Essential Comfort Down Under: The Importance of Hot Water Services in Australia

Nov 15, 2023

In Australia, hot water is a given. We turn on the tap, and it’s there. But have you ever thought about the mechanics behind it? It’s not always sunny in “Sunny” Australia. On a cold Winter’s night, there’s nothing better than a hot shower or bath to finish the day. Hot water contributes to our comfort, hygiene, and certain health practices and without hot water systems, we’d have no hot water at all.

While cold water can fulfil basic cleaning needs, hot water often makes the process more pleasant and effective. Hot water is frequently used for activities that promote health, such as washing hands to remove germs more effectively. It is also commonly used in the preparation of hot beverages and meals, which keeps us healthy and happy. In colder climates, access to hot water becomes more critical for maintaining body temperature and preventing conditions like hypothermia. Hot water is also essential for creating a warm indoor environment in colder weather.

While hot water is not a fundamental requirement for survival, its availability can significantly enhance the quality of life and contribute to overall well-being. In modern societies, access to hot water is considered a standard amenity in homes, contributing to daily comfort and hygiene practices. In Australia our hot water is accessed through outside hot water systems, either from gas or electric tanks or through solar panels.

The Three Types of Hot Water Systems In Australia

Hot water systems come in three primary variants: gas, electric and solar. Gas systems typically rely on natural gas or LPG to heat water efficiently, while electric systems use electricity to power heating elements, providing households with flexibility in choosing the most suitable option based on energy sources and preferences.

Gas Hot Water Systems:

Gas Storage Water Heaters:

  • Operation: A gas burner is located at the bottom of a storage tank. When the thermostat detects a drop in water temperature, it triggers the burner to heat the water until it reaches the desired temperature.
  • Capacity: These systems come in various sizes, with larger tanks suitable for households with higher hot water demands.

Gas Continuous Flow (Tankless) Water Heaters:

  • Operation: When a hot water tap is turned on, cold water travels through a heat exchanger where a gas burner heats the water on demand. The hot water is then delivered to the tap.
  • Energy Efficiency: Since they only operate when hot water is needed, they can be more energy-efficient than storage heaters.

Electric Hot Water Systems:

Electric Storage Water Heaters:

  • Operation: Electric elements, typically located at the bottom and sometimes the sides of the tank, heat the water. A thermostat regulates the temperature, and the hot water is stored until it’s needed.
  • Recovery Time: The time it takes to heat a new batch of water can be longer than gas systems, especially if the demand is high.

Electric Continuous Flow (Tankless) Water Heaters:

  • Operation: Similar to gas tankless systems, electric tankless heaters heat water instantly as it flows through the unit. They use electric heating elements to achieve this.
  • Compact Design: These units are often more compact than storage heaters, saving space.

Differences Between Gas and Electric Hot Water Systems:

Energy Source:

  • Gas Systems: Use natural gas or LPG. Natural gas is a fossil fuel, while LPG is a liquefied form of petroleum gas.
  • Electric Systems: Rely on electricity, which can come from various sources, including fossil fuels, nuclear, or renewable energy.

Efficiency:

  • Gas Systems: Tend to be more energy-efficient due to the direct use of combustion to heat water.
  • Electric Systems: May have slightly lower efficiency because of the conversion of electricity to heat.

Initial Cost and Installation:

  • Gas Systems: Initial costs can be higher due to the need for a gas connection and ventilation requirements for safety.
  • Electric Systems: Often have lower upfront costs and simpler installation, especially if the electrical infrastructure is already in place.

Running Costs:

  • Gas Systems: Generally have lower running costs, especially in areas where natural gas is competitively priced.
  • Electric Systems: May have higher ongoing costs, especially if electricity prices are high.

Environmental Impact:

  • Gas Systems: Produce fewer greenhouse gas emissions during operation, making them a more environmentally friendly option if the gas source is relatively clean.
  • Electric Systems: The environmental impact depends on the energy mix of the electricity grid. If the electricity comes from renewable sources, the impact is lower.

Solar Hot Water Systems

Solar hot water services differ from gas and electric systems by harnessing sunlight to directly heat water, offering a renewable and environmentally friendly alternative.

Solar Storage Water Heaters:

Operation

  • Solar collectors absorb sunlight and transfer the heat to a fluid, which then circulates through a system to warm the water in a storage tank. This heated water is ready for use when needed.

Capacity:

  • The capacity of solar storage systems varies, and larger collectors may be suitable for households with higher hot water demands.

Solar Continuous Flow (Tankless) Water Heaters:

Operation:

  • Similar to their gas and electric counterparts, solar tankless systems heat water on demand. Solar collectors capture sunlight, and a heat exchanger warms the water as it flows through the unit.

Energy Efficiency:

  • Solar systems harness renewable energy from the sun, making them highly energy-efficient and environmentally friendly.

Additional Considerations for Solar Hot Water Systems:

Supplemental Heating:

  • In periods of low sunlight or high demand, solar hot water systems may have backup mechanisms, such as electric or gas boosters, to ensure a continuous supply of hot water.

Installation and Costs:

  • While the initial costs for solar systems can be higher, various incentives and long-term savings on energy bills contribute to their cost-effectiveness over time.

Environmental Impact:

  • Solar hot water systems significantly reduce reliance on non-renewable energy sources, lowering carbon footprints and minimising environmental impact.

Choosing the right hot water system involves considering the specific features and benefits of each type, including gas, electric, and solar, based on individual preferences, energy efficiency goals, and local conditions.
