Why Geothermal & Geothermal Applications

  • Low Operating Cost

    For every one unit of electrical energy used, geothermal systems can deliver between 3-6 units of heat energy. That translates into an efficiency rating of 300-600%! By combining stored earth energy with safe electric power, many homeowners realize savings up to 70% for heating, cooling and hot water.

  • Enhanced Comfort

    You’ll love how your geothermal unit eliminates hot and cold spots in your home. No more temperature spikes in winter. No more damp, humid air in the summer. For ultimate comfort, you can even install a zoning system, which uses multiple thermostats to precisely control temperatures in areas of your house.

  • Environmentally Friendly

    A geothermal system emits no carbon dioxide, carbon monoxide or other harmful greenhouse gasses which are considered to be major contributors to environmental air pollution. With the system, you can take comfort in a better environment.

  • Safe & Clean

    Since neither natural gas, propane, oil or wood are required to operate a geothermal unit, there is no combustion, flames or fumes and no chance of carbon-monoxide poisoning.

  • Reliable

    Unlike conventional air conditioners and heat pumps, geothermal units are installed indoors, so they are not subject to wear and tear caused by rain, snow, ice or extreme temperatures. WaterFurnace geothermal units have proven to be very reliable and require less maintenance than conventional heat pumps. Thus, overall furnace life cycle costs are far lower with geothermal.

  • Versatile

    Geothermal units are versatile. We can install a system in your home, whether new, old, large or small. Although most systems are simply single units in a forced air application, geothermal systems can also be used for many other types of installations.

  • Radiant Floor Heating

    Some geothermal units can provide hot water for radiant floor applications, utilizing tubing encased in the floor. By circulating warm water through the tubing, the room is comfortably conditioned. Since the entire floor acts as a giant radiator, you’ll experience consistent comfort throughout the room from head to toe. Floors are kept toasty warm, even with bare feet. And with individual thermostats in every room, you can control which rooms you want a little toastier.

  • Domestic Hot Water

    Do you have a large demand for domestic hot water? When equipped with the hot water assist option, your geothermal unit can deliver preheated water to your hot water heater. The longer the unit operates, the more hot water is generated. Over the course of a year, your geothermal unit can make up to 60% of your hot water. 

  • Pool Heating

    Geothermal units can also be utilized to heat water for pools and spas. You’ll find a geothermal system will heat your indoor pool or spa for much less than an ordinary pool heater. And compared to fossil fuel burning heaters, it’s much safer too, without the concerns associated with carbon monoxide poisoning.

  • Commercial Applications

    In addition to being a smart choice for residential installations, many commercial and institutional buildings utilize geothermal systems. We have the experience to implement geothermal to any realistic application.

How Geothermal Works & Basic Components

What is geothermal heating and cooling? How does it work?

Throughout the year, almost 50% of the sun’s energy is absorbed into the earth where it maintains a consistent temperature just a few feet below the ground’s surface. Geothermal technology takes advantage of this constant renewable energy source by combining a series of loops installed outside underground with a heat pump system inside that looks very similar to a conventional furnace. This combination of high performance technology allows us to tap into the earth’s natural heating and cooling properties to consistently and evenly distribute warm or cool air in your home or office throughout each season.

An environmentally friendly antifreeze solution or pure water carries energy directly from the closed or open loop system into the heat pump inside your home or office. In the winter, the heat pump acts as a furnace, distributing the heat throughout your home using the system’s heat exchanger and compressor. In the summer, it acts as an air conditioner, collecting the heat from your home and distributing it into your domestic hot water tank or back into the earth through the loop system.

Not only can a geothermal system provide you with year round indoor comfort, it can also provide inexpensive domestic hot water, supplementing or replacing your conventional domestic hot water heater.

It doesn’t matter whether you live in the country or in the city, there is a geothermal solution that will work for every building type and every climate condition.

A geothermal heating and cooling system (sometimes called a ground source heat pump) is usually made up of three main parts: a ground loop, the heat pump (furnace) and the distribution system (ductwork or in-floor pipes).

The ground loop is built from polyethylene pipe which is buried in the ground outside your home either in a horizontal trench (horizontal loop), through holes drilled in the earth (vertical or directional drilled loop) or submerged in a pond or lake.

A pump circulates liquid (the heat transfer fluid) through the loop and to the heat pump located inside the home. The ground source heat pump extracts heat from the ground and distributes the heat collected from it throughout the home. The chilled liquid is pumped back into the loop and, because it is colder than the ground, is able to draw more heat from the surrounding soil. These loops are often referred to collectively as a closed loop, as the same liquid circulates through the closed system over and over again.

Another way is to pump ground water or well water directly through the heat pump. A geothermal system that uses ground water is often referred to as an open-loop system. The heat pump extracts heat from the well water, which is usually returned to the ground in a return well. To run an open-loop geothermal system, you need a reliable well with water that contains few dissolved minerals that can cause scale build-up or rust over the long term, as it is pumped through the heat pump´s heat exchanger.

In both cases, a pump circulates liquid through the loop and the heat pump. The heat pump chills (or collects the heat stored in) the liquid when it is being used as a source of heat, and circulates it back through the loop to pick up more heat. A system for a large home will require a larger heat pump and ground loop, with a circulation pump to match.

After the geothermal system has taken the heat energy from the ground loop and upgraded it to a temperature usable in your home, it delivers the heat evenly to all parts of the building through a distribution system. It can use either air or water to move the heat from the heat pump into the home.

Types of Ground Loops

Horizontal Trench Loops

img_horizontal_loopIf adequate land is available, horizontal ground loops can be installed. Based on the size of equipment needed, one or more trenches are dug using an excavator or chain trencher. Polyethylene pipes are inserted in the trench at a depth of roughly 5 feet and then the trenches are backfilled. There are various designs of horizontal loops, using any number of circuits in a trench. Trenches normally range from 100 to 300 feet long depending on the design. A typical home requires ¼ to ¾ of an acre for the trenches.

Costs: Inexpensive  Time: 1 Day   Disruption: Moderate

Directionally Drilled (Horizontal Bore) Loops

img_horizontal_bore_loopsWhere there is adequate space for a horizontal ground loop, but there is a desire to minimize disruption on the surface, the horizontally drilled ground loop would be the preferred solution. This loop type uses directional drilling equipment to bore holes horizontally under the surface. Our machine has the capability to start at the surface and drill at an angle down to a depth of roughly 10 feet, then drill back to the surface about 300 feet away. At that point two ends of pipe are attached to the end of the drill bit and are pulled back through the hole to the header. This technique allows the ground loop to be placed underneath homes, septic beds, wooded lots or even swimming pools. The only digging required is for the header trench, where all of the pipes are joined together.

Buchanan & Hall has been installing ground loops with our own directional drilling equipment for over 3 years now. During this time, we have done extensive testing on the efficiency of this type of ground loop and found that these loops perform amazingly when compared to conventional loops.

Costs: Inexpensive  Time: 2-5 Days  Disruption: Minimal

Vertical Bore Loops

img_vertical_bar_loopsVertical ground loops are used where space is limited or where obstacles permit a horizontal style of loop. Installing vertical loops requires the use of a drilling rig. Multiple holes are bored about 10 feet apart. A double pipe connected with a U-bend is inserted into each hole. The hole is filled with grout to provide good contact around the pipe and to seal the hole. The vertical pipes are then connected to a header system horizontally a few feet below the surface. The depth of the holes is dependent upon soil/rock conditions and the size of the system being installed. The only digging required is for the header trench where all of the pipes are joined together.

Costs: Moderate  Time: 2-5 Days  Disruption: Minimal

Open Loop (Water Well) System

img_open_loop_systemIf an abundant supply of quality well water is available, an open loop system can be installed. A proper discharge site, such a stream, a pond or another well from the same aquifer, must also be available. If you already have the proper set up, this installation usually costs less to install and delivers the same high efficiency as a regular ground loop.

Costs: Inexpensive  Time: 1 Day (for discharge line)   Disruption: Minimal
