  • great heater for the price By boxxmann on 12/3/2014

    I purchased this heater to heat my reef tank because I recently switched from MH lights to Led lights and lost my heat source. I haven't has any issues with it, though, it is a bit long. I just put it in the front cornet of my 92 gallon corner tank directly beside the Hydor Koralia 1150 I also purchased, so the PH can move around the warm water in the tank. My thermometer is on the other side of the tank and is always reading 78, which is what the heater is set to. It is a very good heater and works well for my application.
  • Best Glass Heater Made By FirstContact on 11/10/2014

    This is the best glass heater manufactured. Period.
  • waste of time By peter on 11/8/2014

    Got one overheated, set to 65 hits 90 degrees. Second one has a 4degree drop from set point temp before heater works during the day time.. Yes it goes to 79.2 heater goes off, and the heater will only go on at 75.2 consistently. Thats a 4 degree or more swing in a warm 75 degree home. Total waste of my time. One bad thats part of life but 2 bad= total waste of time... Why bother with the calibration it doesnt work. Mine was off by 5 degrees can only adj for 2, wow thats fantastically usles(gimmick) just set it to the accurate thermometer no matter the dials readings. Then remember the temp differences. But its real hard to turn the temp control, like herculean.
  • Works great, very tall though By frost0fractal on 9/17/2014

    Be sure before ordering to check the dimensions, these are very tall heaters. The 200W model barely fit in the highest chamber of my 55 gallon sump. Otherwise they work great.
  • The best and most annoying, all in one heater By Daniel on 9/17/2014

    These heaters have very sturdy construction, great heating, large range, and easy calibration. The only problem is the temperature dial is extremely hard to change and the calibration out-of-the-box is wildly different from unit to unit. If you plan to crank it up to max and let your controller do the work, it's a sure-buy. If you plan to use the internal thermostat, you need to do some tinkering and would probably be better served by a different heater.
  • Best Heater EVER! By Powder Kat on 8/17/2014

    There is no better heater that EHEIM. Excellent construction (German) and keeps absolutely accurate temperature. Never had a temp swing. I've purchased every heater out there and none hold temp for more than 6 months. I use the old junk ones to heat my water for changes. I put the Eheim in the tank and never touch it. Keeps perfect temp.
  • Not the best option By Anna on 8/4/2014

    I bought 300W version of this heater and I can't understand why it is rated to heat up up to 250 gallons when it can't keep up with my 120 gallons tank. The temperature does not go above 75. I have to add more heaters to keep my temperature steady,
