A water source heat pump system is different from a soil source heat pump system in that it is an open cycle that uses water from a well to heat or cool your home. In the summer, it will drain your home's heat into the water, and in the winter, it will transfer the heat from the water to your home.
In the past few years, open water source heat pump system loops were common, but after a period of operation, the closed soil source heat pump system loop now dominates. This is partly due to significant improvements in the technology of the soil source heat pump system, in part due to the environmental and geological problems associated with the excessive use of water source heat pumps in some areas. Up to now, the water source heat pump system is still a good choice if you pass the EIA and get the water permit.
Over time, the heat exchanger of the water source heat pump system needs to be cleaned, but it will increase the cost of later use. The frequency of cleaning required will determine if such wells are available. In most cases, it is best to use a closed water source heat pump loop to reduce the inconvenience of cleaning the source heat pump loop.
The pumping cost of the well also affects the availability of the water source heat pump system. The main cost of pumping well water is that the well water is lifted to the main engine room under the action of the water pump. At this time, there is a requirement for the power of the pump. If the well water is deep and the distance is long, the pump power is larger; otherwise, the smaller the flow. In addition to pump power, there is one that is the cost of the pump. A stable and efficient pump will also cost a lot.
