saltwaterfishman February 28, 2014 Share February 28, 2014 I was wondering, what do public aquariums use to heat their tanks? Large heaters or something else? Link to comment Share on other sites More sharing options...
zygote2k February 28, 2014 Share February 28, 2014 I know from experience that large commercial systems use a variety of heaters like any of the following: 1) Heat Pump 2) Hayward Pool and Spa flowthrough heaters up to 11k 3) Drop in Titanium heaters in various sizes and wattages up to 5k 5) Gas fired heaters Link to comment Share on other sites More sharing options...
davelin315 February 28, 2014 Share February 28, 2014 In addition to what Rob said, we also use a lot of regular old heaters, just not on the big systems for obvious reasons as well as inline heaters made by... drawing a blank here... Link to comment Share on other sites More sharing options...
OUsnakebyte February 28, 2014 Share February 28, 2014 I've never run a system with a heat exchanger, so I can't speak for those. For my systems that need a heater, I favor the titamium heaters with controllers from Aquatic Ecosystems: http://www.aquaticeco.com/subcategories/5329/IHC-Submersible-Titanium-Heaters I use the ones that draw a hefty amperage - 12-18 amps. So, be careful of overloading your circuits. I also have a couple that run on 230v, so that will help too. Stainless steel will eventually not be stainless in saltwater...

mling February 28, 2014 Share February 28, 2014 ....... Stainless steel will eventually not be stainless in saltwater... ................... You hit the question that has always been at the back of my mind ! I always use titanium heaters after breaking too many glass ones due to carelessness. How do you know when you have to replace a titanium heater ? Link to comment Share on other sites More sharing options...
OUsnakebyte February 28, 2014 Share February 28, 2014 I've only ever replaced a titanium heater when the cord has frayed and worn out - not b/c of the titanium heating element... Cheers Mike Link to comment Share on other sites More sharing options...
