Should You Update Your Water Heater to a Tankless Model?

Living in Australia means being aware of the ecosystem that’s all around us, visible in the beaches, the parks, and the sprawling vistas of the great outdoors. But according to the Greendex country report, which measures the environmental sustainability and behaviors of ordinary citizens in 18 countries, Australia ranks rather low, coming in at thirteenth. This means that Australians are less likely to save energy—especially at home, which is reflected in Australians use of water heating.

For an average Australian home, water heating is the second largest factor in household energy usage after space heating and cooling, and the largest source of greenhouse gas emissions in general. This makes it all the more important for Australians to consider switching to a tankless water heater, which can reduce energy use as compared to a gas heater. Plus, buying a tankless water heater has a range of other benefits for your home, too, that can outweigh installing or keeping a traditional model.

Pros and Cons of Going Tankless

In addition to the energy savings, tankless water heaters can save homeowners money on electricity bills. Depending on the model, you may be able to save up to 150 AUD per year by switching out your gas heater. Tankless water heaters also feature compact designs, minimising the amount of space they take up and making them moveable to non-traditional locations in the home.

While these benefits may all seem to outweigh traditional heaters, the primary downside to upgrading to tankless is just that—it’s an upgrade, and upgrades cost money. In some cases, tankless water heaters can cost more than three times what a traditional gas heater is priced. And, your home may not be able to support a tankless heater if your home has electric-only utilities, meaning you may have to add the cost of hiring an electrician to update your systems first.

Practical Considerations to Keep in Mind

Before making the decision to switch to a tankless water heater for your home, there are several practical considerations. As mentioned already, first you will want to make sure your home can support a tankless heater. Then, you will want to know your home’s hot water requirements—will your tankless heater need to heat a single bathroom, or the entire home? This will affect the placement and the capacity of the tank you purchase.

You will also want to consider the life expectancy on the tank. On average, tankless water heaters provide 20 years of service—twice the lifespan of a traditional water heater. If you are looking for a long-term utility investment, a tankless heater may be a wise decision.

Now that you know the pros and cons of tankless water heaters, you can make the move to switch to tankless from your traditional heater after taking into account all of the practical considerations.
