I've done it

instead of heating up one location and circulating thru out, I figure it helps with heating up water faster and more uniformed. (having a temperature probe away from the heater helps it keeping in right rage as well.) and course having bigger heater is good too.
Can you tell me how this is not true?

And as original poster mentioned, didnt know it was issue with heat. ^^;
I never have heat problem after utilizing the external return pump and without chiller and fans. <

Having multiple heaters rather than one is a good idea, simply for redundancy's sake. But, that in no way saves energy. If you need 400w of heaters to heat your tank, it doesn't matter if it's a single heater or multiple heaters; 400w is 400w.

Since the water is circulating in your tank and at a rather rapid pace, spreading the heaters out has zero affect on how fast or evenly the water is being heated. The water temp will increase using the exact same power and take the same amount of time as if they were in a single space. Heat will transfer very quickly.

Thanks for clearing your statement. I figure that will be about right. I just figured it will be like a sound wave. you know. In my case I do have three remote tank all connected together (display, sump, refugium) So, I figure the heat will be transferred more evenly and faster.

Nope, but if the flow stops, you'll be glad you have a heater in each!

Yes, flow stops drastically on my 10 gallon refugium. I drilled two sump together. So the water don't flow in my refugium at same rate as is with rest of my system. :fish:

I have two that circulate air in and out of my canopy when my water temperature rises but I have yet to catch them on. I have a Reef Keeper Lite without the NET module so it's not easy to chart the temp or activity over time.
