But with so many different types of hot water systems on the market, it can be tough to know which one is the best fit for your family. WPG Plumbing can guide you through the process of choosing the perfect hot water system for your large Werribee home.

What’s a “large family” in Werribee?

Let’s first define what could be considered a “large family” in Werribee. While there’s no hard and fast rule, a large family typically includes:

  • More than four people living in the home
  • Multiple bathrooms
  • High demand for hot water, especially during peak times like mornings and evenings

Understanding Your Family’s Needs

It’s essential to understand your family’s specific needs. Here are some questions to consider:

  • Daily hot water usage: How often do you shower, do laundry, and wash dishes? Are there any other tasks that require hot water, such as pool heating or spa maintenance?
  • Peak demand times: When is your family most likely to use hot water? Are there any specific times of day when demand is particularly high, such as mornings and evenings?
  • Number of bathrooms: How many bathrooms does your home have? The more bathrooms you have, the greater the demand for hot water will be.
  • Laundry and dishwasher requirements: How often do you do laundry and wash dishes? These appliances can consume a significant amount of hot water.
  • Outdoor hot water needs: Do you have a pool or spa that requires heating? If so, this will increase your overall hot water demand.

Factors to Consider for Large Families

There are several key factors to keep in mind:

  • Capacity: The system should have the capacity to meet your family’s peak demand for hot water. This is especially important during busy times, such as mornings and evenings.
  • Energy efficiency: Look for a system that is energy efficient to minimize your energy consumption and costs. This is particularly important for large families who use a lot of hot water.
  • Reliability: A reliable hot water system is essential to avoid disruptions to your daily routine. Consider the system’s track record for reliability and the availability of spare parts and repairs.
  • Cost: The initial purchase and installation cost of a hot water system can vary significantly. It’s important to consider not only the upfront costs, but also the ongoing operational costs, such as energy consumption and maintenance.
  • Environmental impact: If you’re concerned about the environment, look for a hot water system that has a low carbon footprint. Solar thermal systems and heat pump hot water systems are good options for those who want to reduce their environmental impact.

Types of Hot Water Systems

There are two main types of hot water systems: storage tank systems and continuous flow systems.

Storage Tank Systems

Storage tank systems heat and store water in a large tank. When you need hot water, it’s drawn from the tank.

  • Traditional electric storage tank: This is the most common type of hot water system in Australia. It uses electricity to heat water in a tank. The tank is typically insulated to help retain heat.
  • Gas storage tank: Similar to an electric storage tank, but it uses gas to heat the water. Gas storage tanks are often more energy efficient than electric ones, especially in areas with high electricity costs.
  • Solar thermal storage tank: This system uses solar panels to heat water. The heated water is then stored in a tank for use later. Solar thermal systems can be a great way to reduce your energy bills, but they require a significant upfront investment.

Continuous Flow Systems

Continuous flow systems heat water on demand, as you need it. This means there’s no need for a storage tank.

  • Gas instantaneous heaters: These heaters use gas to heat water as it flows through them. They are highly efficient and provide a constant supply of hot water.
  • Electric instantaneous heaters: Similar to gas instantaneous heaters, but they use electricity to heat the water. Electric instantaneous heaters are generally less efficient than gas ones, but they are a good option if you don’t have access to gas.
  • Heat pump hot water systems: These systems use a heat pump to extract heat from the air and transfer it to water. They are highly energy efficient, but they can be more expensive to install than traditional systems.

Storage Tank Systems – A Deep Dive

Storage tank systems are a popular choice for large families because they can store a significant amount of hot water. However, they also have some drawbacks.

Electric Storage Tank Systems

Pros:

  • Affordable: Electric storage tanks are generally the most affordable option upfront.
  • Reliable: They have a proven track record of reliability.
  • Easy to install: Installation is relatively straightforward.

Cons:

  • Less energy efficient: Electric storage tanks can be less energy efficient than other options, especially if they are not well-insulated.
  • Potential for standby losses: Even when not in use, electric storage tanks can lose heat, which can increase energy consumption.

Gas Storage Tank Systems

Pros:

  • More energy efficient: Gas storage tanks are often more energy efficient than electric ones, especially in areas with high electricity costs.
  • Faster heating: Gas heaters can heat water more quickly than electric ones.

Cons:

  • Higher upfront costs: Gas storage tanks can be more expensive to install than electric ones.
  • Requires gas connection: You’ll need to have a gas connection to your home.

Solar Thermal Storage Tank Systems

Solar thermal systems use solar panels to heat water. The heated water is then stored in a tank for use later.

  • Types: There are two main types of solar thermal collectors: evacuated tube collectors and flat plate collectors. Evacuated tube collectors are generally more efficient, but they can also be more expensive.
  • Efficiency and payback periods: The efficiency of a solar thermal system depends on factors such as the size of the system, the location of the solar panels, and the climate. The payback period for a solar thermal system can vary, but it’s typically several years.
  • Storage tank capacity requirements: The size of the storage tank for a solar thermal system will depend on your family’s hot water needs and the amount of sunlight your home receives.

Hybrid Systems

Hybrid systems combine solar thermal technology with a traditional gas or electric storage tank. This can help to reduce your reliance on fossil fuels and lower your energy bills.

Is a storage tank system right for your family?

Storage tank systems can be a good choice for large families, especially if you have a limited budget. However, it’s important to consider factors such as energy efficiency, reliability, and environmental impact. If you’re looking for a more energy-efficient option, you may want to consider a continuous flow system or a hybrid system.

Continuous Flow Systems – A Closer Look
