We’ll break down exactly how each type works, what they’re best for, and how to pick the perfect one for your comfort. Let’s get your home cozy and warm, the smart way!
Oil Filled Heater Vs Infrared: What’s the Difference?
When you’re looking to boost the coziness of your home, heaters can seem like a great solution. But not all heaters are created equal! Two popular choices for supplemental heating are oil-filled heaters and infrared heaters. They work in very different ways to keep you warm, and understanding these differences is key to choosing the right one for your needs. Let’s dive into what makes each one unique.
How an Oil Filled Heater Works
Think of an oil-filled heater like a gentle, consistent hug for your room. It’s a portable electric heater with a sealed metal casing filled with a special diathermic oil. When you turn it on, an electric element inside heats this oil. The heated oil then circulates through the fins of the heater, warming up the metal casing. This warm casing, in turn, heats the air around it. The warm air rises and circulates throughout the room, creating a consistent and comfortable ambient temperature. It’s a quiet and convection-based heating method.
Because the oil retains heat well, these heaters continue to radiate warmth even after they’ve been turned off, providing a lingering comfort. They are often a good choice for maintaining a steady temperature in a room for extended periods without frequent cycling on and off.
Pros of Oil Filled Heaters:
- Consistent, Even Heat: They warm the air in the entire room, providing a stable and comfortable temperature.
- Quiet Operation: There are no fans, so they operate very silently.
- Safe to Touch: The outer casing gets warm but not dangerously hot, making them safer around children and pets.
- No Odor: They don’t burn dust or other particles, so there’s no unpleasant smell.
- Moisture Retention: They don’t dry out the air as much as some other heater types.
- Lingering Heat: The oil holds heat, so they can continue to warm the room for a while after being switched off.
Cons of Oil Filled Heaters:
- Slow to Heat Up: It takes time for the oil and the fins to get warm, so they aren’t ideal for instant heat.
- Less Energy Efficient for Quick Heating: Since they heat the air, they need to run longer to warm a room compared to direct heat methods.
- Bulky and Heavy: They can be quite large and heavy, making them less portable than some other options.
- Can Be a Fire Hazard if Tip-Over: While generally safe, like any electric heater, they pose a risk if damaged or placed too close to flammable materials. Always ensure they have stable footing.
How an Infrared Heater Works
An infrared heater works more like the sun. Instead of heating the air, it heats objects and people directly using infrared radiation, much like how you feel the warmth of the sun on your skin even on a cool day. Inside, an infrared heater has a heating element that emits infrared waves. These waves travel through the air until they hit a surface – your furniture, your walls, or you! When these waves make contact, they are absorbed and converted into heat. This means you feel warm almost instantly, even if the air around you is still a bit cool.
Infrared heaters are excellent for targeted heating. If you’re sitting in a specific spot, an infrared heater can make that area feel very warm and cozy without needing to heat the entire room. This can be a big energy saver if you only need to warm a small zone.
Pros of Infrared Heaters:
- Instant Heat: You feel the warmth almost immediately as the infrared waves hit you.
- Energy Efficient for Spot Heating: They are great for warming specific areas or people, potentially saving energy by not heating the whole room.
- Noiseless Operation: Most infrared heaters are fanless, so they operate silently.
- Retains Moisture: Like oil-filled heaters, they don’t significantly dry out the air.
- Lightweight and Portable: Many models are compact and easy to move from room to room.
- Can Improve Air Quality: By heating objects and not circulating air, they don’t stir up dust, allergens, or odors.
Cons of Infrared Heaters:
- Doesn’t Heat the Air: The air will still feel cool if you’re not directly in the path of the infrared rays.
- Heat Doesn’t Linger: Once the heater is off, the direct warmth stops immediately.
- Can Be Hot Surfaces: Some infrared heaters have very hot glowing elements or surfaces that could be a burn risk if touched.
- Requires Direct Line of Sight: Objects and people must be in the direct path of the heater to feel the warmth.
- Potential for Overheating Small Spaces: If pointed directly at you for too long in an enclosed space, it can feel intense.
When to Use Which Heater: Scenarios
Choosing the right heater often comes down to how and where you plan to use it. Both oil-filled and infrared heaters have their superpowers, and knowing when to deploy each one can make a big difference in your comfort and efficiency.
Best for Oil Filled Heaters
An oil-filled heater is your go-to when you want to create a cozy atmosphere in an entire room, especially if you need consistent, background warmth. They are fantastic for:
- Warming Bedrooms Overnight: Their quiet operation and gentle heat are perfect for a good night’s sleep without drying out the air.
- Maintaining a Comfortable Living Area: If you spend a lot of time in a living room or den and want the whole space to feel evenly warm, an oil-filled heater is a great choice.
- Supplementing Central Heating: When your main heating system struggles to keep a particular room at a comfortable temperature, an oil-filled heater can provide that steady boost.
- Areas Where Safety is Paramount: For homes with very young children or pets, the cooler surface temperature of an oil-filled heater makes it a safer option compared to heaters with exposed hot elements.
- Long Periods of Use: If you need a space to be warm for many hours a day, the consistent heat distribution is ideal.
Best for Infrared Heaters
Infrared heaters excel when you need quick, targeted warmth without necessarily heating the whole room. They are perfect for:
- Warming Up Quickly: Arriving home on a cold day and want to feel warm instantly? Point an infrared heater at yourself!
- Specific Workspaces: If you have a home office, workshop, or garage where you only spend part of your time, an infrared heater can warm just that spot efficiently.
- Spot Heating in Drafty Rooms: Instead of cranking up the thermostat for the whole house to combat a draft, an infrared heater can provide warmth just where you need it.
- Areas with High Ceilings: In spaces with very high ceilings, trying to heat the entire air volume with convection can be inefficient. Infrared heat bypasses this by warming people and objects directly.
- Occasional Use: If you only need a heater for short bursts of time to take the edge off a chill, infrared is the way to go.
- Complementing Other Heating: Use an infrared heater to feel warmer at your desk while your main heating system maintains a lower overall temperature.
Key Features to Consider When Choosing
When you’re ready to buy, there are a few things to look for that will help you make the best choice between different models. Think about what’s most important to you and your home.

Energy Efficiency and Cost Considerations
When it comes to keeping your home warm, energy efficiency and cost are big factors. Both oil-filled and infrared heaters use electricity, and their efficiency depends largely on how you use them.
Oil Filled Heater Efficiency
Oil-filled heaters work on the principle of convection. They heat the air in a room, and that warm air circulates. They are efficient when you need to maintain a steady, comfortable temperature over a long period. Because they continue to radiate heat even after being turned off, they can sometimes reduce the number of times the heating element needs to cycle on. However, they are less efficient if you only need heat for a short burst, as it takes time for them to warm up.
The operating cost will depend on your local electricity rates and how many hours you run the heater. Using the thermostat to maintain a consistent, moderate temperature is key to managing energy use. For example, setting it to 68°F (20°C) is generally considered a comfortable and efficient temperature for occupied living spaces, according to the U.S. Department of Energy.
Infrared Heater Efficiency
Infrared heaters are incredibly efficient for spot heating because they directly warm people and objects. If you only need to warm yourself while you’re working or relaxing in a specific spot, an infrared heater can achieve that feeling of warmth much faster and with less overall energy than trying to heat the entire room with a convection heater. They don’t waste energy heating air that will simply rise or be lost to drafts.
However, if you try to use an infrared heater to warm a large room or multiple people, it won’t be as effective or energy-efficient as a convection heater designed for that purpose. The cost-effectiveness comes from directing the heat precisely where and when it’s needed.
Safety First: Using Your Heater Responsibly
No matter which type of heater you choose, safety is always the top priority. Using electric heaters responsibly ensures you can enjoy warmth without any worries. Here are some essential safety tips for both oil-filled and infrared heaters:
General Safety Tips for All Heaters:
- Read the Manual: Always read and follow the manufacturer’s instructions for your specific heater model.
- Clearance is Key: Keep heaters at least 3 feet (about 1 meter) away from anything flammable, including curtains, furniture, bedding, and paper.
- Stable Surface: Place heaters on a firm, level, and non-flammable surface. Never place them on top of furniture, rugs, or in places where they can easily be tipped over.
- Never Leave Unattended: Do not leave older electric heaters running when you are asleep or out of the house. Modern heaters with safety features like tip-over protection are often designed for this, but caution is always wise.
- Check the Cord: Inspect the power cord regularly for any damage. If the cord is frayed or damaged, do not use the heater.
- Don’t Use Outdoors: Most indoor electric heaters are not designed for outdoor use and could be damaged or pose a safety risk if used in wet conditions.
- Avoid Extension Cords: If possible, plug the heater directly into a wall outlet. If an extension cord is necessary, ensure it is heavy-duty and rated for the heater’s wattage.
Specific Safety Tips:
- Oil-Filled Heaters: While their surfaces are generally cooler, always ensure they have stable footing and check for any leaks.
- Infrared Heaters: Be especially mindful of the glowing elements or hot surfaces. Keep them out of reach of children and pets, and ensure they are not placed too close to sensitive materials.
Frequently Asked Questions (FAQ)
Q1: Which heater is better for a very cold room?
For sustained warmth in a consistently cold room, an oil-filled heater is usually better because it heats the entire air volume more effectively over time. An infrared heater would only warm the person or object directly in its path.
Q2: Can I use an oil-filled heater in my bathroom?
Generally, it’s not recommended to use any portable electric heater in a bathroom due to the high moisture levels and water, which can pose a significant electrical hazard. Always check the heater’s manual and ensure it’s rated for bathroom use, which is rare for portable heaters. Many bathrooms rely on built-in heating solutions or ventilation.
Q3: How quickly does an infrared heater warm a space?
Infrared heaters provide near-instant warmth to people and objects in their direct path. You’ll feel the heat as soon as you turn it on and are positioned correctly. However, it doesn’t heat the air itself, so the ambient temperature of the room might not change much.
