A heat pump is one of the most efficient hot water systems you can install — but like any appliance, it needs regular care to perform at its best. With the right DIY maintenance and professional servicing, your system can easily reach a lifespan of 15 years or more.
Why Maintenance Matters
Heat pumps rely on airflow, pressure, and efficient heat exchange. Over time, dust build-up, worn components, or neglected servicing can reduce performance and increase running costs.
Simple maintenance steps can protect your investment and ensure consistent hot water year-round.
Clean the Air Filters and Intake
Your heat pump draws in ambient air to operate, which means the air intake can collect dust and debris. If left unchecked, this restricts airflow and reduces efficiency.
- Check and clean filters every 3–6 months
- Remove leaves or debris around the unit
- Ensure at least 2–3 metres of clear airflow space
This is one of the easiest ways to maintain system performance.
Check the PTR Valve Every 6 Months
The Pressure Temperature Relief (PTR) valve is a key safety component. It releases pressure if the system becomes too hot or over-pressurised.
Every six months, you should:
- Gently lift the valve lever to ensure water flows
- Check for leaks or irregular discharge
- Confirm the valve resets correctly after testing
If you notice any issues, contact a professional plumber immediately.
Book an Annual Professional Service
While basic checks can be done yourself, an annual service by a qualified technician is essential. Experienced Perth plumbers like
Sureflow and
Splash and Gas can inspect critical components and ensure everything is running safely and efficiently.
A professional service typically includes:
- System performance checks
- Electrical and safety inspections
- Refrigerant and component assessment

Know When to Act
Signs your heat pump may need attention include unusual noise, reduced hot water supply, or higher energy bills. Addressing these early can prevent costly repairs and extend the system’s lifespan.

Australian Government hot water system guide.
Protect Your Investment
A little care goes a long way. By combining simple DIY checks with professional servicing, you can maximise efficiency, avoid breakdowns, and ensure your heat pump delivers reliable performance for years to come.
