If you are exploring the heating and cooling options for a new house or commercial building, or looking for ways to reduce your energy bills, you may be considering a Geothermal (Geo-Exchange) heat pump. A heat pump can provide year-round climate control for your home or building, supplying heat in winter and cooling in summer. Some models can also provide domestic hot water.
At Hub Well Drilling we are pleased to offer services pertaining to the "Loop" portion of the Geothermal System. When conditions permit and groundwater is plentiful, an "Open Loop" system is typically the most affordable option. In this situation water is pumped from one well through the heat pump which uses the geothermal energy of the water for heating or cooling, and is then discharged into a second well. This system not only supplies for the heating and cooling of a house, but will also serve to provide the domestic water for the house.
In situations where an abundant water supply is not available, a "Vertical Closed Loop" system is another viable option. In this type of system multiple boreholes are drilled (depth and quantity of holes vary based on heating / cooling load), and 1 continuous pipe with a U-bend on the bottom is installed inside. Once the "Loop" is installed, the well is filled from the bottom of the borehole to the surface with a non permeable bentonite grout using a high pressure grout pump. These vertical loops act as large heat exchangers which serve to absorb or disperse heat, depending on heating or cooling modes. These casings and pipes are later cut off below grade and fused together and then piped into the home. The final results of these systems take up no space and can be buried below a driveway or yard.
