A heat pump is a device that transfers thermal energy from a cool region to a warm one. It does this by using a refrigeration cycle to extract heat from the cool source and release it into the warm sink.
In gases and liquids, thermal energy is transferred through a process known as convection. This involves the movement of the molecules within the substance, transferring heat from one region to another. Warmer, less dense regions rise, while cooler, denser regions sink, creating a circulation pattern that transfers thermal energy.
heat is the transfer of thermal energy because of difference in what?
Yes, thermal energy can be transferred through conduction (direct contact between materials), convection (through fluids like air or water), and radiation (electromagnetic waves). This transfer of thermal energy occurs from a high-temperature region to a low-temperature region until thermal equilibrium is reached.
The process by which thermal energy moves from a region of higher temperature to a region of lower temperature is called heat transfer. This can occur through three main methods: conduction, convection, and radiation.
Thermal energy is lost to the outside air due to conduction, convection, and radiation. Heat energy naturally flows from a higher temperature region to a lower temperature region, so the furnace loses some of its thermal energy to the cooler surrounding environment. Adequate insulation and sealing can help minimize these losses.

I think you're talking about a heat engine or heat mover..

The name for the thermal energy transferred only from a higher temperature to a lower temperature is heat. Heat naturally flows from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached.

Since the late 60s/early 70s, heat has been considered as energy in transit from a body at a higher temperature to one at a lower temperature. Heat is directly comparable to work, where work describes energy in transit from one form into another.So, heat and work both describe transfers of energy, not energy itself.We can use water as an analogy. When it's vapour, we call it a 'cloud', when it condenses, we call it 'rain', when it's on the ground, we call it a 'puddle'. Well, heat and work are equivalent to 'rain' -water in transit between being a cloud and being a puddle!
In physics, heat is the transfer of thermal energy between objects due to a temperature difference. It flows from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. Heat is a form of energy and is a key factor in understanding thermodynamics and the behavior of matter.
