Both options offer their unique benefits, but how do you know which one is right for you? In this guide, we’ll compare the pros and cons of both gas and electric systems, analyze their running costs, and help you decide which is the best choice for your needs.

Instant hot water systems are a fantastic solution for those looking for convenience, energy efficiency, and space-saving benefits. But with so many choices available, it’s essential to weigh your options carefully. Let’s dive in and explore gas vs electric instant hot water systems in detail.

What are Instant Hot Water Systems?

Instant hot water systems, also known as continuous flow or instantaneous water heaters, provide hot water on-demand without the need for a storage tank. This makes them a compact and energy-efficient option for modern homes and businesses. With an instant system, you can enjoy hot water whenever you need it, with no waiting time.

Why Choose Instant Hot Water Systems?

Instant hot water systems are gaining popularity for their:

• Energy efficiency: Only heats water as it’s needed, saving energy compared to traditional storage systems.

• Compact design: No bulky tank taking up space.

• Endless hot water: Never run out of hot water, as the system heats it as it flows through.

But the choice between gas and electric models is a significant factor in determining the system’s overall performance, installation, and running costs.

Gas vs Electric Instant Hot Water: Which One is More Efficient?

Electric Instant Hot Water Systems

Electric systems are an increasingly popular choice in Australia, particularly in smaller homes and businesses. These systems are ideal for locations with limited space or where gas infrastructure is unavailable.

Running Costs

Electric instant systems have lower annual running costs compared to traditional storage electric heaters. Here’s a breakdown of costs:

• For a small household (1-2 people): Around $585 per year for electric instant systems.

• For a medium-sized household (4 people): Around $970 per year.

Electric systems are a great option for smaller applications or places with minimal hot water demand, but they can become more expensive as the demand grows.

Pros of Electric Instant Systems

• Easy Installation: Electric systems are typically easier and cheaper to install.

• No Ventilation Required: Unlike gas heaters, electric systems don’t need ventilation.

• Compact Design: Can be installed in tight spaces near sinks or taps, reducing lag time when you need hot water.

• Can Work with Solar: Ideal for homes with solar hot water systems as a booster without needing additional power sources.

Cons of Electric Instant Systems

• Higher Running Costs for Large Households: As demand increases, so does the cost.

• Limited Flow Rate: Electric systems may struggle with higher water demand in larger homes.

Gas Instant Hot Water Systems

Gas instant systems have been around for many years and are often the preferred choice for larger homes or high-demand applications. They are known for their superior energy efficiency and ability to handle higher flow rates.

Running Costs

• For a small household (1-2 people): Gas instant costs around $420 per year.

• For a larger household (4 people): Gas instant can save up to $750 annually compared to electric systems, with running costs around $365 per year for natural gas.

Gas systems can be the most cost-effective choice for homes with high hot water demands.

Pros of Gas Instant Systems

• Lower Running Costs: More economical than electric for larger households.

• Fewer Greenhouse Gases: Gas systems produce up to 75% fewer emissions compared to electric storage heaters.

• Higher Flow Rate: Ideal for large homes or businesses that need more hot water at once.

• Space-Saving: Compact design frees up space in your home or garden.

• Longer Lifespan: Gas systems tend to last longer with fewer maintenance requirements.

Cons of Gas Instant Systems

• Ventilation Required: Must be installed with proper ventilation to avoid dangerous by-products like carbon monoxide.

• Installation Complexity: Gas systems may require more complicated installation, including flueing and additional safety measures.
