一.What is an aquarium heater?
Aquarium heaters are the most commonly used aquarium supplies to heat the water in the aquarium, ensuring that the tank does not get too cold and that the temperature remains stable during the day.
二. What are the types of aquarium heaters?
By control method
The first generation of bimetal mechanical temperature control, the second generation of thermistor detection temperature control, the third generation of intelligent heater
The first-generation heaters directly use bimetallic sheets for mechanical temperature control, which is the most common. Simply put, a bimetallic sheet is placed inside the heater. A bimetallic sheet is a bimetallic sheet made of two different materials by a special process.
Combined together, when the temperature changes, the metal sheet will deform according to the temperature change due to the difference in expansion coefficient, using a bimetallic sheet to place a contact switch inside the heater. Automatic contact disconnection for temperature control, the disadvantage is that the temperature control is not accurate.
The inner bimetal of the thermostatic heater and its temperature control contacts are the control core of the heater. Low-quality bimetals are prone to fatigue during use, resulting in the inability of the bimetal to turn on or off the heating as the temperature changes. In addition, poor quality contact switches are also prone to fire and sticking, resulting in large temperature fluctuations. The advantage is that the price is relatively cheap.
There are three types of external contact materials: 304 stainless steel heater, glass tube heater and quartz heater. Later, another digital heater with controller was upgraded in the market. The same material is the above three. A digital display control box is added to make temperature control more convenient and safe.
The second generation thermistor detects the temperature type heater. After the signal is amplified, the on-off of the heater is controlled by a thyristor. We often call it an external temperature-controlled heater or a split temperature-controlled heater. how it works is
That is, the temperature control system controls the water temperature in the tank outside the tank through the thermistor probe, and heats it when the temperature control system is separated from the heating system. The advantage is faster heating and more accurate temperature control. The thermistor and heater can be placed in a
The distance is relatively long, which just overcomes the shortcomings of the bimetal temperature control of the heater. But other shortcomings are also apparent. First, the thermistor has an extra wire, which is more complicated to install. Secondly, if the thermistor accidentally leaves the water, it will continue to heat up, causing "boiled fish". tragedy. But now for this shortcoming, heating rods like Sensen and Chongxing have added thermistor alarm function for water separation and power failure. Many thermostats are controlled by liquid crystal display temperature.
The third-generation heater is an APP-controlled smart heater. For example, the heater of Jiyin can be controlled remotely through wifi through the mobile phone APP, and the temperature can be set within the safe range you want. is the latest heater technology. A set of systems that change an ecosystem from an unstable state to a stable state through the interaction of monitoring units, control units, and regulatory units. Compared with traditional heaters, traditional heating rods only have adjustment units, which cannot accurately identify the temperature and work mechanically. That's the difference in IQ.
Glass heater: generally adopts the anti-riot glass shell, which has the characteristics of low price and wide range of use, and can be used in various aquariums. The disadvantage is that it is easily broken. If used in a large aquarium, it must be equipped with a protective cover to avoid damage by the fish.
Stainless steel heater: generally adopts stainless steel shell, which has the advantages of sturdiness, durability and texture. But the disadvantage is that some corrosive environments, such as seawater tanks, cannot be used.
Quartz heater: Opal white quartz tube processed by special process, using resistance synthetic material, durable and corrosion-resistant, can be used in seawater tanks. But the disadvantage is that the price is relatively high.
Ceramic heater: PTC ceramic heater is a commonly used ceramic heater, which is composed of PTC ceramic heater and aluminum tube. It has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. There is also a MCH ceramic heater using alumina ceramics, which is a new type of efficient, environmentally friendly and energy-saving ceramic heater.
element with built-in heating wire. Compared with the PTC ceramic heating element, the MCH material is more environmentally friendly and saves 20~30% of electricity with the same heating effect. , and the service life is longer.
三. 16 aquarium heater for your choice
When choosing a heater, power matching must be considered. Generally speaking, high-pressure heaters should be used for large-volume aquariums. For larger aquariums, high-pressure heaters need to be used, which are placed on both ends of the aquarium, so that the heating is even and the effect is better.
四. Precautions when using aquarium heaters
1. Do not energize the heater in the air. Because it heats up very quickly in the air, it can burn out the heater at mild temperatures, or break glass or burn your hands. Even if the power is turned off, it cannot be taken out of the water immediately. At this time, the temperature is very high, and it is easy to burn the heater.
2. It is recommended to replace the bimetal heater after one to two years of use, because the internal bimetal heater is easy to fail after a long time of use, so as to avoid some unnecessary losses. The replaced heater is used as a backup and can also be used for heating when changing water.
3.Repairing the heater is not cost-effective. The relative price of ordinary bimetal heating rods is not very expensive, and the safety is not guaranteed after maintenance. Ordinary people do not have the ability to repair split heating rods. Hiring a professional to fix it can be as expensive as buying a new heater.
4. Be careful not to expose the heater when the water level is too low when changing the water
5.Observe the heater and thermometer frequently, do not rely on the indicator light of the heater, the water temperature shall prevail.
五. Experience using an aquarium heater
1. Aquarium heaters have a useful life, generally no more than two winters. Over time, the wires will age, the contacts will oxidize, and they may fail. Even imported aquarium heaters have a lifespan of 1-2 years according to the instructions. For safety, heaters and thermostats can be used in combination. There are many domestic thermostat brands, and the price is not high. Set the heater temperature to 2°C higher than the thermostat temperature, and double insurance can avoid the tragedy of burning fish soup.
2. I highly recommend that you keep your tank warm. Buying a few thick foam boards and sticking them to the back and sides of the tank to make a tight lid for the tank can greatly reduce energy loss. It only takes a little time and a little money, but it can save you a lot of electricity, why not do it? You know, every penny turned in is our own labor remuneration, why can't we live with our own wallet?
3. Heater placement: When raising large fish, the heater should be fixed, because some large fish can easily hit the tank wall and smash their tails. The heater should not be buried in the bottom sand, nor should it be in direct contact with the glass. There have been aquarists who broke the glass because the heater directly hit the glass
cause uneven heating of the glass. Placing the heater at an angle or flat will dissipate heat better, although it may not look as good. Because the heated water is rising, the temperature difference between the hot water generated at the lower part of the rod and the hot water generated at the upper part of the rod is relatively small, and the heat conduction will be slower, which undoubtedly reduces the
Heating efficiency, prolong heating time and waste energy. For clumsy fish like rainbows, it's a good idea to add a casing to the heater to prevent the fish from getting scalded. If there are two heaters in the cylinder, try to separate and heat evenly on both sides of the cylinder. The thermometer should be placed furthest away from the heater to ensure that the water temperature you get is not from hot water that has just been heated.
4.The red light of the bimetal heater does not mean that it is in good working condition, it is subject to the water temperature. Because if the resistance wire is broken and the water temperature drops, the bimetal will connect to the circuit, but it will not heat up, so the red light will stay on. Of course, sometimes when the temperature is reached and the metal piece does not break, it is also possible that the temperature continues to rise and a red light will appear.
