Installing a heat pump is one of the smartest upgrades for reducing energy bills in Perth homes. However, getting the installation wrong can lead to poor performance, noise issues, or unnecessary costs. Before you commit, it’s essential to carry out a proper site audit to ensure your home is suitable.
1. Allow Enough Space for Airflow
Heat pumps rely on ambient air to operate efficiently, so airflow is critical. Most systems require at least 2–3 metres of clear space around the unit to function properly.
Installing the unit in a tight corner or enclosed area can restrict airflow, reducing efficiency and increasing running costs.
2. Consider Noise Levels
While modern heat pumps are relatively quiet, they still produce sound during operation. Noise levels are measured in decibels (dB), and placement matters — especially in suburban Perth homes.
- Avoid installing near bedroom windows
- Be mindful of neighbouring properties
- Check manufacturer noise ratings before purchase
Choosing the right location can prevent complaints and ensure long-term comfort.
3. Plan for Proper Drainage
Heat pumps produce condensate as part of the heating process. This water needs to be safely drained away from the unit.
Without proper drainage management, you may encounter pooling water, slippery surfaces, or potential damage to surrounding areas. Your installer should ensure runoff is directed to an appropriate drainage point.
4. Check Your Electrical Capacity
Heat pumps require a dedicated electrical connection, and older homes may need a switchboard upgrade to support the system.
Before installation, confirm:
- Your switchboard has sufficient capacity
- Safety switches (RCDs) are installed
- The system meets Australian electrical standards

5. Conduct a Proper Site Audit
A professional installation guide and site audit ensures your system is positioned for maximum efficiency and longevity. This includes assessing airflow, noise impact, drainage, and electrical setup.
If you’re planning an upgrade, our heat pump installation in Perth service includes a full site assessment to ensure everything is set up correctly from day one.
Set Your Installation Up for Success
Taking the time to check these factors before installation can save you from costly mistakes and performance issues down the track. A well-installed heat pump will deliver reliable hot water, lower running costs, and long-term efficiency.
