TonyV Posted January 12, 2009 Share Posted January 12, 2009 I've been told by two different LFS on how to properly determine the wattage required when purchasing a new heater. One says to calculate the tank plus the sump while the other says just the tank. Which is correct? Current tank in process is an Oceanic Ultimate 58 reef ready with a 40 gallon sump. Heaters will be located in the sump for simplicity in the tank and I was going to go for the 2 heater setup in case one burns out. Link to comment
TheUnfocusedOne Posted January 12, 2009 Share Posted January 12, 2009 umm, tank plus sump i would stop going to the lfs saying just the tank, idiots what do the think the water in the sump doesnt effect the water in the tank? you will need to heat all 98 gallons of the system the duel heater is probably a good idea as it will also reduce stress on each individual heater just make sure ur checking them both on occassion Link to comment

I could be wrong though. I think the calculation is 3wpg... Link to comment
OB1 Posted January 12, 2009 Share Posted January 12, 2009 You have 98 gallons of water to heat. Calculate using total gallons. Another reason for two heaters. If one sticks on it won't overheat the system as fast. Link to comment
lakshwadeep Posted January 12, 2009 Share Posted January 12, 2009 I suggest only one heater. Two heaters is twice the chance of one getting stuck on. Link to comment
TonyV Posted January 12, 2009 Author Share Posted January 12, 2009 I figured I had to calculate the 98 gallons. It's always best to check with fellow reefers. Thanks. Link to comment
r20crazy Posted January 12, 2009 Share Posted January 12, 2009 another HUGE factor, is the ambient temp (aka room) vs. desired tank temp. let me find a chart............ edit: I cant find right now, to many beers. if someone else finds pls post up Link to comment
Phixion Posted January 12, 2009 Share Posted January 12, 2009 another HUGE factor, is the ambient temp (aka room) vs. desired tank temp. let me find a chart............ edit: I cant find right now, to many beers. if someone else finds pls post up Time for another guess game, Robert. Anywho, R20 is correct about ambient temp vs. desired tank temp. Ambient has a huge factor in what thype of heater or rather wattage of heater you may want to use. But you do want to guage this all by entire water volume to be heated which of course includes both the display AND sump. As for two heaters or one, each has I'd say equal pros and cons. It all comes down to personal preferance. But from what I see, if one heater sticks (using two heater method) I can't see how both sticking would be any worse than one single big wattage one sticking. Either scnerio will heat the water way beyond what's acceptable anyways. Only differance with one heater is that each part of the setup (display and sump) can be sectioned off from the other to prevent the entire system from over-heating if it's caught in time.
