Ground-source heat pump is the name for a broad category of space conditioning systems that employ a geothermal resource – the ground, groundwater, or surface water – as both a heat source and sink. GSHPs use a reversible refrigeration cycle to provide either heating or cooling.
GSHPs operate in much the same manner as air-source heat pumps. Both use a compressor to move refrigerant around a closed loop, transferring heat between an indoor coil and another coil where heat is absorbed or rejected. As the name implies, an air-source heat pump (ASHP) uses outside air, flowing over its outdoor coil, as the heat source and sink. The main drawback of ASHPs is that their performance depends on ambient air temperature, which can vary by as much as 100o F over a year. Both the capacity (i.e., the ability to produce heating and cooling) and efficiency of an ASHP are significantly reduced at the extreme temperatures experienced in summer and winter.

What is a Vertical Heat Exchanger?
|
|
|
|
|
|
|
The heat exchanger usually consists of one or two u-tubes through which the carrier fluid, usually water, circulates. The space around the u-tubes is filled with groundwater or backfilled with thermally conductive grout.

What are the environmental advantages of geothermal?
|
|
|
|
|
|
|
- Reduces the electrical consumption of traditional Heating, Ventilation and
Cooling (HVAC) systems using clean, green, sustainable and renewable energy.
- Financial Benefits... energy costs lowered by up to 70%
- Demand side management delivers recurring financial benefits
- Ground Source Heat Pumps (GSHP) significantly reduce energy consumption
- GSHP can deliver air-conditioning (heating, cooling and hot water) within one
system
- GSHP utilizes low grade geo-thermal energy to replace traditional HVAC
systems

Currently installed systems are making a huge difference in our environment! Geothermal systems are eliminating more than three million tons of carbon dioxide and are equivalent of taking 650,000 automobiles off the road. Geothermal systems conserve energy and, because they move heat that already exists rather than burning something to create heat, they reduce the amount of toxic emissions in the atmosphere. They use renewable energy from the sun, and because the system doesn't rely on outside air, it keeps the air inside of buildings cleaner and free from pollens, outdoor pollutants, mold spores, and other allergens.

How much will a geothermal system cost to install?
|
|
|
|
|
|
|
The initial investment for a GSHP system is greater than that of a conventional system. However, when you consider the operating costs of a geothermal heating, cooling, and water
|
|
|
|
How long will it take for my system to pay for itself?
|
|
|
|
|
|
|
This answer is based on what it would cost you to operate another heating and cooling system as compared to how much your bills will be lowered operating a geothermal system. An energy analysis which will show the cost of operating a geothermal system as compared to a conventional system and how long it will take for the savings to cover the cost of the system completely. With natural gas users we typically see a payback of approximately 5-10 years and with propane we are seeing as quickly as 2-5 years!

What size system will I need?
|
|
|
|
|
|
|
We recommend that if you are strongly considering going with a geothermal system, you should have a heat load calculation done on your home. This gives us the information we need to properly size your geothermal system and give you the most efficient system to meet your needs.

What are the major benefits to installing geothermal?
|
|
|
|
|
|
|
The GSHP is one of the most efficient residential heating and cooling systems available today, with heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners. That directly translates into savings for you on your utility bills.
