dwalk Posted June 28, 2008 Report Share Posted June 28, 2008 I'm looking at getting a 5-6ft tank for my Cichlids. But I am worried about what it will cost to heat. Does anyone have info on this??. I have info in 3 ft 160L tank, but 5-6 ft would be 400 plus liters. Anyone in palmy/levin area willing to test this for me if I lend them my plug in meter?

Ira Posted June 28, 2008 Report Share Posted June 28, 2008 If you know how much for a 160, then do the math. It'll be roughly twice as much. Quote Link to comment Share on other sites More sharing options...
dwalk Posted June 28, 2008 Author Report Share Posted June 28, 2008 Someone told me that to heat twice the amount of water requires four times the energy (power) anyone out there know if this is true? Quote Link to comment Share on other sites More sharing options...

I have a four footer & a 150L tank & i think i noticed maybe $15 a month for them Quote Link to comment Share on other sites More sharing options...

No, it's not true. In fact, a larger amount of water will take proportionately less. More like the other way around, twice as much power to heat 4 times the water. As a tank gets larger(with the same proportions) , say double the dimensions, the surface area of the tank will go up 4X but the volume will increase by 8 times. It's the surface area that the heat is lost through, volume is pretty much irrelevant. Calculate the relative surface area of the two and you'll get approximately the relative cost for heating.

henward Posted June 29, 2008 Report Share Posted June 29, 2008 depends where the tank is if the place is warm, you will notice that heater wont be on much. the thing is - during summer, garages are usually hot. my heaters are hardly on n the summer.

When i light the fire it goes up to 30 without the heaters coming on. Quote Link to comment Share on other sites More sharing options...
