How It Works
A simplified explanation of how a heat pump works
Hot water heat pumps have been around for over thirty years. However, recent advances in technology can now deliver reliable performances.
A heat pump works by absorbing heat from the outside air and transfers it to the tank, heating up the water. The main technology behind a heat pump is similar to the principles used in your refrigerator. However, instead of pumping heat out of a fridge to keep the contents cool, the unit pumps heat through the tank, thus heating the water. A small amount of electricity is used to pump a refrigerant around the heat pump, which generates heat into the system.
> That Heat Pump technology is more energy efficient than Solar?
> Since 2009, the Campbell Creek Energy Efficient Home Project* has compared the energy usage of three homes, each with different types of heaters.
> The latest testing, from January to December 2012, confirmed that the Solar Flat Panel system used 38% more energy than the Hot Water Heat Pump.
