Heat Pumps

The heat pump uses a small amount of electricity to extract a lot of the latent heat energy from the surrounding air. So a heat pump is also using the energy from the sun but only indirectly and so it can work day and night, winter and summer. The efficiency of a heat pump is called the COP (Coefficient of Performance). A COP value of 4 means that the heat pump produces four times as much thermal energy as what it uses electrically – in other words a 75% saving on the water heating bill. Using a COP value of 4, a high efficiency 4.7kW heat pump takes about 3 hours to re-heat a 200L geyser from a cold start. This enables you to always have hot water at a fraction of the cost no matter when or how much water you use. Unlike the solar option, a heat pump also requires virtually no change to your lifestyle and routine as it is not limited by the availability of the sun for heating. The main advantage of a heat pump is the ability to re-heat a geyser a few times per day and that it can work day and night, rain or shine.
