how does it work? eco power shower technology
Pressurised air is ducted from a small
(remote or integrated) air pump unit to
the shower water outlet, and from there
along the co-axial hose to the handset
which houses Kelda’s ‘Flexion Venturi’
engine (developed in conjunction with
Southampton University). The engine
accelerates the air and uses it to break
up the water into droplets and increase
their velocity. This creates a forceful
and consistent shower spray at the
desired temperature and eliminates the
need for a water pump.
The user is able choose the
power of the spray boost and
an adjustable handset affords
control over the spray angle
Kelda technology utilises air
recycled from the shower
enclosure. Recycling air ensures
that the heat energy from a hot
shower lost to the surrounding
air is re-used
Compatible with Gravity-fed, pressurised and Combi-boiler water systems (3 ltr/min+).
- Low-performance gravity-fed showers can be greatly improved with Kelda boost.
- Two showers can be run simultaneously using a low-power Combi-boiler (~15kW).
Remote air pump unit can
be integrated with digital
& electric showers units
Makes an 8.5kW electric shower
more powerful than a standard
10.5kW without the need to
upgrade domestic wiring

reducing waste
‘The key to water efficiency is reducing waste, not
restricting use’ - Waterwise
With conventional mixer & power (pumped) showers, only a small
proportion of the water used makes contact with the body, with
the remaining volume acting as propellant. This additional water
and the energy used to heat it is wasted. Mixer and power
showers typically have a flow rate of 10-20 litres/min.
Excerpt from New Scientist Article, Dec 2011.
‘Clean Tech in Stormy Times’ - Carbon Trust.
‘(Kelda) set out to improve things. (They) designed a shower head
that combines high-pressure air with hot water and found they
could create a shower with less than half the normal amounts of
water and energy’.
Kelda technology efficiently propels a much lower water flow
with high-speed air. Typically, a flow of 5-6 Ltr/min will deliver a
comparable experience to a typical mixer shower at double the
flow, whilst generating significant savings in water consumption,
energy use and on utility bills. It’s efficiency without compromise.
