Switched to a Heat Pump Hot Water System in Melbourne: Here’s Why I Don’t Regret It

For years, my hot water came from a standard gas system. It worked fine… until the bills started creeping up. Every quarter, I’d brace myself for that envelope in the letterbox, and sure enough, the numbers kept climbing. It wasn’t just the money; it was also the nagging feeling that I could be doing better for the environment.

After a particularly steep gas bill last year, I started looking for alternatives. A friend mentioned heat pump hot water systems, but honestly, I had no idea how they worked. A quick search for heat pump hot water system Melbourne led me to Harley Plumbing, and that’s when I realised there might be a way to save money, reduce my carbon footprint, and still enjoy long, hot showers.

Why I Decided to Make the Switch

The first thing that caught my attention was efficiency. Heat pump hot water systems use a clever process that extracts heat from the air to warm water. It’s a bit like an air conditioner in reverse. This means they use a fraction of the electricity that a traditional electric water heater would need, and unlike gas systems, there’s no constant burning of fuel.

When I spoke to Harley Plumbing, they explained that a heat pump hot water system can cut hot water energy use by up to 75%. In Melbourne, where gas prices have been climbing steadily, that’s no small saving. They also told me that switching from gas could reduce my hot water-related gas bill by up to 68%, which adds up to hundreds of dollars a year.

I’ll admit, I was also thinking about the environment. Harley Plumbing showed me figures suggesting that over ten years, a heat pump could cut my household’s carbon emissions in half compared to gas, about 4.1 tonnes of CO₂ instead of 8.5. That’s a big win for my family’s footprint.

The Rebate Game-Changer in Victoria

One of the biggest hesitations I had was the upfront cost. A quality energy-efficient hot water system like a heat pump can set you back between $3,000 and $5,500 before rebates. That’s not pocket change.

But this is where Harley Plumbing really impressed me; they knew the Victorian hot water rebates and incentives inside out. They explained I could get:

• Up to $1,000 from Solar Victoria (depending on eligibility)
  
• Small-scale Technology Certificates (STCs) worth hundreds, sometimes thousands
  
• Victorian Energy Efficiency Certificates (VEECs) for further savings
  

They didn’t just point me towards the rebates; they handled all the paperwork. My final out-of-pocket cost ended up being around $1,500, which made the decision a whole lot easier.

Installation Day with Harley Plumbing

I’ve had my share of tradie no-shows in the past, so I was prepared for delays. But the Harley Plumbing team arrived right on time, introduced themselves, and walked me through the process before touching a single tool.

They removed my old gas unit, set up the new heat pump, and had it running in just a few hours. They even tidied up afterwards,no random bits of pipe left in the driveway.

One thing I appreciated was how they explained the maintenance. Unlike gas systems, there’s no pilot light or combustion chamber to worry about. The main upkeep is checking the air filter and making sure the outdoor unit has plenty of airflow. Easy.

Living with a Heat Pump Hot Water System

The first thing I noticed was… nothing. My showers felt exactly the same, the water pressure didn’t change, and I wasn’t waiting any longer for hot water.

The real difference came when the next gas bill arrived; it was much lower. Since the heat pump runs on electricity and uses so little of it, I’d slashed my gas usage significantly.

I also like the peace of mind that comes with not relying so heavily on gas. With energy prices fluctuating, having a system that’s less tied to those hikes feels like a smart move.

What I Wish I Knew Beforehand

If I had to do it all over again, I’d have switched sooner. But there are a couple of things worth knowing:

• You need a bit of outdoor space. The unit needs good airflow to work efficiently, so it can’t be crammed into a tiny, enclosed spot.
  
• The upfront cost is higher. Even with rebates, it’s an investment, but it pays for itself in 3–5 years through savings.
  

Neither of these is a deal-breaker, but they’re worth considering before making the switch.

Why I Recommend Harley Plumbing for Heat Pump Installation in Melbourne

The product is one thing, but the experience of getting it installed is another. Harley Plumbing made the process easy from start to finish:

• They gave me a clear, honest quote with rebates already factored in.
  
• They didn’t try to oversell me on a system I didn’t need.

• The installation was quick, clean, and professional.
  

They’ve been in the Melbourne plumbing game for years, and it shows. They know the local regulations, the rebate system, and the practicalities of fitting a heat pump in different types of homes.

Final Verdict: Do I Regret It?

Not at all. If anything, I regret not doing it sooner. I’m saving money every quarter, I’ve reduced my household’s emissions, and I’ve got a reliable system that should last well over a decade.

If you’re in Melbourne and thinking about upgrading your hot water, I’d say give Harley Plumbing a call. Even if you’re just curious, they can run the numbers and let you know exactly what your savings and rebates could look like.
