The Solar Pool Heater by Hammacher Schlemmer is a simple device to heat the water of an above ground pool without incurring any energy bill costs.
The Solar Pool Heater is designed to be attached to a pump-operated filtering system, it takes the water from this and passes it through its 6 meters (20 feet) of coiled black piping. This piping is housed into the device to make the heater only measure 58.5 cm x 58.5 cm x 25.5 cm (23 in. x 23 in. x 10 in.). It is this black piping that heats the water, exposed to the sun this piping heats up in the sunlight, warming the water that is passing through it effectively. this warmed water is then fed back into your pool.
Obviously this type of heating will not make a drastic change in temperature of a pool, but it will help take away the chill. It is estimated that the pool heating system increases the temperature of a 6,000 gallon (2271 liter) pool by 5º F (around 3º C) in 10 days. Up to 4 of these heaters can be connected to the one pool at once to speed up the heating process. By only using the heat from the sun there is no long tern running costs for this heater, though obviously it will be ineffective on cold cloudy days.
The Solar Pool Heater comes with all the hardware and accessories needed to connect it to your above ground pool and its pump-operated filtering system. It also comes with a protective cover to protect the heater while it is in storage over the cooler months.
The solar pool heater retails for $199.95 plus shipping.
