Having a reliable hot water system is essential for any home, as it provides the comfort and convenience of having hot water at all times. However, choosing the right size hot water system for your home can be a daunting task, and making the wrong decision can lead to inefficiency, higher energy costs, and even system failure.
Importance of hot water systems
Hot water systems play a crucial role in our daily lives, providing hot water for showers and baths and washing dishes and clothes. They also help to improve our overall quality of life by allowing us to maintain a clean and hygienic environment.
The importance of hot water systems can be further highlighted by looking at the various ways they are used in our homes. For example, hot water is essential for cleaning, as it helps to remove dirt and bacteria from surfaces, clothes, and dishes. It is also important for personal hygiene, as hot water is necessary for showers and baths. In addition, hot water systems also play an important role in energy efficiency, as they use less energy to heat water than other methods, such as electric water heaters.
Factors to consider when choosing the right size
When choosing the right size hot water system for your home, there are several factors that you should consider. These include the number of people in your household, the type of showerheads and faucets you have, your usage patterns, and the climate and temperature of your area.
Choosing the right size hot water system for your home requires careful consideration and understanding these factors will help you make an informed decision and ensure that you have the perfect hot water system for your home.
Assessing your hot water needs
Once you understand the importance of hot water systems and the factors to consider when choosing the right size, the next step is to assess your hot water needs. This includes evaluating the number of people in your household, the type of showerheads and faucets you have, your usage patterns, and the climate and temperature of your area.
Number of people in the household
The number of people in your household is one of the most important factors to consider when assessing your hot water needs. The more people you have in your home, the more hot water you need. A general rule of thumb is to have 4 litres of hot water per person per day.
Your actual hot water needs may vary depending on your specific usage patterns and the type of showerheads and faucets you have. For example, a household of four people would require a hot water system with a capacity of at least 16 litres per day. However, it is important to note that this is a general guideline and individual circumstance may vary.
Type of showerheads and faucets
The type of showerheads and faucets in your home can also affect your hot water needs. Low-flow showerheads and faucets use less water than standard ones, so you will need less hot water if you have low-flow fixtures. On the other hand, if you have standard fixtures, you will need more hot water.
Usage patterns
Your usage patterns can also affect your hot water needs. If you use hot water mainly in the morning, you will need more hot water than if you use it mainly in the evening. Similarly, if you have a large family that takes several showers and baths in the morning, you will need more hot water than a smaller family that mainly uses hot water in the evening.
Climate and temperature
Climate and temperature are also important factors to consider when assessing your hot water needs. In colder climates, you will need more hot water to keep your home warm, while in warmer climates, you may not need as much.
Types of hot water systems
Once you have assessed your hot water needs, the next step is to familiarise yourself with the different types of hot water systems available on the market. This will help you understand each type’s pros and cons and determine which is best suited for your home.
Tankless water heaters
Tankless water heaters, also known as demand water heaters, heat water on demand rather than storing it in a tank. This means that they only heat water when you need it, which can help to save energy and reduce costs. Tankless water heaters are also smaller and more compact than traditional storage tank water heaters, making them a good choice for homes with limited space.
Conventional storage tank water heaters
Conventional storage tank water heaters are the most common type of hot water system and are typically less expensive than tankless water heaters. They store hot water in a tank and use a heating element to keep it hot. These systems are typically more efficient than electric water heaters but have a limited hot water supply and are not as energy efficient as tankless water heaters.
Heat pump water heaters
Heat pump water heaters use electricity to transfer heat from the air or ground to heat water. These systems are typically more energy efficient than conventional storage tank water heaters. Still, they require a separate space for the heat pump unit and can be more expensive to install.
Solar water heaters
Solar water heaters use energy from the sun to heat water. These systems are typically the most energy-efficient and cost-effective option. Still, they can be expensive to install and may not be suitable for homes in climates with limited sunlight.
Understanding the different types of hot water systems available on the market is important in choosing the right size for your home. Each type has its pros and cons, and it is important to consider which fits your specific needs and budget best.
Calculating the right size
Once you have familiarised yourself with the different types of hot water systems, the next step is to calculate the right size for your home. This includes measuring the flow rate, determining the first hour rating (FHR), understanding Minimum Energy Performance (MEPs), and sizing based on the number of people in the household and usage patterns.
Measuring flow rate
Measuring the flow rate of your hot water system is an important step in determining the right size. The flow rate is the amount of hot water used per minute, measured in litres per minute (LPM). The flow rate can be measured using a flow meter, which can be purchased at most hardware stores.
Determining the First Hour Rating (FHR)
The First Hour Rating (FHR) measures how much hot water a hot water system can produce in one hour. It is typically measured in litres, which is a good indicator of the overall capacity of the hot water system. The FHR can be found on the Energy Guide label of the hot water system, and it is an important factor to consider when choosing the right size.
Understanding Minimum Energy Performance (MEPs)
Electric, gas storage, and gas instantaneous water heaters must comply with the Minimum Energy Performance Standards (MEPS) outlined in the GEMS regulations according to the Australian government regulations. Solar water heaters, heat pump water heaters, and electric instantaneous water heaters are not subject to energy efficiency performance requirements. At a glance, the more energy stars on the appliance or MEPs, the more energy efficient is it in providing hot water for your family.
Sizing based on the number of people in the household and usage patterns
Sizing your hot water system based on the number of people in the household and usage patterns is an important step in determining the right size. As previously mentioned, a household of four people would require a hot water system with a capacity of at least 16 litres per day. Usage patterns, such as when you use hot water, can affect your hot water needs.
Professional assistance
While choosing the right size hot water system for your home is possible by following the steps outlined in this guide, it is often helpful to consult with a professional plumber or HVAC technician. These professionals have the expertise and experience to help you make an informed decision and ensure that your hot water system is properly sized and installed.
