The right size depends on how many people live in the home and when you all shower.
When your hot water dies, it is never convenient. Cold showers before work, a laundry that stops, and a rushed decision to replace whatever was there before. That last part is the costly mistake. The hot water system you choose runs for ten to fifteen years, and the gap between a cheap-to-buy unit and a cheap-to-run one adds up over that life. We supply hot water systems to Perth, WA homes and trades, and this guide covers the four types, how to size one, and the brands worth fitting.
The four types of hot water system
Electric
- Heats water with an element, stored in a tank
- Lowest upfront cost, simple replacement
The cheapest to buy and the simplest like-for-like swap. Running cost is higher than gas or heat pump, so they suit smaller households or budgets that need the lowest upfront spend.
Gas
- Storage tank or continuous flow, heated by gas
- Low running cost, endless hot water on continuous flow
Available as storage or continuous flow (instantaneous). Continuous flow only heats water as you use it, so you never run out and you are not paying to keep a tank warm. Running costs are typically lower than electric.
Heat pump
- Pulls heat from the air, like a reverse fridge
- Lowest running cost, rebate-eligible
Uses a small amount of electricity to move heat from the air into the water, rather than generating it directly. That makes it far more efficient than standard electric, and heat pumps are commonly eligible for rebates, which narrows the upfront gap.
Solar
- Roof collectors plus a boosted tank
- Lowest running cost long term, rebate-eligible
Roof-mounted collectors do most of the heating, with a gas or electric booster for cloudy stretches. The highest efficiency over the long run, and rebate-eligible.

How to size your hot water system
The right size comes down to how many people live in the home and whether you all use hot water at the same time. As a general guide:
- 1 to 2 people | Smaller tank | Lower flow rate model
- 3 to 4 people | Mid-size tank | Mid flow rate model
- 5 or more people | Larger tank | Higher flow rate model
A few rules of thumb:
When in doubt, size up one step. Running out of hot water is the complaint we hear most, and it is almost always an undersized unit.
Frequently asked questions
Which hot water system is cheapest to run?
Heat pump and solar systems usually have the lowest running costs, followed by gas, with standard electric the most expensive to run. Electric is the cheapest to buy, which is the trade-off.
Are there rebates for hot water systems?
Heat pump and solar systems are commonly eligible for government rebates and incentives, which can significantly change the real cost compared with electric or gas. Rebate programs and amounts change over time, so check what currently applies before you decide.
What size hot water system do I need?
It depends on household size and when you all use hot water. As a guide, smaller households suit smaller tanks or lower flow rates, and larger households or homes with overlapping shower times need a bigger tank or a higher flow rate. If you are unsure, size up.
What is the difference between storage and continuous flow?
A storage system heats a tank of water and keeps it hot, ready to use. A continuous flow (instantaneous) system heats water only as you draw it, so it never runs out and does not pay to keep a tank warm.
