A pond heater is a type of heater that you use to keep your fish pond warm in the winter, or
during cool spring or fall periods.
One thing that a lot of people do not realize is that it is not necessarily the cold that can
kill fish, but the fact that gases can get trapped underneath the ice once the surface freezes completely.
These gases need to be released, much like humans need fresh air so that the
area they are in can be rid of carbon monoxide and carbon dioxide.
If these gases are not expelled, they can hurt the fish and the rest of the nutrients in the
A fish heater will keep the ice from forming over the water in many instances, and will also
help to keep the water at a more suitable temperature for life.
A lot of these heaters simply float in the water and are electric powered.
If you own a fish pond, then you should
definitely look for a pond heater or pond de-icer that is powered at least up to 100 watts. This will generally
keep a pond that is up to 1000 gallons from freezing over completely. Of course, a bigger pond will need a bigger
pond heater, but this is a good starting point to go from; also consider the possibilities of a solar heater.
You should also make sure that the pond heater in question does not damage the liner in your
pond. You might also try to get a pond heater that is energy efficient, as opposed to one that is going to cost you
a ton of money in the long run.
