|  | 1. | Entering water temperature has a significant effect on heat pump operating efficiency. 
 
 | 
|  | 2. | Instead of a furnace and air-conditioner, you might have a heat pump. 
 
 | 
|  | 3. | You can do this if the heat pump serves only your unit. 
 
 | 
|  | 4. | This process acts as a heat pump, transporting warm equatorial water North. 
 
 | 
|  | 5. | Standard ARI 870 ratings are intended for direct exchange ground-source heat pumps. 
 
 | 
|  | 6. | Note that the COP of a heat pump depends on its duty. 
 
 | 
|  | 7. | The expansion will be heated and cooled by a geothermal heat pump. 
 
 | 
|  | 8. | This, however, can actually reduce the efficiency of the heat pump. 
 
 | 
|  | 9. | Geothermal heat pump systems are more expensive initially than conventional systems. 
 
 | 
|  | 10. | The design of a heat pump has a considerable impact on its efficiency.
