Interpet Nano Stat Fixed Temperature Aquarium Fish Tank Heater, 25 W, for Aquariums up to 25 Litres (5.4 Gal)

Fantastic. Used for 3 different tanks - up to 20L. Heated perfectly. Have found that since upgrading to a 40L tank the temperature has dropped a little - from 25 to 22 degrees. Still ideal for my tropical fish but may consider buying a more powerful heater and using this one for the smaller tanks. Easy to use, suction cups are super strong !

This product has work perfect for the first 6months and recently it not working, had to get a new heater.

Heater works well heating my 26 litre tank, but heats up over the 25 degrees the heater is preset, I've taken a couple of readings & both are 27 degrees upwards, time will tell if it will affect any fish I put in the tank as it was a starter tank for my son

Nice and little, neat and tidy, great product of you ask me,, might buy another to put the other end as my tank is a little larger by 2-3ltr , but as it's self thermostated it won't boil the fish, which seems to be a main concern, so for me just setting up again with a little tank , it's a win win and a thumbs up from me

If you read the small print in the instructions they say that the ambient room temperature needs to be greater than 20 degrees! So if your room temperature doesn’t remain at 20 degrees or more then this heater is useless! This is a temperature booster, it raises the temperature of the water 5 or 6 degrees above ambient temperature….

As many reviewers say it goes up to 28° instead 25°. Shame.Besides this letdown, the heater is nice and small and fits nano aquariums very well.The problem is, I wanted 25° Celsius and I can't return it now that I used it.

Needed a mini heater for a nano tank for my Betta. Works great very small form factor but a reassured by the brand as I didn't want to risk it. So far so good

I was a bit concerned after reading some of the reviews about the heater boiling the fish so I erred on the side of caution and bought the smaller heater. I have a 3 gallon tank for a very old small tropical fish when winding down my big tank. By rights I should have bought the 25w heater as the cut off for the 10w is 2.5 gallons. It took hours to heat up the tank and it was a gradual process. I have a stick on glass temp gauge which showed me the heat got to 24 and stopped. It’s been like that for 4 days now and is pretty constant so the fish is now in its new home. The water isn’t going to reach 25 but that’s fine. All in all I’m happy with the product.

Gute Heizung für ein sehr kleines Aquarium

The heater should keep the temperature at 25 degrees but it heated my tank to 27-28 degrees.

Je l’ai commandé pour un Betta sauf que c’est une prise anglaise alors j’ai dû commandé un adaptateur de prise anglaise vers prise française pour pouvoir l’utiliser… des frais en plus… je ne peux pas juger de sa performance pour l’instant vu que j’attend de recevoir l’adaptateur, merci pour mon Betta qui en attendant patiente dans une eau à 20 degrés !!

Mann sollte in der Beschreibung darauf hinweisen das am Heizstab kein EU Stecker verbaut ist.
