What To Search In Your Best 100 Watt Aquarium Heater

If you’re looking for a fish tank heater, our list of the best might be able to help. Whether it’s your first time or just want some tips before getting started with one-time use – here are some features that should factor into what kind of water circulator system would work well in your aquarium.

Safety And Security

Safety Is The First Priority

In my opinion, the best aquarium heaters have a very high degree of safety and trustworthy safety features. 

Some tank owners are willing to take that risk with an inexpensive system that works most times but not all – I’m not one of those people!

That’s just how I roll. No compromises on the security and wellness of aquatic life for any factor!

The price difference between an average heater and a high-quality one isn’t THAT significant, apparently – so you can buy whichever is cheaper!

But a safety feature that should be on every aquarium heater you buy is the ability to automatically turn off if water gets too hot or low. Any device without this will not do, as it could potentially lead your fish to harm!

Nowadays, it’s easy to find a heater with all the features that you need. However, you’ll additionally desire an indicator light so that your water stays at just the right temperature and also has another LED or LCD display for ease in monitoring these settings on any given day!

Wattage With Tank Size

100 watt for 20 gallons

A wattage of an aquarium heater tells you the quantity of power output it has. Basically, this is how well your fish tank can be heated up with just one unit! Be careful not to buy an inefficient product for yourself and ensure that it won’t damage any other devices in your home. 

You don’t want to get a unit that’s too strong or weak for your fish tank – the ideal wattage range is 3-5 watts per gallon.

That means a 100-watt heater would be sufficient in heating a 20 to 30-gallon fish tank.

Temperature Control

You hardly ever see aquarium heaters on the market nowadays without the option to adjust the temperature. However, most models allow you to set the temperature. 

It’s vital to realize how crucial adjustable settings are for tank owners who want different types of aquatic life to thrive in certain water conditions!

A fish tank is only as good of a home for your favorite aquatic friends if its temperature level is ideal. A lack in this department will cause just about any aquatic life form to struggle and die, so keeping it at perfect levels where you’re happy with the way things are going has excellent benefits!

Price

It’s important to frame pricing expectations when it comes to the best 100-watt aquarium heater. As you probably guessed from my mini-rant before, I am never a fan of going with the cheapest option if it means sacrificing safety or well-being for life in your tank.

This is why I am so happy with my list of Best 100 Watt Aquarium Heater. We all know the pain of not finding that perfect heater for our needs. But with this list, you can find what works best without breaking either your wallet or your heart!

Possible Problems With Aquarium Heaters & Solutions

Yet if you buy the best 100-watt aquarium heater, there is always a possibility that electrical equipment like this may fail. There are several reasons for their failure, and when in doubt, it’s important to check whether your fish feels comfortable or not! The possible points where an aquarium heater could go wrong include:

  • Heater explosion
  • Cracks on heating elements
  • Heater meltdown
  • Failure of built-in thermostat
  • Loss of heater’s internal thermometers 
  • Reduced control accuracy
  • Changed saved settings after a power outage

You can increase the lifespan of your heater by using two smaller heaters instead of one large model. So instead of buying one heaver-duty 100-watt heater for your tank – buy two smaller 50 ones because those seem like better investments, in my opinion (I’m not rich, so please take what little knowledge I can give).

Another good option is that you can buy a separate temperature controller instead of buying two smaller heaters. This will be independent of the main aquarium heater and provide more precise control over how hot it gets in your tank, making sure nothing becomes too warm or cold on its own accord!

Types Of Fishtank Heaters

Submersible: Submersible heating systems continue to be submerged in the water and are typically shutter-proof and shock-resistant. They last longer, are more excellent in top quality, and a bit of bit expensive also.

Hang-on-back or immersible: Immersible heaters are placed on top of the fish tank like a HOB filter. They likewise remain partly submersed but aren’t totally waterproof like completely submersible heaters.

Inline heater: Inline heaters are external heating units created to use inline with a canister filter outlet. Water needs to pass through the heating element to get heated up.

Heating cable: The heating cable is the most basic kind of heating system. You have to position the coil beneath the substrate. However, these heaters are appropriate only for freshwater fish tanks.
