Winter. Even the most foolhardy of us know that it’s time to hibernate. For some of us, that means sub-zero temperatures. For others, relentless winds and snow drifts the size of sand dunes. And for some of the lucky few that means a blessed few weeks of weather hovering near or around the 32-degree mark.
No one likes shoveling snow. Or slipping on patches of ice. But imagine living underneath those conditions for months on end? That’s what your outdoor fish or amphibians have to put up with every single day during winter. And to make matters worse, once the water temperature falls so do their body temperatures.
More importantly, the algae and vegetation they feed on die during the winter, resulting in an accumulation of frozen gases which can harm and even kill outdoor fish. But there is a solution.
Pond heaters and de-icers are becoming increasingly more popular among owners of koi and other outdoor fish ponds these days. At one time prohibitively expensive, their prices have dropped dramatically over the past few years. But does affordability also ensure reliability?
We’ll take a look at some of the more popular brands of pond heaters currently available, as well as provide a useful guide to keep in mind when purchasing one.

Pond Heater Buying Guide – How to find the best pond heater for your needs.
Despite the fact that the term “pond heater” and “de-icer” are virtually interchangeable, there’s a significant amount of difference in models to take into consideration before your purchase.
While most manufacturers offer models that are floating, there are some that are still entirely submersible. More common is a floating/submersible hybrid. What are the differences?
Floating models stay on top of ice and water; which means no inherent danger to plastic ponds or PVC liners. On the other hand, submersible units are protected from dangerous elements such as wind or heavy snowfall which cannot only rob a de-icer of heat but can destroy it.
Ensuring that the wattage unit is suitable for your pond is critical. Higher-wattage units are more suitable for bigger ponds but may overheat smaller ones, while low-wattage units may work perfectly on small ponds but prove insufficient for larger ones.
Wattage units and size vary from climate zone, however. For handy reference, you can find a quick guide here: http://khmfg.com/pdf/chart_pond.png
Pond heaters can run on either electricity, gas, and oil. Ultimately this is contingent on your budget. Gas and oil are costly; and while electric may seem affordable at first, frequent usage and maintenance may increase over time.
There’s no denying that a fish pond is one of the most natural and perfect ways to beautify your property. And we wouldn’t be surprised if you spent a drastic amount of money stocking it. Doesn’t it make sense to spend a fraction of the cost to keep it alive?
