What Questions Should You Ask of
Ground Source Heat Pump Suppliers?
 

 

There are quite a few ground source heat pump suppliers in the industry and sometimes it is difficult to pick the best company for your extensive project.  However, choosing the best ground source heat pump system simply involves measuring your precise land area and determining the right technology for your budget. 

How the Installation by Ground Source Heat Pump Suppliers Works

Geothermal heat pumps operate in a special manner that is a hybrid between solar technology and traditional HVACs.  They collect heat from the earth.  The sunlight is stored in the ground and a complex system set up underneath the land exploits the heat.  In winter, the pump system stores the heat and uses it to heat the interiors of property.  In summer, the system stores hot waste and exchanges the heat for cooler temperatures by dissipating it into the surrounding air and using refrigerant tools.  

The cost that ground source heat pump suppliers charge will be high, as you are not only paying for the underground parts, but also the piping and ductwork—and these details will depend on the total size of your house.  Naturally a smaller home would require less material and fewer hours of labour, and would be less pricey than a huge business property.  The larger the area, the more heating and cooling it will require.  Hence, it’s not merely about the size of the ground source heat pump, you also have to factor in insulation.

Ground Source Heat Pump Suppliers Can Offer You Specific Options

Next, you must decide what the appropriate set up is for your home or business.  For instance, there is the direct exchange geothermal heat pump, which is the most common form and the easiest.  It operates by a single loop circulating refrigerant which comes into contact with the ground. 

Another type of system is the closed loop style, which has two loops on the ground side and has the refrigerant loop in a cabinet where it exchanges heat with the second water loop that is located under the ground.  Another option to mull over is the vertical closed loop field, which is constructed in a vertical fashion and runs many feet deep into the land.  In contrast, the horizontal setup has a slinky loop constructed first, and then covered in soil afterwards.  These loops run out horizontally.  There is also radial drilling which involves laying pipes underneath the land without disrupting surroundings, and the pond-style system, which involves using the body of water in a pond loop manner. 

All of these closed loop styles are different from the open loop system, which pumps water from a nearby source into a heat exchanger which is contained inside the pump.  
The standing column well is another type of open loop system, but this is drawn from a deep rock well, and then flows through a pump and to the top of the well structure.

If you are interested in a ground source heat pump, suppliers are waiting to discuss your options.  Why not start saving money by using this natural and sustainable power that surrounds you?


How It All Works

Before we discuss how the geothermal pump works, we need to look at a geothermal heating system. It is interesting to note that the modern designs have been in use since the 1940s, but have only really “taken off” in terms of installation in homes over the past few decades.

A geothermal heating (and cooling) system is actually very basic and easy to understand. It helps to consider it by its other name which is a “ground source heating system”. This means that the heat is pulled from the ground via a cleverly designed “closed loop” system of pipes that are buried in the ground beneath a home or property. These pipes contain water or a refrigerant that is circulated through, and which pull the existing heat from, their surroundings. The heat is circulated back up through the pipes where the warm liquid from the ground is passed in front of a fan or blower unit.

The fluid remains contained within the pipes at all times (hence the “closed loop) and the fan simply blows air around the pipes to force the heat into the ductwork. This is an overly simplified explanation of how geothermal works, but it does help to give you a good idea of the total absence of traditional energy supplies for a large portion of the system.
