Just 10 feet below the frost line, the ground is a constant 55 degrees Fahrenheit year round.
Even when the air outside is below freezing.
Or on the hottest summer days.
Dandelion Geothermal harness this difference in temperature between the ground and the outside air to heat and cool your home.
The system is made up of two basic parts:
A heat pump that sits inside your home (typically where the furnace used to sit)
Underground pipes, called ground loops, installed below the frost line
A water-based solution circulates through the closed underground pipes where it absorbs the heat from the ground.
The 50 degree mixture is pumped into the heat pump where it is transformed into a vapor. The vapor enters the compressor where its temperature is raised by increasing the pressure — forcing the vapor into a small space.
Once this is complete, the vapor enters a heat exchanger where it transfers its heat to the air. This hot air is then distributed through the home’s ductwork.
In cooling mode, the system works in reverse where the ground acts as a “heat sink” instead of a heat source. The 55º ground easily accepts the heat being transferred from your home.
A geothermal heating and cooling system is basically made up of two parts: a geothermal heat pump that sits inside the home, and one or two underground pipes called “ground loops” that are installed in the homeowner’s yard.
Heat pumps do exactly what their name suggests: they use electricity to pump heat from one place to another. A refrigerator is an everyday example. To keep your food and drinks cold, your fridge uses electricity to pump heat from the inside of the refrigerator to the outside air. A geothermal heat pump works similarly: in the summer, when you want your home nice and cool, it moves heat from inside your home into the earth; in the winter, when you want your home warm and toasty, the pump moves heat from the earth into your home.
The ground loops are U-shaped plastic pipes, inserted 300 to 500 feet into the ground, that are used to exchange heat between your house and the earth. In the wintertime, water circulating through the ground loops absorbs heat from the earth, which is used to warm your home, and in the summertime your home is cooled by transferring the heat from your home into the earth.
Dandelion’s geothermal heating and cooling system replaces your existing heating, cooling and hot water equipment. The system includes a heat pump (roughly the same size as a furnace), water heater and smart thermostat which are each installed inside your home. The system also includes ground loops, or U-shaped plastic pipes, that are inserted a few hundred feet below the ground outside of your home.
The complete system is installed in two to three days. First the ground loops are installed in the yard by drilling one or two vertical holes just a few inches wide to depths of a few hundred feet. Ground loops are U-shaped plastic pipes that are used to exchange heat between your house and the earth. Dandelion has designed a clean drilling technology, so there will be minimal disruption to the yard. Finally, the heat pump, water heater and smart thermostat are installed inside of your home by a technician in just a few hours.
First check if Dandelion is available in your area; please visit our homepage and enter your zipcode. Dandelion will conduct an assessment that will inform you of how much money you’re likely to save by switching to Dandelion’s home geothermal system.
For qualified homeowners, Dandelion offers a home geothermal heating and cooling system for $20,000. Dandelion is partnering with a leading financing company to enable homeowners to switch to home geothermal energy with zero upfront costs and low monthly payments.
Geothermal heating and cooling is the cleanest and most efficient heating and cooling technology on the market. Because the system taps into a renewable resource, the earth, your heating and cooling source will never run out and monthly bills are predictable. An average homeowner who uses oil or propane to heat the home spends $2,500 a year on heating fuels, which averages to almost $210/month. With Dandelion's zero-down installation, homeowners can expect to pay less.
Dandelion’s home geothermal heating and cooling system simply requires changing the air filter in your home every 6 to 12 months. You’ll also be able to monitor the performance of your Dandelion system online.
The typical lifespan of a geothermal heat pump is 25 years. Closed-loop piping typically lasts for at least 50 years.
The Dandelion system is available to qualified homeowners in 11 counties in New York state: Dutchess, Ulster, Columbia, Greene, Rensselaer, Albany, Schenectady, Schoharie, Saratoga, Montgomery and Fulton.
