| Atlantic High School |
| This job had 480 vertical bores, which went down 133 feet each. Using the 63,840 vertical feet of bore at 157 vertical feet per ton, it provided 407 tons of capacity, which was used by 67 Trane heat pumps ranging from 1 to 66.5 tons. On this project, we were not required to install any form of supplemental heat. |

| Iowa State Wallace Foundation Research Farm |
| This project incorporated three separate horizontal loop fields. Between the three loops, we had 11 separate heat pump circuits totaling 43 tons. This project used 11 Water Furnace heat pumps with push/pull pump packages. Three of the units incorporated electric strip heat in the supply ductwork to supplement the heat pump. |

| Corning Elementary School |
| This project was a geothermal retrofit. It has 102 vertical bores going down 200 feet each. With 20,400 vertical feet of bore, the 130 tons of load requires 155 vertical feet per ton. This project is using 23 Water Furnace heat pumps. One of these units provides kitchen hood makeup air so it does incorporate electric strip reheat in the outside air ductwork. The school incorporates three energy recovery units. These units are placed through out the school and provide tempered makeup air to the remaining heat pumps. |

| Adair - Casey School System |
| This project was a geothermal retrofit. It has 108 vertical bores going down 200 feet. Having 21,600 vertical feet of bore, the 267 ton of load used 81 vertical feet per ton. This project used a combination of Carrier and WaterFurnace to make up the 106 heat pumps. This project was completed during the summer break and was ready for school that fall. The facility had three energy recovery units and two boilers installed for backup heat for the ground loop. |

| Jim Grizzard |
| This residential project incorporated a pond as the heat exchanger. We installed 4 tons of coiled pipes into the 1 acre pond. The pond was 15 feet deep a the loop position. This installation has performed excellently. The pond is 100 yards away from the house. |
| |
| Nishna Valley YMCA |
| This project has 190 vertical wells going down 95 feet. Fifteen heat pumps, one natatorium unit and three energy recovery units are using this footage. This creates a load of 129 vertical feet per ton. This project is total geothermal. |
| |
| Pinnacle Construction |
| This project was an outside system repair. The existing horizontal loops were inadequate and did not carry the load. We installed 14 wells going down 200 feet each. |
| |
| Corning Ridgeview Apartments |
| This was also an outside system repair. The existing horizontal loops were inadequate for the 12 unit building load. We installed 6 wells going down 250 feet and combined the remaining loops into 6 systems. |
| |
| Creston Middle School |
| It will incorporate 384 wells going down 200 feet. This will create 344 tons of capacity used by 103 Carrier heat pumps. These units range in size from 1/2 to 13.5 tons. The field has a load of 223 feet per ton. |

| Trevor Blanchard |
| This was a residential installation in an addition/remodel house project. It has 2250 square feet of space handled by a WaterFurnace 4-ton, 2-speed, E-Series unit. This unlit has environmentally friendly 410-A refrigerant gas. The ground exchanger consist of 4 extended horizontal slinkys installed 6 feet deep. |
| |
| Gary Longfellow |
| This was a remodel/addition project for a home owner. After completion, the house has 2650 square feed handled by a WaterFurnace 5 ton, Premier 2, 2-speed unit. We installed 5 extended horizontal slinkys through out the yard, running 6 feet deep. |
| |
| Atlantic Home 2002 |
| This new home was 2500 square feet on the main floor with a walk out basement. We installed a 6 ton WaterFurnace E-Series 2-speed unit with a zoning system and an energy recovery ventilator. The upstairs was divided into two zones and the basement was the third zone. This job consisted of a vertical ground heat exchanger with thermally enhanced grout. |
| |
| Villisca Home |
| This customer wanted to replace his older existing ground source heat pump. We installed a new WaterFurnace E-Series, 2-speed Unit. We used the existing ground loop for the new unit. |
| |
| Shenandoah Home |
| We replaced an existing air to air heat pump with a WaterFurnace E-Series, 2-speed Split System. The existing gas furnace is still used a s the auxiliary heating source. The ground loop consists of a horizontal slinky system. |
| |
| Atlantic Home 2003 |
| This was a new home built in Atlantic. It was approximately 2300 square feet on the main floor with a walk out basement. We installed a 6 ton WaterFurnace unit with a vertical ground heat exchanger. |
| |
| Dexter Home |
| In this new home we installed a 4 ton WaterFurnace Premier unit with a 2 pipe horizontal ground heat exchanger. The customer worked for an excavation contractor so he took care of the trenching and backfilling. |
| |
| Lake Panorama Home |

| |
| Atlantic Home 2004 |
| This countryside home gave us plenty of room to install a horizontal ground heat exchanger. We used an extended slinky loop for this 5 ton system. The unit selected was a 5 ton WaterFurnace E-Series 2-speed Unit. Also implemented to this system were an energy recovery ventilator and a zoning system. |
| |
| Randy Watts Home, Atlantic, IA |
| This was a replacement project. Randy replaced his existing gas furnace and air conditioner with a WaterFurnace E-Series 2-speed Unit. He used a vertical heat exchanger system on this project. |
| |
| Griswold Home |
| The customer wanted to replace his existing electric/oil furnaces and update to air conditioning at the same time. We installed a 5 ton WaterFurnace E-Series 2-speed Unit. This was an open loop system. The existing well was used as the discharge well and the new well was the source well. |
| |
| Pymosa School/Atlantic Head Start |
| We took out the existing propane furnace and installed 15 WaterFurnace console units on this job. There is now a total of 21 tons of geothermal capacity in the school. Each unit has its own independent well. there are two units in each of the classrooms and they are staged on by one thermostat. |

| Indianola Home |
| The home on this property was very close to their pond. We utilized the pond by installing a pond loop. Inside we replaced the existing propane furnace with a WaterFurnace E-Series 2-speed Unit. |
| |
| Massena Home |
| We replaced a 19 year old 3 ton ground source heat pump with a WaterFurnace Premier 2 unit. The unit was still operational. The homeowner wanted to upgrade the equipment and wanted to take advantage of the increase in the efficiency of ground source heat pumps over the past 19 years. |
| |
| Brayton Home |
| This installation used the existing gas furnace as the auxiliary heating system. We added a 4 ton WaterFurnace E-Series Split System to the furnace and installed a horizontal ground heat exchanger. |
| |
| Corning Home |
| The customer in this home wanted to eliminate the existing radiant ceiling panel heating and replace the air conditioning system. We installed a 4 ton WaterFurnace Dual Speed E-Series Unit with a horizontal ground heat exchanger. We also tied the desuperheater feature on this unit into the domestic hot water heating system. |
