How Do I Know My Hot Water System Needs Replacing?
Act now — urgent
No hot water, visible leaking, water pooling around the base, or a burst tank. Call immediately — continuing to run a leaking system risks water damage.
Book within days — warning signs
Rusty or discoloured water, rumbling or banging noises, or inconsistent temperature. Still working, but failure could come at any time.
Plan ahead — age-related
Storage systems typically last 8–12 years. If yours is approaching or past that age, replacing proactively avoids an emergency and lets you compare options properly.
Like-for-Like vs Upgrading — Your Replacement Options
When your system fails, you have a choice: replace it with the same type, fast, or upgrade to a heat pump for a similar net cost after rebates. Here's the honest comparison.
| Option | Installed cost | Speed | Running cost | Rebate available |
|---|---|---|---|---|
| Like-for-like electric | $800–$1,800 | Fastest — same-day possible | ~$900–1,400/yr | ❌ None |
| Like-for-like gas | $1,200–$2,500 | Fast — 1–2 days | ~$400–700/yr | ❌ None |
| ⭐ Upgrade to heat pump | $2,500–$4,500 (before rebates) | Same-day emergency provision available | ~$200–350/yr | ✅ Up to $1,400 + VEU, even for emergencies |
After Victorian rebates, upgrading to a heat pump is often close to a like-for-like electric replacement in net cost — while cutting running costs by 60-75%. Supply Solar quotes both options so you can compare before deciding.

Pair Your Heat Pump With Solar — and Run It for Free
Set and forget: hot water from sunshine
A heat pump can be programmed to run between 10am and 3pm — when a typical solar system is generating peak surplus electricity. Your panels power the heat pump, which heats your water, at effectively zero cost.
Add a home battery and the heat pump can run from stored solar in the evening too — giving you near-complete energy independence for hot water, year-round.
Add Solar to Your QuoteEstimates based on Melbourne tariffs and average 4-person household. Actual results vary.
Do I Need Council Approval to Replace It?
Like-for-like, same spot
Generally no approval needed — the most common scenario, and the fastest to complete.
Changing system type
Switching gas to electric with new external equipment may need sign-off. We confirm this during assessment.
Relocating the unit
Moving the system to a new position on the property can trigger planning requirements depending on your council.
We check it for you
Supply Solar confirms any requirements as part of the free assessment — before you're committed to anything.

What Melbourne Homeowners Say
"Tank started leaking on a Saturday morning. Called Supply Solar, they had someone out same day and replaced it with a heat pump before dinner. Didn't think that kind of turnaround was possible."
"Worried we'd miss the rebate because the old tank died without warning. They explained the emergency provision, sorted the paperwork after, and the $1,400 still came through."
"Noticed rust in the water and a rumbling noise, so booked before it actually failed. Glad we did — they showed us photos of the corrosion once it was out. Good timing on our part."
