2017’s Best Aquarium Heater Reviews: Submersible With Thermostat
You may be wondering, do Bettas and other tropical species need a heater? Having a good heater is absolutely essential if you live in a cold place like Canada or Northern US. Neglecting to get a heater or getting a poor quality one can have fatal consequences, so we have some recommended products for sale down below to help you with your decision.
Why You Must Get a Fish Tank Heater
A lot of people neglect to account for the temperature changes that can occur in their fishtank. Just because the water starts out at the perfect temperature doesn’t mean that it will stay that way. When you buy a top rated fish tank an aquarium heater will act like insurance for your pet fish. In cold climates a change in temperature can be fatal for your pet so it’s important to maintain the temperature.
Another reason is that certain types of fish need to have the water temperature warmer than the room temperature. If the temperature isn’t correct for certain species then they can get stressed and their health can deteriorate or worse. These temperature changes can happen very fast which is a reason that large fish tanks are better than mini ones for newer aquarists, as it will give more time to fix any mistakes that may occur and save your fish. Check out our recommendations below and save your fish from temperature fluctuations.

Types of Aquarium Heaters
When it comes to buying a heater for a saltwater or freshwater tank there are a few different types to choose from like titanium or glass depending on where they will be used. Each has it’s own positives and negatives that we will go over below.
The submersible type is very efficient because it can be placed right in the water in any position that you want. You need to make sure though that you leave adequate space around it because your fish could become trapped between it and the gravel or the tank side. Also make sure that the heater never touches the gravel or the glass can crack because of the difference in heat conductivity.
This type which is commonly called a hanging heater is very common because it can be hung over the top edge of a tank and a glass tube that does the heating is put in the water. Another reason that it is such a popular choice for beginners and a staple in most aquarium kits is that it is very affordable.
In order to use this type of heater you must take precautions and secure it so that the glass sheath can’t be bumped into and broken. The consequences of the glass breaking can be fatal as it can start a fire or even electrocute your pet fish. Also this type is not to be used for marine or brackish aquariums because if salt gets into the tube then it will cause corrosion and short out the electricity.
You will need to make sure that your aquarium hood can accommodate this as well, although most will have a good sized opening for this.
Some filters actually come with their own built in heater which is very convenient. However, you’ll need to ensure that the filter keeps your water temperature correct.
Sometimes the heater is actually in the sump which makes it easy to maintain, although the sump requires a bit more space.
This heater is external and involves the filter or sump. It is good for bigger aquariums because it is inline between the sump or filter and the tank. The setup can be complicated at times but does stop the fish and the heater from touching which is crucial.
This type of heater is far more common in Europe than the US. The way it works is that the heating element is buried under the gravel and then the heat uses the warm gravel to heat the water. This type is recommended for planted tanks.
In conclusion buying an aquarium heater can be a must for some people. We hope that you were able to find one that fits your needs.
