What to Expect When Upgrading from Gas to Heat Pump

Upgrading from Gas to a Heat Pump Hot Water System in Australia: What to Expect

Why Australians Are Making the Switch

Homeowners across Australia are rethinking how they heat their water. Rising gas prices, increasing environmental awareness, and generous government incentives are making heat pumps an attractive alternative. Whether you’re living in a bustling suburb of Melbourne or a quiet corner of Adelaide, upgrading from a gas system to a heat pump hot water system could dramatically improve your energy efficiency—and your wallet.

If you’re considering heat pumps in Victoria or exploring heat pumps in Adelaide, this comprehensive guide will show you exactly what to expect from the upgrade process, including costs, installation, operational differences, and government rebates.

What Are Heat Pump Hot Water Systems?

Heat pump water heaters work by extracting heat from the surrounding air and transferring it to water—similar to how a refrigerator operates, but in reverse. Instead of generating heat directly like gas or electric systems, heat pumps move heat using a refrigerant cycle, making them up to 70% more energy-efficient.

The Top Benefits of Upgrading

Lower Running Costs

  • Heat pumps can be up to 3–4x more efficient than electric or gas systems.
  • Average annual savings in Victoria: up to $685
  • In New South Wales: savings range from $606 to $1,213 per year

Better for the Environment

  • No combustion = Zero direct emissions
  • Reduced carbon footprint, especially when paired with solar
  • Helps Australia meet net-zero targets

Safety and Health

  • No risk of carbon monoxide poisoning or gas leaks
  • Better air quality with no indoor combustion
  • No open flames or pilot lights

Boost in Property Value

  • Energy-efficient homes are increasingly desirable
  • Government incentives add additional appeal for potential buyers

Heat Pump vs Gas Hot Water Systems: Feature Comparison

When deciding between a gas hot water system and a modern heat pump system, it’s helpful to understand how they compare across key performance areas:

  • Noise Levels
    • Gas System: Generally quiet, with occasional crackling sounds during heating
    • Heat Pump: Operates at 35–55 dB—comparable to a refrigerator or electric kettle
  • Heating Time
    • Gas System: Heats water quickly, often providing hot water on demand (especially in instantaneous systems)
    • Heat Pump: Slower recovery rate compared to gas, but many units include hybrid or booster elements for faster heating when needed
  • Climate Suitability
    • Gas System: Reliable performance in any temperature or weather condition
    • Heat Pump: Traditionally less efficient in colder weather, but modern heat pumps in Victoria and Adelaide are now specifically engineered to perform efficiently in both cold and hot climates—making them suitable all year round

Available Rebates and Incentives (By State)

Federal STC Scheme

  • Applies nationwide
  • Value depends on model, location, and current market price (~$36/STC)

Victoria

  • Solar Victoria Rebate: $1,000
  • VEEC (gas-to-heat pump): ~$500
  • Combined savings: Up to $1,500+
  • In some cases, business upgrades may qualify for a free heat pump

South Australia

  • REPS: Up to $847 + $113 for priority groups

Choosing the Right Heat Pump System

Key Considerations

  • Household Size: 50L per person/day rule
  • Climate: Cold-climate models may be required
  • Space: Outdoor ventilation is essential
  • Budget: Consider upfront vs long-term savings
  • Efficiency: Look for higher COP/SCOP ratings

  • Especially effective when powered by solar energy

Myths About Heat Pumps – Debunked

Despite their growing popularity, heat pumps are still surrounded by outdated misconceptions. Let’s clear the air.

❌ Myth 1: “Heat pumps don’t work in cold climates.”

✅ Truth: While older models struggled, today’s systems—especially in Victoria and South Australia—are designed for ambient temperatures as low as -10°C. Many include defrost cycles, boost modes, and cold-weather engineering.

❌ Myth 2: “They’re way too noisy.”

✅ Truth: Modern heat pumps operate between 35–55 decibels—equivalent to a quiet conversation or fridge hum. Many split systems isolate the noise-producing components away from living areas.

❌ Myth 3: “Gas is cheaper in the long run.”

✅ Truth: With gas prices on the rise and government rebates pushing down install costs, heat pumps now offer better long-term value. Add in solar compatibility and you’re looking at up to 70% lower hot water energy use.

❌ Myth 4: “They’re hard to install.”

✅ Truth: For experienced professionals, installation is straightforward. Most reputable installers will coordinate both the plumbing and electrical work, and even help claim your rebates.

❌ Myth 5: “You need a huge property.”

✅ Truth: Many integrated systems have a compact footprint. Even split systems can be designed for tight spaces with clever compressor placement.

The Future of Home Energy in Australia

As the country shifts toward net-zero emissions, the role of household energy choices is more important than ever. Gas bans in new builds are already underway in parts of Victoria, and other states are likely to follow.

Trends Driving the Heat Pump Boom

  • Rising gas prices: Experts predict continued volatility, especially with global energy instability
  • Home electrification: More homes are ditching gas altogether in favour of all-electric appliances
  • Solar uptake: Over 3 million Aussie homes have rooftop solar—pairing solar with a heat pump maximizes self-consumption
  • Smart grid integration: Many heat pump models are now compatible with demand response technology, enabling homeowners to shift usage to cheaper, greener times of day
