You need a fairly complex system to be evaluated on an energy system in terms of economic feasibility and engineering feasibility.
A system can be described in terms of matter by looking at the particles it contains, such as atoms and molecules. In terms of energy, a system can be described by the energy it possesses or exchanges with its surroundings, including potential energy (due to position or composition) and kinetic energy (due to motion). Together, the matter and energy within a system contribute to its overall properties and behavior.
No, heaters are not 100 efficient in terms of energy consumption. Some energy is lost as heat escapes from the system, reducing overall efficiency.
An isolated system is a system in which neither matter nor energy can enter or leave the system. This means that no interactions with the surroundings can occur in terms of energy or matter exchange. The total energy and mass within an isolated system remain constant.

The Earth is essentially a closed system in terms of matter because very little matter enters or leaves it. While energy from the sun does enter the Earth, matter such as air, water, and rocks primarily remain on the planet. However, the Earth is not a closed system when considering energy because it receives energy from the sun and releases energy back into space.
The universe is generally considered to be an isolated system in terms of energy, but not in terms of matter. This means that energy cannot enter or leave the universe, but matter can. The universe is constantly expanding and evolving, allowing for interactions within its boundaries.
Earth is an open system when it comes to energy, as it receives energy in the form of sunlight from the sun and emits energy back out into space. This constant input of energy drives the Earth's climate, weather patterns, and sustains life on the planet.

Water cycle is the term for the constant movement of the earth's water from oceans to air to land and back to oceans
A PTAC system is typically less efficient than a mini-split system because it uses more energy to heat or cool a room. Mini-split systems are more energy-efficient and provide better performance in terms of temperature control and air quality.
When energy input is equal to energy output, the system is said to be in a state of equilibrium. This means that the system's energy levels remain constant and there is no net change in energy over time. In other words, the system is balanced in terms of energy flow.
