Geothermal Heat Pump Types

There are 4 various types of geothermal heat pumps offered today.

Each one has a various technique of attaching to the home heating circulation system in your house or structure. Some kinds are more effective than others at supplying room conditioning to the building, however that is a property of the distribution.

Every one of these GSHP kinds still get their energy from the ground loophole, which transfers the soaked up heat into the interior cooling agent loop. It’s what occurs to the heat after that is what makes the difference in between types.

The four different types of geothermal heat pumps are water to air, water to water, combination as well as split heatpump.

Water to Air

The very first and also most likely most utilized geothermal heatpump is the water to air heatpump. This heat pump is utilized for houses with forced air systems, as well as essentially changes a traditional heater. The ground loop brings in absorbed heat to the refrigerant loop (the water section of “water to air”). That refrigerant is after that pressed and also cycled before a fan coil device to be sent via duct distribution to the house (the air section of “water to air”. This procedure can also be changed in reverse to supply cooling down to a structure.

One feasible style issue is the sizing of the ductwork. Because geothermal systems are thought about a reduced temp warmth source, a higher volume of air is needed to supply the exact same heating or cooling lots. This will certainly either require bigger ductwork to suit for the greater air quantity, or a specialized, small-duct, high-velocity forced air system like Unico or SpacePak.

Water to Water

The second type is a water to water, or hydronic. This type operates the like all other heat pumps on the ground loop side of the refrigerant, however as opposed to sending the pressed and also heated up cooling agent to a follower coil, it is transferred directly right into one more water loop that flows through the heatpump, as well as right into the water-based circulation. This hydronic circulation is most frequently induction heat (Glowing as well as Geothermal Post), yet it can likewise be used together with a residential hot water or an outside snow melt system.


The third type is a combo system. This combines the previous two heat pumps, supplying both forced air and also hydronic circulation. This is perfect in houses or buildings where both types of distribution are needed. Some areas might be extremely high warm loss, such as areas with big home windows, or near a leave door that is regularly open, and will need more warm in the area than simply radiant or just required air might give. This is where a combination system providing both might can be found in really handy.

The last kind of pump on the market is called a split heat pump. This kind is primarily the same as a normal heat pump on the water side, but it sends the refrigerant in a long loop to a remote air handler. This makes it simpler in larger work to maintain the geothermal device in the mechanical area with all the loop area connections, as well as still have an air handler delivering warm to a difficult to get to area, such as the 2nd tale of a large house. This enables better adaptability in the overall layout of the heating distribution system. Read more info on heat pumps by going to this link,
