[@lanyardloop]

As a retired electronics engineer, I can tell you the reason heaters fail is because they are designed wrong. With the correct design, the heater can last decades. It really wouldn't cost that much more to do it right. The current design hooks up the heating elements directly to the mains (Constant Voltage Source). They need to design it so the heating elements connect to a Constant Current Source. That way the heater can turn on and off thousands of times a day without the destructive current surges through the heating elements when it turns on. If the heater detects a low flow condition the electronics can throttle back the current to the heating elements. Another design flaw of most heaters is the electronics are in the same tube that the heating elements are, subjecting the electronics to high temperatures. High heat is the enemy of electronics. The designs that use a separate controller out side of the tank are much better.

[@nwcanuck5069]

Couldn't agree more and the heater manufacturers know this too. That's why they will never implement such a design because then they couldn't sell you another one when their flawed design fails. I'm not telling you anything you dont already know ;)

[@alis49281]

How long does a tmperature sensor last when seperated from teh heat source? I have one of the rare filters with a seperated system like you suggest, but the temperature sensor broke (physical force). I think it is a pt100 because these seem to be very common and I will replace it with such a sensor.

[@farmmouse3011]

I believe the titanium heaters are designed this way. The only problem I've had with them is the temp probes going bad. But at the same time I've had old glass heaters last over 15 years.

[@ericjbowman1708]

Way back in College I worked for an aquarium leasing/maintenance outfit. They always ran two heaters of different wattage. The lower-wattage heater did the bulk of the work. The higher-wattage heater was set a degree lower, so it only kicked on as supplement/backup. Tank being a degree under norm, indicated primary heater failure. Long-term strategy, but I worked on many 15-20yo aquariums with even glass catfish that old living in 'em, so I always run tandem heaters. If one should fail, Murphy's Law says it's gonna happen when I'm on vacation. Edit: I've never had a heater stick on since I was a kid with a cheapo Penn-Plax, lol.

[@ericjbowman1708]

14:45 Having worked at, and owned, aquarium leasing/maintenance businesses, the last thing we want is to charge a customer for *any* failed part. Different economics from an aquarium store entirely. When I liquidated, I kept my heaters, I have a bunch of green ebo's and those little brown ones I can't think of the brand, but never failed either. Pry 'em from my cold, dead fingers lol.

[@Raflm]

Damn, I tilted my heater right away and put it near my bubbles for flow. Thanks for the advice!!

[@stclairstclair]

Raflm, I put my filter intake tube near the heater to push the water around.

[@redarmysoja]

A warning to everyone who keep large fish concerning heaters. I had a 75 gallon tank with two Oscars, and as anyone who has kept Oscars know they can be rowdy fish. I went to feed them one day and noticed something shiny in the bottom of the tank. Reached in to take it out and it was the glass case from the heater. I immediately went to remove the remains of the heater from the tank, but it wasn't there. I found it lying behind the tank on the wooden tank stand, it had been there, still running, and had burnt the wood, I mean a serious deep charred spot. I'm just lucky my house didn't catch fire. So anyone with large fish capable of doing this beware, take precautions to avoid this happening. Myself, I quit using heaters altogether.

[@merfishsandwich691]

If you want to use a heater in this scenario you'd probably be better off to have your heater in a sump or somewhere outside of the aquarium.

[@redarmysoja]

@@merfishsandwich691 If you have that option, yes, but it's not always one people have.

[@drewh4911]

Nice job with the explanation here Cory. It would definitely be nice to have a heater with a heating curve, instead of a hard-set temperature to stick to.

[@neilscole]

"Retain as much heat as you can first" was the approach I've applied to my aquarium, which is currently in my basement. My basement is only semi-finished, so only semi-insulated. At least it's heated. So to keep as much heat as possible, the outside back and one end are covered with styrofoam sheets, and I usually have towels laying on top of my lid (which doubles to keep dust out). The heating I use is an under-gravel heating cable.

[@ItsJustMe0585]

My last heater JUST burned out... And you explained every thing I did wrong. Just fixed my mistakes. Thank you!! :)

[@TheRealDriftClan]

I've always put the heater right next to the output of my canister filter. Just makes sense to push the warmer water to the side that doesnt have a heater. Great information for people in the hobby struggling to manage proper water.

[@VetAquatics]

I'd love to see a heater developed by Aquatium Co-OP. The sponge filters you have are great, I'd imagine anything you guys produce would be cost effective and well made.

[@Korbert]

My personal experience is that once i started going with Eheim (Jäger) i haven't had a failed heater for over 10 years. They are all still going strong. Previously i had broken heaters every year.

[@TMAquatics]

Good discussion. I use heater controllers on all my tanks and set with a variance of +/- 2 degrees Fahrenheit. Less on/off cycles. Also use smaller than recommended heaters on most tanks and they heat just fine. 25w on 10 gal, 50 watt on 20 gal, etc. I’ve had 5 of the cobalt neo-therm heaters and all but one has failed.

[@AquariumCoop]

For some further info for us, what was the purchase date on those cobalt neo therms?

[@TMAquatics]

Aquarium Co-Op Cory, I purchased two when they first came out (2014?). They both failed and were replaced by Cobalt in 2016 or 2017 before the warranty expired. I had also purchased an additional Neo-therm. The new heater and the two replacements were acquired after Cobalt “fixed” the issue which caused early production heaters to explode/crack. Only have one still working. Most of them failed by sticking “On”. Only one had a cracked housing.

[@medallo143]

What about 5 gallon tanks? It's hard to find good quality heater for less than 25 watts.

[@callaway86]

They can easily make a better heater, seriously it's 2021, they have electric cars that go 600 miles. It's all about cheap Chinese manufacturing and forced obsolescence.

Thank you for this video. I bought the new Sera heater and it's by far better than everything I've used in over 20 years.

And the weather is quite fluctuating here in Portugal during the winter. Thank you!

Be careful if the manufacturer Does not warranty the heater that long, your looking at a fire hazard, hazard to your tank, fluctuations in temperature can harm fish sensitive to temperature change. Please for the sake of the hobbie, your life, the life of your fish. Get a new heater!!!!!! Immediately. Test your tank water with more than one thermometer. Check digital against glass thermometer. Always have a way to verify your numbers. Also Never assume a heater is good, always have. A back up waiting to throw in the tank. Check to see if you are having fluctuations In temp with that old heater your using, if you care about your fish, that are living breathing ANIMALS, stop treating them like there a Peasant, they are as important as our cats or dogs.

[@catfishcave379]

You’ve been reading my rants! (Maybe) I love these “how to properly use your equipment” videos. I always put my heaters (which are E. Jager) either next to the filter intake or output, horizontal and below water change level. And set them to winter water temps for the fishes natural habitat. (Shrimp don’t need a heater for ex) Ha ha ha... I use a lot of 50w & 75w heaters in the house and don’t go to 100w except for the garage tanks with bigger tanks (unheated garage). I also add rigid insulation to the back of my tanks.

[@AquariumCoop]

When i experimented with insulating tanks, I find it didn't help as much as I would have liked. A glass top did help a lot though. Eliminating super cold air near the tanks helps as well.

thermostats are rubbish for heat control, either full on or fully off, this puts strain on everything else but its the cheapest solution for the manufacturer, a PID controller like used in incubaters is far more accurate and coupled to an ssr relay no moving parts, its whats in your cruise control in your car, imagin trying to hold 50 in your car using only full throttle or no throttle, almos imposible. thats just what a thermostat does.

[@nancyware7282]

Hey! Something I was actually doing right all these years! I keep my house cooler due to health issues, so my tropical tanks have always had heaters. I place them so they are either under the water return of the filter, or there is an air stone/bar under them, figuring that would help circulate the warmed water better than just sticking the heater in the corner 'out of the way'. Once the fully submersible heaters came in, I was mounting them horizontally on the center back of the tank, and again running air directly beneath them. Maybe why view only had one heater not last longer than five years (and that because it got dropped on the floor). Not trying to blow my own horn here; it's just nice to find out I was doing it right. Thanks, Cory!

The height is the same. I am looking at getting the Eheim Adjustable Calibratable with overheating auto shut-off for both tanks. Being a newbie, I unknowingly bought the pre-set heaters for my Betta Starter Kit Tank and for the Quarantine Tanks (1 10G & 1 5G... because it made sense at the time. Now, I know better. They over heat up as high as 82°F... not good for some plants... so I since learned. Great job in explaining how heaters work and why they should be placed diagonally.

Use an external/separate thermostat to regulate the temperature and set the internal thermostat a couple of degrees higher, then you have a failsafe if it should get stuck and you won't boil your fish. I make mine myself and have WiFi access and monitoring on them, not that hard to do if you got some knowledge in electronics.

[@Bogrin]

I have to say as someone just entering the hobby these videos have been invaluable!

[@djknauss1]

it would be interesting to know the day/night temp fluctuations where the fish are found locally. It would probably differ between fish found in large lakes vs streams/rivers. I don't think multiple cycles of heating and cooling during the day is the answer, but being able to set a day and night target temperature to get one nice temperature ramp up during the day and cool down during the night should be the goal. This would probably only be feasible using a heater attached to a variable wattage controller. Assuming proper heater use (located in higher flow area, placed at 45 deg, etc), the large number of variables (tank size, ambient temperature, target temperatures, etc) would necessitate developing a complex heating algorithm or ultimately an AI algorithm to control temperature to achieve previous stated goal. In other words, ultimately a computer controlled device. As far as safety is concerned, on any tank with livestock i wouldn't risk using a heater without a thermostat. Additionally, if I had a really rare/endangered/extinct in the wild species, I would probably go to the extreme of DIY'ing a heat exchanger system that would physically isolate the heated water from the tank water, to prevent heater ruptures from possibly contaminating the tank and killing livestock. Interesting topic. Fluke makes temperature data loggers that would allow accurate data gathering. That would be my first step.

In my 125 I use 2 x 150 watt heaters instead of a 300 watt. If either one fails (in the on position) it's not enough to cook the fish. If one fails (in the off) there is enough heat from the second heater to keep them alive until I replace it. Costs a bit more but with a tank full of expensive fish, worth the investment.

@@SuperRoverboy not that often but since I've about 70ish tanks in my shop I handle alot of heaters and accidents happen 😁 I mostly use and sell aqua nova heaters since their selling price is pretty much what a jäger heater costs to stock..

Thank you so much my heater wasn't working for 2 days as soon I looked at your video and turned them correct it was working straight away thanks 👍

[@KittyKatForeverAndEv]

what type of heater have you got??? Heaters are expensive going through them is a pain

[@puirYorick]

Cory, if you keep speaking *truth* like this, they're gonna get you one day, buddy. Keep fighting the good fight.

[@AquariumCoop]

Well, we do fight against that currently with companies. I believe this education benefits the companies even. Long term, customers having success far outweighs more heater sales this year in terms of profits for a company over the next 20 years. The problem is who is looking at the profits at the end of the quarter? That is who is making the decisions for these companies.

[@puirYorick]

@@AquariumCoop I couldn't agree more, sir. The issue of putting Quarterlies ahead of a firm's long-term prosperity did eventually kill one company I once worked for. As soon as it went public, the accountants managed us into the ground with zero comprehension of what we were doing or why we existed at all. One of the big reasons I continue to listen to your videos is for your attitude towards a healthy business prosperity model. A private entrepreneur with the attitude like yourself is the best model for good capitalism. Best Wishes!

Great info and advice! I use a heater from the Polish company Aquael, platinum heater 50W. I looked on YT and on the internet how to properly set it in an aquarium. In the end I decided to add it at an angle. Watching this video I'm even more happy to done so...and also for my filter, that is close by, to provide flow to the heater. The heater has an electronic measuring system to show the actual temperature, but just to be sure I always have my regular thermometer in the aquarium. When I do my water changes I'm always careful to first unplug it and let it cool for 15-20 min and then start to lower the water. I use it since August 2019 and so far so good. But I'm always surprised to see my fish eating food from it...like it's not that hot.

[@AquaSplendor]

On another hand, their reason why heater need to be precise, when you have a saltwater tank you don't want a lot of deviation.

[@AquariumCoop]

While this is true, most saltwater hobbyists have problems with too much heat. This is why external water pumps exist, methods on how to make a screen mesh top etc. I still believe it to be the same core problem just from the other side instead of being too cold, it's too hot and heat management is the key.

[@jackjill521]

Excellent video!!!! We've been running our tanks with heaters as you have described for over 4 years now. All has been going great for us. Trying to educate fish keepers is tough!!! LOL!!!!

Couldn't not could

[@erint5373]

This is so insightful, and great for us newbies. My follow up question is in regards to general running costs of pumps, heaters, coolers etc. Here in the UK bills have gone up by nearly 400%this year, so I just want to gauge that I can afford the running costs longer term. Most UK houses dont have aircon, so I believe the heater at a minimum would be required. But want to do right by the fish, at a cost effective price.any suggestions?

[@perseverates]

Same.

[@Axqu7227]

Validation! I have never felt so validated as a hobbyist. The reason my no-name garbage brand heaters have kept going for a decade and my buddies' expensive ones keep failing is because I always put my heaters right under the filter's outflow. My reasoning was aesthetic, to make them both easier to hide, but I'm so glad I was accidentally doing it right all along!! Both because of the heat coming off the filter making it easier on the heater, and because it's in the highest-flow part of my tank. Now I keep my aquarium room at about 75 and only run 1 heater (for a frog that needs about 80) and I can tell you that if most of your livestock need similar temps, heating the whole entire room is really the way to go.

[@donttalktome4696]

I put the flat aqueon one directly into a hang on back filter. Works great

[@R-Dan]

So far this winter in eastern Ontario Canada I've had no heater in my tank. Just heat the room and the Temperature has been fine. Fish are still active and healthy

[@nortonfamily0514]

I've been considering a temperature controller to help with this. Any recommendations on one? I've never seen one in a local store. Anyone tried to recommended one on Amazon?
