Buying guide: Everything you need to know about the best room heaters for every budget and space

This buying guide for the best room heaters is intended to help you navigate the variety of options available. It guides you through important factors such as safety features, energy efficiency, noise levels and ease of use. Whether you’re looking for a heater that’s energy efficient, portable, or fast-acting, this guide will help you select the best room heater on Amazon for your home and budget. By considering the size of your room, your heating needs and preferences, you can make an informed decision and enjoy a warm, cozy home all winter long.

What different types of room heaters are there for different rooms?

Room heaters come in different types, including convector heaters, radiant heaters, oil-filled heaters and fan heaters. Convection heaters warm the air in the room and provide consistent, even heat. Radiant heaters emit infrared radiation that heats objects directly, quickly heating specific areas. Oil-filled heaters use heated oil to generate heat, creating long-lasting heat but taking longer to heat up. Fan heaters distribute warm air quickly, but can be noisy. The type of heater you choose depends on the room you want to heat, but also on your preference for speed, efficiency and noise level.

Which room heater is best for large rooms?

For large rooms you need a heater that provides powerful heating power. Oil-filled radiators and convection heaters are ideal for larger spaces because they provide consistent heat over time. Oil-filled heaters take longer to heat up, but retain heat for a longer period of time and are ideal for areas where you need continuous heat. Convection heaters, on the other hand, heat the air in the room faster, making them suitable for larger rooms when you need direct heat.

Should I buy a fan heater or an oil-filled heater?

When choosing between a fan heater and an oil-filled heater, the main factors to consider are speed, energy efficiency and how long the heat lasts. Fan heaters are ideal for quickly heating up a room, making them ideal for short bursts of heat or smaller spaces. However, they tend to use more energy and can dry out the air. On the other hand, oil-filled heaters provide more consistent and long-lasting heat. They are energy efficient in the long run because they retain heat for hours even after they are turned off. Although they take longer to heat a room, they are much quieter and better suited to larger or colder rooms. Here’s a comparison between the two to help you make an informed decision:

Function	Fan heater	Oil-filled heating
Speed	Fast, heats the room quickly	Slower, it takes time to warm up
Energy efficiency	Less efficient, uses more power	More energy efficient, retains heat longer
Noise level	Can be noisy because of the fan	Quiet operation, no fan noise
Portability	Lightweight and easy to move	Heavier and less portable
Air quality	Can make the air dry	Does not affect humidity
Eligibility	Ideal for small spaces and quick heat	Suitable for larger rooms, longer lasting heat
Costs	Generally cheaper	Usually more expensive upfront

How do I choose a room heater based on the size of the room?

Choosing the right room heater based on room size is essential for both efficiency and comfort. A heater’s wattage plays a key role in its heating capacity, and by selecting the right size you can get the most out of your heater without wasting energy.

For smaller rooms (up to 100 square meters), a heater with a power between 1000 W and 1500 W is usually sufficient. These heaters can heat the room quickly and efficiently without consuming too much energy. They are perfect for bedrooms, small offices or personal spaces, where heating needs are relatively low.

For medium-sized rooms (100-200 square meters), a heater of 2000 W to 2500 W is ideal. This range provides sufficient heating power to efficiently achieve the desired temperature. These heaters are a good choice for living rooms or larger bedrooms, where the space is larger but not too large to require more power.

In the case of larger rooms or open spaces, you may need a heater with an even higher wattage, such as 3000W or more. In exceptionally large spaces or rooms with high ceilings, multiple heaters may be required to ensure even heating throughout the room. These areas tend to lose heat faster, so choosing the right wattage is important to maintain a comfortable temperature.

Are room heaters energy efficient?

Room heaters use electricity, and the amount depends on the type, size and use. Oil-filled heaters tend to be more energy efficient for long-term use because they retain heat for longer. Fan heaters and radiant heaters may use more power in short periods of time, but heat the room quickly. To save on electricity bills, it is advisable to use a room heater with an adjustable thermostat, a timer and an energy-saving mode. In addition, only use the heater when necessary and switch it off when the desired temperature has been reached.

How long does a room heater last and what maintenance is required?

The lifespan of your room heater can vary depending on the type and brand. For example, oil-filled heaters are known for their long lifespans, often lasting up to ten years, because there are fewer moving parts. On the other hand, fan heaters and ceramic heaters typically have a lifespan of about 5-7 years. To ensure that your heating system lasts as long as possible, regular maintenance is essential. Simple tasks such as cleaning the filters, checking the heating elements and looking for signs of wear can significantly improve performance and safety. With the right care, your heater can keep you warm for years to come.

Factors to consider before buying the best room heater

Type of heating: Choose between fan heaters, oil-filled radiators, convection heaters and halogen heaters based on your needs (speed, efficiency, noise, etc.).
Heating power: Choose a heater with the correct wattage for the size of the room. A heater with a higher wattage works better for larger rooms.
Energy Efficiency: Look for heaters that are energy efficient to reduce electric bills. Oil-filled heaters and convection heaters tend to be more energy efficient over time.
Heating speed: Some heaters heat up quickly (e.g. fan heaters), while others, such as oil-filled heaters, take longer but provide long-lasting heat.
Safety features: Make sure the heater has safety features such as overheating protection, tip-over switches, and a cool-to-the-touch exterior to prevent accidents.
Noise levels: Choose a quiet heater for bedrooms or quieter areas if noise is a problem, such as oil-filled heaters or convector heaters.
Portability: Consider how easy it is to move the heater, especially in smaller rooms or if you need to move it between rooms.
Cost: Consider your budget. Fan heaters tend to be cheaper, while oil-filled heaters and ceramic heaters may be slightly more expensive but offer better value in the long run.
