Heat pump hot water systems — assessed, quoted and installed end to end
What Is A Heat Pump Hot Water System?
A heat pump hot water system works like a refrigerator in reverse: it draws heat from the surrounding air and transfers it into a storage tank. Because it moves existing heat rather than generating it with a resistance element, it typically uses a fraction of the electricity of a conventional electric storage system.
Ausgreen Solar Solutions assesses your household's hot water demand, available space and electrical setup, then recommends and installs the right heat pump system — including how it can run off your own rooftop solar during the day.
🏛️ Government Incentives May Cut The Upfront Cost
Eligible heat pump hot water installations can attract Small-scale Technology Certificates (STCs) and, depending on your state, additional state-based energy efficiency schemes. Eligibility depends on the specific model, the system it replaces, installation date and location — our team confirms current entitlements as part of your quote.
Heat Pump vs Other Hot Water Systems
A general guide to how the common system types compare for a typical household.
| System Type | Running Cost | Energy Source | Best For |
|---|---|---|---|
| Heat Pump | Low | Electricity + ambient air heat | Households wanting the lowest electric running cost, especially with solar |
| Electric Storage | High | Electricity (resistance element) | Low upfront cost, limited space or very low hot water use |
| Gas Storage / Instant | Medium–High | Natural gas or LPG | Existing gas connections; ongoing gas supply charges apply |
| Solar Thermal | Low | Roof-mounted solar collectors | Sunny sites with suitable roof space and a booster |
ℹ️ Savings Depend On Your Household
Actual savings depend on your current system, hot water usage, electricity tariff, climate and whether you run the unit off solar. Your Ausgreen quote estimates this for your specific home.
Benefits Of A Heat Pump Hot Water System
Lower running costs, lower emissions and a natural fit with rooftop solar.
Much Lower Energy Use
By moving heat rather than creating it, a heat pump typically uses far less electricity than a standard electric storage system.
Runs On Your Solar
Many systems can be scheduled to heat water during the day, using surplus solar generation instead of grid power.
Lower Emissions
Reduce your household's greenhouse gas footprint, particularly when replacing gas or electric resistance heating.
Incentive Eligible
Eligible models and installations may qualify for STCs and state schemes, confirmed on your quote.
Reliable Hot Water
Storage tank design delivers consistent hot water for showers, laundry and the kitchen, with a boost mode for peak demand.
Gas-Free Option
Move hot water off gas and reduce ongoing supply charges as part of a broader electrification plan.
Battery & EV Ready
Pairs well with a home battery or EV charging setup for a more complete energy system.
Smarter Control
Add visibility and scheduling with SkyBox Energy Management to shift hot water heating to the cheapest or sunniest hours.

What A Well-Run Heat Pump Project Looks Like
A hot water system lasts a decade or more. These are the things worth getting right from the start.
- Confirm your installer is licensed and check their track record independently
- Size the tank to your household's real daily hot water use
- Check the unit location has enough airflow, clearance and acceptable noise levels
- Confirm your switchboard can support the new unit
- Get an itemised quote that separates the unit, installation, removal and any incentive
- Ask for the product and workmanship warranty terms in writing
- If you have solar, ask how the unit will be scheduled to use it
- Choosing a unit on upfront price alone without checking running costs
- Undersizing or oversizing the tank for the household
- Placing the unit where airflow is restricted or noise affects neighbours
- Assuming every model qualifies for the same incentive
- Ignoring the switchboard and electrical requirements
- Running the unit only at night when solar could power it by day
Incentives That Can Reduce Your Hot Water Upgrade Cost
Depending on your location, eligibility and the specific system, several schemes may apply to your installation.

Frequently Asked Questions
How does a heat pump hot water system work?
It uses a compressor and refrigerant to extract heat from the surrounding air and transfer it to water in a storage tank. Because it moves heat instead of generating it, it uses much less electricity than a resistance-element system.
How much can I save with a heat pump hot water system?
Savings vary with your current system, hot water usage, tariff and climate. Heat pumps typically use substantially less energy than electric storage systems, and savings can increase if the unit runs on your own solar. Your quote includes an estimate for your household.
Do heat pumps work in cooler weather?
Yes. Modern heat pump water heaters are designed to operate in a wide range of ambient temperatures, and most include a boost mode for extreme cold or heavy demand. We recommend a suitable model for your location during the site assessment.
Can I run a heat pump off my solar panels?
In most cases, yes. Many systems can be scheduled or controlled to heat water during sunny hours, making use of surplus solar generation. We can also add SkyBox Energy Management for more detailed control.
Are there rebates for heat pump hot water systems?
Eligible systems may qualify for STCs and state-based schemes. Eligibility depends on the model, the system being replaced, your location and the installation date. We confirm current entitlements as part of your itemised quote.
Is a heat pump noisy?
Heat pumps produce some operating noise similar to a small air conditioner outdoor unit. Placement matters, so we check the location relative to bedrooms and neighbouring properties during the site assessment.
