You will find four differing kinds of geothermal heat pumps available today.

Every one has another way of connecting to your heating distribution technique in your house or creating. Some sorts tend to be more successful than Many others at delivering House conditioning towards the constructing, but That may be a home of the distribution.

These GSHP types however get their Electrical power from the ground loop, which transfers the absorbed warmth into The inner refrigerant loop. It's what transpires to the warmth following that is exactly what would make the difference between varieties.

The four differing kinds of geothermal heat pumps are water to air, h2o to water, combo and split heat pumps.

Drinking water to Air
The main and probably most used geothermal warmth pump could be the drinking water to air warmth pump. This warmth pump is useful for homes with pressured air methods, and essentially replaces a conventional furnace. The bottom loop delivers in absorbed heat on the refrigerant loop (the h2o percentage of "water to air"). That refrigerant is then compressed and cycled before a lover coil device being despatched by way of duct get the job done distribution to your house (the air part of "drinking water to air". This method will also be switched in reverse to deliver cooling to the framework.

1 feasible style and design situation could be the sizing of the ductwork. For the reason that geothermal units are regarded as a minimal temp warmth supply, a greater quantity of air is necessary to provide a similar heating or cooling load. This will likely possibly involve larger sized ductwork to support for your better air quantity, or a specialized, small-duct, large-velocity compelled air system like Unico or SpacePak.

H2o to H2o
The next variety is often a drinking water to h2o, or hydronic. This sort capabilities the same as all other heat pumps on the bottom loop side from the refrigerant, but as an alternative to sending the compressed and heated refrigerant to the fan coil, it is actually transferred straight into A further drinking water loop that circulates through the warmth pump, and in to the h2o-based mostly distribution. This hydronic distribution is most often radiant heat (Radiant and Geothermal Posting), but it can even be utilized at the side of a domestic very hot water or perhaps a outside the house snow soften program.

Combo
The 3rd sort is often a combo unit. This combines the previous two heat pumps, delivering each pressured air and hydronic distribution. This is perfect in houses or buildings exactly where both equally types of distribution are wanted. Some zones may be extremely higher heat reduction, like rooms with major Home windows, or near an exit doorway that is continually open up, and would require much more heat within the Place than simply radiant or just pressured air could supply. This is when a combo device providing both equally could are available extremely handy.

The final variety of pump available on the market is named a break up warmth pump. This type is essentially the same as a daily heat pump to the h2o side, but it really sends the refrigerant in a long loop to a distant air handler. This causes it to be less difficult in larger Careers to keep the geothermal device from the mechanical area with all of the loop industry connections, and however have an air handler warmtepomp deurne providing warmth to a hard to succeed in location, including the second story of a big house. This enables for increased overall flexibility in the overall structure of your heating distribution process.
