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?

If you know how much for a 160, then do the math. It'll be roughly twice as much.

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?

dont worry about power for a 5-6 foot tank. this aint marine. I have a four footer & a 150L tank & i think i noticed maybe $15 a month for them

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.

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.

this week when i have not loit the fire my tank has stayed at around 27.8 deg. When i light the fire it goes up to 30 without the heaters coming on.
