A heat pump is a device that uses a small amount of energy to move heat from one location to another. Air source heat pump operates on the basic principle of heat transfer. Heat transfer means That rather than burning fuel to create heat, the device moves heat from one place to another.
Heat pumps are usually used to pull heat out of the air to heat a home or office building, or they Can be switched into reverse to cool a building. Heat pump mainly consists of a compressor, fan (applicable to air to water) evaporator and Condenser housed in a single unit. If you know how an air conditioner works, you already know a lot of heat pump as both heat Pumps and air conditioners operate in similar way.
The innovative Heat Pump Technology works on Refrigerant Reversed Carnot Cycling; Absorbing heat from the atmosphere (free from sun).

Heat pump is a promising technology that uses the same mechanical principles as refrigerators and air conditioners to generate hot water. Unlike conventional electricity and fossil-fuel-fired water heaters, heat pump takes heat from the surrounding air/water/soil and transfer it to the water in the tank.
The heat pump works by taking heat from the surrounding air/water/soil and using it to heat low pressure liquid refrigerant in the heat pump’s evaporator, vaporizing the liquid. The refrigerant then passes through the Compressor, which raises the refrigerant pressure and thus the temperature as well. The heated refrigerant gas passes through the heat pump condenser, where it gives off its heat to the water and condenses back into the liquid state. The liquid refrigerant now passed through an expansion valve or capillary where the pressure is reduced and the cycle starts over. Heat pumps mainly consist of a compressor, fan (applicable to air to water), evaporator and condenser. The compressor requires electricity to compress the refrigerant and vaporize it, and the fan requires a small amount of electricity to continually blow air across the evaporator coils when the unit is operating. The only electricity cost is the operation of the compressor and the fan in order to collect the free heat and pump it to the hot-water.
Analysis On Energy – Saving Principle.
Heat pump is driven by electrical power, but the electrical power is used to drive the heat pump system to absorb heat energy from environment and release the heat into water, so it different from electrical water heater which directly uses one kilowatt-hour to create 86Okcal energy to heat water.
Through experiment, we know that the energy absorbed from environment by one kilo-watt hour in heat pump system is three times as 860 kcal, so the cost for heat pump is one third of electrical water heater. Giving a metaphor, heat pump can use one kilo-waft hour energy to absorb 2-4 kilo-watt hour free energy, and then transfer all the energy into water. Finally, the COP can reach 3-5.
Generally speaking, we directly use some energy to heat water. Efficiency of electrical water heater is about 95%. while that of natural gas is about 80%. Heat pump water heater use electrical energy to drive compressor not directly to heat water, and the heat energy comes from low grade heat source. Saving energy is saving money. Compared with electrical boiler, oil boiler and gas boiler, heat pump can save two thirds of the running cost. Compared with coal boiler, heat pump which is environmental protection can save one third of running cost.
Complete isolation between water and electricity. No potential electric shock problem. No fuel tubes and storage, no potential danger from oil leakage, fire, explosion etc.
Adopts heat pump principle, which absorbs heat from outdoor air and produces hot water, thermal efficiency can up to 450%.

If you use your heat pump on a regular basis, you should change the filter about once a month. You could probably get away with only changing the filter once every three months if you only run the unit periodically. Keep fans and coils clean and free from debris, and have your heat pump inspected by a professional once every year or two.
Common problems with heat pumps include low airflow, leaky or noisy ducts, temperature problems, using the wrong refrigerant charge, rattles, squeaks and grinding noises. If you can, try to isolate the location of the problem. Is the airflow only low coming out of one register, or do all registers have low airflow? Is the offending noise coming from the air ducts or within the heat pump unit itself
There are a few things you can do to identify and possibly fix a heat pump problem before calling for professional help. First, if the unit isn't working, try resetting its motor. Check the pump ignition system for problems, and make sure you don't have a tripped circuit breaker or blown fuse. Check the thermostat to make sure it's working properly. Change the filter if it's dirty, and make sure there are no airflow blockages. If the air ducts are making noise when they expand and contract, you could try putting a dent in the side of the duct to make the surface more rigid. Rattles may be fixed by fastening loose parts, and if you're hearing squeaks inside the unit, you may need to replace or adjust the fan belt connecting the motor and the fan. A grinding noise may indicate that the bearings on the motor are worn out, which will require the help of a professional to fix.
Keep in mind that if you aren't mechanically inclined then you probably shouldn't attempt to do this kind of repair work. And because heat pumps can contain hazardous materials, that's another good reason to get some professional assistance. A chemical leak is bad news and you can easily injure yourself handling a broken device.
A heat pump should last between 10 and 30 years, with geothermal units leading the way in longevity. In fact, some components of ground-source heat pumps can last even longer. Keep in mind that technology may change before your heat pump has worn out, so you may find your heat pump outlasts a technician's ability to service it. New technologies may make heat pumps safer or more efficient, so you may wish to keep an eye out for new kinds of heat pumps.
