Why COP and EER Matter in Choosing the Right Hot Water Heat Pump

 Looking to switch to a hot water heat pump? One of the most important things you need to consider is energy efficiency. Not only does it influence how much you’ll save on your electricity bills, but it also determines your eligibility for government rebates.

At Climate Green Melbourne, we’re committed to helping you make informed, cost-effective choices. That’s why we’re breaking down the two most important energy efficiency metrics: COP (Coefficient of Performance) and EER (Energy Efficiency Ratio).

🔎 What Are COP and EER?

🔹 COP (Coefficient of Performance)

COP measures how efficiently your heat pump converts electricity into heat. For instance, a COP of 4 means that the system delivers 4 kilowatts of heat for every 1 kilowatt of electricity it consumes.

Simply put: the higher the COP, the better the efficiency and the lower the running cost. For hot water systems, this is the number you’ll want to pay close attention to.

🔹 EER (Energy Efficiency Ratio)

EER is mainly used to assess cooling efficiency. It calculates how much cooling a system provides per unit of energy used. While some heat pump models include this rating, it’s more relevant for air conditioners than hot water systems.

🔄 COP vs EER – What’s the Difference?

When selecting a heat pump for water heating, COP should always take priority.

💡 Why These Ratings Matter

Understanding COP and EER isn’t just about the numbers—it’s about:

  • Cutting down your electricity bills

  • Ensuring faster, more reliable performance

  • Qualifying for rebates and incentives

  • Reducing your environmental impact

A high COP means your system uses less power to heat more water—making it a win-win for your wallet and the planet.

🏆 Heat Pump Brands We Recommend

At Climate Green, we only work with high-performance systems that are rebate-approved and built to handle Victoria’s weather. Here are three of our most trusted brands:

✅ Emerald 300L Heat Pump

  • COP of approximately 4.5

  • Whisper-quiet operation

  • Excellent for cold climates

  • Fully compliant with STC requirements

✅ Neo Power Heat Pump

  • Consistent heating performance

  • Ideal for both homes and businesses

  • Compatible with Victorian rebate programs

✅ Ecogenica Heat Pump

  • Specifically designed for VEU compliance

  • Low-maintenance and energy-efficient

  • A reliable choice for eco-conscious households

⚠️ Real-World Factors That Affect Performance

Even a top-rated system needs the right conditions to operate efficiently. Key factors include:

  • Outdoor temperature – Colder weather can lower COP

  • Installation quality – Poor setup can reduce efficiency

  • System size – A unit too small or large won’t perform optimally

  • Maintenance – Blocked filters or aging parts can reduce output

That’s why we offer free site inspections to recommend the right system and ensure expert installation every time.



💸 Rebate Eligibility Based on COP

Programs like the Small-scale Technology Certificates (STCs) and Victorian Energy Efficiency Certificates (VEECs) are directly linked to your system’s COP.

To qualify for these financial incentives, your heat pump must typically have a COP of 3.5 or higher. With Climate Green, you can be confident your system meets all the necessary criteria—maximising your rebate potential.

🔮 Smarter, Greener Technology Ahead

Newer heat pump models continue to raise the bar with:

  • COP ratings above 5.0

  • Eco-friendly refrigerants like R290

  • Smart controls and AI optimisation

  • Seamless integration with solar power systems

At Climate Green, we bring the latest innovations straight to your home—so you stay ahead on energy efficiency and savings.
