Gas Hot Water Systems in Canberra
Gas hot water is a popular choice for Canberra homes that want fast, reliable hot water and strong performance for busy families. When it’s sized and installed correctly, a gas system can deliver consistent hot water, even at peak times, while keeping running costs under control.
1. Gas Storage Hot Water (Tank Systems)
These systems store a set volume of hot water in an insulated tank and keep it hot using a gas burner.
How it works
- Cold water enters the tank.
- A gas burner heats the water and maintains a set temperature.
- Hot water is drawn from the top of the tank when you turn on a tap.
Pros
- Strong, reliable hot water supply for families.
- Faster recovery than many electric storage systems.
- Works well where gas is already connected.
- Simple, proven technology with easy servicing.
Cons
- Some heat loss from the tank over time.
- If the tank is undersized, you can still “run out” of hot water.
- Requires a gas connection and proper flueing.
- Older units can be less efficient than modern options.
Best for
- Medium to large households with steady hot water use.
- Homes that already have gas connected.
- Replacements where a gas storage tank is already installed.
2. Gas Continuous Flow (Instantaneous)
Gas continuous flow systems heat water on demand as it passes through the unit, rather than storing it in a tank.
How it works
- Water flows through a compact wall‑mounted unit.
- A gas burner fires only when you turn on a hot tap.
- Water is heated as it passes through, so there’s no storage tank.
Pros
- “Endless” hot water for as long as the unit is running.
- No standing heat loss from a tank.
- Compact size, ideal for tight outdoor spaces.
- Only uses gas when you actually use hot water.
Cons
- Flow rate is limited by the size of the unit – very high demand may need a larger model.
- Water temperature can vary slightly if multiple taps are used at once.
- Requires correct gas sizing and flueing.
Best for
- Homes with limited space for a tank.
- Busy households that want continuous hot water.
- Replacements where an old continuous flow unit is being upgraded.
Gas vs Electric vs High‑Efficiency – Cost & Performance
Upfront Costs (Typical Pattern)
- Standard electric storage: usually lowest upfront.
- Gas storage / gas continuous flow: mid‑range upfront cost.
- Heat pump / high‑efficiency systems: highest upfront, but lower running costs.
Running Costs (General Guide)
- Standard electric storage on standard tariff: often the most expensive to run.
- Gas storage / gas continuous flow: moderate running costs, especially where gas tariffs are reasonable.
- Heat pump electric: usually the lowest running costs, especially when paired with solar.
When Gas Hot Water Makes Sense
- You already have gas connected to the property.
- You want strong performance for families and high hot water demand.
- You prefer a compact, outdoor unit (continuous flow) or a robust tank system.
When You Might Consider Other Options
- You don’t have gas connected and don’t want the cost of adding it.
- You have solar panels and want to maximise electric self‑consumption.
- You’re focused on the lowest possible long‑term running costs (often heat pump).
