Hot Water From Outside Air
Can winter air warm a shower? A heat pump hot water system is a water heater that draws warmth from outside air into its stored water. Our licensed team installs heat pump water heaters.
Heat Pump Installation Across Sydney
Check your current hot water system and household size, since both show which heat pump installation fits:
-
Solar Timer Setup
If your home has rooftop solar, the NSW Government advises a built-in timer so water warms while panels generate. We set that timer during the install, matching your solar panels.
-
Sizing the Tank
A 340-litre Enviroflo Electric model suits up to six people and a 180-litre one up to three, according to Rinnai. We match heat pump hot water systems to household size.
-
Electric to Heat Pump
Swapping outdoor electric tanks is simpler, because a heat pump often uses similar plumbing and electrical connections, according to Rheem. We remove the old electric tank, which clears the site.
-
NSW Rebate Installs
The NSW heat pump rebate applies when a heat pump replaces an older electric or gas water heater. Before installation, you sign the nomination form assigning the installer the discount.
-
Gas to Heat Pump
When you switch to electric, a licensed gasfitter disconnects the ageing gas tank. Building Commission NSW counts that disconnection as gasfitting, a step in every gas to heat pump swap.
-
Outdoor Unit Placement
Rheem's guide says a heat pump needs open space outdoors so air can circulate. We site the outdoor unit with clear airflow round the fan, away from neighbours' bedroom windows.
How Much Does a Heat Pump Cost in Sydney?
A heat pump costs $2,000 to $6,900 installed in Sydney, the NSW Government and What's The Damage reported in 2026:
| Source | Heat pump price, supplied and installed | Date |
|---|---|---|
| NSW Government | $2,000 to $6,000 | July 2026 |
| What's The Damage | $3,450 to $6,900 | October 2026 |
Both the NSW Government and What's The Damage give these 2026 heat pump hot water prices before any incentive comes off the quote. Tank size, electrical work and gas capping move the quote, What's The Damage notes.
Who Installs a Heat Pump in NSW?
A licensed plumber and/or electrician installs a heat pump, the NSW Government says, splitting the work:
-
Licensed Plumber Work
Building Commission NSW treats installing hot water storage appliances as water plumbing, so a licensed plumber connects the tank. The plumbing work follows AS/NZS 3500.4, the heated water services standard.
-
Electrical Wiring Work
Any electrical wiring work in NSW needs a licensed electrician, whatever the job costs, the NSW Government says. Wiring includes fixed appliances, like a heat pump on its dedicated circuit.
Choosing a Heat Pump for Sydney Homes
A heat pump loses federal certificates when the install differs from its Clean Energy Regulator listing, so weigh five points:
-
Heat Pump or Electric Storage
A heat pump is dearer to buy than electric storage but uses far less electricity, according to What's The Damage. A like-for-like hot water system replacement suits small, low-use households.
-
Winter Operating Range
When cold winter mornings worry you, check each model's range. The AmbiPower MDc-180 keeps heating in air down to -7°C, while the MPi-325 needs 5°C or more, according to Rheem.
-
Backup Element
Check the backup element, an electric heater for air too cold for the compressor. Rheem's guide lists 2.4 kW elements on AmbiPower and Ambiheat models, 3.6 kW on the MPi-325.
-
Registered Models Only
The Clean Energy Regulator's register lists heat pumps of 425 litres or less for small-scale technology certificates, federal credits that cut the price. Ask which listed model a quote includes.
-
Heat Pump or Solar
If shade, a small roof or orientation rules out solar hot water, Rheem's guide suggests a heat pump. Solar suits a sunny roof with room for collectors, according to Rheem.
Why Heat Pump Hot Water Matters
An old electric tank adds to your energy bills every day, and switching brings three gains:
-
Lower Energy Bills
Switching to a heat pump cuts energy bills by $200 to $800 a year against a traditional system, the NSW Government said in 2026. Solar-timed heating lifts the yearly savings.
-
Five-Year Defect Cover
Energy Savings Scheme rules need at least a 5-year defect warranty on heat pumps of 700 litres or less. The cover spans the heat pump, tank and maker's other parts.
-
Fewer Household Emissions
If you want a lower-emission home, check the heat pump's refrigerant. Newer heat pumps use lower global warming potential refrigerants, such as R290 in the AmbiPower 280e, according to Rheem.
Our Process
Our process moves from your first call to a site check, written quote and commissioned heat pump:
-
Your First Call
Ring at any hour and you'll talk to a real person, not a recording. We book your site visit while you're on the call, with Same Day Service across Sydney.
-
Site and Airflow Check
We check the outdoor spot for airflow and distance from neighbours' bedrooms, plus the power supply and tank size. You hear those findings on the spot, before any written quote.
-
Itemised Written Quote
Each itemised written quote carries Best Price Guaranteed. The quote lists electrical work, capping any gas line and taking the old tank away, so your install day brings no surprises.
-
Install and Commission
Our team installs the heat pump and sets the thermostat to 60°C, as the NSW Government advises. We then show you the controls and how to maintain the heat pump.
Common Heat Pump Problems We Fix
The right setup fixes bedroom noise, higher power bills, a tank that's too small and blocked airflow:
-
Noise Near Bedrooms
Heat pump noise shouldn't reach neighbours' bedrooms before 7 am (8 am weekends and public holidays) or after 10 pm, under the Noise Control Regulation 2026. Daytime timing fixes that.
-
Higher Power Bills
If daytime rates eat your savings, ring your retailer about the tariff and reset the timer. Heat pump hours can drift outside off-peak tariff periods, the Energy Savings Scheme notes.
-
Tank Too Small
We swap in a larger, household-matched tank when hot water runs out before the last shower. The NSW Government advises having the installer choose a tank that won't run out.
-
Blocked Airflow
Keep leaves, debris and plants clear of the outdoor unit, as the NSW Government advises. Rheem's guide recommends a yearly plumber check cleaning the filters, part of hot water servicing.
