If you’re living or working in a space that’s uncomfortably cold most of the time, the simplest answer, short of moving, is a small space heater. These little home appliances can fit on a desk surface to keep fingers warm while typing or can be tucked underneath to heat up your toes. In fact, you can bring them pretty much anywhere you need a little personal heating source, whether it’s by the couch, in a cold bedroom, at a small studio — you get the idea.
What Are the Best Small Space Heater?
Aside from size and ease of use, there are just one or two safety and convenience considerations we keep in mind when choosing a good piece of equipment.
Temperature Settings: At their most basic, a space heater has just one button to turn it on or off. Better heaters offer a variety of temperature and strength settings so you can adjust to whatever feels most comfortable to you.
Safety Features: To prevent accidental fires and overheating, basic safety features are essential in any small heater. This includes things like automatic shutoff after a certain amount of time or when the heater is picked up or knocked over.
Power: You may want to think about how much space the heater can warm up on its highest setting. If you only need it for one person, this may not be a huge consideration, but consider the size of the area or room you’re using it when looking for your next space heater.

3 Best small aquarium heaters for tiny tanks 1
One of the biggest complaints with small tanks is their lack of room. By the time you set up your decorations, such as gravel, plants and rocks, there isn’t a lot of room for much else – especially not a heater.
And before you ask, no, you cannot skip buying a heater.
at a glance: our top picks for small aquarium heaters
- for 1 to 2.5-gallon: FREESEA Aquarium Heater
- for 2.6 to 5-gallon: Hydor Submersible Glass Aquarium Heater
- for 6 to 10-gallon: Cobalt Aquatics Flat Neo-Therm Heater with Adjustable Thermostat
You see, rapidly rising and falling temperatures cause your fish stress, which can soon lead to death. And, temperatures change much more quickly in a small tank than in a large one.
Besides, tropical fish like betta need warm water to survive.
It is for this reason that a heater is essential to your tiny tank, no matter how cramped it may be.
FishLab tested 20 of the slimmest and most compact aquarium heaters across seven different tanks ranging from 1 to 10 gallons, to answer one question:
Which heater is best for your tiny tank?
Want the answer? Read on!
The limitations of small aquarium heaters
By far, the most common complaint I hear about small aquarium heaters is…
“My heater doesn’t work. The water is still too cold!”
More often than not, the problem is that they are using the wrong-sized heater for their tank.
how to choose the right size of heater
The following three conditions determine the correct-sized heater for you:
- The size of your tank,
- Your room temperature, and
- The temperature you want to raise your aquarium water to.
The power of an aquarium heater is measured in watts (W). The more watts, the more powerful the heater. A 20-watt heater, for example, is twice as powerful as a 10-watt one. The bigger your aquarium, the more watts you need to heat it.
The following table shows the heater wattage you need in order to heat a tank up to 10˚F higher than your room temperature.
If your heater cannot warm your tank within 7 hours, it’s probably too small.
Types of small aquarium heaters
First, let’s cover the two different types of heaters you can choose from…
1. Preset aquarium heaters
Ordinarily, preset heaters have been manufactured to reach a specific temperature – typically 78˚F (26˚C). Once this temperature is reached, the heater automatically shuts off and won’t turn on again until the temperature drops.
However, the majority of the preset heaters designed specifically for small tanks operate a little differently – they are “always on” and never shut off.
Do you have fish that prefer cooler or warmer water? Tough luck! You cannot change it – you are at the mercy of your heater. You don’t have to go far to find horror stories of preset heaters killing fish.
Always-on heaters don’t regulate the temperature. If the temperature of your room increases, say on a hot summer day, then using these heaters will also increase the temperature of your tank – which may be too hot for your fish.
However, you can get around this with the use of an aquarium temperature controller. This nifty device shuts your heater off if your water becomes too hot and turns it back on once the water cools – keeping your fish safe.
The number one advantage of preset heaters is their size. Without the need for a thermostat, manufacturers have been able to create some impossibly slim and small aquarium heaters.
I generally don’t recommend “always-on” preset heaters. But if you have a small fishbowl with less than 3 gallons of water, a compact preset heater will leave you with more space for your critters or decorations.
For the rest of you? The next aquarium heater is the only one you should consider…
2. Adjustable aquarium heaters
These aquarium heaters allow you to select a temperature within a defined range, generally between 66-96˚F (19-36˚C).
Once this temperature is reached, the heater shuts off and won’t start again until the temperature drops below this setting.
While adjustable heaters are often larger than preset heaters, they have the advantage of allowing you to regulate the water temperature according to the fish you keep.
Use the thermostat to make the water hotter in winter and cooler in summer – so your fish don’t cook or freeze.
Now, let’s look closer at what FishLab found to be the best aquarium heaters for small-sized tanks…
Best small heater for 1 to 2.
The FREESEA Aquarium Submersible Heater is one of the best small aquarium heaters you can get today. In spite of its simple design, the product ensures maximum functionality throughout the day.
The FREESEA Aquarium Submersible Heater comes with a simple design that you can submerge in the water. As soon as you turn on the system, it will show you the real-time temperature. Designed for a water tank of 1 to 10 gallons, the system can maintain a temperature range of 59 degrees to 94 degrees Fahrenheit.
You can use a couple of modes to control the internal water temperature. The temperature control unit has to be outside the water, and you can set the desired temperature. Once the internal temperature has gotten to a point, the system will adjust its performance to maintain the temperature.
The entire system, including the temperature control chip, is entirely waterproof with an IPX8 rating. So, you would not have trouble using it in the long term. In addition, because the system comes with a thermostat, you do not have to purchase a third-party thermometer.
You should provide enough time for your fish to get used to the FREESEA Aquarium Submersible Heater. Its heating system attracts fish and may lead to some casualties. However, as long as you watch this aspect, the entire water heater is a superb choice.
● Easy to install
● External control switch
● Constant temperature control
● Smart circuit controls
● It can be a fish trap in some cases
● It cannot be used with big tanks
I used an accurate aquarium thermometer to test and can confirm the heater worked as advertised. Speaking of which, if you need a good aquarium thermometer, FishLab reviewed those here.
Best small aquarium heater for 2.6 to 5-gallon tanks
The Hydor Theo is an adjustable aquarium heater. Most importantly, it’s the smallest adjustable heater on the market.
Want your water hotter or colder to suit your specific fish? Or, maybe you want to turn the heater down during summer. Simply twist the dial on the top of the heater to select a temperature between 67-91˚F (19-33˚C).
Best of all, when tested against our calibrated testing equipment, we found that the heater was within 1˚F of the selected setting.
As you expect, the heater shuts down when the water exceeds the set temperature and switches back on when the temperature drops. An indicator light on the side of the heater lets you know what it’s doing.
Both the 25W and 50W models are 7-inches (18-cm) long, making them perfect for heating smaller tanks, up to 5 gallons.
And yes, the heater is fully submersible. Check it out in a 5-gallon Aqueon Minibow…
Or, depending on what you have in your tank, you can mount the heater horizontally.
For the most space-efficient installation, I recommend wedging the heater in the corner of your tank like this…
Best small aquarium heater for 6 to 10-gallon tanks
Good news! Once you reach this size, you can use almost any heater you want.
But when it comes to precision heating, size and reliability, there is only one aquarium heater you should pick…
Out of all the aquarium heaters we reviewed, the Cobalt Neotherm was the clear winner. We don’t just recommend it as the best aquarium heater for small tanks, FishLab recommends it as the best aquarium heater for all tanks!
Accurate to ± 0.5°F, you can be confident that whatever temperature you set is what it will heat to. No other heater we tested offered this degree of precision.
The Cobalt Neotherm is the heater I currently use on most of my tanks. At the time of writing this, the oldest one has been going strong for over 6 years.
See the heater in a 10-gallon aquarium…
Note: The 50W and 75W Cobalt Neotherm models are generally the cheapest.

What about a runner-up?
I would recommend the Aqueon Pro as the runner-up, but they are currently in the middle of updating their heaters. The current models are pretty great.
Unfortunately, given Aqueon’s track record with other aquarium products we have tested, such as their air pump, gravel vacuum and water changer, there is no guarantee the replacements will be as good. I will comment once the new models are released, and we have tested them.

Even smaller aquarium heaters
This section covers the smallest of the small aquarium heaters.
To reduce the size, these heaters are stripped of virtually every feature. Yep, they are little more than a heating element and a cover.
These heaters are “always-on,” and the only safeguard is you choosing the correct size for your tank.
Let me make it clear that the heaters I listed earlier in the guide are superior in every way.
Due to the lack of safety features found on the following heaters, I don’t recommend them.
The only reason you would choose these heaters is if you value size above everything else. And if that’s the case, you’ll be impressed by just how small these itty-bitty heaters are.
You won’t find anything smaller than these tiny heaters.
First up, we have the Hydor Slim. The smallest aquarium heater for fishbowls…
This circular heater is designed to sit in the flat section at the bottom of your fishbowl.
It’s impressive just how slim this heater is. Cover it with gravel, and you hardly notice it’s there…
Add a fake plant on top to hide the power cord, and you are done.
No other fishbowl heater can be so easily hidden.
Next up, you have the smallest aquarium heater currently available…
At 3 inches long, this heater is impossibly small. Here it is compared to a quarter…
And here it is in a 1-gallon tank…
Here is one more option for small square or rectangular tanks…
The Marina Betta is designed for the smallest of tanks, up to 1.5 gallons. And as expected, it is pint-sized…
And here it is in a 1-gallon tank:
If you made it this far, then you should have found the perfect small heater for your aquarium.
Just to recap:
The best small heaters for tiny aquariums.
|Freesea Aquarium||1 – 2.5 gallons|
|Hydor Theo||2.5 – 5 gallons|
|Cobalt Neotherm||5 – 10 gallons|
While a tiny aquarium heater is tempting, the smallest lack essential features found in my slightly larger recommendations – these hit the sweet spot between size and safety.

types, which is better, pros and cons
In the off-season, many people need sources of additional heat for houses and apartments. RBC-Nedvizhimost understands what heaters are and how they differ from each other
Still from the movie Girls
Today, customers have a wide choice of various equipment for heating small spaces, unheated premises and entire houses. Heaters can be very simple or equipped with the latest technology, they differ from each other in performance and noise level, size and purpose. Choosing the right heater is quite simple if you know what to focus on.

- Fan heater
- Which heater to choose: 7 tips
What is a heater
Heater – a household appliance for space heating. Such devices can be divided into several types: some are more suitable for heating country houses or technical premises, others will be an ideal solution for small apartments or individual rooms.
The world’s first electric heater was invented in the 1930s by Frenchman Jacques Noirot. The invention was a fan that drove air to a hot spiral connected to the mains. It was this mechanism that became the prototype of modern heaters. But today’s models are quite far ahead of their prototype.
1. Infrared heater
Unlike other types of devices, this device does not heat the air, but objects around: the floor, walls, paintings, cabinets and even people. Such a device is ideal for open spaces, but if there are many partitions in the room, it will not cope well, since IR rays cannot go around obstacles.
Infrared heaters are light (a spiral is heated in a glass tube), convective (in addition to the heating element, it heats the surface of the device itself) and film (the heating element is a foil film).
- Quickly and efficiently heats objects that are hit by its rays.
- Serves as a source of bright light, can be used instead of a conventional lamp.
- Economy. Since the appliance does not need to heat the entire room, it operates directly, with 500W of power enough to get the job done and use less electricity.
- Does not create drafts. Unlike convector devices, the operation of which leads to the constant movement of cold and warm air streams (and dust along with them), IR heaters hit exactly the target at which the rays are directed.
- If necessary, only a part of the room can be heated.
- Suitable for outdoor heating – on the veranda, in the gazebo or on the terrace.
- Simple and durable construction requires little maintenance and will last a long time.
- Eco-friendly, no emissions.
- Easy installation. Can be placed on the floor, wall or ceiling, and at any angle.
- High temperature models may cause a fire if not handled carefully.
- The temperature drops rapidly after switching off the device.
- Uneven heating.
- In case of long-term exposure to IR rays, the skin becomes very dry.
- May be hazardous to children and pets. The flask and reflector of the device are very hot, you can burn yourself on them.
- Bright light from a bedroom heater can make it difficult to sleep.

2. Oil heater
In these appliances, an electric coil heats a special mineral oil. The more sections the heater has, the more powerful it is.
The surface of the oil heater can reach up to 120 °C
- Low cost.
- Easy to maintain.
- Continuous space heating.
- No foreign odors.
- Long heat retention after switching off.
- Environmentally friendly.
- Low noise level.
- Long warm-up.
- Burn easily.
- Large size and low mobility.
- Dry air in the room.

3. Convector heater
The principle of operation of a convector heater is quite simple: the air passes through the heater and rises, displacing cold layers. The surface of the device is heated up to 90 °C.
Film convector heaters are usually hung on the wall. Such devices are good for part of the room. If you need to heat a large room, it is better to place such an apparatus above a source of draft – that is, above a door or window.
- Does not dry out the air.
- Suitable for bathrooms and nurseries.
- Does not cause unpleasant odors.
- Relatively high power consumption.
- Significant temperature difference in different parts of the room.
- Slow warm up.
- Spread of dust.
4. Fan heater
The main task of a fan heater is to heat up the room quickly, with the help of a heater enclosed in a plastic or metal case and a fan that circulates air. On the market, you can find heat guns for warehouses, and mini-fans for the desktop. Many devices are equipped with a rotary mechanism, allow you to switch power and temperature, and provide for remote control.
- Heats up the room efficiently and quickly.
- High energy consumption, not suitable for continuous operation.
- High power (up to 5 kW) can be a test for old wiring.
- Dries the air.
- Spreads an unpleasant smell of burnt dust.

5. Monolithic heater
Due to their design, monolithic heaters combine the principle of operation of two types of devices: convection and infrared. They consist of pressed quartz sand (sealed body) with a heater inside – a nichrome coil. The design is simple, non-separable, but provides uniform heating of the room.
- High heat capacity, cools down more than two hours.
- Dust proof.
- Does not dry out the air.
- Bulky, limited mobility.
- Rough handling can cause burns.
- It is necessary to buy a thermostat.
6. Electric Heater
Electric heaters come in a variety of plug-in models. Basically, they heat part of the room, the pros and cons of each model are different and are determined by its configuration, power, noise level, the presence or absence of the ability to mount the device on the wall, etc. But there is one common main drawback: all these devices consume a lot of electricity and create an additional load on the wiring. In older buildings or country houses, this issue can be crucial.
7. Ceramic heater
This group of heaters includes convector and infrared heaters. In convector devices, a metal heat exchanger is covered with ceramics, through which air passes and heats up. In the device of infrared heaters, ceramic plates are used. In addition to the inherent advantages and disadvantages of each type, they have several common features.
- After switching off, it gives off heat for some time.
- Does not dry out the air.
- Noisy fan.
- Consumes a lot of electricity.
8. Gas heater
The main difference between all heaters of this type is that they run on natural or liquefied gas. The design includes a housing, a heat exchanger, a heater and a burner. Models are mobile and stationary, can be connected to the main network or run from cylinders. Convector and infrared heaters operate on gas.
Gas heaters are portable and stationary
Convector heater equipped with a chimney and a CO2 sensor. The IR heater on gas can be with a catalytic or ceramic panel. The ceramic heater heats up more and is more suitable for spacious rooms. In catalytic, the principle of operation is based on the interaction of gas with a catalyst: heat is not due to combustion, but as a result of a chemical reaction.
- Economical fuel consumption.
- Many models that differ in size, power and installation options.
- Suitable for rooms without electricity.
- Efficient, quickly heats up the space.
- May cause fire if misused.
- For installation, it may be necessary to carry out additional work and extend the gas hose.
- Not recommended for use in areas with small children.
- Periodic preventive examinations required.
- The heated room needs to be ventilated frequently.
9. Halogen heater
Halogen heaters work on the same principle as infrared heaters: they heat surfaces, not the air. Inside the device is a lamp with a tungsten filament and gas inside, which emits heat rays.
- Heats up quickly.
- Economical, consumes less electricity.
- Doesn’t handle large spaces well.
- Bright light may irritate the eyes and interfere with sleep.
- The lamp inside the instrument is very fragile and may break frequently.
10. Micathermal Heater
The device works on the same principle as halogen and infrared heaters. The heating element – a nickel mesh inside mica plates – emits radiation that penetrates the surrounding objects, the floor and walls, turning them into sources of secondary thermal radiation.
- Sensitive to overheating.
- Low power.
- Heats up unevenly, so that islands of cold can form in places.
Which heater to choose: 7 tips
A wide range makes it difficult to choose. A small list of tips will help you accurately determine which type of device you need. Here is an algorithm for choosing a suitable model.
1. Measure the area of the room
The output of the heater depends on this. For 10 sq. m enough 1 kW, and in order to warm up 25 square meters. m, it will take 2.5 kW. For each model, a comfortable and maximum heating area is usually indicated.
2. Determine available types of power supply
In an apartment with electricity, the choice is wider than in a private house without communications or with old wiring. On the other hand, not every room will be able to install a gas heater.
3. Select the purpose of the heater
If you are looking for equipment that can quickly and briefly heat a large room, then a heat gun is ideal. In order to sit warmly on the veranda from time to time, an IR heater is suitable. If the appliance is to be used for a long time, an oil heater is a good choice.
Infrared heater heats objects, not air, so the chairs and benches on the terrace will quickly become warm
4. Consider the specifics of the room
Children’s rooms have special safety requirements, as do rooms with high humidity, such as the bathroom. Most heaters are equipped with protection against overheating and falling, but many can burn themselves. There are models with a waterproof case and those that are attached to walls and ceilings, where small children cannot reach them.
Noise levels can become critical in a bedroom or office. Usually it is indicated in the documentation for the device. Some of the quietest heaters are infrared, oil and convector. However, it is important to take into account all the parameters in the complex. For example, a quiet infrared heater will also provide a bright light that will prevent the baby from falling asleep.
5. Draw financial boundaries
How much are you willing to spend? This is not only about the price of the heater, but also about fuel consumption. So, there are energy-saving appliances and devices with high performance that will quickly heat a large room, but they will also consume a lot of electricity. You should pay attention to such a parameter as performance: for how much time what area and at what energy consumption the device will heat. This information can be found in the instructions or ask a consultant.
6. Find a place for the heater
This directly affects the requirements for the size and type of device mounting. The power of the heater does not always depend on the dimensions, and models of the same size may have different performance.
Consider additional requirements for functionality
Heaters differ in the type of control: mechanical and electronic. Some models may have an on-off timer, protection from dust or moisture, a night mode function, a delayed start, the ability to program several operating modes or even control the system remotely.

With the onset of the first frost, the house becomes uncomfortable and cold. This means that it’s time to visit the Eurostyle store in Penza in order to purchase a quality heater. In apartments, heaters are most often used as an additional source of heat at a time when the main heating cannot cope and it is chilly in the room.
Heaters for apartments and cottages must meet several requirements. First, they must be safe. This is perhaps the main selection criterion, especially if the family has small children. One of the key safety points is the presence of overheating protection – the equipment should automatically turn off when a critical temperature is reached. Secondly, the heater must be efficient and, it is highly desirable that it has the function of maintaining a given temperature regime. In addition to being convenient, it also saves electricity – the heater turns on and off, and does not work all the time.
There are a great variety of models on the market today, which differ in efficiency and quality characteristics. Among them are:
- fan heaters;
- oil coolers;
- electric convectors;
- infrared emitters.
Electric fan heaters
This appliance has a heating element and a fan. The fan drives air through the heating element, it heats up and carries heat into the room.
The advantage of this type of heater is an almost instantaneous start. After switching on, less than a minute passes and it starts to “drive” already warm air. The second positive point is the small size and weight, hence the high mobility. And the third plus is the low price. If you decide which heater is better to choose for quickly heating air in a small room, then a fan heater is perhaps unrivaled.
Electric convectors have a principle of operation similar to fan heaters – air passes through the heating element, heats up and spreads heat around the room. The difference is that the movement of air in convectors occurs due to the natural process of convection – the property of warm air to rise up and, in principle, fans are not needed for its movement. But the movement of air in such heaters is slow, and the cold room will warm up for a long time. To correct this shortcoming, fans are also built into the convectors, which, if necessary, activate the heating. Nevertheless, the main difference between convectors and fan heaters is that they can operate without a fan, that is, completely silent. At night, a very important quality.
This type of heater has been known for a long time. Has the tight case filled with technical oil. A heating element is immersed in oil. There may be several of them, they are usually turned on / off manually by turning the knob / switch.
These heaters are good for both home and garden. They are very reliable, rarely break, have a safe design and relatively low prices.
Many people prefer this type of heater, as they spread soft heat, even next to them there is no discomfort. Families with children also prefer such heaters – the design is safe, the body heats up to no more than 60 ° C, which is unpleasant when touched, but absolutely safe. Quiet operation is also a plus.
The main disadvantage of oil radiators is the low rate of space heating. While the oil heats up, the body warms up, a considerable period of time passes. Only then does the air begin to heat up. And then the process goes slowly – only due to natural convection, which usually leads to the fact that it is warm near the heater, a little further – cold.
