Comments: When I first opened the box the quality of the heater was apparent. It was well packed ready to go. The temperature settings were easily read and the heater was easily installed in the tank secured by the twu suction cups. I have not had to do anything with the heater since installation which says alot about the product qquality. I would definately recommend this heater to my friends

Comments: This is perhaps 6 or 7th Eheim Heater I have used. Needed higher wattage than ones I have so the purchase. It generally tends to be bit more pricey, but very reliable and good product. Tried others but did not work as well.

Comments: Heater is solid.. I can see some people being confused about calibration.. i see lots of threads on it.. i knock a star for the instructions not telling the consumer how to revert back to factory setting calibration... i had to email them for how to set to factory settings. once calibrated, this thing is running great.. no complaints. From Ehiem: To reset the heater to factory setting, ensure that the red arrow is pointing at 79 Degrees and the back red pin is aligned with both the power cord and the blue/white pin. they sent pix as well.. cannot link here.

Comments: These are good heaters in general. I use one size up from the recommended. ie. for a 90g tank I would use the 250w instead of the 200w. *Thermostat works well, usually within +/- 1deg. *I replace these heaters after two years of service - that is when I typically see issues with the thermostats. I knocked .5 stars off because I have had issues with longevity, however; I don't mind spending ~$35.00 every few years.

Good overall heater

Reviewers Rating Great


Posted: 3/29/2015 from BOULDER CREEK, CA UNITED STATE
4.0 5
Experience Level: Intermediate


Comments: It's a decent heater and the thermal protection is a plus. The thermostat is not particularly precise. I put two of these in my q tank. One is turned down all the way to 75 F but it keeps turning on when the temp is still 79 F. The other heater is set at 77 and it rarely come on. It's probably best to have an aquacontroller run this thing. Another minor complaint is the rubber suction cups. Is it really that expensive to equip it with a magnetic holder?
