Technical Detail

Thermal Efficiency up to 94.0% – Fully condensing design.
Three Pass Flue System – The three pass flue system keeps
the hot combustion gases moving at a high velocity. The
combination of high turbulence and velocity causes an
enormous rate of heat transfer into the water.
Low NOx Premix Power Burner – Developed for the ECOflo
Range, a turbulent flame shoots down the submerged
combustion chamber. This turbulence causes a thorough mixing
of the gas and air for optimum combustion and high heat
transfer efficiencies.
Submerged Combustion Chamber – Submerging the
combustion chamber in the centre of the water storage tank
minimizes radiant heat loss and improves efficiency.
Non-CFC foam insulation – Surrounds the tank surface, saving
energy by reducing heat loss.
Electronic Controls – Adjustable electronic thermostat 27°-
82°C recycling Energy Cut Off (E.C.O.) shuts off all gas in
event of an overheat condition.
Zero Inch Clearance – The ECOflo external jacket is cool to the
touch and is approved for zero inches to combustibles for
unsurpassed installation flexibility.
Vitraglas® lined tank – Andrews Water Heater tanks are
protected from the corrosive effects of hot water by an exclusive
ceramic porcelain-like coating. Our high silica Vitraglas® lining
provides a tough interior surface.
Electrically powered anodes – Each ECOflo product is
supplied with a factory fitted Andrews Correx Powered Anode
system. This significantly reduces service time due to the
anodes being maintenance free.
Factory installed Hydrojet® Sediment Reduction
System – Cold inlet sediment reduction device made of
stainless steel for increased durability. Helps prevent sediment
build up in tank.
Factory installed dielectric fittings – All heaters are equipped
with special water heater nipples for longer heater life. No
special dielectric fittings to buy.
Flexible fluing – The ECOflo range can be flued vertically or
horizontally with a 100/150mm concentric flue pipe system.
The maximum flue run length is sixteen metres from the
appliance connector to the terminal. The overall length
is reduced if an elbow or condensate trap is fitted (see
below).
