Already Frozen Ponds

  • If the ice on your pond is more than 2 inches thick, drill a hole with an ice auger and place the Thermo-Pond over the hole. Do not chop through the ice in smaller ponds as the shock waves can damage or kill your fish.
  • If the ice is only 1 or 2 inches thick, place the Thermo-Pond on the ice and it will melt its way through the ice.
  • Try to position your Thermo-Pond within arm’s reach of shore to avoid walking on thin ice.
  • Snow and ice should be removed from the top of your Thermo-Pond.
  • Always keep safety as your number one priority. Never walk on thin ice.
  • Please consult your pond professional on tips for overwintering fish.

    Super product for the price!

    By Fish on Feb 23, 2021

    Did a great job! Went through the snow episode and kept a clear circle of water open which I think contributed to our fish making it through the severe weather. When the snow and ice melted our little fish was gathered around it obviously could feel some of the heat from the heater! I’m enclosing a picture.

    Works pretty well

    By Wellcrap on Jan 10, 2021

    I have a 4500 gal pond with koi as old as 37 years (yes, really that old) and I use 3 of these at different areas in the pond. They work well and are cheap to operate. In SUPER cold and wind, you sometimes have to pour a bucket of hot water in the hole to get it unfroze, but that isn't an everyday occurrence. They will last you about 3 seasons, so cost effective as well when you figure in the electric savings. I've tried them all in 40 years, and this became my choice for my finned kids about 10 years ago. Won't use anything else now.

    Winter pond

    By Daver on Feb 21, 2021

    Excellent heater for fish to winter over. Brought one of these from a pond place about 10 years ago, broke a hole in it with a snow shovel, needed to replace it.

    wonderful product

    By BESS on Jan 7, 2020

    I have used many different pond heaters and this one has been the best so far. This type of heater is not designed to heat the entire pond. What it does is keep an area of the ice open so the gasses can exchange allowing the water for the fish to release build-up. I have had to replace this heater a couple of times, each time it has last about 3 seasons. For the price and quality, it is worth it. It uses minimal electricity and does the job.

    Only good if you want to go ice fishing.

    By Ducks on Nov 20, 2019

    I purchased this in hopes of keeping an area in my pond from freezing. From what I read in the details before I purchased, that is exactly what it should have done. The only spot that is left unfrozen is inside the hole. It does no good for my ducks.
