Can I run only one heater?

[PirateLove]

Hi RC. I have been using two heaters, one 100-150w and a 50w but I want to get rid of extra cords in my sump. Will running one heater be too hard on it, with it turning off and on/running nonstop? Also can I run a 200w?
Thanks!

One of the main reasons for using 2 heaters is if one fails the remaining heater can help keep some temperature in the water, or if one sticks on its usually not enough to heat the water too much (although a controller is a good idea for a stick-on failure). 2 heater are generally more efficient at heating the water too, less load per heater (unless they are undersized)

It is possible to run a single heater however.

Ive always run one heater, I have a 300w Ehiem Jager on my 75 gallon, does a fine job.

What he said. Depends on your risk tolerance.

Two cords doesn't bother me as bad as losing all my livestock

I use two or three heaters in all my tanks, for the reason stated above, when they go bad they usually stick in the on position which can quickly cook a tank killing all your livestock. Using two heaters at half the needed wattage will give you some time to spot the problem before your tank fries. Even with a controller I use two heaters.

A single heater is fine if it's a premium one. Just check the tanks temp daily. The notion of two using less electricity is incorrect. These heaters simply click on at full power and off when the desired temp is reached. There is no lower draw by being split over two or more heaters.

I disagree. All heaters fail, and usually in the on position. But if you can live with the consequences . . .
