Note on the Importance of Properly Sized and Functioning Aquarium Heaters: A very important aspect to choosing the correctly sized and powered aquarium heater for your system is called Temperature Ambiance. Essentially, technical talk for - consider the environment and temperature conditions where you live...
- Some live in climates that are quite warm all year round, so they may not require the recommended heater size for their system as described in the guideline above, and can be safe to go with a slightly lower wattage than the guideline above as to not overshoot on heat generated. These hobbyists may want to pick up an Aquarium Chiller as well to ensure that their tank can be cooled if needed.
- Others live in climates that remain quite cold year round, so they may consider choosing a heater that is slightly above the recommended heater size guideline for their system as described above, so they can have a bit of extra juice when winter rolls around.
- Others live in climates that are warm half of the year, and cool the other half, in which case we'd advise getting two or more heaters for their system that evenly split the difference between the recommended heater size guideline for their system, and set one to turn on at the lowest temp they'd like their aquarium to be kept, and the others 2° cooler than that (Ex: Heater 1 = 78°, Heater 2 = 76°). That way, full wattage is only being used when needed, and the system temperature remains flexible.
This is also important to consider for the immediate environment of the tank. Do we usually keep our home, office, or room that our aquarium is in warmer or cooler? We can follow the same guidelines above to help determine what's best for temperature control of the tank's immediate environment.
Heaters are one of, if not the most common reasons for failed aquariums, because of either failing on (heating up the aquarium and cooking the tank), or failing off (not turning on and freezing out the tank). We make sure to only list the most reliable heaters that have been tested over many years in many different systems and environments all over the globe. However, as with any electronic aquarium equipment, there's always a chance of failure, which in the case of heaters is catastrophic.
For this reason, we strongly advise to fully replace your tank's heater system every 12 months. This will ensure that the delicate instruments that cause the heater to function properly are always fresh and in peak operating condition when in the aquarium, to minimize risk of failure and maintain a successful aquarium life support system. It's been our experience that the few extra bucks saved by holding off on a heater replacement for a few more months are far outweighed by the financial and emotional damage from a cooked or frozen out tank.
We also highly recommend that whenever an aquarium heater is purchased, it should be partnered with an Aquarium Heater Controller, which regulates the heater's function while also acting as a fail-safe if the heater fails on or off. Absolutely invaluable, and for the price, a very wise investment in the longevity and overall success of our system.
The final option to full-proof an aquarium heat control system is an Aquarium Thermometer. Some heaters come with a temperature indicator included, but to be honest, most of these are quite cheaply made and are not reliable in terms of accuracy or longevity. To bulletproof your setup, invest in a quality Aquarium Thermometer to act as a standalone visual indication of the precise temperature of your water.
Some choose to invest in multiple heaters to partially fix this issue, but at the end of the day, we've found Annual Replacement Heater Purchases, Aquarium Heater Controller Fail-Safes, and Aquarium Thermometers to be more effective and full-proof. However, multiple heater investments are especially effective at higher tank sizes (anything 150 gallons or above).
Heaters are a very important and often overlooked topic in the aquarium industry. If you're still unsure of what exact heater size and wattage will be best for your system or what equipment is needed to full-proof your system, visit the "Questions" tab so we can advise on what heater will create the most successful aquarium for your individual situation.
Here is an Instructional Manual for the Eheim Jager TruTemp Heaters. Keep in mind that these heaters are distributed globally, so thus manual is multilingual. We've trimmed the document to only include English Instructions on pages 4-6.
