How Does a Continuous Flow Heater Work?
A continuous water heater is a modern hot water unit that delivers hot water only when you need it. Unlike storage tank systems, these units don’t store water. Instead, they heat it instantly as it flows through the system.
This approach suits many Thornleigh properties, from apartments where space is tight to larger homes with higher demand.

How Continuous Flow Hot Water Systems Deliver Hot Water
Continuous water heaters use sensors to detect water flow when a hot tap is turned on. An internal burner or electric element heats water on the spot, sending it straight to your tap or shower.
There’s no hot water kept “on standby”, so you only use energy when you’re actually using hot water. Many models let you set your preferred temperature for extra comfort and safety.
Types of Continuous Water Heaters
You’ll find both electric and gas continuous hot water systems available in Thornleigh. Gas models are popular for their higher flow rates, making them a good fit for families or homes with multiple bathrooms.
Electric types are suitable for smaller dwellings or where running gas hot water systems is not practical. Both types can be paired with solar or other energy systems, depending on your goals and site constraints.
Installation and Maintenance Considerations
In Thornleigh, continuous flow hot water systems must meet specific local standards. Correct sizing is crucial. Too small a unit, and you could run out of hot water when demand is high; too large, and you’re likely spending more upfront than needed.
Regular maintenance, generally every two years, will keep your system efficient and help it last up to 20 years.
Our team is fully qualified to recommend, install, and service these systems, ensuring your heater matches your home’s requirements and complies with all relevant codes.

What Makes Continuous Water Heaters a Great Option
Choosing a continuous water heater for your property delivers real advantages in efficiency, comfort, and long-term value.
Our team at JSW Plumbing handles installation and maintenance for all major types, helping you get more from your hot water system without the common hassles of storage tanks.
Lower Running Costs With On-Demand Heating
A continuous water heater only uses energy when you open a tap, which means no wasted power keeping a tank hot all day. You end up paying for the hot water you actually use, reducing annual energy bills.
We see many Thornleigh homes, especially those with smaller households or uneven water use, benefit from this setup with noticeable savings.
Never Run Out Of Hot Water
Unlike traditional tanks, a continuous system doesn’t have a set limit. There’s always hot water available, whether your family is using several showers in a row or your business has high demand throughout the day.
Our plumbers help you select a unit with the right flow rate, so you get an uninterrupted supply. No cold surprises.
Compact Design Fits Tight Spaces
Continuous water heaters are much smaller than bulky tanks. They mount to a wall, freeing up precious space in Thornleigh’s often compact homes and apartments.
We’ve fitted these units in tight utility cupboards, laundry rooms, even outside on protected walls, saving space while still delivering reliability in hot water supply.
Less Maintenance, Longer System Life
Without a tank, there’s less chance of leaks, corrosion, or sediment build-up. Continuous systems typically need fewer frequent repairs when serviced regularly.
Our experts help with ongoing maintenance, flushing, and checks to keep your continuous water heater running smoothly and extend its service life.

Continuous Water Heater Installation Requirements
Installing a continuous water heater comes with a set of rules and checks, especially in Thornleigh. Our team at JSW Plumbing is fully up to date on these details and handles all installation steps to meet local standards.
Legal Standards for Hot Water System Installation
Every continuous water heater must be fitted by a licensed plumber under NSW law. Gas models follow the AS/NZS 5601.1:2013 standard, covering location, ventilation, and minimum clearances.
Electric units need to meet the AS/NZS 3000 wiring rules and require a licensed electrician for final hookup. After the job is done, we give you a Certificate of Compliance to show the work meets both local rules and manufacturer guidelines.
Site Location, Clearance, and Ventilation
Continuous flow water heaters cannot sit too close to combustibles or building openings. There are strict minimum distances to reduce any risk.
For example, at least 500mm from combustible surfaces and 600mm from doors and windows is required.
We also make sure any balcony or enclosed installations have proper venting, following all Sydney regulations. Good ventilation is non-negotiable to prevent gas build-up or unsafe operation.
Safety Devices and Temperature Control
A continuous water heater in Thornleigh must include temperature and pressure relief valves, as well as any tempering requirements for outlets used for bathing. Our plumbers install approved tempering valves where needed to prevent scalding and check all manufacturer-specified distances for a safe, compliant fit.
