Electric hot water systems are the most common type in Melbourne rental properties and apartments. They’re simpler to install than gas (no flue or gas connection required), but have higher running costs than modern alternatives. Here’s a complete guide for Melbourne homeowners and landlords.
Types of Electric Hot Water Systems
Electric storage systems heat and store a tank of water using an electric element. The most common type in Melbourne apartments. Off-peak tariff versions heat overnight when electricity is cheapest. Tank sizes range from 25L (single person) to 400L (large family). Simple and reliable, but standby heat losses reduce efficiency.
Continuous flow electric systems heat water instantly as it flows through the unit, using no storage tank. High power demand (typically 15-36kW) means they require dedicated high-amperage electrical circuits. Used in Melbourne apartments where gas is unavailable and space is very limited. Higher running cost per litre of hot water than storage on off-peak.
Electric vs Heat Pump: The Melbourne Choice
If you have an electric storage hot water system in Melbourne, replacing it with a heat pump when it reaches end of life is strongly worth considering. Heat pump systems use the same electrical connection but deliver 3-4x the hot water per kWh consumed. Victorian Government rebates reduce the upfront cost significantly. A heat pump replaces a 250L electric storage system and typically pays back the cost premium within 3-5 years through energy savings.
Electric Hot Water Running Costs in Melbourne
A 250L electric storage system for a 4-person Melbourne household costs approximately $700-$1,000 per year on standard tariff, or $400-$600 per year on off-peak tariff. A heat pump system for the same household costs $300-$450 per year. A gas continuous flow system costs $400-$600 per year at current Melbourne gas prices. Energy costs change — these are approximate figures for comparison.
Electric Hot Water Replacement Cost in Melbourne
A like-for-like electric storage system replacement (250L) costs $900-$1,400 supply and install. Off-peak or controlled load connection requirements are handled by the electrician. A heat pump replacement costs $2,500-$4,500 before rebates, $1,500-$3,000 after applying the Solar Homes Program rebate and STCs for eligible households.
