Should You Repair or Replace Your Hot Water System?
Water leaking from the tank itself
A confirmed leak from a corroded storage tank generally means the system needs replacing.
Rusty or discoloured hot water
This can indicate corrosion inside the tank, although other causes are possible. We’ll investigate before recommending a replacement.
Frequent breakdowns
If your system is ageing and needs repeated repairs, replacement may be the more economical option.
No hot water, but no visible leak
A faulty component may be responsible. Depending on the system’s age and condition, a repair could restore your hot water.
No hot water, but no visible leakA relief valve that keeps running or dripping excessively
The valve or water pressure may need attention. This doesn’t necessarily mean the whole system needs replacing.
We’ll explain the issue, recommend whether repair or replacement makes sense, and provide an upfront price before work begins.

Hot water replacement questions
Have another question? Call 0448 984 771 – we’re happy to help.
How much does a new hot water system cost to install?
The total comes down to the system you choose, its size, and how much work the setup needs. Where the tank sits matters too, and so do the valves and pipes around it. We look at what you've got now and give you a price for the new one, fitted, before any work starts.
How long should a hot water system last?
It varies a lot. Water quality, how hard the system works, and whether the relief valve gets checked all play a part. Many tanks give years of good service, then start showing rust, leaks or lukewarm water. Once a tank itself starts leaking, it's at the end of its life and needs replacing.
Is there a rebate on hot water systems in Victoria?
Solar Victoria offers rebates on eligible heat pump and solar hot water systems. They're for owner-occupiers who meet an income test and are replacing an existing system. The rules change, so check solar.vic.gov.au for what applies to you. Ask us when you ring and we'll tell you if it's a system we can fit.
Who replaces a hot water system?
Usually a plumber, sometimes with help on the power side. A plumber does the water side: taking the old tank out, fitting the new one, and connecting the pipes and valves. On an electric system, the power connection needs someone licensed to work on power. Ask us when you ring and we'll explain how the power side gets done on your job.
Can you replace it the same day?
We can often come out the same day you call, work out what you need and give you the price. Whether the new system goes in that day depends on which one you choose and getting it to your place. Ask when you ring and we'll tell you what to expect for your job.
Can a bigger tank go in the same spot?
Sometimes. A bigger tank is taller or wider, so it has to fit the space, the base it sits on and the pipes around it. We'll check the spot when we come out and tell you what fits before you choose.
Will a new hot water system lower my energy bills?
It depends on what goes in. A new tank of the same type uses about the same energy, though it may hold its heat a little better than a worn one. A heat pump uses a lot less power than a standard electric tank. If your old tank was leaking hot water, that waste stops once it's replaced.
Should I stick with the same brand?
You don't have to. We fit most of the big brands. Tell us what you've got now and what you'd like, and we'll tell you which systems suit your home and fit the space.
