Wherever you live, the temperature beneath your home remains constant regardless of the season. ClimateMaster^® Geothermal Heat Pump Systems harness the stable underground temperature to provide heating, cooling, and hot water at remarkably high efficiencies. So high, in fact, that energy use can be cut by up to 80%. As the world’s largest and most progressive leader in clean, renewable geothermal technology, ClimateMaster leads the way with its award-winning Tranquility Series geothermal heat pumps.

As the world’s largest and most progressive leader in the industry, ClimateMaster offers a complete line of heating and cooling systems that can lower utility bills, improve indoor air quality, reduce environmental impact and keep you comfortable for years to come.

Using the Power of the Earth

Nearly half the solar energy our planet receives is absorbed by the ground.

As a result, below the surface the earth remains a constant moderate temperature year-round. This provides an ideal source for heating and cooling your home. Geothermal systems use a sealed underground piping loop filled with circulating water and an ultra high-efficiency Tranquility heat pump to exchange heat between your home and the earth.

In the winter, the earth is your source of heat.

Water circulating in the piping loop absorbs heat from the earth and carries it to the heat pump, where it is concentrated and sent as warm, comfortable air throughout your home.

In the summer, the earth is your source of cooling.

The heat pump absorbs heat from the air in your home and transfers it to water circulating in the piping loop where it is absorbed by the earth. This provides cool, dehumidified and comfortable air throughout your home.

Unlike traditional systems that use the air to heat and cool your home, ClimateMaster^® systems circulate water through a system of sealed underground piping loops that carry heat to and from the earth to the system. In the heating mode, the system uses the heat from the water to warm air that circulates throughout the house. In the cooling mode, the system reverses the process, taking heat out of the home’s air and circulating the resulting cool, dehumidified air instead.

Because the system has less work to do to reach the desired temperature setting throughout the year, the system is highly efficient and lowers operating costs. A fossil fuel furnace may be 80% to 90% percent efficient; a geothermal heat pump is amazingly 450% efficient.

Another advantage to a geothermal system installed in a new home is that from day one you will be cash flow positive, as the cost of the system each month is lower than the savings you realize on your monthly energy cost!

The Tranquility 27™ (TT) Series blends the most advanced technology with the most advanced design to create the most efficient Water-Source Heat Pump of any manufacturer, anywhere on the planet.

The TT Series utilizes EarthPure™ HFC-410A refrigerant along with the Copeland UltraTech™ two-stage compressor and General Electric ECM variable speed motor to bring unmatched performance and comfort.

The Tranquility 27™ (TT) Series is eligible for additional LEED™ (Leadership in Energy and Environmental Design) points because of the “green” technology design.

The opposite of anxiety… is Tranquility™. Homeowners just like you are growing more anxious every day as energy prices fluctuate wildly. Even worse, no permanent relief is in sight.

What can you do to protect your family from this costly trend? Reduce your consumption of energy. You can improve your home’s “energy efficiency” with improved appliances, more insulation, and newer or fewer windows… but, did you know that over 50% of your utility costs come from heating, cooling, and water heating? Now, that’s something you can control… it's called the Tranquility™ geothermal system from ClimateMaster.

Using EarthPure™ Ozone Safe Refrigerant*, the Tranquility™ is a breakthrough in efficiency – providing you with the greatest energy savings of any space conditioning system and unprecedented environmental protection at the same time. The Tranquility 27™ with two-stage compressor and variable speed fan, and the single stage Tranquility 20™ offer the latest in geothermal technology.

The Tranquility 27™ is the highest efficiency water-source heat pumps on the planet offering an unprecedented 27EER* to 31EER**

Advantages

Low Utility Bills: Components and design so highly evolved make Tranquility™ the most efficient energy saver anywhere.
Flexibility: You get heating, central air conditioning, and domestic hot water... three important benefits from a single compact unit.
Comfort: Tranquility 27™ automatically adjusts to satisfy changing weather conditions by using advanced Two-Stage compressors and variable speed air delivery system that responds to your comfort needs.
Safe and Clean: Geothermal heating and cooling has no flame, no flue, no odors, and no danger of fumes.
Homeowner Satisfaction: Independent consumer surveys rate geothermal systems as having the highest customer satisfaction compared to other types of heating and cooling systems.
Noise-Free Operation: Unlike traditional air conditioners or heat pumps, geothermal units have no noisy outdoor fans to disturb you or your neighbors.
System Performance Monitor: Automatic alert system let's you know if the system is not running at peak performance.**
Long System Life: The elegant yet durable design of the Tranquility™ series ensures long life, dependable operation and low maintenance. All Tranquility™ air coils are specifically treated for longevity.
MERV 11: Superior air filtration improves indoor air quality. Compared to traditional fiberglass air filters, the MERV 11 removes up to 9 times more dust, lasts 3 times longer and captures nearly 100% of pollen and spores.

Two-Stage Comfort

The Tranquility 27™ is so sophisticated it automatically adjusts itself to provide the optimum, consistent indoor air temperatures regardless of the weather extremes.

Advanced Two-Stage Technology allows the Tranquility 27™ to operate at the most efficient level for all weather conditions. The Tranquility 27™ has the industry’s highest efficiency ratings.

Advanced two-stage design allows the Tranquility 27™ to “match” performance to meet all weather conditions:

On those cold winter days the second stage automatically engages when needed to keep your home warm and comfortable.
During the hottest months the second stage automatically engages when needed to provide additional cooling.
In mild spring and fall months only the first stage is needed to provide optimum indoor comfort.
Ninety percent of the year the Tranquility 27™ runs on low stage. The second stage kicks in automatically only when needed in the hottest and coldest months of the year. Using an electronic variable-speed fan motor, the Tranquility 27™ assures you of high comfort, maximum efficiency, superior year-round dehumidification, and low utility bills.

The energy-efficiency criteria for geothermal heat pumps to qualify for the Energy Star program requires an EER rating of 14.1 (closed loop systems) or 16.2 (open loop system). The Tranquility 27™ (two-stage) has a EER rating of 27; the Tranquility 20™ (single stage) has a EER rating of 20 – showing that not all Energy Star qualified systems are equal.

Tranquility 27™. The most energy efficient space conditioning system available from any manufacturer, anywhere on the planet.
