An outdoor pond is every household’s dream. It provides excellent benefits to relax our minds.

Pond Heater

Commonly relates to de-ice, pond heater is a device usually installed in the pond to help your fish survive the winter season. It can heat the surface area within a specified amount of time, depending on the unit’s range and power. This is specifically ideal for those living in a colder climate.

No, it is not designed to keep away or melt all of the ice, though they will do so in a particular radius surrounding the device. What they do is keep your pond’s surface from completely freezing over throughout the winter period.

Don’t be confused with pond de-icers and heaters. They usually refer to a similar thing and are used interchangeably. Heater sometimes denotes to a much more costly, bigger units intended to heat the entire ponds, while de-icer is ideal for keeping a small area warm.

How Does it Work?

The device makes use of an inline electric heating unit, which produces heat to the entire pond. Hence, keeping your Koi or other fish completely safe and comfortable during icy months. It is important to follow the general rule of installing it. Otherwise, you can seek professional help. The heater should meet the minimum depth required, plus it must be placed at the pond’s deepest area.

Factors to Consider When Choosing the Best Pond Heater

Note that pond heaters are not cheap investments. So, make sure to consider these important factors before owning one to avoid costly mistakes.

Type

Submersible or floating? The former is a nice option as it is protected from various elements such as animals, wind, snow, etc., whereas the floating heater is ideal for a pond with a plastic liner. There are gas boilers and electric water heaters available too.

Pond Size

A single heater is more than enough for a small pond. But if it is bigger – wide and deep – then going for multiple units is recommended.

Durability

Of course, you want a long-term investment. So, look for a product that is built to last. Those made of solid stainless steel are gaining popularity due to their high impact resistance level.

Temperature & Wattage

The temperature varies from where you live. For instance, a small 100 or 200-watt pond heater is fine for a temperature that never gets at a lower place -10°C. Though if it plummet to -30°C, so look for 750-watt or 1500-watt device.

Thermostat

Modern pond heaters feature temperature control or thermostat so as not to injure the fish once it gets too hot as well as prevent gas buildup when it doesn’t get warm enough. This will add more cost, surely, but is worth the penny.

Energy Source

Numerous types of energy sources are used for powering up heaters – electricity, oil, and gas. Choose one which you think would simply complement well with your budget. Electricity could be a bit expensive. Gas and oil, on the other hand, are the ideal long-term cheap solution.

Maintenance

Especially if your schedule is so tight, you’ll want a pond heater that is easy to maintain to make your day less stressful.
