When your hot water stops working, you need fast answers. Below are the most common questions Melbourne homeowners ask before replacing a hot water system — including costs, timing, and what type of unit is best for your home.

Q: How do I know if my hot water system needs replacing?

If your hot water unit is over 10 years old, leaking, rusting around the base, or no longer producing consistent hot water, it’s usually time to replace it. Repairing an old or corroded system often costs more long-term than a new, efficient model.

Q: Can any plumber replace a hot water system?

No — in Victoria, only a licensed plumber can install or replace a hot water system. Every installation must meet VBA regulations and come with a Certificate of Compliance for safety and warranty protection.

Q: How much does a replacement hot water unit cost?

It depends on the system type and size:
• Gas storage units: typically $1,700 – $2,500 installed
• Continuous-flow gas: $1,800 – $2,800 installed
• Electric or heat-pump: from $1,900 + installation
Prices include removal of the old unit and issuing a VBA certificate. We always provide a fixed written quote before starting any work.

Q: Can I switch from gas to electric or heat-pump?

Yes — many homeowners are switching to efficient electric heat-pump systems. They’re quieter, cheaper to run, and work well with solar setups. We’ll check your existing plumbing and power connections to recommend the right upgrade.

Q: How quickly can a plumber replace a failed unit?

We offer same-day or next-day replacements for most systems across Melbourne’s western suburbs. If your old unit has burst or stopped completely, we’ll prioritise your job so you’re not without hot water overnight.

Q: What brands of hot water systems do you install?

We supply and install quality brands such as Rheem, Rinnai, Vulcan, Thermann, and Bosch, backed by full manufacturer warranties and VBA-compliant installation.
