How To Heat Your Fish Pond Using A Tankless Water Heater

In cold climates typical of lots of the USA, Canada and Northern Europe tankless pond water heaters are used extensively. In top koi ponds the water heaters are in fact highly sophisticated automatically controlled gas fired tankless water heaters in many cases. For smaller ponds and larger fish tanks immersion or tank water heating is used

Koi Pond Tankless (Gas Fired normally) Water Heaters

This type of tankless water heater is not just to prevent the water from freezing it is meant to maintain a water temperature by continuous heating of around 15 degrees C or 55 to 60 degrees F. At these temperatures koi continue to feed well and thereby continue to put on weight and body condition under the heated water conditions.

When considering tankless gas or electric water heaters design and installation is critically important and expert help should be sought. Materials of construction for the tankless water heater should ideally be stainless steel.

For smaller ponds or koi holding tanks a submersible (immersion type) heater that lies on the bottom of the pond can be adequate. The heater is normally protected in such a way that it does not touch the bottom of the pond or the sides of the tank or pond wall. While plugged in this electrical tankless water heater must always be submerged and the controller must be protected from the elements.

As a rule of thumb (although it depends upon many conditions) you can assume a kiloWatt (1,000 watts) is enough electric power to heat about 250 US gallons by 10 degrees F ( about 8 degrees for Imperial gallons) and maintain your tank or pond at that temperature

Make sure any tank or immersion type heater is electrically protected .
