Upgrading to a Larger Capacity Electric Hot Water System for Better Recovery Performance
Our team attended a property in Beecroft to complete a full electric hot water replacement, upgrading the existing unit with a new 315L twin element electric hot water system. Larger storage systems like this are commonly installed in family homes where consistent hot water demand is required throughout the day.
For this project, Pure Plumbing Professionals supplied and installed a new 315L twin element system, including updated valves and pipework modifications to ensure the installation complied with current Australian standards and manufacturer requirements.
This type of system is specifically designed to provide reliable hot water recovery for homes with multiple bathrooms or higher daily usage.
Why a 315L Twin Element System Was Chosen
A 315L twin element electric hot water system is designed for households that use large amounts of hot water across multiple fixtures at the same time.
Unlike smaller systems, a twin element setup allows the unit to recover hot water more efficiently throughout the day by using two separate heating elements within the tank.
This makes the system well suited to properties where:
- Multiple showers may run close together
- Larger families use significant hot water daily
- Demand is spread across morning and evening periods
The larger storage capacity also helps reduce the likelihood of running out of hot water during peak usage.
At Pure Plumbing Professionals, selecting the correct system size is an important part of ensuring reliable long-term performance.
Preparing for the Hot Water System Replacement
Before installation began, the site was prepared to safely remove the existing unit.
This included isolating both the electrical and water supply before draining down the old system.
Once isolated, the existing hot water unit was disconnected and removed from site to allow installation of the new system.
Safe isolation and removal are essential when replacing large electric storage systems operating under pressure.
Installing the New 315L Twin Element Hot Water System
The new hot water system was installed in the same location and connected to the existing water and electrical services.
Because twin element systems contain additional operational controls and heating functions, careful installation is required to ensure:
- Proper heating performance
- Balanced pressure throughout the system
- Reliable hot water recovery during heavy usage
Pipework was also altered and adjusted to suit the updated valve configuration and ensure compliance with installation standards.
Installing New Valves for Safety and Compliance
As part of the installation, new valves were supplied and installed, including a tempering valve, isolation valve, and pressure limiting valve.
These valves play an important role in protecting both the hot water system and the household plumbing.
The tempering valve helps regulate outlet water temperature, while the pressure limiting valve protects the system from excessive mains pressure.
Updating these components is often required during hot water replacement works to ensure compliance and maintain manufacturer warranty requirements.
Testing and Commissioning the System
After installation was completed, the electrical and water services were reinstated and the system was fully tested.
Testing included:
- Checking all pipework and valves for leaks
- Confirming correct heating operation
- Testing pressure and temperature performance
- Verifying the tempering valve was functioning correctly
Commissioning ensures the system is operating safely and delivering consistent hot water throughout the property.
What Most Homeowners Don’t Realise About Larger Electric Hot Water Systems
Many homeowners focus only on tank size, but recovery performance is just as important as storage capacity.
A larger twin element system not only stores more water — it also reheats water more efficiently during periods of heavy demand.
This can make a significant difference in homes where:
- Multiple bathrooms are used daily
- Hot water usage is spread across the day
- Existing systems regularly run out of hot water
Choosing the correct system configuration helps improve reliability and long-term performance.
When a 315L Twin Element Hot Water System Is Recommended
These systems are commonly recommended when:
- Household hot water demand is high
- Larger families require a consistent supply
- Existing systems cannot keep up with usage
- Faster hot water recovery is needed
A properly sized hot water system helps ensure the household has reliable access to hot water throughout the day.
