Horizontal Loops These are often considered when adequate land surface is available. Pipes are placed in trenches that range in length from 100 to 400 feet. Click on the loop diagram to see it enlarged.
		Vertical Loops These are the ideal choice when available land surface is limited. Drilling equipment is used to bore small-diameter holes from 75 to 300 feet deep. Click on the loop diagram to see it enlarged.
		Pond (Lake) Loops These are very economical to install when a body of water is available, because excavation costs are virtually eliminated. Coils of pipe are simply placed on the bottom of the pond or lake. Click on the loop diagram to see it enlarged.
		Open loops These use groundwater as a direct energy source. In ideal conditions, an open-loop application can be the most economical type of geothermal system. Click on the loop diagram to see it enlarged.

Geothermal systems are extremely energy efficient since they only need a relatively constant, renewable energy source, and use it for heating, air conditioning and hot water.

Geothermal systems circulate a water-based solution through a "loop" of small diameter, underground pipes. When heating, this solution absorbs heat from the ground which results in a small amount of electricity being used to power the pump, compressor and fan. Geothermal systems typically deliver up to four times more energy than they consume, so you save money on your monthly energy bills when compared to other types of heating and cooling systems.

WHY IS WATERFURNACE THE SMARTER CHOICE? Simply put, a WaterFurnace geothermal heating and cooling system is: 1. an investment in affordable comfort and, 2. an investment in the preservation of our environment for generations to come. The secret of a WaterFurnace system's clean, efficient operation is the earth's ability to store heat. In fact, 47 percent of the sun's energy that reaches our planet is absorbed into the earth. That's 500 times more energy than all of humanity would need in a year! And it's an unlimited source of energy. Installing a WaterFurnace system in a typical home is the environmental equivalent of planting 750 trees-or taking two cars off the road. That's because WaterFurnace systems don't burn fossil fuels, and they don't emit carbon dioxide, which has been associated with the greenhouse effect and global warming.

The Geothermal Heat Pump Consortium says current geothermal systems save more than 14 million barrels of crude oil every year. And because the only energy needed to run geothermal systems is a small amount of electricity, they reduce the need for new coal-powered electric power plants. Result? Cleaner air and less acid rain.

A MAJOR ADVANTAGE: FOUR TIMES THE EFFICIENCY

A WaterFurnace system uses the Earth's thermal properties in conjunction with electricity to provide unprecedented efficiency. For every unit of electricity the system uses, it provides four units of heating energy, giving a geothermal system a 400 percent efficiency rating, on average. These numbers can translate into real savings on your utility bills year-round.

The WaterFurnace Advantage

When you invest in a WaterFurnace system, you can be assured that you're receiving the highest-quality, best-performing heating and cooling system available. Here are some of the benefits of WaterFurnace ownership.

Lower Operating Costs

A WaterFurnace system operates more efficiently than ordinary heating and air conditioning systems-30 to 60 percent more efficiently, in most cases.

Comfort

Because a WaterFurnace system uses the relatively stable temperature of the earth as an energy source, you're assured of constant, even winter heating and better humidity control in summer.

Safety With a WaterFurnace system, there are no flames, no flues and no odors. There's no danger of combustion, fire or carbon monoxide poisoning, either. What you get is safe, reliable operation year after year. Clean Operation A WaterFurnace system minimizes environmental threats linked to fossil-fuel burning, including acid rain, air pollution and the greenhouse effect. Quiet Operation A WaterFurnace system is designed and manufactured to be exceptionally quiet. It will run as quietly as your refrigerator or freezer. Flexibility A WaterFurnace system provides heating, central air conditioning and hot water, all from the same compact unit. Economical Water Heating Water heating can be a significant energy expense. A WaterFurnace system can reduce the high cost of water heating by as much as 66 percent.

Good Looks

The completely self-contained indoor WaterFurnace system needs no noisy, unsightly outside condensing unit. Your neighbors won't have any cause for complaint.

Great Warranties

In the unlikely event of a service problem, WaterFurnace systems are backed by the industry's best 10-year parts and labor warranty.
