How to Choose the Best Hot Water System for Your Perth Home

Choosing the best hot water system for your Perth home can be a tricky decision. With Perth’s hot climate and abundant sunshine, solar hot water systems and heat pumps are some of the most efficient options available. However, there are many factors to consider before making a purchase, such as cost, space, usage, and the environmental impact. In this guide, we’ll break down everything you need to know to choose the right hot water system for your Perth home.

Cost of Hot Water Systems in Perth

Cost is often the deciding factor when choosing a hot water system in Perth. While some systems may have a lower upfront cost, they might not offer the best long-term savings. When considering a new hot water system, it’s essential to evaluate both the initial installation costs and the potential savings on energy bills.

For homes looking for a cost-effective hot water solution in Perth, replacing an old gas storage system or electric instantaneous system with a like-for-like model can seem the most affordable option. However, this might not provide the best long-term savings in terms of energy efficiency.

Types of Hot Water Systems and Their Costs

• Electric Instantaneous & Gas Storage Systems: These systems tend to have the lowest upfront costs but are less energy-efficient. Over time, this can result in higher energy bills.

• Gas Instantaneous Systems: A more efficient choice than traditional gas storage systems. Converting from a gas storage to a gas instantaneous system can save you money on energy bills.

• Heat Pumps: Heat pumps are available in various price ranges, from entry-level models like the Envirosun HP Plus to premium options like the Reclaim Energy heat pump. These systems can be eligible for STC rebates, reducing installation costs.

• Solar Hot Water Systems: Though installation costs have increased in recent years, solar hot water systems remain a great option for homes in Perth’s sunny climate. Like heat pumps, many solar hot water systems qualify for STC rebates.

How Hot Water Usage Affects Your Choice

Your hot water usage plays a major role in determining which system is right for your home. For homes with lower hot water demand, installing a solar hot water system or heat pump might not provide a strong return on investment due to their higher installation costs.

Low Usage Households:

For single-occupant homes or those with low hot water demand, electric instantaneous systems or gas instantaneous systems might be the best cost-effective hot water solutions. Since these systems don’t require significant changes to your existing plumbing, they can be installed at a lower cost. In such cases, replacing an old system with a like-for-like model may make the most sense.

High Usage Households:

For larger households or those with high hot water usage, systems like solar hot water or heat pumps can offer significant energy savings over the life of the system. These systems are designed to store larger amounts of hot water and are far more energy-efficient, which makes them ideal for high-demand homes. Additionally, instantaneous gas systems are perfect for homes that need an endless supply of hot water, as they heat water on-demand.

Space Considerations for Installing a Hot Water System

When choosing a hot water system, space is an important factor. Whether you live in a house or an apartment, it’s crucial to ensure there’s enough space for installation.

Apartments and Small Spaces:

If you're living in an apartment in Perth, your space may be limited to compact electric instantaneous or small electric storage systems. In these situations, a like-for-like replacement might be the best option, as it won’t require significant changes to your current plumbing setup.

Gas Hot Water Systems:

Gas systems often require specific installation conditions. They must be positioned a certain distance from walls, windows, and vents. If you're replacing an older gas hot water system, a gas instantaneous system might be easier to install with minimal changes. However, ensure that the system complies with local regulations and space restrictions.

Heat Pumps:

Heat pump systems generally require about 800mm of space for the unit itself, making them suitable for most homes. For split heat pumps, the tank and heat pump unit are separate, which allows for more flexibility in installation. The tank can be placed on the ground, while the heat pump can be installed on the roof or another convenient location.

Solar Hot Water Systems:

Solar hot water systems require substantial roof space for installation. A split system will need at least 2.2m² of roof space, while larger systems may require up to 2.5m² by 3mH of space. Be sure to check that your roof can handle the weight and size of the system.

Environmental Impact of Hot Water Systems

In today’s world, environmental impact is an essential factor when choosing a hot water system. With Perth’s sunny climate, solar hot water systems and heat pumps are two of the most environmentally friendly options available.

Heat Pumps & Solar Hot Water:

When paired with a solar PV system, heat pumps provide almost free hot water throughout the year by using excess energy produced by your solar panels. This combination is not only cost-effective but also reduces your carbon footprint significantly. Heat pumps are manufactured with low-impact refrigerants, ensuring that their environmental impact is minimal.

Similarly, solar hot water systems use solar energy to heat water, making them one of the most environmentally friendly options. Most solar hot water systems in Perth provide enough hot water for the entire year, with only occasional use of backup boosters.

Electric Storage Systems:

Electric storage systems, while less efficient, can still have a reduced environmental impact when paired with a solar PV system. By programming your electric hot water system to run during the day when the solar panels are generating power, you can significantly lower the system’s environmental footprint.

Gas Systems:

Gas hot water systems generally have a higher environmental impact due to their reliance on fossil fuels. However, newer, energy-efficient gas systems (like 6-star gas instantaneous models) are more efficient than older versions and can help reduce carbon emissions compared to outdated, less efficient models.

Conclusion

Choosing the best hot water system for your Perth home requires careful consideration of factors such as cost, usage, space, and environmental impact. In Perth’s sunny climate, solar hot water systems and heat pumps are great choices due to their energy efficiency and environmental benefits. For homes with lower hot water demand, gas instantaneous systems or electric instantaneous systems may be more practical.

By considering these factors, you can choose a system that meets both your needs and your budget while reducing your energy consumption. If you’re unsure which system is right for your home, don’t hesitate to consult with a professional installer in Perth to get expert advice tailored to your specific needs.
