Hot Water System Replacement Melbourne 2026 — Costs, Rebates & What to Choose
Introduction
Replacing a hot water system in Melbourne costs $900–$7,000 installed depending on the system type. In 2026, eligible households can access up to $1,000 off a heat pump installation through Solar Victoria and additional discounts through the VEU program — reducing the out-of-pocket cost to as low as $599 for many households. Heat pump systems deliver the lowest running costs long-term.
Hot Water Replacement Costs in Melbourne — 2026 Breakdown
When your hot water system fails or reaches end of life, you have three choices: replace like-for-like, upgrade to a heat pump, or go with gas (if connected). In 2026, with gas prices rising and two government rebate programs stacking on heat pumps, the upgrade option makes significantly more financial sense than it did even 2 years ago.
| System Type | Supply + Install | Annual Running Cost | Rebate Available |
| Electric storage (replacement) | $900–$1,400 | $700–$950/yr | None |
| Gas storage (replacement) | $1,200–$1,800 | $350–$550/yr | None |
| Heat pump (integrated, mid-range) | $2,500–$4,500 | $200–$350/yr | Up to $1,000 (Solar Vic) + VEU discount |
| Heat pump after rebates (est.) | $599–$2,500 | $200–$350/yr | Applied upfront |
The Two Rebates Available in Victoria in 2026
Solar Victoria Hot Water Rebate — up to $1,000
Victorian owner-occupiers with a combined household income under $150,000 (updated from $210,000 as of July 1 2026) can access up to $1,000 off an eligible heat pump hot water system. The rebate is applied as a point-of-sale discount — you do not claim it afterwards.
Eligibility:
- Owner-occupier (renters not eligible for this rebate)
- Combined household income under $150,000
- Replacing an existing electric or gas system
- Using a Solar Victoria-registered installer
Important: From 1 July 2026, the income threshold dropped to $150,000. If your household earns above this, you are no longer eligible for the Solar Victoria rebate — but the VEU discount and federal STC rebate still apply
Victorian Energy Upgrades (VEU) Program
The VEU program provides a separate upfront discount on eligible heat pump hot water systems. Unlike the Solar Victoria rebate, this has no income test. The discount is applied at the time of installation and varies based on your postcode, the product, and current VEEC prices.
Evitech is an Accredited Person under the VEU program and applies both the Solar Victoria rebate and VEU discount on your behalf where eligible.
Federal Small-scale Technology Certificates (STCs)
A federal incentive applies to all new heat pump installations. For a 2026 installation in Melbourne (Zone 3), this adds approximately $570–$650 in additional savings depending on the model.
Combined example (eligible household in Melbourne metro):
- Heat pump supply + install: $3,500
- Solar Victoria rebate: -$1,000
- VEU discount: -$400–$800
- STC value: -$600
- Estimated out-of-pocket: $1,100–$1,500
Which System Is Right for Your Melbourne Home?
Replace with electric storage if:
- Your budget is under $1,000 and you need an emergency replacement today
- Short-term rental property where running costs aren’t your concern
Upgrade to heat pump if:
- You plan to stay in the property for 3+ years
- Your household income is under $150,000 (Solar Vic rebate applies)
- You have solar panels (heat pump running during solar hours reduces cost to near zero)
- You’re replacing a gas system and want to reduce your gas bill or disconnect gas entirely
Stick with gas if:
- You have no outdoor space for a heat pump unit
- You already have gas infrastructure and aren’t planning full electrification
