How to Choose a De-Icer for Your Pond or Stock Tank

barnIt’s that time of year again. Short days, long nights, freezing temperatures, wind chills, snow…winter is fast approaching. And even though temps are still above average in many parts of the country, it won’t be long before winter has its icy grip on most of the nation. Which means now is the time to start thinking about how you’ll keep your stock tanks and ponds ice-free when the temps plummet. When it comes to buying de-icers, you have a lot of options out there between different wattages and types of de-icers, like sinking, floating or ones that fit in your tank’s drain plug. To make your choice easier, we’ve come up with a few things to look for when purchasing a de-icer. First, let’s talk wattage. The wattage is the measure of electrical flow to the unit. When it comes to a de-icer, the higher the wattage in the de-icer, the more efficient the unit will be at heating the water. The higher the wattage, the faster it will heat your water, and the less overall energy it will use to do so.
Tank Size Less than 70 gallons 70-100 gallons 100-300 gallons
Recommended Wattage 500 watts 1,000 watts 1,500 watts
When you’re looking to buy your de-icer, follow the guideline below for the amount of wattage your specific tank will need. icer-1 icer-2 Your next option to consider when purchasing a de-icer will be choosing the right style. You’ll see choices for de-icers that sink to the bottom of your tank, models that sit in your drain plug, or models that float. Below is a chart rating each style when it comes to efficiency, animal safety, which ones are best for plastic tanks or best for Rubbermaid tanks.
Purpose Floating Sinking (and Drain Plug models)
Efficiency Best Average
Animal Safety Average Good
Best for Plastic Tanks Average Good
Best for Rubbermaid Tanks Average Good
It’s also a good idea to look for a de-icer that is thermostatically controlled, meaning it only operates when it needs to. These de-icers are more energy-efficient since they have a thermostat inside that senses when the water temperature dips below freezing and powers the unit on until the water temperature reaches a set point above freezing. It’s important to note that these de-icers won’t heat the water and make it feel warm; their only purpose is to keep it from freezing over. Next, take a look at the cords. Are they protected in any way? Look for cords with anti-rub or anti-chew protection. Anti-rub cords generally feature a tough plastic jacket over the cord to protect it from rubbing and fraying over time. Anti-chew cords are wrapped in metal wire to discourage chewing from livestock. And whether you buy a sinking de-icer or a floating de-icer, adding a guard is always a good idea for an added measure of safety for your livestock. This cold season, keep your tanks and ponds ice-free with a little help from a de-icer! Pond Deicer more info:
