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 engineers at MicroHeat set out to create something
completely different from existing methods of providing
hot water: a highly efficient new method of heating water
that would address the wastage of valuable resources –
energy and water.
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.
