The list of necessary aquarium equipment includes an aquarium heater, which helps keep fish in a comfortable habitat. This is important for the good life, growth and health of the fish. There are several recommendations regarding the choice of such a device.

Do you need a heater in an aquarium?

To answer this question, it is necessary to consider the main functions of this device:

1. Heating water. Using the device, you can heat the liquid in the aquarium by only 3-5°C; you don’t need to think that it works like a boiler. It is necessary if the room is cold or if the aquarium contains tropical fish species.
2. Temperature stabilization. Many people are interested in whether it is possible to do without a heater in an aquarium, but it all depends on what kind of fish a person has chosen, since for many aquatic inhabitants a temperature fluctuation of even a couple of degrees is unacceptable, since the immune system suffers, and this can cause death. Most of all, such jumps are typical for aquariums small size, so in this case the heater will be a mandatory device.
3. An aquarium heater creates, albeit insignificant, movement of layers of water, which promotes mixing of the liquid, and this prevents stagnation.

Which aquarium heater to choose?

There are several classifications used for heating equipment. Each type has its own advantages and disadvantages, which should be taken into account in order to choose the most appropriate one for a particular case. suitable option. An aquarium water heater may have different designs, thanks to which it can be mounted in different parts vessel, providing the desired heating of the liquid.

Flow-through heater for aquarium

Devices of this type involve passing water through themselves. There is a special heating element inside, which heats the water as it passes through it. Flow heaters for an aquarium turn on automatically when liquid movement begins. Such a device must have high power. The disadvantages of this type include high energy consumption.

Submersible heater for aquarium

This option is more common, and it has several subtypes:

External heater for aquarium

In most cases, such a device is built into the system of an external remote filter, that is, the water that passes through it will not only be cleaned, but also heated. There is another option for an external heater, which is a heating pad made of rubberized material, which contains flexible heating elements. The water is heated through the glass bottom of the vessel. An external aquarium heater with a thermostat has a drawback - a lot of heat goes into the stand. Heating through the bottom provokes rapid growth bacteria.

Bottom heater for aquarium

In this case, heating cables are used, which are laid along the bottom before filling the soil. The main characteristics include:

1. Their main task is to ensure the movement of water flow in the soil, which helps prevent its acidification.
2. This aquarium heater with a thermostat helps to heat the bottom layer of water, which is always colder when in use. traditional options equipment.
3. It is recommended to use the bottom heating option as an additional option to any of the previously discussed devices.
4. The cable cannot be laid in a shallow one and it should account for about 1/3 of the total power.

How to choose a heater for an aquarium?

There are several important points, which you should pay attention to when purchasing such equipment:

1. The aquarium heater must have a thermostat to maintain a constant water temperature. When the required value is reached, the device will turn off and start working again when the water cools down. The thermostat can be immersed in water or placed outside the aquarium.
2. Some heaters have additional features, for example, forced emergency shutdown in the absence of water.
3. When figuring out how to choose a heater for an aquarium, it is worth noting that different devices can regulate temperatures differently. In some models you can set a range, and in others a specific value that will be constantly maintained. When choosing, it is recommended to pay attention to the adjustment interval.
4. A heater for or a vessel of any other shape may have different area heating This information can be read in the instructions that came with the device.
5. Pay attention to the package; if necessary, the kit should include fasteners or a protective cover that will prevent damage to fragile parts.
6. If you need to select a heater for sea ​​water, then be sure to check whether the salt will damage the parts of the selected device.

Aquarium heater power

One of the most important indicators One thing that should definitely be taken into account when choosing such equipment is power. Its value is determined taking into account the volume of the selected vessel. In most cases, a water heater for an aquarium with and without a thermostat should have 1-1.5 watts per 1 liter of water. Experts recommend choosing devices with a small margin, that is, with a large power rating, in order to increase heating if something happens, for example, if the room is too cold.

Which aquarium heater is best?

There are several manufacturers that offer similar devices that have earned respect among people. Many people are interested in which is the best heater to buy for an aquarium, but it is difficult to single out just one manufacturer, since it all depends on the requirements set by the buyer. It is worth noting that many aquarium manufacturers simultaneously produce additional equipment, among which there are heaters. In this case, it is better to choose all of the same brand.

Aquarium heater "Juwel"

Under this name you can purchase several devices of different capacities, so you can choose the option for your volume. Water heaters in the Juwel aquarium have the following characteristics:

1. The device has a built-in thermostat. In order to start using it, you just need to set the required temperature on the top of the heater and the value will be maintained in the specified range. The device will turn off when the required temperature is reached and turn on when the water cools down.
2. The aquarium heater has a standard mount suitable for all types of containers. If the device was purchased for Juwel aquariums, then it can be installed inside the housing of the built-in internal biological filter.

Aquarium heater "Tetra"

Among the equipment of this company, one can highlight the “TETRATEC HT 25W” device, which has a special temperature controller from 19 to 31°C.

1. Given the presence of a waterproof case and cover, the heater can be safely completely immersed in water.

How to install a heater in an aquarium?

The equipment for maintaining the required temperature is waterproof, so it can be installed in a vertical position (the adjustment handle must be above the water surface) and in a horizontal position (completely immersed in water). There are several nuances on how to install a heater in an aquarium:

1. Do not insert the equipment into sand or gravel as this may cause damage to the equipment.
2. Make sure that the water is always above the minimum immersion level. For this purpose, the device has a special mark on the body. Remember that the liquid level is constantly falling as evaporation occurs.
3. A heater for turtles in an aquarium or fish is in most cases attached to the wall using a bracket with two suction cups. Each equipment comes with detailed instructions.
4. The device should be mounted in a place where there is constant and uniform circulation of water.
5. After the heater is installed and filled with water, you must wait at least 15 minutes for the temperature of the bimetallic switch to equal the value of the liquid, and only then turn it on.

To maintain the normal functioning of your pet fish, you need to install a water heater. Its presence is mandatory. It does not depend on the room temperature. In this article we will try to answer the questions: how to choose the right water heater for an aquarium and how to install it.

What is a fish water heater?

Aquarium water heater- This is a special device for heating water. It helps provide a comfortable life for your fish. It is especially necessary for tropical species, where the water temperature should be at least 22 and no more than 30 degrees. It is often believed that an aquarium water heater is a simple and optional device. Although in importance it is equal to a water filter.

Previously, salt heaters were most often found. They functioned by passing electricity through the solution. But consumers had to independently regulate the level of saline liquid. Therefore, this type gradually became a thing of the past. At the moment, there are a large number of different devices for heating water in a fish house.

Types of water heaters

There are various devices for heating water in an aquarium. Basically, they can all be divided into four main types. Firstly, these are submersible models. They have several subtypes:

• Glass. The device body is shock-resistant and heat-resistant. It closes hermetically. It turns on and off automatically, while maintaining the set temperature.
• Plastic. Technically advanced heater compared to glass. It has compact dimensions, flat shape and LED signal.
• Model with titanium heating element. Can be used for any aquarium. Perfect for heating large volumes of water, for example, if you keep turtles rather than fish.
• Mini heaters. They are characterized by a flat design, which allows you to hide such a device even under the ground in an aquarium.

Secondly, it is available for sale for an aquarium. Mainly used for external filters, which allows you to leave more space in the aquarium itself. A vertical filter return hose is attached, which allows the heat to be distributed evenly. Thirdly, you can buy heating cables for heating water. They also provide a smooth supply of heat, pass along the bottom, and are attached using suction cups. Fourthly, it is possible to use They can be located under the aquarium. Provide smooth heat dissipation.

Making a water heater at home

Sometimes it is not possible to purchase even the simplest device for heating water. In this case, you should make a water heater for these purposes. There are many in various ways. Let's look at one of them step by step:

1. First you need to find a container that can withstand temperature changes and not burst. A regular glass medicine bottle may work. To check, place it in a container of water at room temperature, holding it with tweezers. Pour boiling water: if there is no damage, you can use such a container.
2. The heater may have one or more resistors connected in series. In this case there will be several of them. We prepare resistors for placement. You can make a kind of valve to prevent sand from getting outside the heating part.
3. If desired, you can solder the LED. It will signal that the heater is turned on.
4. We check whether the part responsible for heating is working. To do this, briefly plug in the device and check the temperature of the device. Place the resistors in the prepared container. Just fill it with sand or salt first.
5. We take a heat gun or glue for gluing aquariums. And we fill all the remaining space in the water heater.
6. For ease of fastening, you can purchase a suction cup. You just need to remove the hook from it.
7. Using fishing line, attach the suction cup to the heater.

That's all the steps that are required to self-made device for heating water in an aquarium. If you are not ready to take on the work yourself, it is better to contact specialty stores. The choice is very varied: you can buy one or another water heater for an aquarium. The price will vary depending on the type, power and manufacturer. Typically the cost varies from 800 to 2,000 rubles.

Popular brands of aquarium water heaters

When you come to a pet store to purchase a water heating device, the question arises: which model is better? As practice shows, purchase better water heater for aquariums from well-known and trusted brands. Leading manufacturers of such devices include products from Aquael, Eheim, Hagen, JBL, Tetra and Xilong.

Thus, the water heater has long conquered the markets, thanks to its good price-quality ratio. Mostly model range glass and plastic models are replenished. To optimize the use of such a device, the manufacturer suggests installing control buttons and a built-in electronic thermometer on plastic water heaters.

Eheim offers rod-shaped water heaters. Thanks to the glass body and full immersion The water is heated evenly. And a manufacturer of aquarium thermostats, such as Tetra, equips the device with an additional device. Such devices operate effectively in automatic mode.

How to choose the right water heater for you?

Let's say you decide to buy a water heater for an aquarium. How to choose it? It’s worth thinking about this in advance so that when you come to the store you already know exactly what you want. You should pay attention to the length, which should correspond to the water level in the container. Domestic heaters are all the same in length. If you purchase a model without automatic adjustment, you will have to calculate the temperature so that the water does not overheat in hot weather. Or you can install two such devices and turn off one of them in summer weather.

There are two opinions regarding the advisability of using an automatic temperature controller. Some believe that the liquid should change its thermal regime at different times of the day, as in its natural environment. Automation cannot provide this. Others, on the contrary, are sure that the aquarium should have a constant temperature.

In order not to make a mistake with the power, it is better to choose a more powerful water heater for an aquarium, with automatic adjustment. This way you can set the heating to turn off when a certain temperature is reached. In this case, be sure to pay attention to the quality and, accordingly, to the manufacturer.

What information will you find in the instructions for use for the water heater?

Besides technical characteristics device, which can be found in the instructions for use for the water heater, it is worth considering the recommendations for installing and adjusting the device. When you purchase a water heater for an aquarium, how to install it correctly will be described in the instructions. There you can find the following recommendations: The device can be completely submerged in water as it is waterproof. Do not install the heater in gravel or sand. Don't forget also about the decrease in water level due to evaporation. The water heater must be fixed in a place where constant and uniform circulation of water is ensured. Special attention give next moment: Only 15 minutes after lowering the device into the water can you connect it to the network.

Recommendations for adjustment are as follows: you need to wait until the heater warms up a little - to the temperature of the surrounding water. Only after this should it be turned on. When the indicator light is on, it means that the device is turned on. Further recommendations will be different depending on the presence or absence of automatic adjustment. Read the instructions before installing the device. Important Tips for a specific model will be indicated there.

Currently, there are a large number of people who like to keep exotic fish at home. And their maintenance and breeding cannot be done without special equipment. If you are going to have fish in an aquarium, you will definitely need a water heater. With its help it is possible to maintain optimal temperature V artificial reservoir for the full development and functioning of residents.

There is a wide variety of aquarium heaters:

1. Submersible. They are made from a variety of materials (plastic, titanium, glass). They have the shape of a flask with a heating element inserted inside it. This heater is partially or completely lowered into the aquatic environment.
2. . The thermostat of this type of device is located outside the aquarium. This saves interior space.
   
   
3. Heating cables. Perfect for heating round aquariums. The cable is placed underground. This ensures even heating of the water.
   
   
4. Mats for heating water. They should be installed under the aquarium. The water is heated through the bottom of the container.
   
   

Aquarium heater with thermostat

If the aquarium contains tropical fish, the water temperature should be an order of magnitude higher than the air temperature in the room. To maintain uniform water temperature during the day and night, aquarium heaters with a special thermostat are installed. The latter is equipped with a sensor. It heats the water to set temperature, after which it turns off the heating element. When the water temperature begins to drop, the thermostat turns the device back on.

The thermostat allows you to maintain a certain microclimate, and aquarists do not have to worry that their pets will die due to hypothermia or overheating of the water.

There are two types of thermostats:

Thermostats are also divided into:

1. Built-in. Together with heating element are located in a sealed housing, which is installed directly into the aquatic environment.
2. Remote. Installed outside the aquarium. They are connected using a wire to a temperature sensor located in the aquarium.

Using a water heater

The water heater should be used strictly according to the following rules:

1. The heater is turned on only after immersion in an aquatic environment.
2. Before immersing the heater in water, you need to unplug all electrical appliances.
3. Do not use damaged water heaters.
4. If the wire is damaged, the entire device should be replaced, not just the wire.
5. Use the water heater strictly for its intended purpose.

Installation

To maintain the desired microclimate in the aquatic environment, you need to know how to install a heater in an aquarium. The water heater can be installed in both horizontal and vertical positions. When installed vertically, the adjustment handle should be positioned above water level. When positioned horizontally, the heater is completely immersed in the aquatic environment.

The body of the heater is usually marked with water immersion level marks. The appliance must be installed so that the water is above the minimum immersion level. Over time, water evaporates, so you need to ensure that it does not fall below the minimum level.

The heater must not be installed in gravel or sand.

A bracket is installed under the heater head, which is attached to the wall of the aquarium using suction cups.

Please note that the installed device can only be turned on after 15-20 minutes. During this time, the temperature of the heater will become equal to the temperature of the water in the artificial reservoir. Only after this the device is connected to the network.

How to make it yourself

By making a device for heating an aquarium yourself, you can save significantly. The most ancient method of heating water was burning dry fuel. For this purpose, the aquarium was equipped with a small firebox. This method was used mainly when transporting fish, especially in winter time. We can only imagine how troublesome this was.

Over time, people learned to make an aquarium heater with their own hands - from a resistor. To do this, the latter was placed in the middle of an ordinary test tube. Due to the fact that air does not conduct heat well, the void between the resistor and the glass began to be filled with test tubes quartz sand. The neck of the test tube was filled with a waterproof compound. According to users, such a heater is quite capable.

There is also a salt heater for an aquarium. Let's look at how to make it yourself.

Before you start making a salt heater, you need to familiarize yourself with the safety rules for working with electrical appliances.

Required materials:

1. Plastic bottle.
2. Electrical cable with plug (can be removed from a broken device).
3. 2 copper rings 15-20 mm long.
4. Medium hard wire 20 cm long.

First of all, you need to make three holes in the bottle cap. We insert two wires with stripped edges into two holes. Copper rings are attached to the wires and flattened using a hammer. Under no circumstances should the ends of the wires touch each other, otherwise short circuit. You need to place weights in the bottle; for this you can use soil from an aquarium or stones.

Fill the bottle with water. The wires must be located below water level. The third hole in the plug is needed for condensation to escape. To attach a home-made heater, we use medium-hard wire. We wrap one end of the wire around the neck of the bottle, and bend the other in the shape of a hook and hang it on the wall of the aquarium. We place our device for heating water in the aquarium so that the neck is above the water level of the artificial reservoir.

Why is the heater stated to be salt? It's simple! To regulate its temperature you need to add it to the bottle. brine . To increase the temperature, add more solution. It is very important not to overdo it, otherwise you risk losing your pets due to boiling water. All manipulations with homemade water heater carry out only after disconnecting from the network.

For creation homemade heater Only take it if you have at least a little experience in electrical repair! Otherwise, it can be dangerous for both you and your pets.

For the full development and functioning of tropical fish, you simply cannot do without aquarium heater. It doesn’t matter whether you bought it in a store or decided to make it yourself, the main thing is to follow safety precautions when working with it.

The beauty of an aquarium depends not only on its choice and design, but also on how colorful its inhabitants are. It is useful to remember that the most colorful and unusual aquatic inhabitants live in tropical and equatorial waters. And their habitats are distinguished not only by their abundance various types and palm trees on the banks, but also because environment Such creatures are noticeably warmer than our everyday life, even at the height of summer. To create ideal conditions For your charming pets, the water in the aquarium must not only be purified and oxygenated, but also heated. This task is performed special device- aquarium heater.

Aquarium heater: how does it work?

Setting up a water heater for an aquarium is not difficult. His main element- a special wire that heats up under the influence of electricity. To make its use safe, the wire itself is located on a ceramic core, and is protected from contact with water by an outer casing made of glass or plastic.

If glass is chosen for the body, it is usually heat resistant and is also closed with a special lid that ensures tightness. The cover is also used to place all the control elements of the device.

Plastic models are compact and the price is slightly higher. But this is more than justified: such a heater not only looks stylish thanks to a body made of unbreakable plastic, but is also more advanced from a technical point of view.

When choosing a heater for an aquarium, you need to remember that the larger the volume of water, the more powerful the device you need to buy - otherwise it simply will not cope with its task.

Aquarium heater: how to monitor the temperature?

Temperature accuracy – important element long and comfortable life every inhabitant of the aquarium water world. However, monitoring your temperature on your own is not only tedious, but often impossible. In order not to waste your time and attention, you need to purchase an aquarium heater (heater) with a thermostat.

Heaters of this type are equipped with a special sensor that constantly monitors the water temperature. As long as this temperature is within the range useful for pets, the aquarium heater works quietly and creates a cozy environment for them. But as soon as the temperature exceeds the limit set by the owner, the device detects this and turns off, allowing the water to cool to the desired level.

Thermostats can be mechanical or electronic. The most common are mechanical ones - they are distinguished by high level reliability, a little more low prices and stable operation. However, their work requires periodic inspection– they can distort the readings by several degrees, and you need to check them with a separate thermometer. Electronic models are more accurate, so they have a higher price, but they are also a little less reliable.

In addition, the thermostat with which the aquarium heater is equipped can be remote or built-in. The remote one is located mostly outside the aquarium - only the temperature sensor is immersed in the water. However, it did not become widespread, since the built-in models turned out to be much more practical and convenient. They are assembled in a single housing with a heating element, becoming compact and featuring an advantageous design in the form glass flask elongated shape.

One of the most important factors safe maintenance aquarium fish is the water temperature, sometimes up to +27 °C. Without human intervention, it is almost impossible to provide the necessary parameters. Aquarium heaters are used for this, often with a thermostat. We will talk about their types and methods of use in this article.

Briefly about the purpose

The water in the aquarium can cool down in a few minutes. This is especially true for the cold season, when the temperature of residential premises depends on the weather and the conscientiousness of the stokers.

Did you know? The aquarium, made of gold, costs $5 million and is called the Golden Dragon.

There are many more factors that affect temperature that a novice aquarist may not even be aware of. For example:

• warmth from lighting fixtures and the distance from them containers;
• design: shape, volume, is there a lid, a gasket under the container, the presence of an internal volumetric background, is it located on a stand;
• is there a flow system from the water supply;
• number of water changes.

Therefore, you cannot do without heating the water in the aquarium. Heaters are used for this purpose.

Species

Aquarium heaters are divided into three types based on location.

1. Remote. Their advantages:

• are not contaminated by waste products of the inhabitants;
• increased service life;
• relatively cheap.

2. Containers built directly into the body, complete with heating element.

3. Submersibles look like a cylinder that is lowered into the water. The body is made from:

• plastics;
• glass;
• titanium.

And now more about each type of water heater in an aquarium.

Heaters

The simplest device - water heater in an aquarium without a thermostat. It is a glass or metal tube with a sealed inside nichrome thread. According to the principle of operation, it vaguely resembles the well-known boiler. In Soviet times, during the era of total shortages, it was the boiler that was used as a replacement for the heater. Even now, experienced fish lovers do not disdain this primitive device - in a hopeless situation, of course.

You need to very clearly grasp the moment when the boiler needs to be removed, so as not to end up with fish soup made from precious fish. Some craftsmen connect a boiler with temperature sensors. However modern market aquarium equipment provides a lot of options for ensuring such indicators as temperature.

Electromechanical thermostats

An improved mechanical heater is a metal or glass tube filled with a heater and thermostat, hermetically sealed. Thermostat- bimetallic plate. The property of metals to expand when heated ensures automatic switching on and off.

This device is reliable in operation, but sometimes distorts the indicators. To prevent troubles, measure the water temperature with a regular thermometer.

Electronic thermostats

It looks like a tube. Inside there is an electronic “filling” that provides functions. Such a thermostat has capabilities that Soviet aquarists could see only in a dream or in Western European specialty stores, if they managed to get abroad.

The advantages include:

• high accuracy (up to 0.1°C);
• presence of an electronic scoreboard;
• sound alarm when overheating.

Flaws:

• high cost;
• unreliability.

Did you know? The first aquarium was created in England in the 19th century.

Heating cables

They are a long elastic tube with a heating element, which is installed in the soil of the container.

Advantages:

• the entire mass of water is heated evenly;
• additional circulation is created;
• the aesthetic component wins;
• very useful for plants planted in an aquarium.

Flaws:

• when replacing faulty cables, you have to disturb the entire interior;
• The ecosystem design has limitations - heavy stones cannot be used, which can squeeze or damage the heating system.

Heating mats

Rugs, or heating mats, placed under the container. The operating principle is the same as heated floors, water mattresses, heating pads.

Advantages:

• water and soil are evenly heated from below, which is extremely beneficial for plants;
• cold layers do not stagnate at the bottom, the environment in the entire aquarium is the same temperature.

The disadvantages include inconvenient installation and replacement - you have to remove the aquarium. If it is large, then it becomes clear that this is a whole undertaking that cannot be done without help.

Flow thermostats

This device is mounted vertically on the return hose. external filter. Appreciated by fans. It provides:

• interior improvement;
• stable flow of warm water.

Flaws:

• used only in large volumes;
• There are no low power devices on sale.

Thermofilters

Thermofilter- a device built into external system equipment.

Important! The entire life support system in the aquarium depends on the smooth operation of this device.

Advantages:

• has a digital display;
• reliable in operation;
• heating accuracy is high;
• does not spoil the design.

How to make a choice?

To ensure optimal temperature regime residents will have to resolve the issue - how to choose a heater for an aquarium.

You should be guided by a number of rules that have been developed by generations of aquarists and which are successfully applied to this day. Experienced amateurs advise:

• buy an aquarium heater with an automatic thermostat in one housing and with more power than needed in terms of volume;
• do not save when purchasing;
• buy only branded products;
• after purchase in manual mode, use a thermometer to check the correct settings of the thermostat;
• pay attention to the safety of the device - it must have good electrical insulation;
• choose a heater with a grill to protect the fish from burns.

In practice, automatic thermostats that have been in operation for more than a year do not always turn off. There is no consensus on the use of an aquarium automatic thermostat. Some hobbyists believe that at night the temperature of the water in the aquarium should drop, as in nature. Others are of the opinion that this is not at all necessary, since some fish live at the same temperature year-round for 20 years, and nothing bad is done to them.

Depending on what point of view a particular amateur adheres to, the question of whether he needs an automatic thermostat or not is decided.

The following brands of equipment for aquariums are known:

They produce immersion heaters, which have proven to be high-quality and reliable, designed for aquariums from 25 liters to 300 liters. They are also suitable for containers up to 1500 l.

Calculation of power depending on the volume and temperature of water

As already noted, the most important thing when choosing a heater is the power rating. It should have an indicator of 1 W per 1 liter, but in practice 0.7–0.8 W per 1 liter is used. It follows from this that before you buy a heater, you need to calculate its power. You can also adjust your own calculations using the parameters indicated on the device packaging.

Important! If you install a heater that is more powerful than necessary, it will continually turn on and off and thus will not last long.

The approximate volume-power correspondence is as follows:

• 25W - 10-25 l.
• 50W - 30-60 l.
• 75W - 60-80 l.
• 100W - 80-120 l.
• 150W - 120-170 l.
• 200W - 170-220 l.
• 250W - 220-280 l.
• 300W - 280-350 l.

This is a relatively rough estimate. It is imperative to take into account the difference between the desired temperature in the aquarium and the actual temperature in the room. It is important to remember that the heater must keep the temperature at a constant level.

Experienced aquarists place two heaters at half power at different ends of the aquarium, which ensures more uniform heating. From time to time, the water temperature is controlled manually; there is no need to recklessly trust the technology, it also sometimes fails.

Did you know? The aquarium, listed in the Guinness Book of Records, has a volume of 22.7 thousand cubic meters.

Breeding fish has its own subtleties. And the more their lover knows, the more luxurious his aquarium will be. I am happy myself and pleased to see the admiration on the faces of friends and acquaintances who came to visit.
