How do heat pumps heat?

They pump the cold air out leaving only the warm air.

Heat is the measure of internal energy that an object has.  Heat flows from a hotter object to a colder object only.  The internal energy flows from the higher level to the lower level.  This is similar to flowing water.  The water in a lake at the top of the hill has more potential energy than the water in the lake at the bottom of the hill.  The water will flow downhill only.  The water flows from the location where it has a higher energy level to the location where it can have a lower energy level.

Thermal energy IS heat.

No. In both, you have a blower, much of the power (volts x amps x power factor) for that is pushing air around, some of that power is lost in heat.\n\nIn a heater (furnace) most of the power goes to heating elements. The remainder goes to the blower motor.\n\nIn an air conditioner, you have the same blower that you have in the heater, you also have the compressor (using power). Like the blower, much of the compressor power is doing work (squashing a gas back to a fluid [once it move through the condenser]). The remainder is lost in heat. The condenser unit (outside of your house) has boat loads of heat radiating from it. This is partially the heat being removed from your house (the main function of the air conditioner).

Heat transfer can occur through convection (ex: In the winter, the wind makes you colder), conduction (ex: heating a pot of water on an electric stove), and radiation (ex: sunlight warming the earth).

the principle is by compressing a coolant, and injecting this coolant into a small pipe, the size will minimize heat built up, as the coolant moves around the pipe or coil, air is blow into this coil which result into cooler air.\n\nThe coolant is then compress back to repeat the process.

I don't really understand what your question is.  In the first place, heat always flows from a warmer object to a cooler one.  That maximizes the number of possible arrangements of energy quanta, leading to an increased entropy.

There are several heat generating processes in a common television:\n\n1) Power transformer will generate heat\n2) Horizontal "flyback" transformer will generate heat\n3) Certain power transistors (notably, the Horizontal sync driver)\n4) The CRT generates some heat\n5) Any tubes (older TVs)\n\nMitigations:\n1) Air flow in cabinent\n2) Sufficient heat sinks on active devices\n3) Increase efficiency of transformers so less heat is produced\n4) Replace CRT with LCD ;-)

Do a search on "absorption cycle" refrigeration.\n\nThey work using heat alone and they have no moving parts. Quiet, reliable, and no electric pump is required. The refrigeration effect is obtained by exploiting a temperature-dependent solution concentration of two materials.\n\nThese are commonly used in mobile homes and in areas where an electric supply is not reliable.(or not available.)

They Are Called Pump Jacks \nSome Call Them Pumping Units

sure- it's easy- the refrigeration system moves heat out of one area into another- and simple experiment for you to do, is take a can of pressurized spray whatever, and spray it- can gets cold from reduction in pressure, allowing molecules space to "slow down" because they quit "bumping" from being in a tight spot- making room for more heat- or "making" cold- with me so far? now just picture a system with a pump that packs the gas molecules tightly together, and on the other end has a spot for them to expand (making room for more heat)and then runs the "heated" expanded gas through a radiator (heat comes out) and then gets compressed (packed) again- round and round "absorbs heat- moves heat- loses heat" \n hope this helps- if you really need more help email me through answers and I can provide pictures of how it works.

heat mainly - the energy is wasted in the form of heat instead of transferable energy

because a car turns heat energy into mechanical energy

Heat is the kinetic energy of molecules; the faster the molecules move, the more heat.\n\nConvection heat transfer is where faster-moving molecules bump into slower-moving ones, transferring their energy so the slower ones speed up and the faster ones slow down, until they reach equilibrium.\n\nRadiation heat transfer is where electromagnetic radiation, such as infrared light or microwaves, excite the molecules in a substance, causing them to speed up and thus heat up.\n\nBecause convection heat transfer only works when molecules make physical contact, convection won't work across a vacuum.  That's how a Thermos works.\n\nRadiation can cross a vacuum, which is how we get heat from the sun.  Hot objects give off infrared radiation, which can be reflected back and contained; that's how aluminum wrap works.

Convection. EXAMPLES: If you think about a pot of water that is heated on a stove, the stove burner heats the bottom of the pot by conduction. Water touching the bottom of the pot is also heated by conduction. As this water is heated, it expands and becomes less dense than the cooler, denser water that is above it. The cooler, denser water at the top of the pot sinks and pushes the hot, less dense water upward. As the hot, less dense water rises, its particles come in contact with colder water particles, so it gives up heat energy to the lower temperature water particles with which it collides. That is, it cools by conduction. As it cools it "contracts" and becomes denser, causing it to drop toward the bottom of the pot again, forcing the warmer water below it to rise. This movement causes convection currents. These currents transfer thermal energy from warmer to cooler parts of the liquid.

Heat also works very well.
