Repair or Replace?

Signs It's Time for a Hot Water System Replacement

A sound tank is often worth repairing — but these signs usually mean a replacement is the smarter, cheaper choice.

10–15+ Years Old

Most tanks last 10–15 years. Past that, a replacement is usually cheaper than ongoing repairs.

Leaking Tank

Water pooling under the unit means the cylinder has failed — that can't be repaired and needs replacing.

Rusty or Discoloured Water

Brown or metallic hot water points to internal corrosion in the tank.

Running Out of Hot Water

Shorter and shorter hot showers, or water that never gets properly hot, signals a dying system.

Repeated Breakdowns

If you're calling for repairs again and again, a new system quickly pays for itself.

Rising Energy Bills

An old, inefficient unit costs more to run — a modern replacement can slash your hot water bills.

Not sure whether to repair or replace? We give honest advice and a free quote on both — see our repairs, or call 1300 728 122.

FAQs

Hot Water System Replacement — Frequently Asked Questions

How do I know if I need a hot water system replacement?
The usual signs are age (most systems last 10–15 years), a leaking tank, rusty or discoloured hot water, running out of hot water, repeated breakdowns or rising energy bills. A leaking cylinder can't be repaired and needs replacing. If you're unsure, we give honest advice and a free quote on whether to repair or replace.
How much does hot water system replacement cost?

It depends on the type and size of system, where it's located and how complex the changeover is. Electric is usually the most affordable like-for-like replacement, while solar and heat pump systems cost more upfront but can dramatically cut running costs. We provide a free, no-obligation quote so you know the price before any work starts.

Can you replace my hot water system the same day?
In most cases, yes. We carry common systems and parts, so a straightforward like-for-like replacement is often completed same-day — important when you've got no hot water. Call us on 1300 728 122 and we'll get you sorted fast.
Should I replace like-for-like or upgrade to a more efficient system?
Replacing is the perfect time to consider an upgrade. Moving to a heat pump or solar hot water system can cut your running costs significantly, while a like-for-like electric or gas swap is the quickest, most affordable option. We'll advise on what suits your home and budget.
Do you remove and dispose of my old hot water system?
Yes. We manage the full changeover — safely disconnecting, removing and disposing of your old unit, then installing and commissioning the new system to code, with genuine parts where needed.
Which brands of hot water systems can you supply and install?
We supply and install all major brands, including OMNI X, Rheem, AquaMAX, iHeat, iStore, Apricus, Reclaim, Vulcan, Haier, EvoHeat, Thermastore, Rinnai, Bosch, Stiebel Eltron and Dux. We'll help you choose the right system and size for your household.

We replace hot water systems across the Sunshine Coast, Brisbane, Bribie Island and Gympie — same-day in most cases.
