What is a Heat Pump

Being an energy efficient person is to prove how well you manage in choosing products and services that can have lower power consumption resulting in a healthier home and environment. With rising prices in all dimensions be it grocery or gasoline, it is truly a challenge in managing a household budget. There comes in energy efficiency wherein every household can take necessary steps in conserving energy in all possible opportunity. One such energy efficient product is a heat pump. For those who are wondering what is this heat pump all about and how does it help in energy saving, you would for sure be surprised to know that this system can be used for heating and cooling needs of your house round the year on a daily basis.

A heat pump is a device or a machine that extracts heat from one place at a lower temperature to another at a higher temperature. They draw heat out of the air or ground and use same to heat a house or an office building and the best part is that it is fully reversible which means that a heat pump can also be used in cooling the house or building. Thus the biggest advantage is that there is no necessity to install two separate systems for heating and cooling needs. Another amazing fact about a heat pump is about its efficiency in energy, wherein the heat is simply transferred without the requirement of burning fuel to create heat.

A heat pump is also a creative way of heating water without solar panels which uses one third of energy of an electric water heater thereby resulting in saving a big chunk of power bills.

So how does this whole process of this heat pump work? The basic process used by a heat pump goes like this.

  • Firstly the external air or heat is drawn inside the system of heat pump through a fan into an evaporator which contains a fluid or refrigerant that is well stored in the piping.
  • This refrigerant has a boiling point of 26C and for your information water has a boiling point of 100C. Therefore the air which is drawn from outside is comparatively warmer than the refrigerant stored thereby converting the fluid into gas, all inside the piping of the heat pump.
  • Then a compressor after compressing the gaseous refrigerant sends the same out through a small valve thereby generating good amount of heat.
  • From there the heat is transferred from the gas pipe to a water tank. Once the heat is drawn the refrigerant comes back to its liquid state and the whole cycle could be started again.

One must understand the fact that heat pump works on moderate conditions and not on extreme conditions. Thus speak to an experienced contractor dealing in heat pumps and discuss the requirements and limitations and take a wise decision.
