Gas Hot Water - Reliable and Cost-Effective
Gas hot water systems have been a Perth staple for decades. With natural gas widely available and generally cheaper than electricity, gas systems offer reliable hot water at reasonable running costs.

Storage vs Instantaneous Gas
Gas Storage Systems
- Keeps a tank of water constantly hot
- Simple and reliable technology
- Good for consistent usage patterns
- Lower upfront cost
- Takes up more space
Gas Instantaneous (Continuous Flow)
- Heats water only when needed
- Never runs out of hot water
- More energy efficient
- Compact wall-mounted design
- Higher upfront cost but longer lifespan
