Geothermal Heating

What is Geothermal Deep Lake Water Cooling? Though the widespread use of passive geothermal energy is relatively recent, the promise of drastically reducing heating and cooling costs could make homes so efficient that they hardly need to use any extra energy for those functions. Of these heat exchange systems, the most efficient are those that use deep lake water for heating and cooling.

Such systems can come in one of two types: those that draw and discharge into the body of water directly (though, more often, though a filtration system) and those that simply plunge the water or glycol carrying pipes into the lake for a bath in the almost constantly temperate deep waters.

Though frigid to the typical swimmer, these waters are a far sight warmer than most winter days in much of North America and Europe. That means they can be used to bring up the base temperature from which a home or business must be heated to a nearly comfortable 45-50° F (or 8-10° C), greatly reducing the need for heating fuel.

Similarly, in the summer the lake continues to remain cool at depths, allowing the cool water that circulates to directly cool the floor and foundation that otherwise collects warmth throughout summer days. This, coupled with simple warm air management and thermal curtains can cut the cooling bill in most buildings to nearly nothing, even in very warm climates. Deciduous trees on the south side of your home or business are also very helpful in assisting with temperature control during the winter and summer months.

The open systems that discharge into ponds, lakes or rivers will likely need to be cleared first with a local, provincial, state or regional governmental body before you can legally proceed, whereas the closed loop systems do not discharge when working correctly and are not commonly regulated. Those who live in modern, North American housing developments may have to present their ideas to a neighbourhood council, primarily for aesthetic and property valuation reasons.

Deep lake water cooling and heating systems are most commonly employed in somewhat rural areas where people have access to at least a few acres (more than one hectare) on which a suitable pond or lake may be located. Those who make the initial investment in the materials and installation will find immediate and observable results as soon as the water begins to flow. This type of geothermal technology is best suited to farms, resorts and public buildings.
