Quantum Heat Pump Review: Does It Still Stack Up in 2025?

When it comes to energy-efficient hot water systems, the Quantum heat pump is a well-known name. But in a fast-changing market, is it still the best option for Aussie homes?

Let’s break down the pros, cons, and how it compares to newer models.

⚡ Energy Efficiency & Cost Savings

Quantum heat pumps are designed to slash your electricity bills — but are they keeping up?

Pros:

• Cuts running costs by up to 70%

• No booster required, even in colder climates

• Eligible for STCs and VIC rebates

• Quiet operation — just 48 dB(A)

💡 Verdict: Good efficiency, but competitors like Rheem Ambiheat offer smarter energy control and better COP.

🔧 Installation & Setup

Quantum heat pumps are made for simple installation without major home modifications.

Why it’s easy to install:

• No rooftop panels needed

• Small footprint fits most yards

• Tolerates harsh water conditions

💡 Verdict: Flexible setup, though some units may need plumbing adjustments.

🔒 Durability & Warranty

These systems are built for Aussie conditions, but their warranty is shorter than others.

Quantum heat pumps are an eco-conscious alternative to electric storage or gas systems.

Sustainability Features:

• Extracts renewable heat from the air
