Heat pump hot water, installed properly, across NSW and the ACT
Hot water is the second biggest energy user in most Australian homes. A heat pump water heater does the same job as an electric storage tank while drawing a fraction of the power, because it moves heat from the air instead of making it with an element. We size it, site it, install it and take the old unit away.
- All-in-one systems in 220 L, 270 L and 320 L, with or without an electric backup element
- Licensed plumbing and electrical work, one crew, one visit on most jobs
- Your old water heater disconnected, removed and sent for recycling
- The NSW Hot Water Upgrade Incentive explained on the quote, not after the install
A heat pump is not the right answer for every house. Where the only suitable position is under a bedroom window, or the tank has to sit inside an unventilated cupboard, we will tell you so and quote the alternative instead.
A fridge running backwards, pointed at your tank
An electric storage heater turns one unit of electricity into one unit of heat. A heat pump uses that unit of electricity to run a compressor and a fan, and harvests heat out of the outside air. That is the whole idea, and it is why the running cost is lower and why the unit has a fan you can hear.
It needs air, and space around it
The compressor sits on top of the tank and breathes. Enclose it in a tight cupboard and it will work harder, run longer and complain. Clearances come off the manufacturer's install manual, and we check them on site before quoting.
It is slower to recover
A heat pump reheats a tank gently rather than in a rush. That is fine with the right tank volume for the household and a nuisance if the tank is undersized. Sizing is the single decision that determines whether you like the thing.
It makes a noise
Not loud, but not silent either. Siting matters more here than on any other appliance we install. Tell us which wall your bedroom is on, and which wall is your neighbour's.
The systems we install
All-in-one heat pump water heaters, supplied through our wholesale channel. Tank volume is the decision that matters most, and the second decision is whether you want a built-in electric backup element. Models without the element use an Easy Fit Kit for the electrical connection.

The discount comes off the quote, and the paperwork comes first
The NSW Government runs a hot water upgrade incentive through the Energy Savings Scheme. It is not a rebate you claim back after the fact. It arrives as an upfront discount inside the installer's quote, and the form that secures it has to be signed before anybody touches your old tank. Work already completed cannot be paid for retrospectively.
Get more than one quote
The scheme is explicit about this, and so are we. Ask every installer whether the incentive is included and whether the discount is shown on the quote. Compare what is actually installed, not just the headline number.
Choose the system
Not every model attracts the incentive, and two models of the same tank volume can attract different amounts, because the figure is based on the energy saving of the new system against the old one. Settle volume, siting, noise and warranty here.
Sign the nomination form before work starts
This is the step people miss. The nomination form and the quote both get signed first. You may also be asked for documents proving eligibility.
Installation, then the declaration
A licensed plumber and electrician install the system, show you how to run it, and remove the old heater for recycling. Afterwards you sign a Post Implementation Declaration and the installer photographs the completed work for the scheme record.
Incentive mechanics and the indicative discount amounts on this page are drawn from the NSW Government's published guidance on the hot water upgrade incentive, last updated 6 February 2026. The Energy Savings Scheme is administered by the Independent Pricing and Regulatory Tribunal. Nothing on this page is an offer of a specific discount.
Heat the water with the power you are already exporting
Export rates have fallen far enough that sending midday generation to the grid is the least valuable thing you can do with it. A hot water tank is a battery that stores heat instead of electricity, and it is the cheapest one you will ever own. Set the heat pump to run in the middle of the day and the energy it uses is energy you were giving away.
- A timer or the unit's own schedule shifts the heating block into daylight hours
- No change to the solar system itself on most homes
- Works alongside a battery rather than competing with it — heat first, store what is left
- If you have no solar yet, the hot water upgrade and the solar install can be designed together
What actually happens on the day
- The old water heater is isolated, drained, disconnected and removed from site
- The new unit is positioned with the manufacturer's clearances respected, on a base that will still be level in ten years
- Plumbing connections, tempering valve and a drain line that goes somewhere sensible
- Electrical connection by a licensed electrician, with the isolator and circuit protection the model requires
- Commissioning, a first heat cycle, and a walk through the controls and the timer with you
- The old unit goes for recycling or disposal, and the scheme paperwork is completed
Most straight swaps are a single visit. Jobs that need a new circuit from the switchboard, a relocation to a different wall, or a concrete base poured will be quoted as two visits, and we will say so before you book rather than on the day.

What people ask before they commit
Will a heat pump fit where my old tank is?
Usually. An all-in-one heat pump is a tank with the compressor on top, so it occupies a similar footprint to a storage tank of the same volume but stands taller and needs clear air around it. We measure the space, the clearances and the drainage on site before we quote.
Is it noisy?
A heat pump has a fan and a compressor, so it is not silent the way an electric element is. Noise is the reason siting matters: away from a bedroom window and away from a neighbour's. Ask for the manufacturer's sound rating for the model you are quoted, and tell us where the quiet side of the house is.
Do I need solar to run one?
No. A heat pump water heater works on grid power alone. If you already have solar, a timer that runs the heat pump in the middle of the day uses your own generation instead of exporting it.
What happens to my old water heater?
It is disconnected, removed and sent for recycling or disposal as part of the job. You do not have to arrange that separately.
Can I keep using it in a blackout?
No, not unless it is on a backed-up circuit. A heat pump needs power to run. Water already in the tank stays hot for a long time, so a short outage is rarely noticed.
My hot water has already failed. How fast can you come?
Tell us when you call and we will treat it as a replacement rather than an upgrade, because the sequence is different and the incentive paperwork still has to be signed first. Call 1800 38 50 38 rather than using the form.
Get the model, the discount and the total on one page
A hot water quote that names the model, shows the incentive as a line item and states what the installation includes is a quote you can compare. That is the only kind we send.
Or call 1800 38 50 38. Upgrading more than hot water? The NSW zero-interest loan can cover several upgrades in one application. Already have solar and want the tank running on it? Start with residential solar.
