2. EXPECTED SAVINGS Savings vary by region and energy costs Savings happen large or small homes Natural gas prices today are artificially low –Consumers must be educated on the volatility –Comparing 60 cents gas vs 9 cents electric is minimal Propane is down but an easier target market Show your customer the savings over the next 5, 10 & 15 yrs The tax credit plays a big part when gas prices artificially droop 2

3. THE COMFORT OF GEOTHERMAL SYSTEMS Geothermal systems provide even temperatures throughout the home (when properly installed) Most systems are dual stage which provides more run time Most gas furnaces are on/off/on/off. Geothermal systems do not dry out the air in the heating mode. In cooling, geothermal systems provide better dehumidification (the coil temperature is lower and longer run times). 3

4. 4 Design and Sizing Overview “The best geothermal heat pump on the market can appear to be a poor choice to the homeowner if its design and/or installation are not correct for the application.” Key to Efficient, Reliable System – Consider the best unit for each project Packaged Split Water-Water Combination Two-stage or Single Stage www.enertechmfg.com4

5. HOW TO CHOOSE A HEAT PUMP Must be- –AHRI rated/certified –ETL listed –Energy Star rated Should have- –High EER’s, high cooling capacity –High COP’s, high heating capacity 5

6. HOW TO CHOOSE A HEAT PUMP There are several good brands to choose from. The supplier should also be an important consideration when choosing a heat pump. When you’ve decided on the brand/supplier what else is there…………………. 6

7. Geothermal Heat Pumps Configurations Water to Water –Chill or Heat Water most diversified Water to Air –Most common, usually central plant one zone Split systems –Similar to an Air to Air Heat Pump with a Line set Combo Systems –Does water to water, and water to air but only one at a time 7

8. PROPER INSTALLATION PRACTICES Proper Model Nomenclature to place an order –A misplaced letter or number could be the wrong unit Installation Considerations –What would be a good location for the unit Dimensional, Physical and Electrical Data –Size and power requirements for the installation Piping, Ducting, and Antifreeze –All three affect the performance of the installation Desuperheater Suggested Procedures

9. 9 Cautions and Warnings –The most important item on the job is you. The warnings and cautions are posted to protect you. Ignoring or disregarding these warnings could lead to serious injury or possibly death –Using equipment during the construction phase will void warranty I(installation) O(operation) & M(maintenance) Manual

10. Pre-Installation 10 Be sure what you order is what you receive! All equipment must be stored in a dry location All equipment must be installed indoors. Be sure to remove all packaging materials before start up. Check all electrical connections for tightness Check all refrigerant lines for kinks or damage The equipment with the longest service life are those installed and started up properly.

11. Unit Access & Placement Air Pad 2 foot distance suggested around entire unit for service 11

12. All supply and return plenums should have flex canvas collars All metal duct in an unconditioned location should be insulated Units are considered low velocity systems 400 CFM per ton of nominal cooling capacity Main Duct System Practices 12

13. 13 Ductwork Considerations www.enertechmfg.com13 Branch duct or takeoff should be at least 24” from any reducer Branch duct takeoff should be at least 24” from any reducer Blower Return Supply Reducer Takeoff should be at least 24” from an end cap Flex connector Insulation can be added to the supply plenum and return drop to help reduce noise An elbow with 500 CFM or more or airflow should have turning vanes

14. Loop Install & Air Purging The most common issue with a newly installed system. –Proper loop field design is critical Loops must be with in 5% length of each other Reverse Return Reducing Header Large enough Flush & Purge Cart Patience (allow enough time for air purge) 14

15. Equal Loop Length by Reverse Return 15 This loop depicts the Reverse Return or First Out – Last In
