Hot Water Cost

A Victorian heat pump, worked through

Two reductions, applied in a set order. Seeing them run in sequence explains why the headline numbers never simply add up.

Last checked

On a $4,000 heat pump quote, the Victorian Energy Upgrades discount comes off first, then the Solar Victoria rebate is worked out on what is left. That order matters: it is why the two headline figures do not simply add together.

Victoria is the most generous state for this swap and the most confusing one to price. Two programs, two sets of paperwork, two different bodies, and a rebate that is a percentage rather than a flat amount. Here is one quote taken all the way through.

Step 1: the quote

Installed heat pump systems run $3,000–$5,200 in Australia. Take $4,000 as a mid-range quote for an eligible system. Your installer's quoted price already includes the federal STC discount, so the federal discount is not a further reduction to come.

Step 2: the Victorian Energy Upgrades discount

An accredited provider takes this off the price at the point of sale. Installers report about $630 when a heat pump replaces an electric system. That leaves $3,370.

The discount is tied to the price of energy efficiency certificates, so it moves with the market rather than sitting at a fixed amount. There is also a floor: installers report a minimum customer contribution of $200, so an upgrade is never free. Treat a $0 offer as a reason to ask more questions.

Step 3: the Solar Victoria rebate

The rebate is 50% of the price, capped at up to $1,000. Half of $3,370 is $1,685, which is above the cap, so the rebate lands at $1,000 and you pay $2,370.

A $4,000 heat pump quote in Victoria, step by step

A worked example, not a price. The quote is a round figure inside the sourced installed-price range; both reductions come from the sourced figures below and change with the certificate market and your eligibility.

Item Figure Before
Installer quote $4,000
After the VEU discount $3,370 $4,000
After the Solar Victoria rebate $2,370 $4,000

The combined reduction here is $1,630, which matches what installers report for eligible systems: up to $1,630. For a product on the locally made list the rebate cap is higher again.

How a heat pump hot water system works Outside air passes over a fan. A compressor raises the temperature of the refrigerant. The heat is transferred into the water tank, and cooler air is blown back out. Outside air Fan and compressor heat cooled air out Water tank Hot water
Fig. 1 — A heat pump does not make heat with an element. It moves warmth out of the outside air into the tank, which is why it uses a fraction of the electricity of a resistive system.

Whether you qualify

The Solar Victoria half has real eligibility rules, and most refusals come down to one of these:

  • You are the owner-occupier of an existing home.
  • Combined taxable income of all owners is under $150,000.
  • The property is valued under $3 million.
  • The system being replaced is at least 3 years old.

The Victorian Energy Upgrades discount has no income test, so a household that misses the rebate can still get the discount. That is the case where the arithmetic above stops at step 2.

What to ask your installer

  1. Is this model on the Solar Victoria approved products list?
  2. What VEU discount are you applying today, in dollars?
  3. What is the price before both reductions, and what do I pay on the day?

The calculator runs the same sequence for other states and system types, and the Victoria rebate page has the program detail.
