Heat Pump Hot Water System Sydney

How do Heat Pump Water Heaters Work?

A heat pump hot water system operates by extracting warmth from the surrounding air and using it to heat water efficiently. Here’s a simplified breakdown of how it functions:

Air Absorption
The system begins by drawing in ambient air through a fan.

Heat Extraction
As the air passes over an evaporator coil, it transfers its heat to a refrigerant inside the coil. This refrigerant has a low boiling point and easily converts from liquid to gas when heated slightly.

Compression
The gaseous refrigerant is then compressed, which significantly raises its temperature.

Heat Transfer
The hot compressed gas passes through a heat exchanger within the water tank, transferring its heat to the water.

Refrigerant Recycle
After losing its heat, the refrigerant condenses back into a liquid and returns to the evaporator to repeat the

Electric Water Heater vs. Heat Pump.

Efficiency and Energy Use

Electric water heaters and heat pump water heaters both run on electricity, but they differ significantly in how they use it. Traditional electric water heaters use electric resistance coils to generate heat, which is then transferred to the water. This process is straightforward but relatively inefficient, leading to higher electricity consumption​.

Heat pump water heaters, on the other hand, use electricity to move heat rather than generate it. They extract heat from the surrounding air and transfer it to the water, similar to how a refrigerator works but in reverse. This method is much more efficient, using up to 60% less electricity compared to traditional electric water heaters​.

Cost and Savings

While heat pump water heaters have a higher initial cost, they offer significant savings over time. According to ENERGY STAR, households that switch from an electric water heater to a heat pump water heater can save from $270 to $550 annually, depending on the household size. This equates to $2,050 to $5,610 over the lifespan of the unit, often offsetting the initial cost of the heat pump hot water system​​ & its installation.

Electric water heaters are less expensive upfront but tend to incur higher operational costs due to their energy consumption. Therefore, while they might be more affordable initially, they are generally more expensive to operate in the long run​.
