As used in this chapter, the following terms shall have the
meanings indicated:
ANNULAR SPACE
The space between the casing or well screen and the wall
of the borehole or between drilling pipe and casing or between two
separate strings of casing.
BOREHOLE
A hole drilled or bored into the earth, usually for exploratory
or economic purposes; a hole into which casing, screen, and other
materials may be installed to construct a well.
CASING
An impervious, durable pipe placed in a borehole to prevent
the walls of the borehole from caving, and to seal off surface drainage
or undesirable water, gas, or other fluids and prevent entrance into
the well.
CLOSED-LOOP GEOTHERMAL BOREHOLE
A boring(s) drilled to facilitate the installation of a pipe
loop for a ground source heat pump system whether circulating water,
heat transfer fluid, or refrigerant using direct exchange.
CLOSED-LOOP GEOTHERMAL HEATING/COOLING SYSTEM
A closed or sealed system designed to heat and/or cool a
dwelling or building which circulates water, heat transfer fluid or
refrigerant through underground loops. The loops are installed either
in closed-loop boreholes or horizontally in trenches or ponds and
exchange heat with the ground.
GEOTHERMAL HEATING/COOLING SYSTEM
A mechanism for heat exchange which consists of the following
basic elements: underground loops of piping, heat transfer fluid,
a heat pump, and air distribution system.
GEOTHERMAL WELL
A well(s) installed for the purpose of heating and/or cooling
the dwelling or building on a property.
GEOTHERMAL WELL INSTALLATION CONTRACTOR
Any individual in immediate supervision of and/or responsible
for the drilling of boreholes used for the purpose of geothermal heating
and/or cooling of a dwelling or building. This individual is responsible
for, among other things, boring, closed-loop geothermal pipe installation,
and grouting of boreholes.
HEAT EXCHANGER
A device, usually consisting of coils of pipe that transfers
heat from one medium to another; for example, from water to air or
water to water.
HEAT TRANSFER FLUID
Any liquid used specifically for the purpose of transferring
thermal energy from its source to another location.
OFF-GRID
That which is not connected to the public electric utility.
ON-GRID
That which is connected to the public electric utility.
OPEN-LOOP GEOTHERMAL HEATING/COOLING SYSTEM
An open or unsealed system designed to heat and/or cool a
building which uses a ground water supply well to extract groundwater
which is passed through a heat pump and into any discharge well or
other area.
SMALL WIND ENERGY SYSTEMS
Any device, structure or electronics that converts wind energy
into usable electrical energy through the use of a wind turbine, a
tower, and associated control or conversion electronics.
SOLAR ENERGY EQUIPMENT
Any device, structure or electronics that converts solar
energy into usable electrical energy, or uses solar energy to heat
liquids or produces hot air or performs any similar function through
the use of solar panels.
SOLAR PANEL
A device containing one or more receptive cells equal to
or greater than two square feet, the purpose of which is to convert
solar energy into electrical or thermal energy.
WIND TURBINE
A wind turbine is a machine which converts the kinetic energy
in wind into electricity.
