Efficiency Question?

Buyers often ask us which is more energy efficient. The honest answer is: it depends on usage. If you heat a room for 8 hours a day, convection is more efficient because it doesn't cycle on and off as much. If you heat for 30 minutes at a time, infrared is more efficient because you don't waste energy heating the air. There's no universal winner.

A Word on Safety

Both types are safe if they meet standards. Look for CE, UKCA, or ERP certifications depending on your market. Also check for overheat protection and tip-over switches. For wall-mounted units, make sure the mounting brackets are solid. We've been manufacturing since 2009, and we've seen cheap units fail because of poor connections. That's a safety issue.

The Takeaway

Don't pick a technology because it's trendy. Pick it based on the use case and your customer's climate. If they need instant heat in a small space, go infrared. If they need whole-room comfort, go convection. And if you're not sure, ask us. We'll tell you what we'd source for our own brand. That's the honest advice.

We do OEM and private label. Our standard MOQ is 200 pcs per model, and lead time is 15 to 45 days depending on quantity and finish. We have CE, RoHS, UKCA, and ERP certifications. But don't contact us just because we said that. Contact us when you have a product spec in mind. We'll give you a straight answer.
