Storage Hot Water Systems in Geelong & Torquay
Storage hot water systems remain one of the most common and reliable ways to supply hot water to homes across Geelong, Torquay and the Bellarine. These systems heat and store hot water in a tank, ready to use whenever you turn on a tap, shower or appliance.
They’re a popular option for households that want a proven, cost-effective system that’s simple to operate and maintain. At Tomlinson Plumbing, we supply, install, service and replace gas and electric storage hot water systems to suit homes of all sizes.
What is a Storage Hot Water System?
A storage hot water system works by heating water inside an insulated tank and storing it at a set temperature until it’s needed. When you use hot water, cold water refills the tank and is reheated ready for the next use.
Unlike continuous flow systems that heat water on demand, storage systems keep a reserve of hot water available.
Storage systems are available in a wide range of tank sizes and can run on either gas or electricity, depending on your home’s setup and preferences.
How Storage Hot Water Systems Work
Storage systems operate on a simple and proven principle:
-
Cold water enters the tank and is heated by either a gas burner or electric heating element
-
The tank stores hot water at a controlled temperature
-
Hot water is delivered instantly when you open a tap
-
Once the tank is drawn down, the system reheats the next batch of water
Tank size, recovery time and household usage patterns all play a role in how well a system performs day-to-day. We help you choose the right size so you’re not running out of hot water – or paying to heat more than you need.
Benefits of Storage Hot Water Systems
Storage hot water systems remain popular across Geelong and Torquay for good reason:
-
Reliable hot water supply – hot water stored and ready to go
-
Multiple size options – suitable for small households through to large families
-
Choice of energy source – gas or electric options available
-
Lower upfront cost compared to some on-demand systems
-
Simple technology – proven, durable systems with straightforward servicing
While storage systems do have some heat loss over time and can run out if demand is very high, choosing the right size and system type helps minimise these issues.
Gas vs Electric Storage Hot Water Systems
Gas Storage Hot Water Systems
Gas storage systems heat water using a gas burner beneath the tank. They’re well-suited to larger households and higher hot water demand, as they tend to reheat faster than electric systems. Gas storage systems are a great option if your home already has natural gas connected.
Electric Storage Hot Water Systems
Electric storage systems use internal heating elements to heat the water inside the tank. They’re often simpler to install and can be a good option for homes without gas. Many households pair electric systems with off-peak electricity tariffs to help reduce running costs.
If you’re unsure which option suits your home best, we can talk you through the pros and cons based on your household size, usage habits and energy availability.
Choosing the Right Size Storage Hot Water System
Correct sizing is critical for comfort and efficiency. A tank that’s too small may run out during busy periods, while an oversized tank can increase running costs due to unnecessary heat loss.
When helping you choose a system, we consider:
-
Number of people in the household
-
Number of bathrooms
-
Typical hot water usage patterns
-
Simultaneous use (showers, washing machine, sinks)
-
Available installation space
We’ll recommend a size that comfortably meets your household’s needs without overspending on capacity you don’t need.

? Frequently Asked Questions
Q. How long do storage hot water systems last?
Most quality systems last 10–15 years with proper installation and maintenance, depending on usage and water quality.
Q. How often should storage hot water systems be serviced?
A check every two years can help identify leaks, worn components and safety issues before they turn into costly failures.
Q. Do I need a tempering valve with a storage hot water system?
Yes – hot water needs to be stored at a certain temperature to help prevent Legionella bacteria. The storage temperature is too hot for us to use, so tempering valves are installed to help regulate water temperature at your taps to reduce the risk of scalding. We can install and service these as part of your hot water system setup.
