Pond Heater – Winter Protection For Your Pond

A pond heater is used to ensure that fish and plant life remain healthy even during the winter months. A pond heater can be used to de-ice the pond, or to heat the pond all year around. If you only want to remove the winter ice, then you need a de-icer rather than a pond heater.

If you plan to keep your koi fish in the pond all year round, and you live in a cold climate, then you’ll need a pond heater. It’s best to aim for a temperature of around 40 degrees Fahrenheit for your pond. This will keep your Koi happy and help deter bacteria from growing.

There are 2 types of pond heaters:

1)    Submerged Pond Heater
2)    Floating Pond Heater

In addition to this you’ll need to choose whether you want your pond heater to run on electricity, gas or oil. You might also want to consider a solar pond heater. They don’t require wiring, are easy to set up, and are very energy efficient.

A submerged pond heater sits below the surface of the pond. It will heat a larger area than the floating pond heater. A submerged heater will also use more energy than a floating heater.

A floating pond heater sits on top of the ice of the pond. It works by melting a hole in the ice and allowing the pond gases to escape. It is more energy efficient than a submerged pond heater.

No matter what pond heater you choose, you should seriously consider a backup heating source. There is nothing worse than hitting winter only to find that your pond heater isn’t working.

Even if you don’t have a backup heating source, you should still consider other winter safety measures. It’s best to change the pond water. Koi fish need to have their diets altered in winter. You can get a mesh pond cover to protect the pond from debris. Also make sure you remove your pond pump when you install the heater. Pond heaters and pond pumps don’t mix!

If you use a pond heater and continue to monitor your pond temperature throughout winter, your koi fish and plant life will thrive into summer.
