Let’s talk about hot water – because comfort at home starts with a warm shower. If you’re scratching your head, wondering how to choose the best hot water system for your place, you’re in the right spot. Australia has many options, and we’re here to help you navigate the maze. So, grab a cuppa, kick back, and let’s figure out which hot water buddy suits you best. Read on!
Types of Hot Water Systems
Storage systems
These traditional hot water systems store a specific amount of hot water in a tank. They are reliable and suitable for households with consistent hot water demand. However, remember that they can be less energy-efficient as they constantly maintain the water temperature, even when you’re not using them.
Instantaneous (tankless) systems
Tankless systems heat water on-demand, providing hot water when needed. They are more energy-efficient than storage systems since they only operate when you open a hot water tap. Tankless systems are perfect for homes with fluctuating hot water demand or limited space.
Solar boosted systems
These water heaters combine solar panels with electric or gas systems. They use solar energy to preheat the water, reducing the workload on the backup system. Solar-boosted systems are eco-friendly and can lead to significant energy savings.
Consider the Climate
Australia’s diverse climate zones impact the efficiency and type of hot water system that suits your home. The country’s regions can be broadly divided into four climate zones:
Tropical and subtropical
The climate is warm and humid in northern parts of Australia, like Queensland and Western Australia. Here, solar hot water systems are highly efficient and cost-effective. These systems harness the abundant sunlight to heat water, reducing energy bills and carbon footprint.
Temperate
Most of Australia’s populated regions, including Sydney, Melbourne, and Adelaide, fall into the temperate zone. Heat pump hot water systems and gas storage systems work well in these areas. Heat pumps pull available heat from the air to warm water, while gas systems are reliable and work efficiently in milder climates.
Arid
Regions such as Alice Springs and parts of Western Australia experience arid conditions. Solar hot water systems and gas continuous flow systems are excellent choices here. Solar systems make the most of the sunny weather, and gas continuous flow units heat water on demand, providing an endless hot water supply.
Alpine
If you live in the alpine areas of Australia, like the Snowy Mountains, consider a gas storage system or an electric-boosted solar system. These systems can withstand colder temperatures and provide hot water when needed.
Energy Efficiency Matters
With rising energy fees and environmental concerns, energy efficiency should be prioritised when selecting a hot water system. In Australia, the Energy Rating label is your best friend. Look for the highest star rating and check the annual energy consumption in kilowatt-hours (kWh) to gauge efficiency.
Solar hot water systems
Solar hot water systems are among the most energy-efficient options. They produce zero emissions and can significantly reduce your energy bills. Ensure your solar system has a high star rating and is eligible for government incentives and rebates.
Heat pump systems
Heat pump systems are efficient, using the warmth in the air to heat water. Look for models with a good star rating, and consider the installation location, as they require ventilation.
Gas hot water systems
Gas systems are known for their quick recovery time and energy efficiency. Consider a 5-star rated gas system, and remember that natural gas is a greener option than LPG.
Electric hot water systems
Electric systems are typically less energy-efficient than the alternatives, but if you must go electric, consider a heat pump or electric-boosted solar system to improve efficiency.
Capacity and Usage
Your household size and your hot water usage patterns play a pivotal role in gauging the capacity of your hot water system. An undersized system won’t meet your needs, while an oversized one may lead to unnecessary energy costs.
Family size
For a small household of one to two people, a 50-80-litre system may suffice. A family of three to four will likely need a 125-160-litre unit, while larger families of five or more may require a system of 250-litres or more capacity.
Usage patterns
Consider your family’s usage patterns. A continuous flow (tankless) system might be the best choice if you have multiple bathrooms and appliances requiring hot water simultaneously. They heat water on demand, ensuring a constant supply.
Budget and Operating Costs
Your budget is a significant decision-making factor. While you may have to invest more upfront for an energy-efficient system, the long-term savings on energy fees can make it a wise financial decision.
Upfront costs
Solar and heat pump systems tend to have higher upfront costs due to installation requirements. Gas and electric storage systems are generally more budget-friendly initially.
Operating costs
Consider the ongoing operating costs, including energy bills and maintenance. Solar systems and heat pumps typically have lower operating costs over time, making them cost-effective choices.
Installation and Space
The installation process and available space in your home also influence your hot water system choice.
Installation
Solar and heat pump hot water heaters require specific installation considerations, like adequate roof space and ventilation. Gas and electric storage systems are usually easier to install.
Space
Check if your chosen system fits within the available space in your home. It’s essential to ensure proper ventilation and clearances for safe operation.
Maintenance and Lifespan
Routine maintenance is critical to prolonging the lifespan and efficiency of your hot water system. Consider the care and maintenance requirements and costs associated with your chosen system.
Solar and heat pump hot water systems
Solar and heat pump hot water systems require minimal maintenance but should be inspected periodically for optimal performance.
Gas and electric systems
Gas and electric systems may need more frequent care, including checking for leaks and replacing heating elements.
Government Incentives and Rebates
Take advantage of government incentives and rebates to reduce the cost of your hot water system. In Australia, various schemes exist to encourage the adoption of energy-efficient hot water systems. Check with your local government and utility providers for available incentives.
Warranty and Reliability
Ensure your chosen hot water system has a warranty that provides adequate coverage. A reliable brand with an excellent customer track record can give you peace of mind, knowing you’ll have access to support and spare parts if needed.
Environmental Impact
