Quick answer

Heat pump hot water systems usually cost $2,000-$6,000 installed after incentives.

Final price depends on tank size, brand, access, plumbing changes, electrical requirements and current incentive eligibility. A medium 250-315L system is the common family option, while larger households often need 315-400L capacity.

Ask installers to show the before-incentive price, each incentive applied, the final out-of-pocket cost, old-system removal, electrical exclusions and warranty coverage.

Typical installed cost

$2k-$6k

After applicable incentives, depending on tank size, brand, access and site work.

Energy saving

50-75%

Compared with many older electric storage hot water systems.

Install time

4-6 hrs

Most standard replacements are completed in a single visit.

Expected lifespan

10-15 yrs

With correct installation, airflow clearance and regular servicing.

A good installer checks household usage, airflow clearance, drainage, plumbing compliance, electrical supply and current incentive rules before recommending a unit.

Old system removal

Disconnect, drain and remove the existing hot water unit where practical.

System sizing

Match tank size and recovery rate to household size, climate and usage pattern.

Plumbing and valves

Install compliant pipework, tempering valve, drainage and pressure controls.

Electrical coordination

Confirm whether a licensed electrician is needed for circuit or isolator work.

Incentive paperwork

Itemise current STC, state, council, retailer or energy-efficiency program eligibility.

Handover

Test performance, explain settings, warranty requirements and basic maintenance.

Running cost comparison

Why homeowners switch from electric or gas hot water

Heat pumps use electricity to move heat from air into water, instead of creating heat directly. That is why the running cost can be much lower than older electric storage systems.

System Typical yearly cost Notes
Old electric storage $700-$1,000/year Simple but power hungry, especially on peak tariffs.
Gas storage or instant $450-$800/year Depends on gas price, household use and appliance condition.
Heat pump hot water $200-$350/year Moves heat from air instead of generating heat directly.
Solar hot water $150-$350/year Can be efficient, but roof access, shading and boost costs matter.

Savings calculator

Estimate the payoff before you replace your hot water system.

A heat pump upgrade is usually strongest when replacing electric storage hot water. Use quote comparisons to check the installed price, the current incentives and the likely running-cost reduction.

Best-case savings come from off-peak friendly settings, good airflow, correct tank sizing and replacing an older electric unit. Ask installers to show expected annual usage assumptions.

Energy reduction

50-75%

Heat pumps move heat from air into water, using far less electricity than older storage systems.

Annual saving

$300-$600

Typical savings depend on tariff, household usage, climate and the system being replaced.

Payback period

3-6 years

Current incentives can shorten payback when the product and household are eligible.

10 year impact

$3k-$6k

Longer-term savings are strongest when replacing peak-rate electric storage hot water.

Current electric storage

$800-$1,000/year

High energy use, especially on peak tariffs.

Heat pump estimate

$200-$350/year

Lower running cost with efficient heat transfer.

Typical yearly saving

$300-$600/year

Varies with tariff, usage, climate and system settings.

Are heat pumps better than solar hot water?

Heat pumps are often more flexible and reliable. Advantages: work 24/7 with no sun required, lower upfront cost, easier installation with no roof work, and better performance for shaded properties. Solar hot water can suit sunny sites with roof space. Many homeowners choose heat pumps because they work in varied weather, have simpler installation requirements and may qualify for current energy-efficiency incentives.

How much will a heat pump save on energy bills?

Heat pumps can save 50-75% on water heating costs. Typical savings: electric storage heater $800/year to heat pump $200-$300/year, gas heater $500/year to heat pump $200-$300/year, annual savings around $300-$600/year. Payback period is commonly 3-6 years after applicable incentives. Over 10 years, many households save $3,000-$6,000.

What government rebates are available?

Common heat pump hot water incentives may include federal STC certificate discounts and state energy-efficiency schemes such as Victoria Solar Homes, NSW Energy Savings Scheme certificates, Queensland programs, South Australian programs and ACT support. Ask installers to itemise current incentives and documentation in each quote.
8

How long does heat pump installation take?
