CFEWH Benefits
Key Benefits
The key benefits of the CFEWH are:
Decreased infrastructure costs
•
At low flow rates, hot water temperatures cannot exceed 50°C, which therefore eliminates the
requirement for tempering valves or thermostatic mixing valves, unless otherwise specified as per AS
3500 Section 1.9.2.
•
Point of use installation significantly reduces requirement for hot water reticulation infrastructure.
Small Footprint
•
Facilitates point of use installation.
•
Easy to install.
Decreased operating costs
–
and minimal water wastage
•
Always operates at “optimimum” power.
•
Switch-on flow rate is as low as 1.5ltr/min.
•
No requirement to heat water in anticipation of use.
•
Stable hot water temperatures are delivered.
•
Reduced water consumption due to reduced draw off.
•
Hot water reticulation energy losses significantly reduced.
•
Virtually maintenance-free: no scaling or element burn out.

“Optimised” Energy
“Optimised” energy
is the capacity to heat water more efficiently
–
delivering reductions in the consumption
of both energy and water.
Reduced energy consumption
•
Lower flow rate = less water volume to be heated and less energy is consumed.
•
Lower temperature change required = less
energy is consumed.
Reduced water consumption
•
Hot water temperature stability = less water is consumed.
•
The lower the flow rate = less water is consumed.
Of course, the ideal situation would be for EIWH appliances to have some degree of
“optimised”
energy
–
however,
most do not incorporate this.
Significantly, the
100% “optimised” energy
delivered by the CFEWH results in far less than the full rated power
being consumed.
