How it Works


  1. Turn off the pool pump.
  2. Screw the Device into the pool inlet. A
  3. Attach a garden hose to the outlet at the top of the Device. b
  4. Lay the hose in a sunny area.
  5. Place the discharge end of the hose over the pool. C
  6. Turn on the pool pump.
  7. Adjust the cap on the face of the Device towards a closed position to force water into the garden hose. You may need to aggressively close the cap to fill the garden hose. D
  8. Once water is flowing from the opposite end of the hose, adjust the flow to approximately a ½-inch diameter or smaller stream. Remember: The longer the water is in the hose, the warmer the water will be when it exits.

C. Place the discharge end of the hose over the pool

Helpful Hints

  • To increase the temperature of water entering the pool, use the longest hose that your space allows.
  • To reduce heating time, adjust the water flow to maximize the size of the stream at the time of day when the temperature is the hottest.
  • Works best in conjunction with a solar cover.


  • Always make sure the discharge end of the hose is located securely over the pool.
  • To avoid damage or injury, remove the Device when the pool is in use.
  • The Beluga device is NOT designed to pump water to high elevations such as roofs of houses. Using the device in this manner will damage the unit and may damage your pump. Please do not use the device to lift water more than 5' from the pool inlet.
  • The Beluga NOT recommended for filtration system with a pump that is less than 1 horsepower.
  • To prevent damage consult your pump manual before installing the Beluga device. 


How much hose do you need?

The amount of hose you use is entirely up to you. Fifty feet is sufficient in most cases. Keep in mind that the longer the water is in the hose, the warmer it will be when it exits. A longer hose may allow you to increase the volume of water traveling through the hose and warm the pool more quickly.

Does the hose have to be black?

NO! Any dark colored hose will work. Of course the darker the hose the better it will capture the solar heat from the sun. 

How long does it take to heat the pool?

This is a difficult question to answer because there are so many variables. The very first requirement is SUN. Hose color, length and positioning are other variables that play a huge role in the amount of heat you achieve. For example, a dark hose on cement will produce better results than a green hose on grass. Another major factor is the volume of water traveling through the hose. If the volume of water is too large, the water will move through the hose too quickly and not be heated. We recommend a stream of roughly ½-inch diameter to produce a good temperature.

Will it damage the pump?

When used properly, this Device has little if any effect on pump operation. At no time should the Device totally obstruct the flow of water to the pool; even in the closed position water is directed to the hose outlet. Compared to the stress a pool vacuum places on a pump, you shouldn’t notice any difference in your pool operation.
