A heat pump water heater is an energy-efficient way to enjoy hot water throughout the year. It works by transferring heat from the surrounding air to the water, consuming much less electricity compared to conventional water heaters. However, to ensure it performs efficiently and lasts for years, a little care and regular maintenance go a long way. Here are some easy and practical tips to keep your heat pump water heater running smoothly.
1. Keep the surrounding area clean
Your heat pump needs good airflow to operate efficiently. Make sure the space around it is clear of dust, debris, or stored items. Regularly clean the air filters and vents to prevent blockages. This simple step helps your unit maintain better heat exchange, improving its performance and saving energy over time.
2. Check temperature settings
Setting the right water temperature can make a big difference in both comfort and efficiency. Most heat pump water heaters perform best when set around 55°C, while some models can go up to 75°C for higher requirements. Keeping it at an optimal level ensures faster heating and reduced electricity consumption. Adjusting the temperature also helps reduce scale buildup inside the tank.
3. Inspect for leaks and corrosion
Even a small leak can affect efficiency and increase water wastage. Periodically, check all connections, valves, and the storage tank for signs of corrosion or moisture. If you notice any water dripping or rust forming, contact a professional technician immediately. Preventive action at an early stage can avoid costly repairs later.
4. Flush the tank regularly
Over time, minerals and sediment can accumulate inside the tank, reducing its heating efficiency. Flushing the tank every six months helps remove buildup and extend the lifespan of your water heater. If your area has hard water, this step becomes even more important to prevent scaling on heating elements.
5. Use smart or energy-saving modes
Many modern heat pump water heaters, like A.O. Smith’s HPI 40, come with an Adaptive Energy-Saving (AES) system that automatically adjusts heating cycles to minimise energy loss. Using these intelligent modes ensures optimal water temperature while reducing power consumption. It’s a smart way to get consistent performance with lower running costs.
6. Schedule professional servicing
Even with regular self-maintenance, it’s wise to have your heat pump inspected by an authorised technician once a year. Professionals can check the refrigerant levels, electrical connections, and system components to ensure everything works efficiently. Regular servicing helps detect minor issues early and keeps your water heater performing like new.
7. Upgrade when needed
If your current water heater is not heating efficiently despite all efforts, consider switching to a more advanced model. For instance, AO Smith’s Xpress Series offers 33% faster heating compared to ordinary 3KW water heaters and comes with long-lasting glass-coated Incoloy heating elements. With smart modes and a BEE 5-star rating, it ensures both speed and efficiency.
Conclusion
A little maintenance goes a long way in ensuring your heat pump water heater performs at its best. By keeping it clean, checking temperature settings, and using energy-saving features wisely, you can enjoy reliable hot water and lower electricity bills for years.
