Heat Pump Hot Water Systems Sydney
A heat pump is the cheapest hot water system to run in most Sydney homes, and if you are still on an old electric storage tank, it is usually the single biggest cut you can make to your power bill. Sydney’s mild climate suits the technology almost perfectly, and rebates can take a decent chunk off the upfront cost.
We install gas, electric, solar and heat pump systems, so we have no reason to push you toward one. We will assess your household, tell you honestly whether a heat pump suits your place, sort the rebate paperwork, and install it so it runs quietly and efficiently.

What We Do
Heat Pump Hot Water Installation, Repairs and Servicing
Whether you are replacing a failed tank today or planning an upgrade, we cover the whole job from assessment to handover.
Heat Pump Hot Water Installation
Full supply and install, including removing and disposing of your old system, positioning the new unit for airflow and noise, connecting the water and condensate drainage, fitting the tempering valve, and commissioning and testing the system before we leave.
Switching From Electric or Gas
Most of our heat pump work is a changeover from an ageing electric storage tank, which is where the savings are largest. We handle the swap, arrange the electrical connection where a new circuit is needed, and set the timer so the system runs when power is cheapest or when your solar is producing.
Sizing and System Assessment
Undersizing is the most common cause of people being unhappy with a heat pump. We look at how many people are in the home, how many bathrooms run at peak, and your daily pattern, then recommend a tank size and model that will actually keep up.
Heat Pump Repairs
Not heating, running constantly, tripping the circuit, leaking, error codes on the display or unusually noisy. We diagnose the fault and tell you plainly whether it is a repair or whether the unit has reached the end of its life.
Servicing and Maintenance
Heat pumps need a little more attention than a plain electric tank. We clean the air filter and evaporator, check the refrigerant circuit and compressor operation, test the relief and tempering valves, and confirm the timer and boost settings are still doing what they should.
Rebate Assistance
We will walk you through which incentives currently apply to your situation and take care of the paperwork so the discount is applied properly rather than being something you chase later.
HEAT PUMP INSTALLERS
Your Local Heat Pump Hot Water Plumber in Sydney
There is something worth knowing about the heat pump market right now. A lot of the companies installing them do not do anything else. They exist because of the rebates; they only sell one product, and the answer to whether a heat pump suits your house is decided before anyone arrives. Some do good work. Plenty install units in whatever corner is closest to the old tank, undersize them to hit a price, and move on.
We install gas, electric, solar and heat pump systems. That means we have no reason to talk you into one. If your household would be better off on continuous flow gas, we will say so. If a heat pump is the right call, which for most homes replacing an old electric tank it is, we will size it properly and put it somewhere it will actually work.
A heat pump has a compressor and a fan, so it makes a sound similar to an outdoor air conditioning unit. On the tight blocks and side passages common through Killara, Lindfield, Roseville and Chatswood, the difference between a unit outside a bedroom window and one placed thoughtfully is the difference between a system you forget about and one that annoys you and your neighbour every night. It also needs clear airflow around it, so tucking it into an enclosed cupboard or a fenced-in corner will quietly wreck its efficiency.
Call 0461 330 531 for same-day service, or request a free assessment, and we will come back to you quickly.
Warning Signs
How Does a Heat Pump Hot Water System Work?
A heat pump does not create heat; it moves it. It is the same technology as your fridge or air conditioner, just running in the useful direction. That is the whole reason it is so cheap to run.
- It draws in ambient air - A fan pulls air across an evaporator containing refrigerant, which absorbs warmth from the air even on a cool Sydney morning.
- The refrigerant turns to gas - That absorbed warmth is enough to boil the refrigerant into a low-temperature gas.
- A compressor raises the temperature - Compressing the gas concentrates the heat and pushes it up to a temperature useful for hot water.
- The heat transfers to your tank - The hot gas passes through a heat exchanger wrapped around or inside the storage tank, heating the water.
- The cycle repeats - The refrigerant cools back to a liquid and starts again, storing a full tank of hot water ready for use.
Because the electricity is only running a fan and a compressor rather than a heating element, a heat pump typically delivers around three to four units of heat for every unit of electricity it uses. In practical terms, that is around 60 to 75 per cent less electricity than a conventional electric storage tank doing the same job.

Why Sydney Homeowners Choose R&G for Heat Pumps
We Install Every System Type, So Our Advice Is Neutral
Gas, electric, solar and heat pump. We are not a single product operation, so if a heat pump is not right for your household, we will tell you rather than sell you one anyway.
We Size It to Your Household
Almost every complaint about heat pumps traces back to a unit that was too small or set up badly. We work out your real peak demand before recommending anything.
We Think About Where It Goes
Airflow, clearances, condensate drainage, and how far it sits from bedroom windows and the neighbour's fence. Placement decides whether you love the system or resent it.
We Handle the Rebate Paperwork
We will explain what currently applies to your situation and process it properly, so the discount is real and applied at the time rather than promised and forgotten.
$0 Call-Out and a Fixed Price
No charge to come out and assess, a clear fixed price before any work starts, and workmanship backed by a guarantee.
OTHER SYSTEM TYPES
Heat Pump Hot Water Rebates in NSW
Federal Incentive (Small-scale Technology Certificates)
Heat pump hot water systems are classed as renewable technology under the federal small-scale scheme, which generates certificates when an eligible system is installed. In practice, the value is applied as a discount at the point of sale rather than something you claim back later. The amount varies with the model, its efficiency and the certificate market.
NSW Energy Savings Scheme and Peak Demand Reduction Scheme
New South Wales runs its own energy efficiency schemes that provide additional discounts on eligible heat pump installations when the work is completed by an approved provider. These are separate from the federal certificates and generally stack with them.
What This Means for You
Eligibility depends on the system you choose, the system you are replacing, your property and the current scheme rules, all of which change from time to time. Rather than publish figures that go stale, we will tell you exactly what applies to your situation when we quote, and we handle the paperwork so it is applied correctly.
HOt Water Heat Pump Benefits
Benefits of a Heat Pump Hot Water System
- Much lower running costs, typically around 60 to 75 per cent less electricity than a conventional electric storage tank, which is where the payback comes from.
- Ideal for Sydney's climate, heat pumps work best in mild conditions, and Sydney rarely gets cold enough to trouble a decent unit.
- Works brilliantly with solar; set the timer to run through the middle of the day, and you are heating your water largely on your own rooftop generation.
- Rebates reduce the upfront cost; government incentives currently bring the purchase price much closer to a standard replacement than most people expect.
- No gas connection required, useful if you have no natural gas at the property, or you are moving away from gas entirely.
- Lower emissions, far less energy per litre of hot water, and the footprint drops further again if you have solar.
- Straightforward replacement, for most homes with an existing electric storage tank, it is a like-for-like footprint swap rather than a major renovation.

Excellent service from R&G Plumbing at my unit. Jeremy was very quick to contact me and arrange an inspection. Once here, Adam was professional, punctual, and quickly identified the issue with my kitchen taps. He clearly explained the problem, completed the repair efficiently, and provided all the documentation I needed afterwards.
I really appreciated the honest advice, attention to detail, and fair pricing. I highly recommend R&G Plumbing to anyone looking for reliable, fairly priced, and professional plumbing services.
Thank you again to the entire R&G Plumbing team!

Jack from R&G Plumbing Gas & Drainage Pty Ltd was outstanding from start to finish. His workmanship was excellent, and he was professional, friendly, and incredibly patient throughout the entire job. He went above and beyond to make sure everything was done properly and took the time to explain things clearly, which I really appreciated. The quality of his work speaks for itself, and the pricing was very fair — great value for money. I couldn’t be happier with the result and would highly recommend Jack to anyone needing a reliable and skilled plumber. Thank you Jack

We had a blocked drain in our backyard and R&G Plumbing reached out very quickly. Jeremy gave us a fair quote for jet blasting, so we went ahead. Zac came out and was fantastic. When the jet blasting didn’t work, he found the pipe was completely blocked by long roots and a hole in the pipe
Initially, it looked like the floor would need to be dug up for a 1.5 day job$$, which we couldn’t afford. Instead, Jack kept investigating and found another access point through our neighbour’s carpark ceiling. He organised access to neighbours garage, removed the roots, and repaired the pipe at a much more affordable price. The roots were way worse than we expected.
As a young couple and first home buyers, this was our first time dealing with a plumber and we were pretty stressed since we thought it was a simple blockage but it turned out to be a complex issue. I gotta check the drainage when im purchase property in the future. Learnt my lesson!
Jeremy and Zac explained everything clearly and provided a detailed report and invoice so we can raise it with strata, as the drainage is linked to other units and may have further issues.
Really grateful for the honesty and effort. We’ve definitely found a plumber we trust and would happily connect with Jeremy’s team again.

Very happy with the work and the service. Jack came to give me a quote on replacing 4 taps in the laundry and the Abs came to do the work 2 hours later. Everything fixed quickly on the same day. Both young men were very professional and pleasant. I would recommend them.

My sewer was blocked, and as my normal plumber was unavailable for a week I contacted R&G Plumbing. They promptly attended after my call, and temporarily fixed the problem, but indicated the pipe had to be replaced. After being a bit taken aback by the quote, I accepted due to the urgency of the matter. Abs and his apprentice River (2 days on the job) attended on time a couple of days later to complete the job. Both very pleasant to speak to. It was an all day job to dig the hole through heavy clay, replace the pipe, back fill, and replace a row of pavers. I think they did a pretty good job with the clean up as well. Overall, happy with the reliability and outcome, though I thought a tad expensive. I did ask a general question of replacing 2 washers, and was quoted 3 times more than I actually paid my normal plumber the previous week. Anyway, the job was done to a satisfactory standard, and no complaints. Toss of the coin for 4 or 5 stars, but it came out 4 just for the cost - maybe I live in the past.....?

We had Zac@R&G Plumbing attend a consistently blocking toilet in our apartment. He demonstrated strong knowledge, explaining where he believed the issue lay & what he needed to do to diagnose. On confirming his diagnosis he provided a detailed report so we could provide to our strata manager as issue would require strata approval to fix. Zac was professional, honest & worked efficiently, cleaning up as if he had never been. We would have no hesitation recommending Zac for any plumbing requirement & will definitely use his services again in future. Cheers, Paula

Heat Pump Hot Water FAQs
Is a heat pump hot water system worth it in Sydney?
For most homes, yes, particularly if you are replacing an old electric storage tank. Sydney's mild climate suits the technology, running costs are typically around 60 to 75 per cent lower than conventional electric, and rebates bring the upfront cost down considerably. The savings only materialise if the system is sized and positioned correctly, which is why the assessment matters as much as the unit.
How much does a heat pump hot water system cost in Sydney?
It depends on the size and brand, whether it is integrated or split, and whether any electrical or plumbing changes are needed. Rebates usually reduce the price substantially. We assess your home and give you a fixed price with the rebates already applied, so you see the real figure rather than a headline number, and there is no call-out fee to get one.
What rebates are available for heat pump hot water in NSW?
There are two layers. Federal small-scale technology certificates apply to eligible systems and are normally taken off the price at the point of sale. On top of that, New South Wales runs its own energy efficiency schemes that provide further discounts when the install is done by an approved provider. Eligibility and values change over time, so we will confirm exactly what applies to your situation when we quote.
What are the downsides of a heat pump water heater?
Three genuine ones. The upfront cost is higher than a plain electric tank before rebates. It reheats more slowly than gas, so sizing matters. And it has a fan and compressor, so it makes some noise and needs outdoor air, which limits where it can go. All three are manageable with a proper assessment, and all three cause problems when they are ignored.
How noisy is a heat pump hot water system?
Roughly comparable to an outdoor air conditioning unit, and modern models are quieter than earlier ones. The real variable is placement. A unit sited away from bedroom windows and boundary fences is something you stop noticing, while the same unit under a bedroom window is not. If noise is a concern, a split system lets us put the compressor somewhere sensible.
Can you run out of hot water with a heat pump?
Yes, like any storage system, if you use more than the tank holds. Heat pumps also recover more slowly than gas, so an undersized unit will feel like it runs out constantly. Sized correctly for your household's peak usage, most Sydney homes never think about it.
Do heat pumps work in winter in Sydney?
Yes. They draw heat from ambient air rather than sunlight, so they work day and night and through cold snaps. Efficiency does drop as the air gets colder, and most units include an electric boost element for the rare occasions it is needed. Sydney winters are well within normal operating range.
How long does a heat pump hot water system last?
Around 10 to 15 years with proper installation and regular servicing, and sometimes longer. The compressor is the component that determines lifespan, which is why keeping the air filter and evaporator clean genuinely matters.
Can I run a heat pump on my solar panels?
Yes, and it is one of the best reasons to get one. Setting the timer to heat during the middle of the day means the system is largely running on your own rooftop generation rather than grid power. We set this up during commissioning.
How much space does a heat pump need?
It needs to be outdoors or very well ventilated, with clear space around the unit for airflow and a path for condensate drainage. Exact clearances vary by model. It cannot go in a sealed cupboard or a boxed-in corner, because restricting airflow directly reduces efficiency.
