Fluval E Advanced Electronic Heater, 300 W

I was having problems keeping my new tropical aquarium temperature stable, even though I was using the correct sized heater for my tank. So I did some research into my fluctuating heat problem. I found on the internet that my problem might be caused, by my house being too cold, due to me living in the countryside. It recommended that I used the next sized heater up from mine or to use 2 heaters to stabilize the temperature. Being that my heater I had was a 200 wat I decided to go for a 300 watt heater. My next problem was, which make to go for.. For this again I turned to the internet, on the reviews done on the different makes. I was guided towards the "Fluval E300" by being one of the top recommended by the review web sites. From there I went on the Amazon web site. I checked the customer reviews. They were very mixed, in their opinions. So I was unsure but noticed there was a couple of reviews that stated that if you followed what they had done, all was well & that would rectify those problems the other reviewers were having, while using this item. So it was at this point I ordered it, even though it was quite expensive compared to some others at Amazon. It arrived the next day via Amazon Prime Delivery. I eagerly unpacked it and swapped it over. I followed what some of the other reviewers had stated to do, just so I could get the best out of this heater. 1st; I placed it at a 45° angle in the aquarium, as per the other reviewers advice. 2nd; I made sure it had a good water flow over it 3rd; adjusted the temperature to what I required. Then left it alone to hopefully sort out my heating issues. The next day I went straight to the aquarium, to check the temperature of it, against my other thermostat placed on the opposite side of the aquarium to the heater, I was very skeptical at this point. Well low & behold it was within 0.4°c difference. Since having this "Fluval E300" heater I have checked the temperature on numerous occasions and the temperature hasn't changed, even during the night, when it is at it's lowest room temperature. I would definitely recommend these "Fluval E series" heaters but just be guided by the above advice and other helpful reviews please, and it will be a great product for you, just as it is for me 5++ highly recommended item time has moved on now and at least 6month & still the heater is perfect keeping good temperature

These may be more expensive then other aquarium heaters buy they are excelent. providing you give these heaters/thermostates a couple of hours to settle once you adjust the tempeture control they work perfect. hopefully these will last a number of years.

Of all the products i have bought on Amazon this has to be the most dissapointing! I have messed with this thing for a day now and after researching on forums and looking at reviews i can no longer risk using this. It is at least 2 degrees out and when the display is blue meaning the temp is too low to the one you have set, it doesn't even attempt to heat up. I got the 300 because it is rated for 350 ltr and my tank is 200 so it should easily heat that but it does nothing. I have moved it to an area of high flow across the sensor and that does nothing. The instructions state it should sit upright with the top sticking out the water (the min water mark on the surface of the water) but fluval technicians on forums are telling people to fully submerse them, put them at an angle, lay them horizontally, switching them on and off and toggle to the min and max setting before starting, all of which i have tried and it still does nothing. I have now got a standard heater that works perfect without any fuss just as this overpriced worthless load of junk should!!! There are plenty of good reviews for this product but there are too many bad ones and at the risk of the health of expensive corals and fish it is not worth it. If you send it back you will still have to go out and buy one to replace it so if it is faulty and you are sent a new one you will still be out of pocket. Not fit for purpose and completely useless!!!!!

I bought this Fluval E300 aquarium heater for my 4ft turtle tank. 6-years down the line & I'm still impressed. Came with a UK-plug. Mounted at 45° as suggested & made sure to always keep fully submerged. Never an issue with it. The built in housing makes it safe for my turtle to clamber over too & doesn’t need fully dismantling to clean like my previous guarded ones did. Excellent value & accurate enough 🙂

very nice heater which has an integrated guard to protect the fish and temperature display. when i first started using this i was also waiting for a replacement circulation pump to arrive and it was warning me of low flow (making the heater less effective) which disappeared as soon as I installed the pump. since then it has worked perfectly. however there is one disadvantage which I realised in the recent long spell of hot weather - I have to maintain a second liquid based thermometer because I want to turn this device off in summer - the ambient temperature is high enough to keep the water up over 25C so it seems a waste of electricity to keep it running just to monitor the temperature in the tank.

Purchased two of these years ago for a 500 litre tank. Buying new ones as they are very old now and I trust the brand but don't want to risk a power failure. Some people complain about it needing high flow, to be able to heat a 375 litre tank with 300 watts for example, DOES require good flow rate around the tank. Generally you want 1w per litre to be safe and keep a constant temp, more if your house is very cold. I find also if you have poor insulation on your house, or thin glass on our aquarium you will lose heat very quickly, this is why I run two 300w in my 500 litre, one as a backup set about 0.5c cooler than the other that kicks in if the other doesn't. I put one near my intake slightly at an angle and low to the bottom of the tank, the other goes on the other side of the tank underneath the spray bar, i positioned a small power head fan near the heater also to ensure my tank has good flow and good circulation meaning my heaters need to be on less. Also by having the two heaters either side it ensures a more even temperature in the tank. IN the 3+ years I have had these heaters they haven't failure, fried my fish. I also love the protective plastic around it, making sure any fish do not get stuck and burnt.

Really happy with how this was packaged! I've ordered a few heater from other retailers online and they always arrive shattered - happy to say that wasn't the case here! ✨ Despite some of the reviews - this heater did come with a UK plug! Would recommend this heater brand too! Thank you 🐢

Well I've now set up my tank put this heater in it and it's working fine upto now, at first I did not think it was working has it was on blue flashing I turned temperature up still nothing so I warmed the water up abit with another heater has I found out on yt it reads your tank temperature and if your homes cold it has a affect so I turned my heating up then at 4oclock in the morning it turned green to 28 degrees and its still green and I had to put it on a 45 degree angle they don't tell you that but instructions are to small to read but yt you find all you need to know it seems a good product box came wet and a bit bruised but it's OK I'm glad I brought it and would recommend too other ppl I also own the fx6 beast the fx6 is awesome

Bundan önce farklı bir marka kullanıyordum. Onda kalibrasyon gerekli olduğu için biraz uğraştırıcı oluyordu. Bu ısıtıcı tak, ayarla ve istediğin ısıya ulaş tercihiyle ön plana çıkıyor. Aynı zamanda çok dayanıklı görünüyor. Dijital ekranı ise onu rakiplerinden bir adım öne çıkarıyor.

Very well made thermostat. The outer protective casing is great to avoid fishes being scalded. Nice feature from Fluval. Setting the temp is also very easy with the toggle switch to increase/decrease temp value. The display is large enough for easy readout under water and is very clear. Would reccommend it to all. Been using it for just 2 weeks now. No issues as of yet, fingers crossed. Will update review if anything more to be reported for a long term review.

Fungerar perfekt. Skall klara 375 liter så jag köpte två till mitt 450 liters akvarium. Man kan ställa temperaturen med steg om 0.5 grader celcius. Är vattnet kallare än inställd temp lyser displayen blå, varmare är displayen röd. Håller vattnet inställd temperatur lyser displayen grönt och visar temperatur. Går blixtsnabbt att se status genom att enbart se färgen på displayen. Väldigt exakta med dubbla sensorer.
