Gas vs Electric Hot Water Systems

June 30, 20262 min read

With winter coming along, there’s nothing better than stepping into a hot shower on a freezing morning, which is why choosing the right hot water system matters. Whether you’re replacing an older unit or installing a new system, one of the biggest decisions is choosing between gas and electric hot water.

At Wanaka Plumbing & Gas, we help homeowners throughout Wanaka choose reliable and energy-efficient hot water systems that suit their household needs and budget.

Comparing the Cost of Gas and Electric Hot Water Systems

When comparing gas and electric systems, it’s important to look at both installation costs and long-term running expenses.

Electric hot water systems are usually cheaper to install because they connect directly to your existing electrical supply. Gas systems, however, require installation by a qualified gas fitter and may need additional gas connections depending on your property setup.

While gas systems often cost more upfront, they are typically cheaper to run over time. For households with higher hot water usage, gas hot water can provide noticeable savings on energy bills compared to electric systems.

Gas Storage Hot Water Systems

Gas storage systems are one of the most common hot water options for family homes.

These systems store heated water inside an insulated tank, ready for use whenever needed. A gas burner located beneath the tank heats the water and maintains a consistent temperature throughout the day.

Because hot water is stored in advance, gas storage systems work well for larger households that regularly use multiple showers, taps, or appliances at the same time.

Continuous Flow Gas Hot Water Systems

Continuous flow systems, also known as instantaneous hot water systems, heat water only when you need it.

Unlike storage systems, they don’t keep hot water sitting in a tank. Instead, water passes through a heat exchanger where gas burners heat it instantly as it flows through the unit.

One of the biggest benefits of continuous flow systems is energy efficiency. Since water is only heated when required, there’s no heat loss from stored water, which can help reduce energy costs.

These systems are also compact and ideal for homes looking to save space.

Choosing the Right System for Your Home

The best hot water system depends on several factors, including:

  • Household size

  • Daily hot water usage

  • Energy efficiency goals

  • Budget

  • Available utilities at your property

A professional plumber or gas fitter can help you compare options and recommend the right solution for your home.
