As temperatures start to drop, staying warm and comfortable becomes a priority. A space heater can be the perfect solution to quickly and efficiently heat any room, whether it’s your living area, bedroom, or office. With the wide variety of models available, finding the right one for your needs can feel overwhelming.
Each space heater has its own set of features, ranging from different heating technologies to safety options and energy efficiency ratings. Choosing the right one depends on factors like the size of the room, how much energy you’d like to save, and specific safety concerns for households with children or pets.
In this article, we’ll break down everything you need to know about space heaters, including the key types, their benefits, and important features to look for when making your decision. Let’s get started.
Space heaters are a great way to add extra warmth to specific areas of your home without heating the entire house. They’re ideal for cold spots like bedrooms, offices, or basements where central heating might not reach effectively. Here are a few reasons why having a space heater can be beneficial:
Energy Savings: Instead of turning up the heat for your entire home, you can use a space heater to focus warmth in the room you’re using. This targeted heating can reduce your energy bills, especially if you’re only heating smaller spaces.
Personal Comfort: If you tend to feel colder than others in your household, a space heater allows you to create a cozy zone just for yourself. It’s also perfect for those chilly mornings when you want to warm up one room before getting out of bed or starting your day.
Portable Warmth: Unlike central heating systems, space heaters are easy to move from room to room. This makes them a flexible option for keeping your home comfortable throughout the day—whether you’re working from your home office or relaxing in the living room.
Supplemental Heating: Sometimes, your central heating system might not be enough, especially during the coldest months. A space heater can supplement your main heating system, adding that extra boost to keep things cozy.
Quick Heat: When you need warmth fast, a space heater delivers. Many models can quickly heat a room in just a few minutes, which is perfect for those moments when you need a quick burst of warmth.
Overall, space heaters offer a practical, flexible, and energy-efficient way to ensure your home stays warm and comfortable throughout the colder months.
There are several types of space heaters available, each designed with a specific heating method to suit different needs. Here’s a breakdown of the most common types and what makes them unique:
Ceramic heaters are popular for their quick heating abilities. They use ceramic plates that heat up as electricity passes through them. A fan usually helps to distribute the warm air throughout the room, making them ideal for small to medium-sized spaces.
Infrared heaters work differently from other types because they heat objects and people directly, instead of warming the air. Think of it like standing under the sun—it provides instant warmth without waiting for the room to heat up.
Oil-filled radiators are one of the most efficient types of space heaters. They use electricity to heat oil contained within the heater’s fins. The oil retains heat well, which means the heater continues to radiate warmth even after it’s turned off. They are perfect for maintaining steady heat over long periods.
Fan heaters are another popular option because they provide quick heat. These heaters work by blowing air over a heating element, which is then distributed throughout the room. They are usually small and easy to move, making them great for personal use.
Panel heaters are wall-mounted or free-standing units that are great for permanent heating solutions in rooms where you need warmth but don’t want a bulky heater taking up space. They can be either convection (heating the air) or infrared (heating objects).
Each type of space heater has its strengths, so it’s important to consider your space size, heating preferences, and noise tolerance before making a decision. Knowing these key differences can help you pick the right heater for your home’s specific needs.
When choosing a space heater, energy efficiency is a crucial factor, especially if you plan on using it regularly. An energy-efficient heater can help keep your electricity bills in check while still providing the warmth you need. Here’s a closer look at what you should consider when it comes to energy efficiency:
Most space heaters operate between 750 watts and 1,500 watts, with higher wattage providing more heat. However, more power also means more energy consumption. It’s important to choose a heater with the right wattage for the space you want to heat.
Using a lower-wattage heater in a small room can save a lot of energy without sacrificing warmth.
Many modern space heaters come with an adjustable thermostat feature, allowing you to set a specific temperature. This is one of the best ways to improve energy efficiency because the heater will turn on and off to maintain your chosen temperature, rather than running continuously.
Many space heaters now come with an energy-saving mode or eco mode, which automatically adjusts the power output based on the room’s temperature. This smart feature ensures the heater uses just the right amount of energy to maintain warmth.
Using a space heater with a built-in timer allows you to control when the heater turns on or off, even if you’re not in the room. This feature is ideal if you only need heat for a few hours, such as warming up a bedroom before bedtime or a living room in the morning.
Different types of heaters have varying levels of energy efficiency based on how they operate:
The efficiency of your space heater also depends on the size of the room and how well insulated it is. Heating a small, well-insulated room will always be more efficient than trying to warm a large, drafty space.
By focusing on energy-efficient features like thermostats, energy-saving modes, and choosing the right heater for your space, you can enjoy a warm home without a big spike in your energy bills. Investing in a well-insulated room and using your heater wisely will also maximize its efficiency, helping you stay comfortable and cost-effective all winter long.
Safety is one of the most important factors to consider when buying a space heater. Because space heaters generate heat, they come with certain risks if not used properly. Thankfully, many modern heaters are equipped with safety features to help minimize these risks. Let’s take a closer look at the key safety features you should look for in a space heater:
Tip-over protection is a must-have feature, especially if you have kids or pets in the house. If the heater is accidentally knocked over, this safety feature automatically shuts the unit off to prevent it from overheating or causing a fire.
Overheat protection is designed to prevent the heater from running too long or getting too hot. This feature kicks in when the heater’s internal temperature reaches unsafe levels, automatically shutting it off to prevent overheating.
Many modern space heaters come with cool-to-touch exteriors, which means the outer surface of the heater remains cool even while it’s operating. This feature is especially important if the heater is placed in high-traffic areas or where it could be accidentally touched by children or pets.
Heaters with automatic shut-off timers allow you to set a specific operating time, so the heater turns off after a designated period. This feature is great for peace of mind if you tend to forget to turn off your heater when leaving the room or going to bed.
A thermal cut-off switch is another feature that protects against overheating. It acts as a backup to the overheat protection system, cutting off the power if the heater’s internal components become too hot.
Some space heaters come with a child lock feature, which disables the controls on the heater. This prevents curious little ones from changing the settings or turning the heater on or off when they shouldn’t.
When buying a space heater, always check for safety certifications like UL (Underwriters Laboratories) or ETL (Intertek). These certifications mean the heater has been tested to meet recognized safety standards.
By choosing a space heater with these safety features, you can significantly reduce the risks of accidents or fires, ensuring a warm and safe environment in your home. Always make sure to follow the manufacturer’s instructions for safe use.
When choosing a space heater, noise level is an important factor to consider, especially if you plan to use it in quiet environments like bedrooms or offices. Different types of heaters produce varying levels of noise depending on their heating technology. Let’s take a closer look at how different types of space heaters rank when it comes to noise:
Ceramic heaters that come with a built-in fan tend to be noisier than other types. The fan helps to distribute the heat evenly throughout the room but can generate a noticeable hum or whirring sound while running. If you’re sensitive to noise, this may not be the best option for quiet spaces.
Infrared heaters are among the quietest space heaters available because they don’t rely on fans to distribute heat. They work by emitting infrared radiation that heats up objects and people directly. This makes them an ideal choice for environments where silence is key.
Oil-filled radiators are another type of heater known for being extremely quiet. These heaters don’t have fans and instead use heated oil to radiate warmth throughout the room. They may emit occasional clicking sounds as the heater cycles on and off, but these noises are generally minimal.
Fan heaters are designed to blow warm air into the room using an internal fan, which means they can be noisier compared to other heater types. While they are effective at providing quick bursts of heat, they often produce a constant humming or whirring sound, which can be distracting in quiet environments.
Panel heaters, whether mounted on the wall or free-standing, are generally very quiet. They use convection or radiant heating methods, which don’t require fans to circulate heat. As a result, they are ideal for rooms where you want silent warmth.
If noise is a big concern for you, your best options are infrared heaters, oil-filled radiators, or panel heaters, all of which offer minimal to no sound during operation. On the other hand, if speed and powerful heat are more important than silence, ceramic or fan-based heaters may be a better fit. Balance your need for warmth with the noise tolerance of the space you’re heating, and you’ll be sure to find the right option.
When it comes to space heaters, portability can be a key factor in making your home heating more convenient. If you need to move the heater from room to room or take it with you for different tasks, a portable heater can be a great solution. Let’s explore what makes a space heater portable and how to choose the best one based on your needs:
One of the most obvious factors that impact portability is the size and weight of the heater. Smaller, lightweight heaters are easier to move around and are perfect if you need to heat different areas of your home throughout the day. Fan heaters and ceramic heaters tend to be more compact and lightweight, making them easy to carry.
Many portable heaters come equipped with built-in handles or wheels to make transportation even easier. Oil-filled radiators, for example, are often heavier but come with caster wheels, allowing you to roll them from place to place without much effort. If you’re looking for portability in larger or heavier models, wheels are a big plus.
An often overlooked aspect of portability is the length of the power cord. A longer cord gives you more flexibility to place the heater exactly where you need it, even if the power outlet is far away. This is particularly useful in spaces where outlets are limited, like basements or garages.
A portable space heater is especially useful if you want to warm up different rooms at different times. Instead of buying multiple heaters for each room, you can invest in one high-quality portable heater and move it around as needed. This can save you money and reduce clutter, while still keeping your home comfortable.
If you’re using your heater only in the winter months, consider how easy it will be to store when not in use. Portable heaters with compact designs or models that have retractable cords are easier to store in closets or cabinets when they’re not needed.
If portability is a top priority for you, look for features like lightweight designs, handles, and wheels to make moving the heater from room to room easier. Whether you’re looking for something small and compact for a bedroom or a larger model for multi-room use, there’s a portable heater that fits your needs. Keep portability in mind to ensure your heater is as flexible as your lifestyle.
