Hot Water Questions From Perth Homeowners

If your hot water system is electric or a heat pump, you'll generally need both a plumber and a licensed electrician. The plumber installs the unit and pipework, while we safely disconnect the old electrical supply, wire the new system and ensure everything complies with Australian standards.

Yes. We install and connect standard electric storage hot water systems as well as modern energy-efficient heat pump systems for homes across Perth. We can also advise if your switchboard or electrical supply needs upgrading before installation.

Absolutely. We disconnect the existing electrical supply, install new wiring where required, connect the replacement unit and test everything before it's switched on.

Not always. If your existing switchboard doesn't have enough capacity, lacks safety switches, or doesn't meet current standards, we may recommend a switchboard upgrade before installing the new hot water system.

Yes. Many new hot water systems require their own dedicated electrical circuit to operate safely and comply with Australian wiring regulations.

Most electrical connections can be completed in a few hours. If additional work is needed, such as upgrading your switchboard or installing new cabling, the job may take longer.

Yes. We can connect hot water systems to off-peak electricity tariffs where available, helping reduce your ongoing energy costs.

Yes. Heat pump systems are becoming increasingly popular because they're far more energy efficient than traditional electric storage systems. We provide the electrical installation required to safely connect these units.

A hot water system that repeatedly trips the safety switch may indicate a faulty heating element, thermostat, wiring fault or moisture inside the unit. We can inspect the electrical components and identify the cause before recommending repairs or replacement.

Yes. We provide hot water system electrical installations, replacements and electrical upgrades across Perth and surrounding suburbs. If you're unsure whether we service your area, simply get in touch.
