Electric hot water systems
An electric storage system heats water in an insulated tank and keeps it hot until you need it. When one fails, it usually leaks from the tank or stops heating. We isolate the water and power, take the old unit out, install the new one and test it.
You can compare installed prices for gas and electric systems in our online tool before you book. If your system might be repairable, see hot water repairs.

How an electric hot water replacement works
See prices online, or call 1300 301 354.
We confirm the system and a fixed price, and work begins only when you say yes.
We isolate the water and power and take the old unit out.
We install and test the new one, then take the old one away.
Sizing a new tank
A bigger household needs more stored hot water. In Kellyville, we replaced a leaking 80 litre heater with a 160 litre unit, doubling the storage.
Under-sink units
Small units sit in a cupboard close to where the hot water is used. In Parklea in August 2026, we replaced a rusted-out 25-litre unit in a kitchen cabinet.
What does a new electric hot water system cost?
The price is fixed before any work starts. It depends on:
- The size of the tank.
- The brand and model you choose.
- Access to where it’s installed.
Installed prices for gas and electric systems are in our online tool, so you can compare them before you book.
