Things to Consider Before Buying the Best Pond Heater
Choosing the best pond heater does not have to be a difficult proposition. You just need to pay attention to the most important features. This way, you will be able to buy a device that will best suit your application.
Here are the important things you need to consider:
Type of Pond Heater or Deicer
There are 3 main kinds of heaters that you can buy. They include: gas fired boilers, inline electric water heater, and pond heaters/deicers.
A gas fired boiler heats water within its system and then it circulates the water into a heat exchanger. The pond water is also pumped in to another chamber in the exchanger. Then the pond water absorbs the heat of the hot water from the adjacent chamber before being release into the pond.
For the inline electric heater, the pond water is propelled into the heating chamber of the heater. Then again the pond water comes into contact with a heating element. The water is heated before it is released into the pond.
Pond heaters or deicers are the most favorite because they are cheap and highly portable. There are two types of deicers: floating and submersible. A floating pond heater settles on the surface of the water. It maintains a sufficiently large hole for superior gas exchange.
The submersible version settles at the bottom of the water. It helps with gas exchange by keeping a specific area of the pond ice-free. A pond heater or deicer is the most popular choice among users, especially for those who own a small pond.
The Best Temperature for A Koi Pond
The optimal temperature a pond can operate on various considerably from one region to another. Most pond owners believe that fish require a favorable temperature for them to survive. But the temperature does not have to be extremely high.
In light of this, most pond owners would prefer a pond deicer that runs moderate thermostat wattage. A 300-watt thermostat can effectively keep a pond warm if it is submersible, and maintain a well-sized hole for gas exchange if it is floating.
Wattage and Thermostat
You must ensure that the type of pond heater you purchase is best suited for the size of the pool. Higher wattage heaters are more convenient for larger ponds. For instance, a zone of 3000 gallons would need a 1250 watt unit.
A smaller pond would need a pond heater in the range of 100 to 300 watts. Also, the best pond heater is one that is thermostatically controlled. Such a unit will turn on when the pond temperature drops towards zero degrees, and off when the pond temperature increases.
Size of The Pond
You need to buy a heater that suits the size of your pond. A smaller pond that accommodates only a few fish and plants will work best with a compact heater or deicer. However, you may need a sizeable heater, in case you are dealing with a larger pond.
Compact heaters or deicers come highly recommended because of the technology and features they come with. Most of them are engineered to run on their own with little or no intervention. They are also very affordable compared to the larger heaters.
Bigger heaters may be suitable for larger ponds. However, they are usually not technologically advanced when compared to the smaller models. You should be very careful when selecting the ideal size for your pond, because a larger heater may be a poor investment for a small pond.
Type of Fuel Used
Pond heaters run on different types of fuel, including: electricity, gas, and oil. You should choose a pond heater that runs on a fuel that fits your budget. Heaters that operate on gas and oil are usually expensive to manage.
In comparison, pond heaters that use electricity are inexpensive at first. Nonetheless, their maintenance budget may increase with time. However, the cost of maintaining heaters running on gas and oil may end being cost-effective with time.
