Factors to Consider when Choosing the Best aquarium heater

There are several factors to take into account when selecting an aquatic heater. We have listed below a few of them, go through each and keep these in-mind while selecting the aquatic heater for your aquarium.

  • CostDon’t just buy any heater by paying a high price. It might not be the one suitable for your aquarium. First and foremost fix a budget. Then you need to do some research, know your options and familiarize with the product you intend to purchase. The product should offer the maximum service for the price you are spending.
  • Easy maintenance – Buy a heater that is easy to maintain on your own. An aquarium needs to be maintained properly and this means cleaning is required at regular intervals. So go for a heater that is easy to clean.
  • Safety measures while buying heater also keep in mind the safety of your aquatic lives. There should be no risk of electrocution, the heater should keep the water temperature stable and there should not be any fluctuations, which can be deadly to fishes.
  • Features Go for heaters that come with some additional features like a thermometer to show the exact temperature it is at, automatic cutoff system if there is any fluctuation of temperature and availability of covering to prevent the fishes from getting in touch with the heater.
  • Size of the heater This is an important factor to keep in mind while buying a heater. The size of the heater should be accurate for the size of your tank, how much water it need to heat up, what is the room temperature? These three points should be kept in-mind while deciding the size of the heater. The heater should supply enough power to heat up the water in the entire tank and keep it at a stable temperature.
  • Placement of heater – This is another factor to be taken into consideration, the position of the heater in the aquarium. The heater should be placed in an optimum place so that it can provide the function intended and also do not cause harm to the aquatic lives. Heaters depending on the type can be placed vertical or horizontal, inside the tank or in the filter, near the inflow. Choose a perfect position depending on the type of the heater.

Types of Aquarium heaters 

There are different type of heaters available in the market. Some of them are

Immersible Heaters / hanging heaters

Immersible heater

These are apt for those whose are on a tight budget. They are cheap and offer the service it is intended for. They heat up the water by direct contact, the heating pad with its outer covering will be hanging inside tank water (usually at the back of the tank) and the heat control system would be above the aquarium. They can easily break as in most case the outer covering is made of glass. This can also pose a threat to the fishes, if there is glass breakage electrocution is a possibility. There are heaters with titanium outer covering by they tend to be on the costlier side.

Submersible heaters

Submersible heater

Unlike immersible heaters they are fully submerged inside the tank. These can be placed anywhere in the tank, the best effect is obtained if they are placed horizontally or vertically. Most of the submersible heaters are provided with suction cups so that they can be positioned in the glass tanks properly. These are also cheap compared to the other types and bit pricey than immersible. They are more reliable than immersible heaters.

Substrate heaters

Substrate heater

These as the name suggest are placed under the substrate (material used at the tank bottom for example gravel or sand) in the aquarium. They are not commonly used. They contain coil of wires placed in the bottom of the tank under the gravel, when switched on the wire heats up and radiate the heat to gravel which in turn transmit it to the water thus heating up the water evenly throughout the tank. When the water is heated up they automatically switch off. The only and greatest downside to this heater is that in case of maintenance or any issues the whole tank has to be torn down to provide a fix.

In – sump heater

In sump heater

These are placed inside the sump and not in the fish tank. So the fishes does not come into contact with the heater, which makes them safer than in-tank heaters. There is no fear of fish being electrocuted or breakage. They are easy to maintain also as they can be removed and fixed without causing any damage to the fish tank.

In- filter heaters

In-Filter Heater

As the name implies the heaters are placed inside the filters and water gets heated as it passes through the filter. These heaters are more appealing as they are not placed in the tank and are hidden away in the filter. They are also apt for heating up large tanks of water. Only downside is that if there is any issue the whole filter need to be taken out.

In- line heaters

In-line Heater

These are placed between the sump and the tank. They are external heaters as it is not placed in the tank. The water enters the heater through a pipe, where it gets heated. After heating the water is flown back out to the tank. These are also good for large aquariums but are also expensive.

So while opting to buy a heater for your aquarium, go through the factors mentioned above, fix your budget and then go for the heater best suited to your aquarium.
