What are the savings? GHPs consume 25–50 percent less electricity compared to conventional HVAC equipment, so installing one is a great green home remodeling project. In other words, a GHP needs only one unit of electricity to move three units of heat compared to a ratio of 1:1 or 1:2 for other systems. GHPs can decrease energy consumption and the accompanying emissions by as much as 44

Because of the technical knowledge and equipment needed to properly install the piping, a GHP system installation is not a do-it-yourself project. To find a qualified installer, call your local utility company, the International Ground Source Heat Pump Association or the Geothermal Heat Pump Consortium for their listing of qualified installers in your area. Installers should be certified and

Geothermal heat pumps save money in operating and maintenance costs. While the initial purchase price of a residential GHP system is often higher than that of a comparable gas-fired furnace and central air-conditioning system, it is more efficient, thereby saving money every month. For further savings, GHPs equipped with a device called a "desuperheater" can heat the household water. In the

The heating efficiency of ground-source and water-source heat pumps is indicated by their coefficient of performance (COP), which is the ratio of heat provided in Btu per Btu of energy input. Their cooling efficiency is indicated by the Energy Efficiency Ratio (EER), which is the ratio of the heat removed (in Btu per hour) to the electricity required (in watts) to run the unit.

The ground heat exchanger in a GHP system is made up of a closed or open loop pipe system. Most common is the closed loop, in which high density polyethylene pipe is buried horizontally at 4-6 feet deep or vertically at 100 to 400 feet deep. These pipes are filled with an environmentally friendly antifreeze/water solution that acts as a heat exchanger.There are four basic types of ground loop

This type of GHPS uses well(s) or surface body water as the heat exchange fluid that circulates directly through the Geothermal heat pump system (GHP). Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local

Large commercial buildings and schools often use vertical systems because the land area required for horizontal loops would be prohibitive. Vertical loops are also usedwhere the soil is too shallow for trenching, and they minimize the disturbance to existing landscaping. For a vertical system, holes (approximately four inches in diameter) are drilled about 20 feet apart and 100 to 400 feet deep.

Horizontal closed-loop type of installation is generally most cost-effective for residential installations, particularly for new construction where sufficient land is available. It requires trenches at least four feet deep. The most common layouts either use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot

If the site has an adequate water body, this may be the lowest cost option. Asupply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface to prevent freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.

Basic physics for those considering a heat pumpMost people are familiar with heat pumps, and know that they can provide both heating in the winter and cooling in the summer. They also know that heat pumps are considered to be a very efficient way of heating a structure, since they draw heat from the outside air. But many people also wonder how a heat pump works to draw out that heat, and how low

To figure this accurately, you must know how much per year you'll save in energy costs with a geothermal system and the difference in costs between it and a conventional heating system and central air conditioner. As an example: If you'll save $700 per year with a geothermal system and the cost difference is $2,000, your payback will be less than three years.

FAQ: Will open or closed-loop be best for you?That depends on several factors, as stated earlier. A dealer should be willing to install what's best for you, not for him.FAQ: Will the loop joints be heat fused?The only acceptable method for joining sections of the special pipe used for closed-loop systems is heat fusion. Any other method will eventually result in failure of the loop.

Yes. If you have an open-loop system, your entering water temperatures may range from the 70s in the southern United States to the 40s in Canada. All heat pumps can handle temperatures in the moderate to warm ranges. A closed-loop system, on the other hand, will encounter EWT's below freezing. Not all geothermal heat pumps will operate efficiently at those temperatures. It's important for you to

All types of heating and cooling systems have a rated efficiency. Fossil fuel furnaces have a percentage efficiency rating. Natural gas, propane and fuel oil furnaces have efficiency ratings based on laboratory conditions. To get an accurate installed efficiency rating, factors such as flue gas heat losses, cycling losses caused by over sizing, blower fan electrical usage, etc., must be included.

Furnaces are designed to provide specific amounts of heat energy per hour. The term 'Btuh’ refers to how much heat can be produced by the unit in an hour. Before you can know what size furnace you'll need, you must have a heat loss/heat gain calculation done on your home. From that, an accurate determination can be made on the size of the heating system you'll need. Most fossil fuel furnaces are

Regardless of the type of heating system you may be considering for your home or business, there are specific questions you should ask the dealer installer. These questions deal with finding out the actual efficiency of the system, any operating limitations it may have, and the bottom line of operating costs. The answers here are meant as a guide for what you should try to find out with your

The net results in operating cost and efficiency are virtually the same. Which system to choose depends mainly on whether you have an adequate groundwater supply and means of disposal. If you do, an open loop can be used very effectively. If not, either a horizontal or vertical closed-loop system is your best choice. Over a period of years, a closed-loop system will require less maintenance

A geothermal heat pump system moves warm air (90 degrees - 105 degrees) throughout your home via a standard duct network. Typically, a very even comfort level is found throughout the home. This is because the warm air is moved in slightly higher volumes and, therefore, saturates the home with warmth more evenly. This helps even out hot or cold spots and eliminates the cold air blast common with

A system for the typical home will cost more than if you bought a separate furnace and central air-conditioning system. But you wouldn't really be comparing apples to apples. To get an accurate comparison of costs you need to consider the following:• Payback or how long it takes to recover the difference in costs between the two systems using energy savings. Payback for most geothermal heat-pump

Your contractor should provide a heating and cooling load calculation (heat loss, heat gain) to guide your equipment selection. Geothermal heat pumps are sized to meet your cooling requirements. Depending on your heating needs, a geothermal heat pump will supply 80 to 100 percent of your design heating load. Sizing the heat pump to handle your entire heating needs may result in slightly lower

Most units are easy to install, especially when they are replacing another forcedairsystem. They can be installed in areas unsuitable for fossil fuel furnaces because there is no combustion, thus, no need to vent exhaust gases. Ductwork must be installed in homes that don't have an existing air distribution system. The difficulty of installing ductwork will vary and should be assessed by a

Yes. Using what's called a desuperheater, some types of geothermal heat pumps can save you up to 50 percent on your water heating bill by preheating tank water. Desuperheaters are standard on some units, optional on others. Some geothermal models can provide all of your water needs on demand at the same high efficiencies as the heating cooling cycles.

No. There are different kinds of geothermal heat pumps designed for specific applications. Many geothermal heat pumps, for example, are intended for use only with higher temperature ground water encountered in open-loop systems. Others will operate at entering water temperatures as low as 25 degrees F which are possible in closed-loop systems.Most geothermal heat pumps provide summer air

Q: What is an open-loop system?The term "open-loop" is commonly used to describe a geothermal heat pump system that uses groundwater from a conventional well as a heat source. The groundwater is pumped into the heat pump unit where heat is extracted, and then the water is disposed of in an appropriate manner. Since groundwater is a relatively constant temperature year-round, it is an excellent

Q. What is a closed loop system?The term "closed-loop" is used to describe a geothermal heat pump system that uses a continuous loop of special buried plastic pipe as a heat exchanger. The pipe is connected to the indoor heat pump to form a sealed, underground loop through which an antifreeze solution is circulated.

Q. You mentioned heating and cooling - does it do both?One of the things that makes a heat pump so versatile is it's ability to be both a heating and cooling system in one. You can change from one mode to another with a simple flick of a switch on your indoor thermostats. In the cooling mode, a geothermal heat pump takes heat from indoors and transfers it to the cooler earth through either

Q. How is the heat transferred between the earth and home?The earth has the ability to absorb and store heat energy from the sun. To use that stored energy, heat is extracted from the earth through a liquid medium (groundwater or an anti-freeze solution) and is pumped to the heat pump or heat exchanger. There, the heat is used to heat your home. In summer the process is reversed and indoor heat
