Why Heat Pumps Outperform Gas & Electric Hot Water in Melbourne’s Cold Winters

Why Heat Pumps Outperform Gas & Electric Hot Water in Melbourne’s Cold Winters

Cold Mornings. Soaring Bills. There’s a Better Way to Heat Your Water.

If you’re waking up to freezing floors and steamy showers that cost a fortune, you’re not alone. Victorian winters can be brutal — not just for your comfort, but for your energy bills too.

Most households in Melbourne still rely on old gas or electric hot water systems that were never designed for modern efficiency — or for the sharp energy price hikes we’re seeing today.

But there’s a better alternative:
Heat Pump Hot Water Systems – designed for efficiency, built for cold climates, and ready to save you money year-round.

Heat Pump

How Do Heat Pumps Work in Cold Weather?

Imagine running your water heater like a smart refrigerator in reverse. Instead of burning gas or running electricity through coils, a heat pump pulls warmth from the air, compresses it, and transfers that energy into your hot water tank.

Even when it’s cold outside, modern heat pumps are equipped with cold-climate performance tech — capable of working in temperatures as low as -5°C, which is perfect for Melbourne’s frosty mornings.

✅ Bonus: They work even better when combined with solar — using your own energy to heat water nearly for free.

Gas vs Electric vs Heat Pump: Which Costs More in Winter?

Let’s break it down with a real-world example:

For a 4-person home in Melbourne:

Over the course of a year, switching to a heat pump could save you $700+, especially if you’re currently on an old electric hot water systems.

How Much Could You Save in Victoria?

Here’s what our average GreenOz customer sees after switching:

  • 65%–75% reduction in hot water energy usage

  • Cut carbon emissions by up to 3 tonnes per year

These aren’t just numbers — they’re freedom from high bills, more reliable hot water, and a cleaner footprint for your family.

Still Eligible for Rebates? Yes — Through STCs & VEU

Although the Solar Victoria battery rebate has ended, homeowners can still claim significant savings through:

  • STCs (Small-scale Technology Certificates): Federal rebates reducing upfront costs (usually $700–$1,200 off)
  • VEU (Victorian Energy Upgrades): State scheme offering extra savings when replacing older gas or old electric hot water systems

GreenOz handles all eligibility checks and paperwork — so you don’t miss a cent.

Why Now Is the Right Time to Upgrade

Victorian winters bring:

  • Peak electricity demand
  • Longer hot water usage cycles
  • Higher installation wait times (installers get booked quickly!)
  • Cold shocks that cause old systems to fail

If you wait until your gas or old electric hot water systems breaks down, you’ll be left paying more at the worst time. Acting now gives you time to install smart, not under pressure.

Key Takeaways

  • Heat pumps are the most efficient hot water systems for cold Victorian winters
  • They outperform gas and electric in cost, carbon, and reliability
  • Federal STCs and VEU rebates can cover a large portion of your upgrade
  • Winter is the smartest time to act — before bills climb or systems fail
