Why it’s time to rethink your hot water system
Most of us don’t give much thought to our hot water systems. You turn the tap on, and it gives you hot water. Job done, right?
The truth is, sticking with an outdated hot water setup could be using more power than it needs to. And costing you more than it should.
More and more homeowners throughout Victoria and Australia are switching to heat pump hot water systems, and there are some good reasons for it. But before we dive into the benefits, let’s have a look at how they work.
What is a heat pump hot water system?
While electric systems convert electrical energy directly into heat, and gas systems burn fuel to raise the temperature, heat pump systems bring the temperature of the water up by extracting heat from the air around them. They use electricity to power a small compressor and fan, which circulate a refrigerant through a coil. This coil absorbs ambient heat from the air – even when it’s cold – and transfers it into the water storage tank.
It’s basically a fridge working in reverse. While your fridge pulls heat out from the inside to keep things cold, a heat pump pulls heat in from the outside to make your water hot.
So why do we recommend them? Here are some of the benefits.
1. Next-level performance
With their method of absorbing heat from the air and transferring it into your water, heat pump hot water systems are far more efficient than other systems that generate heat directly.
They have a Coefficient of Performance (COP) of 3 to 4, meaning that for every 1 kilowatt (kW) of electricity they use, they produce 3 to 4 kW of heat energy. Using up to 75% less electricity than conventional electric hot water systems, heat pumps are the most efficient systems on the market.
Many are tested to run reliably in temps as low as -10°C, so they handle Geelong’s winters easily.
And if you’ve got solar panels, you can schedule your heat pump to run during peak sunlight hours – boosting efficiency and slashing bills even further.
2. Lower power bills
Because they use far less electricity, heat pump hot water systems can deliver serious savings on your power bills. Switching from an electric storage system to a heat pump can save you up to 70% on your bills, depending on the model and usage.
That’s a significant cost cut. In real terms, many Victorian households report saving hundreds of dollars per year after switching – especially when the system is paired with solar panels or timed to run during off-peak hours.
While the upfront cost of installation might deter some (get a quote from Too Hot To Handle), they’re a long-term win for your wallet, and the savings start showing up from your very next bill.
3. Massive government rebates (if you act now)
If the installation cost is putting you off, this is the section for you. Right now, Victorian households are eligible for generous rebates to switch to energy-efficient hot water systems.
Under the Victorian Energy Upgrades (VEU) program, Federal STC Incentives, and the Solar Victoria Rebate, you can save hundreds or even thousands on the cost of supply and installation. It’s an upfront discount that makes the decision way easier.
4. Better for the planet
Thanks to their energy efficiency, heat pump hot water systems help cut down carbon emissions too. By replacing older electric or gas systems, a typical Victorian household will produce far lower CO₂ emissions.
That’s a huge environmental win, and it doesn’t come at the cost of comfort or performance. You still get reliable hot water, just with a much smaller footprint.
5. Low maintenance, long lifespan
Heat pump hot water systems are built with fewer moving parts than gas systems, which means less can go wrong over time.
Unlike conventional systems that continuously heat water, heat pumps only operate when needed, with modern ones using smart sensors and timers to maintain temperature efficiently. This reduces wear and tear on the components and cuts the risk of unexpected breakdowns.
Many models are also designed for easy servicing, with accessible parts and straightforward maintenance schedules. That means lower ongoing costs and fewer ‘no hot water’ emergencies.
6. Smarter control and convenience
Modern heat pump hot water systems come with smart features like programmable timers and WiFi compatibility. That means you can schedule your hot water to heat when electricity is cheapest — handy if you’ve got time-of-use tariffs or solar panels.
Some models even let you monitor and control usage from your smartphone, so you’re not just saving energy, you’re managing it more efficiently day to day. Check out Reclaim’s Wi-Fi controller to see how it works.
