Why Homeowners Choose On Electrical for Hot Water Connections
» The Electrical Side Done Properly
A new electric hot water system needs its own dedicated circuit, sized correctly for what the unit draws. On Electrical handles that connection so the system runs safely from day one.
» Local and Easy to Get Hold Of
Based in Clontarf, not squeezed in between jobs on the other side of Brisbane. Being local means less time on the road and more flexibility to fit a job in when it actually suits.
» Isolation Switches Fitter Where They’re Needed
An isolation switch near the unit means it can be safely switched off for servicing or in an emergency, without needing to go anywhere near the main switchboard.
» Works Alongside Whoever Else Is On Site
Whether it’s a straight system replacement or part of a bigger renovation, the electrical connection gets scheduled in when it’s actually needed.
What Happens When On Electrical Comes Out
Most electric hot water connections are completed in a single visit.
The job starts with a check of the existing circuit and switchboard, to confirm what’s needed for the new or replacement system. Older homes on the peninsula sometimes have circuits that were never sized for a modern electric hot water unit, so this gets sorted before anything’s connected.
Once that’s confirmed, the unit is wired to a dedicated circuit and an isolation switch is fitted somewhere it can actually be used. Everything is tested once connected, so the system is confirmed working and you don’t experience any cold showers.

Frequently Asked Questions
Does a new hot water system need its own circuit?
Yes, an electric hot water system needs a dedicated circuit sized correctly for the unit. It’s not something that can share a circuit with other appliances.
Is an isolation switch required?
Yes, and it needs to be fitted somewhere it can actually be reached, so the system can be safely switched off for servicing without going near the switchboard.
Can older homes on the peninsula handle a new electric hot water system?
Sometimes the existing circuit isn’t up to it. That gets checked before anything’s connected, and upgraded if needed.
Is this covered as part of a bigger renovation?
Yes, the electrical connection gets scheduled in alongside whatever else is happening on site.
How long does the electrical connection usually take?
Most jobs are completed in a single visit, tested and confirmed working before it’s called done.
