Having a hot water system is one of those household essentials that we all take for granted. However, choosing a hot water system is an important decision that affects your energy costs and the environmental impact of your home or business. The choice you make depends on several factors, including your lifestyle, the layout of your house or workplace, your budget, and your preferred level of environmental performance.
Fortunately, you can choose a system that meets all of your needs and still be a good steward of the environment and your energy costs. The best way to do this is to look into the different types of systems and decide what your priorities are. Then you can choose a system that will meet your expectations all year round.
The first thing to consider when choosing a new hot water system is the heating method. This is where you need to decide whether you want to go with a storage tank design or a continuous flow (‘instantaneous’) system.
Electric storage hot water systems heat the cold water in their tanks with one or two elements and hold it until you turn on a hot tap. This means you can have a large volume of hot water on demand, but it also means the tank will lose heat energy when there is no demand. Continuous flow systems only heat the water as it is being used and don’t suffer the same loss of energy.
Solar, heat pump and gas systems all produce less energy-intensive hot water. However, they are not as cost-effective as electric storage systems and may require a significant upfront investment. The good news is that they can often be recouped over time with government rebates and incentives.
Choosing a hot water system that is energy efficient can save you money and reduce your greenhouse gas emissions. In Australia, all hot water systems are required to have a Minimum Energy Performance Standard (MEPS). The MEPS label shows you how energy-efficient your appliance is and how much it will cost you over its lifetime. You can check the MEPS for your chosen system by visiting the Australian Hot Water Federation website.
