You can find four different types of geothermal heat pumps currently available.

Every one has a special method of connecting on the heating distribution procedure in your house or creating. Some types are more effective than Other folks at providing House conditioning into the building, but That could be a residence of the distribution.

Most of these GSHP sorts nevertheless get their Electricity from the bottom loop, which transfers the absorbed warmth into The interior refrigerant loop. It really is what happens to the heat after that is what makes the difference between varieties.

The 4 different types of geothermal warmth pumps are drinking water to air, h2o to water, combo and split heat pumps.

H2o to Air
The first and possibly most utilized geothermal warmth pump is definitely the h2o to air warmth pump. This warmth pump is employed for homes with compelled air systems, and mainly replaces a traditional furnace. The ground loop delivers in absorbed warmth for the refrigerant loop (the h2o part of "drinking water to air"). That refrigerant is then compressed and cycled in front of a enthusiast coil device for being despatched via duct do the job distribution to the house (the air part of "drinking water to air". This method will also be switched in reverse to deliver cooling to your structure.

A single achievable design and style difficulty may be the sizing from the ductwork. Mainly because geothermal techniques are thought of a small temp heat source, an increased quantity of air is required to deliver precisely the same heating or cooling load. This may either demand greater ductwork to accommodate for your increased air quantity, or a specialized, compact-duct, substantial-velocity pressured air program like Unico or SpacePak.

H2o to Drinking water
The second kind is actually a water to h2o, or hydronic. This sort capabilities similar to all other warmth pumps on the ground loop side of the refrigerant, but in place of sending the compressed and heated refrigerant to your fan coil, it is actually transferred straight into An additional h2o loop that circulates in the warmth pump, and in the water-primarily based distribution. This hydronic distribution is mostly radiant heat (Radiant and Geothermal Write-up), but it really will also be employed at the side of a domestic very hot h2o or even a outdoors snow soften process.

Combo
The third sort can be a combo device. This combines the former two warmth pumps, furnishing equally pressured air and hydronic distribution. This is perfect in residences or structures exactly where both of those different types of distribution are essential. Some zones could be extremely high heat loss, for instance rooms with huge windows, or warmtepomp deurne close to an exit doorway that is continually open, and will require additional heat during the House than simply radiant or simply just pressured air could supply. This is when a combo unit providing both equally could can be found in quite useful.

The last style of pump in the marketplace is named a break up heat pump. This sort is basically the same as a daily warmth pump over the water aspect, nevertheless it sends the refrigerant in a lengthy loop into a distant air handler. This causes it to be a lot easier in bigger Employment to maintain the geothermal device during the mechanical place with each of the loop field connections, and even now have an air handler delivering heat to a tough to reach position, such as the next story of a large property. This enables for bigger adaptability in the overall style with the heating distribution procedure.
