How Do I Determine My Household’s Hot Water Demand?

When trying to determine your household’s demand, you need to consider the amount of people living within the property. As a general rule we consider:

1. For a Family of Four: Typically, a family of four in Australia needs a hot water system that can supply approximately 125 to 360 litres daily. The exact requirement will depend on factors such as the type of heater / system and water usage patterns.

2. For a Household of Three: The average Australian uses about 76 litres of hot water daily. Therefore, a household of three would consume around 228 litres
   per day. This can vary based on specific usage factors.

Other factors to consider when choosing the best hot water system

• Location of the hot water system (eg. inside, outside or on the roof etc) What are the installation cost, running cost and green credentials?
• What are the installation cost, running cost and green credentials?
• What type of hot water system (eg. gas, electric, instant etc)

Selecting the right hot water system size is crucial for ensuring efficient and comfortable hot water supply in your home. This comprehensive guide will help you understand the key factors to consider when making your decision.

System Type and Energy Source

The type of hot water system and its energy source significantly impact its size and efficiency. Common tank-based systems include gas, electric, solar, and heat pump options. Each has its own advantages and drawbacks in terms of initial cost, energy efficiency, and environmental impact.

Temperature Rise

Temperature rise, the difference between the desired hot water temperature and the incoming cold water temperature, is a critical factor. A higher temperature rise generally requires a larger system to meet your hot water needs.

Climate

Your region’s climate plays a crucial role in determining system size. Colder climates may necessitate larger systems due to increased heat demand. Conversely, warmer climates with ample sunlight are ideal for solar water heaters. Additionally, consider seasonal variations in hot water usage, especially during peak times.
Budget

While initial costs vary, energy-efficient systems can often offset higher upfront prices with long-term savings. Explore government incentives or rebates to reduce the financial burden.

Building Type

The size and occupancy of your home influences hot water demand. Larger homes or commercial properties require more substantial systems to accommodate multiple occupants and fixtures.

Plumbing Infrastructure

Older or inefficient plumbing can hinder water flow, necessitating a larger system. Regular maintenance, including leak repairs and flushing, can improve efficiency and reduce the required system size.

Future Expansion
Consider your home’s potential growth. Planning for future additions or increased occupancy can help you avoid costly upgrades later.
