Before recent times, Koi ponds were only heated by professionals.
Heating a Koi pond coasted so much money that only those people who lived in warmer areas kept this fish.
Because of decrease in cost of heating, it has motivated a number of people living in colder regions to have their own pond where they can keep their Koi fish.
If you are not living in a hot climate, it is suggested that you consider heating the Koi pond.
Absence of ice will not solve your purpose. You will at least need to maintain a temperature between 54-57F.
This will reduce dangerous fluctuations in temperature and allow your Koi to feed all year long.
These imported fishes can be protected by use of a heater.
You’ve made the investment, why not protect it.
Basically there are two ways to heat a Koi pond.
The best and most simple way of heating Koi pond is by installing an inline electric water heater.
Gravity-fed system inlet is the best area where you can fit an inline electric water heater.
About 1000 gallons can be heated by using a water heater with a power of one kilo watts.
Ambient temperature of water is an important factor that affects the performance of water heater.
Water heaters and a pond deicer that have more power than what is needed are always a better choice.
A heat exchanger system is another effective option.
Because of a cheap operating expense, it is preferred even when it has a high buying and installation costs.
The heat exchanger is basically a radiator that pond water is pumped through to warm.
The water in the radiator is heated by a small boiler that is fired by natural gas, electricity or oil.
Do remember to cover the Koi pond during winter months, even if you do not heat it.The covering of Koi pond should let some air pass.
The best covers have zipped openings to allow gases that build up to escape and to allow access to the fish if needed.
