I have an Ebo Jager 100 watts 120 volts heater and a Penn Plex 200 watts 110 volts heater. Which uses more electricity when the light comes on? Do you look at the volts or the watts in determining how much electricity it uses. I know Ebo Jager can heat a tank a lot better than a regular heater.
 
doesnt the amount of water you heat determine the ttl amount of electricity you use to set it at a certain temp?

the heaters are essentially really really really inefficient light bulbs, turning all that electricity into heat instead of light

so how to ebo jagers work better? o.o
 
My LFS has always said that Ebo's
"run hot" and can be used to heat larger tanks than normal. and given their new 300w size is rated for up to 265g I believe they think this too. I believe it is because of the way that heat is distributed to the water more efficiently.

you will notice that Ebo's are much longer than other heaters of the same wattage.

this is to provide more surface area for more efficient heat exchange.

on the back of the new 300w size that they have, it explains more.
 
watts measure the amount of energy used in a time period
volts x amps = watts

Where else can the heat go, except into the water?
 
if you have a 100w heater in a tank too big for it, it will likely end up using more power in the long run do to always trying to play catch up.
The 200 will use more in smaller amounts of a tank the same size vs the 100.
also 110 and 120 is the same when it comes to voltage ratings. most outlets range from 110 to 125 but usually are around 119.

Yes it does. But like 12volt said, the 200w will draw more power when operating, however it shouldn't run as long as a 100w.

110-120v are interchangable. If you connect a volt meter to your wall outlet it might read 112v or 120v or 118v, etc. We have some electricians on the board that could probably give a better esplaination.

I was thinking because it is an Ebo Jager 100 watt heater, they can do a better job in heating a tank.
