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.
