If any of the above interests you then how you heat your home or building is critical.
The heat pump, as an alternative energy source, offers a smart solution for heating buildings and water.

Air, earth and water - the three most important elements of our life.

In future, their significance will be even greater. They are, and very few of us know, immense sources of free renewable thermal energy. Solar radiation from the sun heats the air, earth and water. The technology required to extract heat captured in the air, earth and water has been known for more than a hundred years. That technology is called a heat pump.

A heat pump, using electricity, is capable removing from either the air, earth or water this otherwise non-usable heat and converting it into heat suitable for heating our homes and other applications.

How does a heat pump work?

A heat pump works just like your domestic fridge. The main components in both a fridge and heat pump are very similar - an evaporator, a compressor, a condenser and an expansion valve. The component that makes the whole process possible is a gas we call the refrigerant. The refrigerant boils at incredibly low temperatures typically -35OC. When you place an item e.g. a can of beer, in your fridge to cool, the cycles begins with the refrigerant boiling and evaporating as it is passes through the evaporator otherwise known as the metal part that makes the ice cubes. The heat required to evaporate the refrigerant comes from the can of beer and the other contents of the fridge. A heat pump works exactly the same way except this time the heat required to evaporate the refrigerant comes from the air, earth or water.

Heat pump efficiencies

The ratio of heating output to electric power input is called coefficient of performance or COP. A typical seasonal COP value is 4. This figure means the heat pump will use 1kW of electrical energy to produce 4 kWh of thermal energy. Other heating appliances e.g. gas and oil boilers fail to achieve a COP of even 1. So when compared to a COP of 4 you can imagine the energy savings a heat pump offers when compared to more traditional heating systems.
