What is a Pond Heater?
Pond heater, also known as de-icer, is a necessary device installed in a pond. It could be floating or submerged underwater. During the winter season, the build-up of ice is a primary concern of pond owners. Placing this device in your pond is an efficient solution to prevent even the build-up of gas within the pond.
How does a Pond Heater Work?
Some of you have probably thought that by using a pond heater, the water in the pond will completely become warm. However, it is not the case. The device only heats an area until a hole in the ice is created. And through that hole, harmful gases within the pond water could escape.
Most pond fish struggle every winter. The fish in the pond will be in danger if gases are trapped underwater because of the build-up of ice on the pond’s surface. You must keep the device on to maintain the hole.
Though not all pond owners need a pond heater, it’s a great help to those living in an area that experiences winter. You will need a power supply since this device operates using electricity.
If you want a floating de-icer, you only must place it on top of the ice and turn it on. And if you prefer the submersible type, place it at the bottom of the pond.

Why do You need Pond Heater?
Winter affects the survival of many pond fish. When the ice starts to form in the pond, filters won’t function properly. And when that happens, there will be less oxygen in the water that endangers your fish. The following are some of the reasons why you need a pond heater.
Fish Survival – Warm water would help the pond fish survive the cold winter. Although some fish can handle cold temperatures, you will still need a pond heater that could guarantee the survival of your fish.
Prevents Ice Formation – The use of pond heater prevents ice from forming in the pond’s surface. Although more oxygen is available in cold water, ice shouldn’t fill the surface of the pond. When the pond is clear from ice, the water can easily absorb oxygen.
Gas and Air Exchange – Though a pond heater can’t make the entire water pond warm, the water won’t freeze completely. It keeps a small area warm where the process of gas and air exchange takes place.
More Resistance for Fish – With pond heating, your fish will grow healthy. Pond fish won’t suffer from bacterial infections if their resistance is strong. You can help your fish get through the cold winter by installing a pond heater.
