There are actually 4 differing kinds of geothermal heat pumps available today.

Each one has a different means of connecting for the heating distribution procedure in your house or creating. Some types are more effective than Some others at providing space conditioning for the constructing, but That may be a assets of your distribution.

Every one of these GSHP types nevertheless get their Vitality from the bottom loop, which transfers the absorbed warmth into the internal refrigerant loop. It is really what happens to the warmth following that is exactly what will make the distinction between types.

The 4 differing types of geothermal warmth pumps are h2o to air, h2o to h2o, combo and break up warmth pumps.

Water to Air
The main and doubtless most utilised geothermal warmth pump would be the h2o to air heat pump. This heat pump is used for houses with compelled air devices, and mainly replaces a traditional furnace. The ground loop provides in absorbed heat towards the refrigerant loop (the h2o part of "drinking water to air"). That refrigerant is then compressed and cycled before a fan coil device to get sent as a result of duct get the job done distribution to the house (the air part of "drinking water to air". This method can be switched in reverse to offer cooling to the structure.

Just one probable layout concern may be the sizing with the ductwork. Since geothermal devices are regarded a very low temp warmth source, an increased volume of air is necessary to provide precisely the same heating or cooling load. This will both need much larger ductwork to accommodate for that larger air quantity, or a specialized, modest-duct, significant-velocity forced air technique like Unico or SpacePak.

Drinking water to Water
The next form is really a drinking water to water, or hydronic. This sort features similar to all other heat pumps on the bottom loop side on the refrigerant, but as opposed to sending the compressed and heated refrigerant to a lover coil, it can be transferred directly into One more h2o loop that circulates with the warmth pump, and to the h2o-dependent distribution. This hydronic distribution is most often radiant heat (Radiant and Geothermal Article), but it can be utilised at the side of a domestic warm drinking water or possibly a exterior snow melt program.

Combo
The third form is really a combo unit. This combines the previous two warmth pumps, providing both of those compelled air and hydronic distribution. This is ideal in residences or structures in which both of those forms of distribution are desired. Some zones might be extremely significant warmth loss, for instance rooms with large Home windows, or near an exit doorway that is constantly open up, and would require a warmtepomp deurne lot more warmth in the Room than just radiant or simply compelled air could provide. This is where a combo unit providing both equally could can be found in pretty helpful.

The final kind of pump on the market is called a split heat pump. This type is essentially the same as an everyday warmth pump on the drinking water side, but it surely sends the refrigerant in an extended loop to some remote air handler. This can make it much easier in more substantial Careers to help keep the geothermal unit inside the mechanical area with each of the loop field connections, and however have an air handler delivering heat to a hard to succeed in location, including the 2nd story of a large home. This permits for larger flexibility in the overall style and design of the heating distribution method.
