NEO fl o Water Heater 6 September 2015
COMBATING LEGIONELLA
All Codes of Practice draw attention to the design and
operation of water systems with reference to avoidance
of factors that favour colonisation by Legionella bacte-
ria.
Th ese factors include stagnation, lukewarm condi-
tions (20ºC to 45ºC) and the accumulation of debris,
scale and corrosion in the base of tanks and calori
fi ers.
Andrews Water Heaters has commissioned an inde-
pendent evaluation of their products to investigate
their resistance to build-up of Legionella bacteria.
Experiments were conducted to determine whether,
following a substantial challenge by Legionella Pneu-
mophilia, after overnight and stagnation conditions,
the system was rendered free from viable recoverable
Legionella. It was found that at 61ºC, following a chal-
lenge of approximately 107 organisms per litre, within
one hour, more than 99.999% of organisms had been
killed. After a subsequent stagnation period, sampling
did not reveal any residual contamination.
Th e design
of the base of the Water Heater precludes Legionella
colonisation, even after build-up of debris.
Th e burner
positioning ensures that the water at the bottom of the
heater reaches the same, or higher temperature as in
the rest of the heater.
Based on data obtained through experiment, this Water
Heater can be described as Legionella resistant as it is
considered unlikely that, at the temperature tested, the
organism would colonise the water heater and present
a possible health risk.
Water systems in buildings have been associated with
outbreaks of Legionnaires’ Disease, particularly in
health care facilities where occupants are signi
fi cantly
more susceptible to infection.
In recognition of the risks in hospitals, a Code of
Practice for the Control of Legionella in Health Care
premises has been issued by the Department of Health.
Codes of Practice applicable to other premises have
been published by other organisations, principally
the Health and Safety Executive (HS) (G70) and the
Chartered Institute of Building Services Engineers
(CIBSE, TM13).
DECOMISSIONING, DISPOSAL AND RECYCLING
Only quali fi ed competent persons should decommission and
dismantle the appliance.
Before dismantling and removing please ensure you safely
remove the power supply and isolated the appliance from the
water and gas connections.
Dispose of the appliance correctly according to the laws and
regulations in force.
Th e appliance and accessories cannot be
discarded along with normal household waste and should be
recycled where appropriate.
More than 90% of the materials that make up the appliance
are recyclable.
