A HP is thermodynamic cycle which is designed to use both heating and cooling functions. A thermodynamic HP cycle transfers heat from one reservoir (air) to another reservoir (water). There are four components of a HP which are evaporator, compressor,condenser, and expansion valve.
The evaporator is a device like heat exchanger situated in the first reservoir. This evaporator makes possible heat from first reservoir in order to be transferred to a cold low pressure refrigerant. This heated refrigerant flows into the compressor to increase its pressure, causing an increase of the temperature. The refrigerant loses its heat and pressure to the second reservoir across the condenser before the refrigerant is returned to its initial low temperature

2.1.3. Disadvantages It extracts unsafe fume It is not easy to control outlet water temperature
2.2 Solar water heating systems
Solar panels are systems that generated heat or electricity by using the energy to be carried ray of the sun. Solar energy panels absorbs the sun’s energy with the aid of dark surfaces located inside panels. After obtained heat, water is heated by transferring water by solar energy panel.
2.2.1 Types
SWHSs are splitted into two categories which are active and passive. Passive system is one of the oldest systems for utilization of solar energy. Mainly, it is used to be heated and cooled of the building. It uses density gradients (gravitational forces) to provide with natural cycle the transfer of water or heat transfer fluid while active system uses a mechanical system (circulating pump) for cycle of water or heat transfer fluid [24].
2.2.2. Advantages The sun is plentiful and never-ending energy source There is any environment hazard such as sulfur, carbon monoxide, radiation, and fume because of using renewable energy souce
