- Q?What are the benefits of using a geothermal heat pump to heat and cool my house or business?
A Geothermal heat pump is:
- In new building construction it provides a positive cash flow from day one when costs are rolled into your mortgage.
- Retro-fitted to your existing home, the Return on Investment is typically four to seven years when you replace your furnace and air conditioning unit at the same time when they reach the end of their life. Consult a geothermal heating and cooling professional for exact information about your project.
- Efficient: Operational costs are lower since the geothermal unit exchanges heat with the ground rather than the air.
- Energy savings of 30-50% over typical air source heat pumps is due to a more moderate ground temperature than air temperature.
- Savings are even greater when compared to oil, propane or electric resistance heating.
- Environmentally Safe:
- Clean: No fossil fuels are needed. Electricity powers the system—efficiently.
- Quiet. There is no noisy outdoor unit. The equipment inside the house is designed to be ultra-quiet.
- Safe: No open flame or chimney is required. No odors, carbon monoxide (CO), carbon dioxide (CO2), flammable or volatile fumes or particulates are produced.
- Comfortable: The delivered air temperature is closer to body temperature, so you feel no hot or cold spots in the building.
- Eligible for PSEG LI rebates.
- Eligible for federal tax credits, for both residential and commercial properties.
- Eligible for EPact tax deductions on commercial properties.
- Underground: No noisy outdoor unit that must be worked into the landscaping. Bore holes for closed loop and direct exchange systems can be installed under driveways and parking lots. Supply and diffusion wells for open loop systems can be hidden in landscaping or buried under the lawn.
- Compatible with existing forced air systems.
- Ideal for radiant floor heating.
- Flexible: Can be installed in both new and retrofit situations.
- Multi-purpose: One geothermal unit can provide heating, cooling, domestic hot water and hot water for radiant heating. FREE domestic hot water is provided through a desuperheater, a hot water accessory which reclaims the heat going back to the ground and instead places it into the hot water supplying kitchens, bathrooms and anyplace else there is a hot water tap.
- Smart investing since it hedges against any future fossil fuel price increases.
- Worry-free: No concern about scheduling fuel deliveries and fluctuating oil, propane and natural gas prices.
- Q?Doesn’t geothermal need a lot of space? What are the lot size requirements on a residential retro-fit?
In general, the minimum lot size is 500 square feet of free outdoor lawn area to an eighth acre (5500 square feet) for most homes. There needs to be a minimum side clearance of 15 feet so that drilling/excavation equipment can get into the backyard. An installing contractor or well driller can evaluate your individual site to let you know about site specific conditions and whether you have enough land to install a geothermal heating and cooling system.
- Q?What are the steps in installing the geothermal heating and cooling system?
There are three basic steps:
- Excavation or drilling
- Installation of piping and any other underground equipment
- Installation of inside equipment
- Q?Are there other financial advantages to using a geothermal heating and cooling system?
In addition to the PSEG LI rebates for installing a geothermal heat pump and federal incentives in the form of tax credits and tax deductions, PSEG LI offers On-Bill Financing to help you finance your new geothermal heating and cooling system, if needed.
PSEG LI also has a NY Energy Star® Labeled Homes incentive program for new homes and re-builds. Most municipalities on Long Island require new homes to be built to Energy Star standards. If your home exceeds your municipality’s Energy Star requirements you may qualify for this cash incentive.
PSEG LI uses the Home Energy Rating System (HERS) Program to determine the amount of the incentive. Often, a geothermal heating and cooling system will boost your score—and rebate— significantly.
