What makes this product so unique 
and different?

The Continuous Flow Electric Water Heater [CFEWH] 
uses innovative new technology to deliver hot water 
instantly … and achieve impressive efficiencies in both 
water and energy usage.

We’d like to explain how it’s so different from other hot 
water systems – and why it’s setting completely new 
standards.

To fully appreciate the difference – and the substantial 
benefits – offered by the technology used in this water 
heater, we need to start off by comparing the main 
deficiencies of traditional hot water systems.

Heating water the traditional way

Traditional centralised hot water services consume 
continuous energy to heat water and then maintain it 
at a defined (thermostat-controlled) temperature, ready 
for when it’s wanted. Typically, the water heater is 
located away from where the water is wanted, relying on 
lengths of pipe to deliver the water. Energy is therefore 
wasted keeping quite a large volume of water at a stable 
temperature – often at a higher temperature than would 
ever be used. 

But that’s not all – water is wasted every time a hot water 
tap is turned on. That’s because you need “to let the 
water run” until the water held in the pipes has made way 
for the hot water you want, coming from the water heater.

The overall result is quite inefficient usage of power 
together with wastage of water.

The MicroHeat difference

The Continuous Flow Electric Water Heater [CFEWH] 
is a very compact unit, which provides an instant and 
continuous flow of hot water wherever it’s required – 
delivered through very short lengths of pipe. Water isn’t 
wasted, because you’re not leaving it running, waiting for 
it to get hot. Hot water is always at a stable temperature, 
despite any fluctuations in water pressure.

You don’t need a science degree to understand how the 
efficiencies and savings are achieved – all you need to do 
is follow our simple explanation.

The secret of “optimised” energy

The unit intelligently optimises the amount of energy it 
needs to heat water, depending on how much water you 
want. 

For example, let’s assume hot water is required at 45°C.

If you want a fairly fast flow of water – 4 litres a minute – 
the unit will use its full power – 9.6kW – to heat the water.

However, if you only want a low flow of water – 1.5 litres a 
minute – the unit will use just 4.2kW to heat the water.

The benefit is the unit can intelligently vary itself between 
being a 9.6kW and 4.2kW system. The lower flow rate 
achieves 56% less energy consumption – and that 
contributes to lowering power bills.

In addition, varying the flow rate of the water contributes 
to lower water consumption and achieves further savings. 
Reducing water flow from 4 litres a minute to 1.5 litres a 
minute lowers water consumption by 66%.

Incoming water temperature makes 
a difference

The unit also achieves savings in another area – by 
intelligently varying its power between 9.6kW and 7kW 
to heat incoming cold water. 

Depending on where you’re located and what season 
it is, mains cold water temperature could potentially 
fluctuate anywhere between 10°C and 25°C.

Let’s again assume hot water is required at 45°C and you 
want a fairly fast flow of hot water – 4 litres a minute.

If the incoming water temperature is a fairly chilly 10°C, 
the unit will apply its full power of 9.6kW – however, if it’s 
a pleasantly warm 25°C, it will only use 7kW. That’s 20% 
less energy consumption – making a further contribution 
towards lowering power bills. 

We hope you now have a better 
understanding of how the Continuous 
Flow Electric Water Heater [CFEWH] is 
revolutionising hot water.

Although the Continuous Flow Electric Water Heater [CFEWH] is very safe to use, this appliance is not intended for use by persons (including children) 
with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction 
concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

About the Continuous Flow Electric Water Heater [CFEWH]

    |    MicroHeat Technologies Pty ltd

MicroHeat designed and developed a method of heating 
water using electrode technology that is completely 
different to existing methods of water heating: the 
MicroHeat technology addresses unnecessary wastage of 
energy and water, as well as failures caused by scaling, 
overheating and stress corrosion normally associated with 
heat exchange technology.
