HiTauing Aquarium Heizung, 50W/100W/300W/500W Tauchheizung für Aquarien mit Übertemperaturschutz und automatischer Abschaltung beim Verlassen des Wassers für Salz- und Süßwasser

I currently use seven of these heaters in various freshwater aquariums (three 50W, two 200W, and two 500W models).Performance & Reliability: While I've only had them for a few months, they've been consistently reliable and accurate in temperature regulation.In one of my tanks, I have two of these heaters, each on a separate external temperature controller (heater set at 80°F with secondary thermostat at 74°F), creating excellent redundancy. This arrangement provides complete fault tolerance - the tank would only overheat if both the heater and its corresponding thermostat failed simultaneously, and would only drop to room temperature if both heating systems failed together. Despite being power-cycled multiple times daily through this setup, the heaters maintain their setpoints and continue to function flawlessly.Design Improvements vs. standard heaters:These should theoretically outlast traditional heaters for two reasons:-They use thermocouples instead of bimetallic strip thermostats, which are less prone to wear-The control logic is located outside the water in a pod on the cord, reducing water exposure to electronicsInstallation Consideration: The only potential issue is that the heater is permanently attached to the temperature controller. This means the thinnest part of the assembly is actually the heater itself. For tanks requiring the power cord to pass through a small opening (like my euro-braced tank which does not use a conventional lid), you'll need an opening large enough for the entire heater assembly to pass through.Additional Features: They include an extra suction cup, which is a thoughtful touch.**General Aquarium Advice:** For any aquarium setup, I strongly recommend using two smaller heaters rather than one large one. This provides limited fault tolerance without introducing the complexity of my external thermostat setup. If a heater sticks on, being lower-wattage, it will take longer to overheat the tank, and if a heater sticks off the other will still provide some heat. I wouldn't trust any brand of heater without at least this level of redundancy.Bottom Line: Highly recommended based on my experience so far. These heaters deliver on the essentials with some smart design improvements over traditional models.

Bin sehr zufrieden!!!Die Heizung erfüllt seinen Zweck,habe subtropische Seerosen die die kalten Nächte nicht mögen .Die Temperatur ist jetzt konstant,ist auch einfach einzustellen, hätte mir nur gewünscht das das kleine Papierchen,was sich Gebrauchsanweisung schimpft,auf deutsch gewesen wäre.Ich kann es weiter empfehlen.

I've had this for a month and it works great. It maintains a better temperature than the fluval brand that I used before. It has a built-in temperature display that is very accurate. The temperature is very consistent. I do have a back-up thermometer, and it also verifies the consistent temperature with no fluctuation. I trust I will know if it quits working because of the display. The fluval had a red light that was on even though it had burnt out and I did not know it had quit working. My tank is 5 gallons with one beta. It is bigger than my last heater but doesn't show on the black backside of my tank.

I have tried so many heaters over the years, and this by far the best, and relatively well priced to.Instructions are ludicrously simple, even my 7 year old could figure it out (if you need to switch between Celsius and Fahrenheit, simply hold the button - as it even says in description).I only have a small 45l tank, but this has kept the temperature regular since I purchased.As the instructions state, do not leave this switched on when you remove from tank to clean, this is a really silly thing to do. Simply unplug, clean your tank, change your water etc, reintroduce to tank, and when full again, turn it back on, not difficult.NB: when unplugged, the heater does revert back to factory settings, so you will need to press the button a handful of times to get it back to your setting.The only time this could present a problem is if you're a regular holidaymaker and there's a power cut, as it will reset to factory setting. However, I personally check my temperature on the big digital display daily, and it takes literally a second, so for day to day use, this would never present a problem.All in all, for £20, it's great 👍🏻
