Water Garden & Features Q & A
Q: Do I really need a pond deicer? It costs a small fortune to run it. Are there any other options? – Mary in Indiana
A: You’re right! Some pond deicers do cost a lot of money to run – but there is an alternative. Unless you’re lucky enough to live in a climate that doesn’t freeze, your going to need some type of device to keep a hole open in the pond during winter months. When a pond develops a layer of ice, a deicer is used to melt a small hole in the ice allowing toxic gases to escape and oxygen to enter the pond. For years, this has been accomplished by just using a deicer.
Unfortunately, the deicer can also melt a hole in your wallet. Pond heaters use anywhere from 100 watts (for ponds up to 600 gallons) to 1,500 watts (for ponds up to1,000 gallons) of electricity. When you consider utilities charge from 8 to 15 cents per kilowatt hour (1,000 watts of electricity used in one hour) depending on the location, the price of running a deicer can cost more then $75 per month!
The good news is that an aeration system can also keep a hole in the ice – and do so for a lot less money. For instance, Water Garden Aeration Kits use a high-efficiency air compressor that operates with as little 12 watts (that’s 88–99% electricity savings!) of electricity to push air to the diffuser. The action created by the air causes the ice to weaken, eventually creating a hole. This aerator also helps to add oxygen and circulate the water below the surface.
To install an aeration kit in your decorative pond, place the compressor near your power source. Make sure the compressor is covered – a faux rock cover is perfect for this application. Attach one end of airline tubing to the compressor and the other end to the diffuser. Place the diffuser away from the deepest point of your pond and no more than 4 feet below the surface. Plug it in and you’re ready for the cold weather!
Another benefit to an aeration system is that they can be used all year long. Aeration works great in the summer, providing oxygen for your fish and keeping your pond free of muck and debris.
If you already have a pond deicer and plan to run it this winter, save money with the ThermoCube – it can cut your electrical cost in half!
