Continuous Flow Hot Water Installation and Repairs

Instantaneous hot water systems (continuous flow units), heat water only when you need it.
This on-demand approach means you are never paying to heat a tank full of unused water and you never run out mid-shower.

For many Wollongong homes, gas-powered instantaneous systems are the go-to choice due to their fast heating, compact size, and energy efficiency.
But if you do not have access to gas, newer electric models are now available with comparable running costs and performance, particularly when paired with solar power or off-peak electricity.

At CS Plumbing Services, we install, service, and replace continuous flow hot water systems for homes and small commercial properties across the Illawarra.

What is an Instantaneous Hot Water System?

Unlike traditional storage tanks that heat water in advance, an instantaneous system heats water as it flows through the unit. That means:

No storage tank
No standby energy loss
Endless hot water supply
Small wall-mounted footprint

These systems are ideal for households that want efficiency, need to save space, or are replacing an old tank system with something more modern.

Gas vs Electric Instantaneous Systems

Gas Instantaneous
The most common type in Wollongong homes, these systems heat water quickly and efficiently. They are especially cost-effective where natural gas is already connected. LPG versions are available for properties without mains gas.

Electric Instantaneous
While less common, modern electric continuous flow systems are now available that approach the running cost efficiency of gas. They are a smart option when used with solar or off-peak tariffs and are ideal for homes where gas is not available.

We can advise you on which type makes the most sense for your home’s energy setup and hot water demands.

Instantaneous Hot Water FAQS

An instantaneous hot water system heats water only when you turn on the tap. Unlike storage systems, it doesn’t store hot water in a tank, helping provide endless hot water on demand for your home.

They can be! Because they only heat water when needed, many homeowners find they’re more energy-efficient and cost-effective compared to older storage units. This can help reduce your gas or electricity bills over time.

This can happen due to low gas pressure, system overload, faulty sensors, blocked filters, or temperature settings issues. If your hot water keeps cutting out, it’s best to have a licensed plumber inspect it for safety and performance.

Yes, but the system must be properly sized for your home’s hot water demand. A professional plumber can recommend the right unit based on the number of bathrooms, household size, and usage needs.

In most cases, installation can be completed within a few hours to a single day, depending on the existing plumbing setup. CS Plumbing & Drainage Services installs instantaneous hot water systems across Wollongong safely and to Australian standards.
