Eheim Thermocontrol e200 Heater, Black, Wattage: 200W, Model Number: AEH3637090

Still going strong after one year. They're easy to adjust, are reasonably accurate (I use external thermometers instead of the built-in thermometer and temperature dial to identify the temperature the water is heated to). No issues with water getting into the heater, no broken heaters, and the cord is slightly longer than most. I use this brand heater with an ink bird monitor.

I like how simple it is to set the temp, it has a green light for on and water temp is good and red for heater on, it is accurate and way better than the eheim jagger tru temp heaters I would say awesome I highly recommend

Don’t buy Horrible customer support. Heating fogged up inside due to a leak. Emailed Eheim customer support 3 times to get it replaced. All I received back was a automated reply that a customer service representative would contact me Three months and that has never happened The Heater seems like a quality product Any brand can have a defect but if you don’t stand behind your warranty’s

The cord could be longer and should be. The temp sensor is accurate enough but I would advise investing in an Inkbirk or similar monitoring system, especially for any reef system. Suction cups are worthless, just buy an aftermarket magnetic holder. Always buy the largest unit you can to reduce duty cycle and heat transfer efficiency. The last Eheim unit I replaced lasted 3 years of regular use.

Eheim continues to set the standard for quality in aquarium accessories. I'm using this in a 75-gallon tank housing a yellow eared slider so durability is an issue because if you're a turt owner you know they absolutely love to tear s**t up. So far this heater is passing the full-on assault. Temp accuracy is off, hence I gave it 3 stars with a caveat, as this may only be incidental to this one unit. Generally, Eheim is rock solid on temps. If you need a bullet/turt-proof heater this is the one.

Like all aquarium heaters. You get good ones and bad. This one is replacing a 3 year old one that stopped working. So far so good. I do have it hooked to a inkbird. Will buy again

Solid heater!! It's built very well with heavy thick glass and a nice smooth dial for temp adjustment ..I have heater set at 79 and tank temp has been between 78.4 and 79.2. what you expect from ehiem.....

I have only eheim as I thought they had quality products. Was accurate when it worked. Have had failures within a year for 3 of this wattage, this one less than a month. Now that I’m looking, seeing water invasion on all 4 that I have of different wattages, 2 of which are quarantine and used only rarely and less than a year old. 3 year warranty-think again. Several emails, no response for a month old heater that died. No warranty based on this. Product is only as good as their customer service. Looking elsewhere for my heaters. Would rate zero if I could

These heaters are big, i originally ordered a 300watt model from a different seller, but when it arrived i found that it was actually too tall for my 240 litre Juwel tank, i had to return it for a refund and ordered this 200watt model instead, the heater arrived promptly and well packaged, I installed it in the tank a few days ago and it's working fine, the thermostat is easy to set with clear setting values (numbers) the temperature setting ring is quite firm to turn which is great as there's no chance of accidentally turning the ring and changing the temperature when doing tank maintenance, once set to the desired temperature the heater maintains this temperature without deviation, (set and forget).

Calidad alemana, muy preciso. Solo se debe colocar vertical, el fabricante es claro en este aspecto. No se necesita calibrar. Deben corregir esta publicación porque claramente dice que es de 150 watts y venden el de 200. El sku que ponen no es localizable para referencia.

Muy preciso y confiable, nada que ver con los modelos chinos

Well built, love the LED indicator. Heated up my 225l effortlessly

Fácil de instalar y la temperatura que se le pone es la que mantiene el acuario solo falta ver qué tan eficiente es en cuanto al consumo de energía
