Geothermal Heating Systems are an effective and efficient way of heating and cooling your home or building.
According to the US Department of Energy, approximately 50,000 ground source heat pumps are being installed in the United States each year, and for good reason. To start with, these systems have proven to require from 25 to 50% less energy over conventional systems, with the earth providing over 70% of the HVAC energy. Statistics like these are hard to ignore, and if you've never imagined conditioning your facility from the ground, read on.
Very simply, a geothermal HVAC system uses the consistent temperature of the earth only 4 to 7 meters down, or under a pond. The system will extract the earths warmth in the winter to heat a building and will transfer the buildings extra heat in the summer to the cool earth. This system is very quiet and fully contained in the building which eliminates exterior compressors and heavy roof top units. Both the EPA and DOE have publically endorsed the technology for both new construction and retrofits of older buildings. The geothermal heat pump (GHP) has few moving parts and since it is located indoors GHP's have warrantees of 20 to 25 years, and the underground pipes 25 to 50 years. Building water can also be heated pre heated in the summer by this system meaning water heating cost and space required for equipment is much less.
Also called ground source heat pumps (GSHP)'s are encouraged by the US Green Building Council with the reward being LEED credits in multiple categories. The technology is being used in hospitals, government buildings, schools, high rises and any commercial building owner looking to lower operation and maintenance costs. Since GHP's are electric many users are able to eliminate multiple utility types, and eliminate boilers and chillers all together. These systems are able to maximize efficiencies with the flexibility of room to room zones and the ability to reduce peak demand loads. Due to smart metering policies out west and soon coming east, "peak load" avoidance strategies for all building owners will soon become highly important.
Unfortunately, at this time, installation of a GHP may have higher up front expenses but will quickly cost justify with less infrastructure, or maintenance needs and reduced energy requirements. The Geothermal Exchange Organization (GEO) is also lobbying and is looking for support to have this valuable resource considered as "renewable energy". Without this valuable label ground source systems are not eligible for the 2005 Energy Policy Act requiring that by year 2013 7.5% of the energy used by the federal government be from renewable sources. Since GHP's capture a thermal form of unlimited renewable ground energy that can be measured, metered and verified the GEO organization is also asking that their technology be included in the Clean Energy Standard (CES) legislation. This inclusion would encourage retail utility support, as power companies attempt to fulfill ever increasing renewable energy requirements. Many retail power providers eager to meet their states CES requirement are offering on bill financing for energy upgrades. Often the payment for the improvement is lower than the amount of monthly energy saved. Sound energy ideas such as these are creating American jobs, reducing foreign dependence and can dramatically reduce the carbon pollution believed to increase global warming. Are you Paying for Air?
Yes you are... we all are. We pay for the tiny bubbles mixed in with our incoming supply from the water utility. This air has always been a natural component to turbulent rushing water and as it passes through the meter it registers and you pay for it. In fact you pay for it twice because your incoming meter read is used to determine both water and sewer expense. Fortunately new technology has provided an answer to this dilemma. It is based on 18th century principals from Le Chatelier and the Venturi effect. The reduction of this incoming air through the meter can reduce meter spin by 10 to 25%. This device is able to compress the air before it passes through the meter although its placement is after the meter. The flow management system utilizes a oscillation assembly to create the air compression. Among other things this system will disrupt the usual swirl turbulence in the line without reducing flow. The device does not vent the air from the line but it does effectively compress it. The product is accepted by most municipalities and completely safe and sanitary. Because this technology is scalable it makes excellent sense for the large or small water user and will show impressive ROI.
