External Heaters - Anyone Got One ?

[Rooster]

I like the idea of moving the heater out of the tank (No, I dont want a sump ! LOL) so would like to hear from anyone using an external heater.... as far as I can see, theres only on manufacturer doing them, and it uses "a special ink" to make the heater ! doesnt sound reliable to me !

Also, there are modules available to fit a "normal" heater into, which sit outside the tank too... anyone used these ?


Thanks

My Hydor 300 is new, and it hasn't gotten cold enough here in SW OK for it to cycle on yet (the lighting and canister filters have enough residual heat to keep the tank happy).

I've got a splice kit ready to remove it from the outlet line just in case that heating ink (I still don't know what material it actually is) doesn't do the trick. Like you, I am a bit skeptical of its reliability, but the attraction of having the heater outisde and hidden versus inside and visible was too much to pass up.

Time will tell.

Anybody else got one that's had it working for a while to give us a good report?

v/r, N-A

i have a hydor 200 had it for a few weeks and cant fault it so far

I have two Hydor 300's set up in parallel on my 2026 Eheim external filter. Keep the temp stable to 0.2oC. Tanks only been running a 10 days at the mo. The only announce I have is hearing the thermostat click on and off. Bothered me a bit at the start as they are in my bedroom. No other connections were required as they fitted straight into my 16/22mm Eheim tubing. I have done a pick for you. (electrics like that any more before people starting moaning about how I'm going to die etc etc)

i am running 2 x 300w hydor exturnal on my tank and they have been working great for the last 10 months they heat up the tank much faster after a water change than other heaters

BUT i have heard that a lot of people have been having alot of problems with them lately and they just stop working for no reason one of my feinds has had one for 4 months and has had to exchange it 3 times the company he got it from has now told him that they will not be selling it anymore as so many have been retuned buy different people

they are a great idea lets just hope they sort out the problems they are having with them as i dont know if i would ever go back to having a heater inside the tank

MMMmmm, this is what I was afraid of ! Its is a great idea - dont understand why it hasnt been done before, they now use the same technolgy in their in-tank heaters, so maybe they need a while to perfect the thing !

I may go the DIY route then, and build a chamber for a "real" heater !

Several months ago, I replaced one of the two Ebo Jager 150W in my 55G with a Hydor 201 hanging behind it -
So far it has worked flawlessly -

I left the back up heater in the tank, just in case -
but as far as I know, it hasn't needed to come on yet -

I plan on giving the Hydor about a one year trial run,
then removing the in tank EJ 150W,
and adding another Hydor 201 in a bypass such as the 'Piper' has installed -

I have an Eheim ecco 2234 with a hydor 200 external heater, works great I've never seen the tank look so good. Plus I bought a spray bar for the inside of the tank so the cory's love it.

hydor's discontinuing it? It was such a great idea though!

i dont see how the way you have this set can work properly as how do you know that each heater is getting the same flow rate throught it

you will get the normall flow rate coming out of the filter but it could be going throw one much faster than the other cant se the point in it

i have 2 x 300w running on my tank but not like that i have one on each filter if your tank is big enought for 2 of the hearters then surly you must have 2 filters

It dont matter if one gets more flow than the other, just means one will turn on/off quicker. I got two incase one failed just as you would have two heaters in a tank. Temps are rock solid at -/+ 0.1 deg, so im happy with it. Got 600w of heating on 70gal, massive over kill but I dont really care.

You will if one goes faulty, and sticks on !

the end temp from the return pipe will always be the same which ever one of the heaters it goes through one will have more flow than the other so what if the one with all the flow stops working you will still be getting cold water as the water wont pump throught the one that is working how will the pump know which heater is working or now

you would be best of removing the loop effect and just running one after the other then the 2nd heater will kick in if the 1st one fails

There would be no point in having two if i put them inline to each other, as one would almost never be on. They both turn on and of almost simultaneously any way so must be working okay.
