    Your investment in a WaterFurnace system will provide you with many years of benefits including: Energy Savings WaterFurnace units deliver 3 to 4 units of energy for every 1 unit of energy consumed. Many homeowners experience energy savings from 30% to 60% over other ordinary heating and cooling systems.

  • Page 7: About Your Waterfurnace System

    ABOUT YOUR WATERFURNACE SYSTEM ABOUT YOUR WATERFURNACE SYSTEM This section includes some detailed information about how geothermal technology works, and how the different compo- nents used in the system work together to provide you with the finest comfort system available. You'll find useful informa- tion about the refrigeration process, loop systems, safety, and warranties.

  • Page 8: How Geothermal Systems Work

    ABOUT YOUR WATERFURNACE SYSTEM HOW GEOTHERMAL SYSTEMS WORK The Interesting Basics… Geothermal heat pumps utilize some of the same technology found in your home's refrigerator. They are both devices that move heat energy. Your refrigerator removes heat from the food and transfers it to the air in your home.

  • Page 9: Heating Mode

    ABOUT YOUR WATERFURNACE SYSTEM Heating Mode During heating, a geothermal system absorbs the heat from the ground via the earth loop. The heating cycle starts as cold, liquid refrigerant passes through the water-to-refrigerant heat exchanger (coax, and also the evaporator during heating).

  • Page 10: Cooling Mode

    ABOUT YOUR WATERFURNACE SYSTEM Cooling Mode During cooling, a geothermal system rejects the heat from the indoor air into the earth loop. The cooling cycle starts as cold, liquid refrigerant passes through the air coil (the evaporator during cooling). As the refrigerant flows through the air coil, the heat energy transfers from the warm return air to the refrigerant.
  • Page 11 ABOUT YOUR WATERFURNACE SYSTEM Hot Water Assist Many geothermal units installed in homes have an optional feature called a hot water generator. This component re- moves excess heat from the refrigerant circuit and adds it to a hot water circuit in the unit. For more information refer to page 47.

  • Page 12: Typical Installation & Components

    ABOUT YOUR WATERFURNACE SYSTEM TYPICAL INSTALLATION AND COMPONENTS Your geothermal system is actually a collection of components working together to perform the heating, cooling and water heating functions. The basic system includes the unit, power supply, a control component, the water circuit and a distribution method.

  • Page 14: Closed Loop Systems

    ABOUT YOUR WATERFURNACE SYSTEM Closed Loop Systems Horizontal Loops Horizontal earth loops are used where the space allowed for the loop is not extremely limited. There are various designs of horizontal loops. There is not one type of horizontal loop that is best for every application.

  • Page 15: Your Loop Location

    ABOUT YOUR WATERFURNACE SYSTEM Your Loop Location It is strongly recommended that you have a record of the location of your earth loop. Using the grid below, draw a bird’s eye view of the property where the loop is located. Include the house and measurements from various points so that there is no question about the location of the piping system.

  • Page 16: Open Loop Systems

    ABOUT YOUR WATERFURNACE SYSTEM Open Loop Systems Open Loop or Well Water Systems An alternative to closed loops are open loop systems, also known as well-water systems. If your system is an open loop, it uses water that comes into your home from your well. Water from the well is circulated through the unit whenever the unit is heating or cooling.

  • Page 17: Safety Warnings

    ABOUT YOUR WATERFURNACE SYSTEM Safety Warnings WARNING: Equipment used for heating, air conditioning and water heating can cause injury if safety precautions are not observed. These systems generally use a 230 volt power supply which is double the voltage used by other household appliances. Electrical shock from these systems could cause personal injury or death.
