5.0 out of 5 stars Best heaters out there.
These Eheim heaters are built tough and built to last too! I get 5 years service plus out of mine. I won't own any other brand, and neither should you.
5.0 out of 5 stars Big heater, but works great... A quality heater
When it comes to aquarium heaters, this is one of 2 brands I trust. This one, made in Germany and the other made in Italy. I have never had Jajer heater let me done. My only issue is that they are physically bigger than other heaters. They are built to last and they do.
4.0 out of 5 stars Works well but it’s very long
Keeps good heat but it’s very long so it has to be angled in my 21 inch tall tank.
5.0 out of 5 stars Strong and long, lol.
Working great to heat my 150 gallon at 81 degrees. I have this in a high-flow area of my sump (bottom left in the picture), and it works great. It’s a little hard to get in and out, because of the length (this thing really is long!), but it’s working great. Feels sturdy, buts its glass, so obviously be careful with it. I will probably buy another one for redundancy, but one is working fine so far. I have it plugged into an inkbird controller, and I have every confidence that this heater will work for quite some time to come.
5.0 out of 5 stars Easy to setup
It does a good job, works great, EZ setup.
5.0 out of 5 stars Great brand
Have used this brand for years - highly recommend
5.0 out of 5 stars This heater is reliable.
You get what you pay for. This heater may cost a little more, but it's never fried my fish or let them freeze. Well worth the money. I've learned not to buy any other brand.
5.0 out of 5 stars Great aquarium heater
This is the one heater I can count on
Quality heater
I ordered the 250 watt as a backup for my 180 gal (always have a second heater in my tanks). I received the 300watt for some reason but I’m not complaining, luckily the tank was tall enough.
Muy robusto y de calidad
De los mejores del mercado sin duda, son costosos pero justifican su precio.
