When the colder months hit, we all know how important it is to stay warm indoors. But have you ever stopped to think about the type of heater you’re using? Different room heaters can affect your comfort in different ways, and it’s important to pick the one that works best for your needs.
Whether you’re considering a fan heater, an oil-filled radiator (OFR), or an infrared heater, each option has its own strengths. Some work quickly, while others offer more consistent warmth. The key is understanding how each type of heater works, and how it fits into your space and lifestyle.
In this guide, we’ll break down the differences between fan heaters, OFR heaters, and infrared heaters, so you can make a more informed decision about which one is right for you. Let’s take a look at what each heater brings to the table, and why picking the right one matters for your comfort this winter.
How do these 3 types of room heaters work? Let’s break it down
When it comes to keeping warm during the colder months, it’s important to understand how different heaters function. Every room heater uses a different method to heat the air and make your space more comfortable. Let’s look at the most common heating methods used in today’s heaters.
1) Fan heaters: Think of fan heaters as the quick fix for a chilly room. Inside these devices is an electric heating element, often made of metal or ceramic. When you switch it on, electricity flows through the element, warming it up. A fan placed behind the heating element blows air across it, circulating the warmth throughout the room. This is similar to the way a hairdryer works – it uses air movement to spread heat quickly. For example, if you have a fan heater in your office or home, you’ll notice that it warms up the space in a matter of minutes. However, once you turn it off, the heat doesn’t last long because it’s the air that’s been heated, and it starts to cool down fast.

2) Oil-Filled Radiators (OFR) heaters: Now, oil-filled radiators are a bit different. They don’t use a fan to circulate warm air. Instead, they rely on oil that heats up over time. Inside the radiator, the oil is heated by an internal element, and it then radiates heat throughout the room. The oil acts as a heat reservoir, so it continues to release warmth long after the heater is switched off. For example, suppose you’re in your living room on a chilly evening with an oil-filled radiator gently warming the space. The heat spreads evenly and lingers even after it’s switched off, creating lasting comfort. Unlike fan heaters, an OFR offers steady warmth without harsh drafts.

3) Infrared heaters: Infrared heaters work by directly heating objects and people rather than the air. These heaters emit infrared radiation, similar to the warmth you feel when you stand in the sun. The rays directly hit surfaces, heating them up. For example, if you have an infrared heater near your desk, you will feel warmth almost immediately, but the room itself might still be cool. These heaters are perfect for targeted heat. If you’re sitting by the heater, you will feel cosy even in an otherwise cold room, but it won’t be the best choice for warming the whole space.

Innovative room heater features to watch out for: Fan, OFR, and infrared room heaters
When shopping for a room heater, understanding the innovative features specific to each type can help you make a more informed choice. Here’s a look at some standout features across the three most common heater types: fan heaters, oil-filled radiators (OFR), and infrared heaters.
1) Fan Heaters: Speed and versatility
- Dual heat settings: Many fan heaters come with adjustable heat settings (e.g., 1000W and 2000W), allowing users to choose between quick warmth and more moderate heating.
- Oscillation function: Some fan heaters feature oscillation, which allows the heat to spread more evenly across the room, rather than concentrating in one spot. This is especially useful in medium-sized rooms.
- Overheat protection: Advanced fan heaters now come with overheat protection sensors, ensuring the heater shuts off automatically if the temperature exceeds a safe level. This adds an extra layer of safety for household use.
2) Oil-Filled Radiators (OFR): Comfort and durability
- Thermal cut-Off technology: OFR heaters often come with thermal cut-off technology that ensures the unit will turn off once it reaches a certain temperature, helping to avoid overheating and ensuring consistent safety.
- Adjustable thermostat: Many modern OFRs come with adjustable thermostats that allow for precise control of room temperature. This feature is especially useful for maintaining an ideal environment over long periods.
- Portable and easy to store: While larger in size, many OFR models are designed with wheels and a compact frame, making them easy to move and store after use, which adds to their convenience, especially in small spaces.
3) Infrared Heaters: Focused, energy-efficient heat
- Carbon fiber heating elements: Some of the latest infrared heaters use carbon fiber heating elements, which are more energy-efficient and durable compared to traditional metal elements. These offer quicker heat-up times and reduced glare, ensuring a comfortable heating experience.
- Remote control functionality: Many infrared heaters come with remote control options, allowing users to adjust settings like temperature and heat output without leaving their seat. This makes it a convenient option for people using the heater in specific, stationary areas like their office or reading nook.
- Adjustable heat angle: With adjustable heat direction, some infrared heaters allow you to direct heat precisely where you need it. This feature can make them ideal for targeted heating in larger rooms or for specific individuals sitting near the heater.

Which room heater takes the lead: Fan, OFR, or infrared?
When it comes to warming up your space, oil-filled radiators (OFRs) emerge as the true winner. While fan heaters deliver quick heat and infrared heaters target specific areas, OFRs shine with their consistent warmth, energy efficiency, and quiet operation. They provide long-lasting comfort, making them the go-to choice for reliable, all-around heating. For a steady, energy-efficient solution that stands the test of time, an OFR is the clear champion in the room heater race.

FAQs on fan vs OFR vs infrared room heaters
- Which room heater is the most energy-efficient?
Infrared heaters are the most energy-efficient. They directly heat objects and people, minimising energy wastage, unlike fan heaters that heat the air or OFRs that require longer heating times.
- Can an oil-filled radiator heat a large room effectively?
Yes, OFRs are great for heating larger rooms. Their slow but consistent convection heating ensures that warmth spreads evenly over time, making them perfect for sustained heating in spacious areas.
- How quickly do fan heaters heat up a room?
Fan heaters are the fastest to heat a room. They blow hot air almost immediately after being turned on, making them ideal for quick, short-term warmth in small spaces.
- Are infrared heaters safe for indoor use?
Yes, infrared heaters are completely safe for indoor use. They emit safe, non-toxic infrared radiation that warms people and objects without raising the temperature of the air, making them ideal for localised heating.
- Are oil-filled radiators (OFRs) safe to leave on overnight?
Yes, oil-filled radiators are generally safe to leave on overnight, as they use a sealed system and operate at lower temperatures once heated. However, it’s always recommended to follow manufacturer guidelines and ensure the heater is placed on a stable surface in a well-ventilated area for safety.
