Types Of Aquarium Heaters

1. Submersible Heaters

A submersible aquarium heater is an aquatic heater that is placed inside the aquarium and heats water through immersion in it. It as a thermometer attached or separate to measure temperature of water. They are very popular among hobbyists, both beginner and advanced due to their ease of use and low risk of overheating the water.

2. Immersible Heaters

An immersible aquarium heater is a specialized device which is mounted in the aquarium but does not heat water. It transfers unused heat to water and make it more comfortable for fish to live in the environment. They are also called “passive” heater.

3. Inline Heaters

Inline aquarium heaters are a type of heater which is very convenient for fish keepers because they should be connected directly to the aquarium’s water supply line (pipe). They do not require any additional equipment and easily be inserted into the existing plumbing or can be attached to any new one. But because it is a heat exchanger, it will be necessary to install another heater in order to maintain the desired temperature. An inline aquarium heater is suited for large tanks which are more than 200 gallons (760 liters) and require additional heating all around the year, especially during colder seasons.

4. Substrate Heaters

A substrate heater warms the ground of the aquarium, which keeps cold water in the tank from cooling down. They are very efficient for tropical fish that like warmer environment and spend most of their time on the bottom of the tank. However, it is not recommended to use substrate heater for fresh-water marine fish because they prefer cooler environment and sometimes seek refuge near cooler areas in an aquarium.

5. Heating Elements

A heating element or heat cable is the simplest form of aquarium heater. It is a long coiled wire which can be mounted under the aquarium’s substrate to transfer heat to the ground and also maintain constant temperature in water. But it may not work properly in cases where there is high risk of external damage to the unit.

Buying The Best Aquarium Heaters: Factors To Consider

1. Size Matters

The size of an aquarium heater is measured in watts. The size of a tank can vary from as little as five gallons to several thousand gallons, all depending on the needs and preferences. A bigger tank would require a larger power capacity to heat water at a desirable temperature for the fish to thrive well inside it.

2. Type Of Heaters

There are many types of aquarium heaters available in the market. Each type has its own benefits and disadvantages that should be taken into consideration when deciding which one to buy for a specific tank.

3. Budget

The cost of an aquarium heater varies from as low as $10 up to several hundred dollars, depending on the kind and power capacity of the unit. Some depend on heat up time to determine their price, while others are priced according to the materials they are made with.

4. Easy To Maintain

Although aquarium heaters can be very reliable and cost-efficient in many ways, it is also important for fish keepers to see how easy it will be to maintain the unit in good condition.

For example, a heater that is too big for the tank will need constant monitoring to avoid overheating of water, he should replace it with small and more power efficient aquarium heater. Furthermore, some heaters tend to produce noise during operation which can be very disturbing when fish are sleeping at night or there are guests around during a day.

5. Automatic Or Manual Control?

Almost all aquarium heaters have two temperature settings which can be manipulated through manual and automatic control, depending on the user’s preference. Some fish keepers prefer having an easy way to adjust temperature while others like using slow heating process for their fish to adapt gradually with changing environment in the tank.

How To Install Aquarium Heater:

Aquarium heaters have to be placed inside the aquarium in order for them to work. If your tank is not equip with a heater, then you would need one that can be attached or put below the water line of the tank. This is where inline aquarium heaters come into play because they are specifically made to heat the water inside an aquarium.

Inline, or submersible, aquarium heaters are always placed under the water level of a tank and submerged in the tank’s water for them to function properly. They are also the simplest kind of heating equipment an aquarist can use because they require no additional setup before or after placement in a tank.

These heaters also come in different sizes, so if you have a smaller tank (up to 30-40 gallons) then you can always use the smallest ones, which should be enough for your aquarium. They are usually made of glass or plastic and the glass versions have a sealed plate on the bottom that prevents them from letting water into it. For safety purposes, you should always read the user manual before installing aquarium heaters.

Here are some instructions to better guide you in installing an inline heater:

Step 1 : Let’s say that you already have your preferred aquarium heater and now all you need is a hole in the water line of your tank. If not, then be sure to purchase a hole saw that will fit in the line and its surrounding area. This will allow you to easily cut out an opening for your new heater.

Step 2: Next, find the right size of piping (flexible tubing) that is long enough to go from one side of the tank to another without any problem. Follow this by making two cuts on each pipe for a total of four cuttings. Once you have the pipes ready, place it around the tank and then lower your heater into it while making sure that all of its wires are safe from getting pinched under the weight. Be careful not to doze off because if any part of your material gets trapped under your heater, it might get damaged.

Step 3: Once the heater is securely in place, run your wires using silicone tubing to hide them and make sure that they don’t come into contact with any metal part of your tank or anything else.

Step 4: Add some water inside each pipe and if it doesn’t reach the opening of your filter then you can use a water pump to make sure the heater is always submerged in the tank’s water.

When your inline aquarium heater has cooled or warmed as you have set it, then it will not turn off even if power supply is interrupted for as long as 24 hours. As such, you will need to wait for it to automatically go off before removing it from the tank’s water or disconnecting it entirely.
