When a heat pump hot water system is not working properly, it can quickly disrupt your daily routine. Inconsistent water temperatures or a complete loss of hot water is frustrating at any time, and even more so during Melbourne’s cooler months when hot water is essential.
It is best not to ignore early warning signs such as reduced hot water capacity or a noticeable increase in electricity bills. Because heat pump hot water systems are designed to be highly efficient, higher running costs often indicate a fault. Timely repairs can help prevent further damage, lower energy use, and extend the life of your heat pump hot water system.

Common signs that your Heat Pump Hot Water System needs repairing
It is generally recommended that you get your heat pump hot water system serviced every 12 months. Although they are very reliable it doesn’t mean that things can’t go wrong in between these services. In particular, heat pumps have more complex components, like compressors, fans, and electronic controls, which need regular checks to maintain efficiency and prevent faults.
Here are a few of the main signs that your heat pump hot water system is not working as good as it could be:
- Reduced hot water supply or water not reaching desired temperature
- Longer than usual time for water to heat up
- Unusual noises from the system, such as rattling, buzzing, or humming
- Displaying error codes or warning lights on the control panel
- Higher than normal electricity bills, indicating inefficiency
- Leaks or visible water around the base of the unit
- Frost buildup on the heat pump unit (for outdoor components)
- Water temperature fluctuates inconsistently during use
- The system fails to turn on at all or cycles on and off irregularly
- Strange smells or signs of corrosion, indicating internal damage

How a Heat Pump Hot Water Systems Work
Heat pump hot water systems use electricity to move heat from the surrounding air to warm the water in your storage tank. Unlike traditional electric or gas systems that generate heat directly, heat pumps rely on extracting heat from the air through a compressor and refrigerant cycle, working in a similar way to an air conditioner running in reverse. This method allows heat pumps to heat water more efficiently, often using significantly less energy than conventional systems.
Air from the surrounding environment is drawn over the evaporator coil, where the heat is absorbed and transferred to the water stored in the tank. A fan helps move air across the coil efficiently, and built-in sensors continuously monitor the water temperature to ensure it reaches the set level. Some systems also include additional features, such as timers or smart controls, to further optimise energy use.
Once the water reaches the desired temperature, the system automatically switches off to save energy. It will restart when more hot water is needed or when the temperature in the tank drops, maintaining a consistent supply for your household. This cycle ensures that your home has hot water available when you need it while keeping running costs as low as possible.
