Electric Hot Water - Simple and Reliable
Electric hot water systems are the most straightforward option available. They’re simple to install, require no gas connection, and provide reliable hot water. However, they’re the most expensive to run of all system types.
When Electric Makes Sense
Electric systems can be appropriate for:
- Rental properties where upfront cost matters most
- Small households with low hot water usage
- Temporary solutions while planning a more efficient upgrade
- Properties without gas where heat pump space isn’t available
The Honest Truth About Running Costs
We believe in honest advice. For most Perth households, an electric storage system will cost $800-$1,200 per year to run. A heat pump doing the same job typically costs $200-$400. Over a 10-year system life, that’s thousands in savings.
If budget allows, we recommend considering a heat pump upgrade. The higher upfront cost is usually recovered within 3-5 years through energy savings.
Off-Peak Electricity Options
If staying with electric, consider off-peak tariffs:
- Controlled load tariff - Electricity supplier controls when heating occurs
- Time-of-use tariff - Heat during designated off-peak hours
- Larger tank needed - Must provide enough hot water through peak periods
Off-peak can reduce running costs by 30-50%, making electric more competitive with gas.
Types of Electric Systems
Storage Systems
- Tank constantly maintains hot water temperature
- Available in 125L to 400L+ capacities
- Simple, reliable technology
- Higher standing losses (heat escaping from tank)
Instantaneous
- Heats water only when tap is opened
- Very compact, suitable for single points of use
- Limited flow rate (usually single tap at a time)
- Lower running cost but restricted application

Frequently Asked Questions
Electric resistance heating is simple and the units are straightforward to manufacture. However, converting electricity directly to heat is inefficient compared to heat pumps that move heat rather than create it.
