Answers to the most common heat pump installation questions.

What rebates and incentives are available in Victoria?

You can reduce upfront costs through two main programs:

Federal STCs (Small-scale Technology Certificates): Every heat pump qualifies. Your installer applies the value as a direct discount. Typically $600-$1,200, depending on your location and system size. STC prices fluctuate, so exact amounts vary.

Victorian Energy Upgrades (VEU): If you’re replacing gas or old electric heating, you may qualify for additional savings. Value varies based on your current system.

Typical total savings: $1,100-$2,200+

Note: The Solar Homes Program ended June 30, 2024. Any $1,000-$1,400 rebates you’ve seen are no longer available.

We recommend getting a quote so we can confirm what applies to your home and provide exact figures based on current market rates.

Heat pumps extract thermal energy from the air and transfer it to heat your water. They don’t generate heat, they move it.

The process:

  1. An outdoor coil absorbs heat from air (even in cold weather)
  2. A compressor concentrates this heat
  3. The hot refrigerant transfers heat to your water tank
  4. The cycle repeats


Key advantage:
For every unit of electricity used, a heat pump delivers 2.5-4 units of heat. This makes them far more efficient than electric resistive heaters or gas systems.

Most Victorian homes use air-source heat pumps because they’re cost-effective and reliable. Ground-source options exist but are expensive and rarely used in homes.

Yes. Heat pumps work reliably across all of Victoria, from Melbourne to regional areas and even the mountains.

Performance varies seasonally:

  • Winter efficiency drops in very cold weather (below 5°C) because there’s less thermal energy to extract
  • Summer performance is excellent
  • Australian winters are mild, so backup heating rarely activates

By region:

  • Melbourne metro: Excellent year-round performance
  • Regional Victoria (Bendigo, Ballarat): Good performance, winter efficiency slightly lower
  • Mountain regions: Still effective, may see lower winter efficiency

Heat pumps work well in Victoria. Your actual savings and performance depend on your location, current system and water usage, not whether they “work” here.

Price ranges (unit + installation):

  • Basic system: $3,500-$6,000
  • Mid-range system: $5,500-$8,500 (most common)
  • Premium system: $8,000-$12,000+

What affects price:

  • System capacity (home size)
  • Brand and efficiency rating
  • Installation complexity
  • Additional work (new pipework, electrical upgrades)

After rebates and incentives: Your out-of-pocket cost is typically $1,700-$4,500 after federal and state support.

Most households recoup the cost within 5-8 years through energy savings. After that, it’s essentially free hot water (minus electricity).

Accurate pricing requires a site assessment. We’ll provide a real quote based on your home, not rough estimates.

Typical annual savings:

  • From gas heating: $300-$600/year
  • From old electric heating: $600-$1,200/year
  • From newer electric systems: $200-$400/year

What affects savings:

  • Your current heating system (worse system = bigger savings)
  • Hot water usage (larger families save more)
  • Electricity rates (change over time)
  • Your location (Melbourne performs better than cold regions)

Real example: A Melbourne family with gas heating using 60L/day might save ~$400 in Year 1, ~$2,000 over 5 years.

With upfront rebates, your net cost could be close to zero or paid back within 5 years.

Beyond cost, heat pumps offer lower environmental impact, quiet operation, and reliability.

We can provide accurate savings estimates based on your current bills and usage.
