Pond heaters or pond de-icers are a necessary pond accessory for all Koi or other fish keepers as it is important that the pond water is kept at a stable temperature to ensure a healthy environment for fish during the cold winter months.
Pond water heaters usually come as a submersible pond heater or as a floating pond deicer. Submersible heaters lie on the bottom of the pond and must be completely submerged when in use. They heat a larger area than a floating pond deicer would. are the lower cost option and the easiest to install.
Fish can usually survive in a garden pond during the winter months provided the water is deep enough. If you have a shallow pond you should use either a pond heater or a pond de-icer. If you notice bubbles forming under an iced over pond, it could be methane gas, which is toxic to fish if it is not allowed to escape. If your garden pond does ice over and you don’t have a pond heater or pond de-icer, an alternative method is to place a pot of hot water on the ice surface until it melts through, allowing the methane to escape.
A floating pond deicer floats on the surface of a pond and works by melting a hole in the pond ice cover. This allows gases to escape during the freezing winter months. Pond de-icers contain automatic thermo-regulators that turn on whenever the water temperature drops below 40-degrees Fahrenheit. Pond de-icers are the lower cost option of preventing a garden pond icing over and are the easiest to install.
To determine the size of pond heater you need, consider that it takes approximately 1000 watts to heat 250 gallons of water to 10-degrees Fahrenheit. You will need to make your own calculations based on the size of your garden pond.
