Larger Heater for Open Top Tank?


I'm in the process of slowly setting up my 112G tank which will have a clear netting top. I'll be using Eheim heaters and based on their recommendations I should be aiming for 250W. This seems to agree with online heater calculators, however, these calculators assume there is a glass top on the tank (at least all the ones I've found). Obviously with an open top tank there will be more evaporation which means there will be more heat loss. But I'm not sure how much more.

Looking for input and suggestions, especially if anyone ever went from a covered tank to an open top tank (did you have to buy a larger heater).

Thanks,
Harry

I think it depends on what you put in the tank. If it can deal with cooler temps. you should be OK. The tank will run cooler in winter for sure and that will largely be determined by the room's ambient temperature. You could run 2 150W's to be on the safe side, especially if you keep the room cool in winter as most do.

I'd probably aim for a 300W heater. You can always turn a bigger heater down if it gets too hot; but sometimes a heater just doenst have quite enough "oomph" when you're working it near capacity. I would suggest that with or without a closed lid.

And that is the right answer.
