In-line Heater

Here is another post for my new 120 gal tank. There has not been water added yet... I still have a couple of things to complete before I do that. I just started the build of a rock background last night. I am hoping to have it complete by the weekend.

Back to the subject at hand. I decided that on this tank I want it to be really clean... no visible lines or hoses. I had several heaters laying around gathered up the parts and took a stab at it.

Here is my process:

Attach barb and adapter

Water tight cord grip to adapter. Basically a compression fitting.

Use PVC cement to glue slip connectors to clear PVC

I use threaded fittings where ever I can for maintenance purposes. Some may prefer slip.

Nice job! Appreciate the pictures to go along with it!

I got some of those cord grips and had thought about making an in-line heater like that but I ended up just using two Hydor 300 watt ETH that I already had and just did some custom plumbing. I had also bought and then returned the Lifegard Aquatics heater module. Wow that was a beast, could not fit it under the tank, its huge. I like the clear PVC that you did in the center also.

Awesome work! I never thought of trying to make a DIY inline heater before!

I'd rather buy a Hydor in-line heater.

Yes, Niice job! Especially with that clear PVC tubing!

Thanks everyone...

It was pretty simple once I got the cordgrips. I would have done the entire thing with clear pvc but it is so expensive. I got a crazy deal on the which i have. This cost me less than a hydor.

I am now trying to figure out how to get this tank drilled and other ways to hide cords.

You have water in it now?

No water yet... building a rock wall. Also trying to figure out how I will hide the pump and the cord for it. The next is trying to get this thing stocked. I am compiling my list of must haves.

No doubt that your heater is cheaper than a Hydor.
I think the cord grip that you used is designed to protect against external water splash, not sure if it can withstand internal water pressure. It may be OK but I don't know if it worth the risk.
Anyway, if you decide to use your DIY heater I hope and i wish that I'm wrong.

If the tank is acrylic, I believe you can use a Dremal tool to cut it (using the round open center bit instead of a solid drilling bit)

I am always trying to build stuff just to see if I can. Part of the fun for me is can I actually do it and make it work.

I spoke with Tap Plastics and they will do it for a buck per hole. Time to jack someone at the light for their truck.

PM sent, I'd call by my phone battery just died while I was talking to my daughter =(

There is some good info on MFK about building your own in line heater: [You must be registered and logged in to see this link.]

The part that is tricky to get a hold of is the cord grip. But you can request a free "Sample" from Heyco using this link: [You must be registered and logged in to see this link.]

See post#30 on the MFK link for part numbers.

I had requested a few samples but did not use them so if you are interested in trying this DIY project and need the part send me a PM, if your willing to pick them up from Tacoma.

That is the same cordgrip I am using. I have a few extras as well if someone wants one.
