Continuous Flow – How it works.
When a tap in the home is turned on, cold water flows into the continuous flow system through a pipe at the bottom of the unit. An inbuilt sensor automatically detects the water flow and then energises the heating element.
The heat from the heating coils, heats the water flowing through a heat exchanger. The water is heated to approximately 50*C and then flows out of a pipe at the top of the unit to the outlet.
Single and Three phase electric instantaneous water heaters are perfect for under-sink applications like Bathrooms, Kitchens and Showers for those who want to use less hot water and electricity.
They are energy efficient, simple to install, and you can monitor the temperature of your water with ease. For indoor instantaneous hot water, try our single-phase units. Access an instant supply of hot water in your home or office. Our range of units are intelligently designed and will adjust the power consumption to maximise energy efficiency.
Looking for something more powerful?
Take a look at our range of Electric Boiler 3 phase electric instantaneous hot water systems. We stock 3 phase units (perfect for large kitchens or to cater for large volumes of hot water. Our range of hot water heaters come with varied commercial and residential warranties to ensure you have a reliable source of hot water for years to come.
Instantaneous water heaters, also known as tankless water heaters, continuously heat water as it passes through the system and eliminates the need for a large water tank (that can take up too much space). Instead of heating water all day in a tank that might not be needed, our instantaneous electric hot water systems only heat water when there’s a demand. This helps to save energy and eliminate the “standby heat loss” that occurs in heaters with tanks.

When a tap in the home is turned on, cold water flows into the continuous flow system through a pipe at the bottom of the unit. An inbuilt sensor automatically detects the water flow and then ignites a gas burner.
The hot exhaust gases from the burner rise up and warm the water flowing through a heat exchanger. The water is heated to approximately 50 degrees and then flows out of a pipe at the top of the unit to the outlet.
Also often referred to as "instantaneous", a continuous flow HWS heats only as much water as you need, when you need it. They aren't truly instantaneous - it can take a few seconds before hot water starts flowing from the tap, especially when there's a fair distance of pipe between the HWS and the tap.
Most models use gas, but electric models are available.
As there are no heat losses as with water stored in a tank, they're often cheaper to run than storage systems.
Electric models will use the full electricity tariff for whenever they are in use, so running costs may be higher than for an off-peak tank, but less than a continuous tank system.
The size you need (flow rate in litres per minute) depends more on the number of hot water outlets the heater has to serve than on the number of people in the household. As a general rule, for a two-bathroom house you need a flow rate of about 22–24 L/min. Talk to your supplier to find the right capacity for your home.
We've had members advise that their continuous flow water heaters were not turning on because of a combination of low flow showerheads and too high a trigger point for the hot water heater to start up; essentially, the water flow was not sufficient for the water heating to be triggered. Keep this in mind if you are considering having low-flow shower heads and a continuous flow hot water heater, and confirm the trigger point is set appropriately.
