Electric Hot Water Systems in Canberra
Electric hot water is one of the most common ways Canberra homes heat their water. It’s reliable, simple to run and can be a smart option when it’s matched to the right tariff and tank size. On this page we’ll walk you through the main types of electric hot water systems and how they compare.
1. Electric Storage Hot Water (Tank Systems)
These are the classic “electric tank” systems you see in many Canberra homes. Water is stored in an insulated cylinder and kept hot with an electric element.
Pros
Cons
- Simple, proven technology with easy repairs
- Lower upfront cost than many other systems
- Can run on off‑peak or controlled‑load tariffs
- Works well in homes without gas connected
- Can be more expensive to run on standard tariffs
- Heat loss from older or poorly insulated tanks
- You can “run out” of hot water if the tank is undersized
- Larger tanks take up more space
2. Electric Instant / Continuous Flow
Electric instant systems heat water on demand as it passes through the unit, rather than storing it in a tank.
Pros
Cons
- No storage losses – you only heat water when you use it
- Compact size, ideal for tight spaces or apartments
- “Endless” hot water for busy households
- Often need a high electrical supply and sometimes switchboard upgrades
- Running costs can be high on standard tariffs with heavy use
- Not suitable for homes with limited electrical capacity
3. Heat Pump Hot Water (High‑Efficiency Electric)
Heat pump systems are technically electric, but they work more like a reverse‑cycle air conditioner for your hot water. They move heat from the air into the water instead of creating heat directly.
Pros
Cons
- Uses far less electricity than a standard electric tank
- Great for cutting energy bills and emissions
- Pairs well with solar PV
- May be eligible for rebates or incentives
- Higher upfront cost than a basic electric tank
- Works best in mild to warm conditions
- Fan and compressor make some noise, so placement matters
- More complex technology than a simple element
Which Electric Hot Water System Is Right for You?
When we help Canberra homeowners choose a system, we look at:
- How many people live in the home and how you use hot water
- Whether you have (or plan to install) solar panels
- Your current electricity and/or gas tariffs
- Space available for a tank or outdoor unit
- Your budget now vs how much you want to save long‑term

Cost Comparison: Electric vs Gas vs High‑Efficiency
This is a general guide only. Actual costs depend on your tariff, usage and the exact system.
Upfront costs
- Standard electric storage: lowest upfront
- Gas storage/continuous flow: mid‑range
- Heat pump: highest upfront, but often offset by lower running costs
Running costs
- Standard electric storage on standard tariff: usually the highest
- Gas systems: moderate running costs where gas is available
- Heat pump: usually the lowest running costs, especially with solar
When Electric Makes the Most Sense
- You don’t have gas connected and don’t want the cost of adding it.
- You have (or plan to install) solar panels and want to use your own power.
- You prefer a simple, safe system with no flames or flues.
- You’re planning to stay in the home long enough to benefit from lower running costs.
When Gas or Other Options Might Be Better
- You already have gas connected and tariffs are competitive.
- You have limited electrical capacity and can’t easily upgrade your switchboard.
- You want very fast recovery for large families with heavy hot water use.
Our Recommendation for Most Canberra Homes
For many Canberra homes, a high‑efficiency electric option (like a heat pump) gives the best balance of comfort and long‑term running costs, especially when paired with solar. A modern, well‑sized electric storage tank can still be a smart choice on off‑peak tariffs if you’re on a tighter budget.
