REMEHA HOT WATER CYLINDERS
OVERVIEW
INTRODUCTION
60% of the buildings that will be standing in 2050 are
already here with us today. So tomorrow, there will be a
great need for intelligent heating technology specifically
designed for refurbished buildings. This is where Remeha’s
advanced thinking is leading the way. To a future where our
highly efficient heating systems help to improve the overall
energy efficiency of refurbished buildings. Giving them new
life and a more sustainable future.
Remeha is committed to helping create a more
sustainable future with our comprehensive range of
energy-efficient, low-carbon heating solutions. Our
superior quality, British-manufactured hot water cylinder
range offers 24 options of Unvented Direct, Indirect
and Solar cylinders with 400l, 500l, 800l, 1000l, 1250l,
2000l and 2500l models available in each of the three
categories. A range of optional immersion heater units is
also available to provide boost and backup.

WHY CHOOSE DUPLEX
STAINLESS STEEL?
Remeha Commercial cylinders are manufactured from Duplex
2205 stainless steel to EN 1.4462, ASTM S3 2205/S31803 (with
PRE value of 35). This Ferritic-Austenitic steel combines high
strength, excellent corrosion resistance and stress corrosion
cracking resistance as well as excellent pitting resistance.
This marine-grade Duplex gives a low thermal expansion and
high chloride resistance. It has a great strength-to-weight
ratio which allows the finished cylinder to be substantially
lower than other materials.
2205 is a high specification grade of Duplex stainless steel,
making it highly suitable for commercial water cylinders. 2205
has approximately twice the proof strength of standard 304
and 316 types of stainless steel, meaning it is well equipped
to deal with the system pressures involved. The pitting and
crevice corrosion resistance in potable water is greater than
that of 316 stainless and other leaner alloyed Duplex stainless
types often used in water cylinders. End users can therefore
be assured of a long trouble-free service life.
The Duplex metallurgical structure is carefully balanced to
provide dual austenitic and ferritic phases, which provides
the high strength level and acts as an effective impediment
to stress corrosion and cracking.
Remeha Commercial cylinders come with a 6 bar
operating pressure as standard. The design options
being maximised by this choice.
* Depending on incoming cold water temperature and primary flow conditions.

Flow rates are crucial to today’s
hot water specifiers
We have all been in a hotel where the shower does not
perform and we have to run around to get wet. Why? Because
the hot water system was not designed correctly. Today this
all changes with Remeha Commercial, typically massive flow
rates in excess of 100 litres/min can be achieved. If you have
higher than that coming in, the cylinder will deliver that too.

Heat recovery in minutes, not hours

REMEHA HOT WATER CYLINDERS
OVERVIEW
Remeha’s range of Hot Water Cylinders meets all British environmental legislation and regulation standards
as well as EU Directives. This includes the recommendations of HSE Document L8 relating to Legionella
Pneumophilia, with the cylinders containing a minimum of two inspection ports (three on larger models) and
three optional destratification loop kits to circulate the hot water and enable pasteurisation.

CODES OF PRACTICE/LEGISLATION
EU Directives
Pressure Equipment Directive 97/23/EC.
Low Voltage Directive (LVD) 2006/95/EC.

Components supplied comply with the following standards:
BS EN 1490 Building Valves – Combined Temperature and
Pressure Relief Valves.
BS EN 1491 Building Valves – Expansion Valves.

Remeha Commercial cylinders are designed in such a way
that if provided with the prescribed heat input, the units
will recover from cold in less than 60* minutes. This is done by
the inclusion of super high performance coils or commercial
electrical elements.

Electromagnetic Compatibility (EMC) Directive 2004/1 08/EC.

Remeha Hot Water Cylinders are approved and certified by a
third party for safety and performance and manufactured in
the UK.

LEGIONELLA PNEUMOPHILIA
– MEETING RECOMMENDATIONS OF HSE DOCUMENT L8
•	 It is the responsibility of us all to consider the safety of
others when designing and installing hot water systems.
Advice on doing so is contained in HSE document L8,
this advice is heavily detailed and precise
•	 Essentially, it is recommended that any cylinder should
have access for inspection and cleaning, a system of
pasteurisation and where possible dead legs in the system
are designed out
•	 R
 emeha Commercial provides features which meet
these needs.
•	 A minimum of two inspection ports (three on larger models)
•	 T
 hree optional destratification loop kits (shunt pumps)
are available to circulate the hot water from top to bottom
to enable pasteurisation

Disinfection taking place

Some large cylinders have high heat losses, substantially
increasing fuel costs and pollution. All this ends with the
Remeha Commercial range.
•	 The Remeha Commercial range of cylinders are insulated
with 100mm of polyurethane foam of initial K-value 0.024
W/m.k, flammability to BS 4735
•	 The foam is applied to all surfaces of the cylinder including
around the legs and the lifting lugs at the top
Remeha Commercial cylinders are fully approved
and certified.
Typically calorifiers are made to British and European
manufacturing standards. These units are generally
bespoke and essentially one-off, the performance
is not tested or qualified by any third party. Claims
made for performance will be based on calculations
rather than testing.
That is not the case with Remeha Commercial
cylinders. The range has been tested by Kiwa and
Nemko for safety and performance. They are built
entirely in a purpose‑designed manufacturing facility
in the UK.

Progressively we are being educated to consider the environment when
making choices which have an environmental impact. Renewable energy
sources should be considered not only for their reduction in one’s
carbon footprint but also as they make fiscal good sense.

Depending on the choice of elements the cylinder is capable of heating
from cold in less than 60 minutes.

Remeha Commercial cylinders offer a range of direct cylinders which
when combined with our range of electrical elements can give the
specifier multiple options of generating hot water.

REMEHA HOT WATER CYLINDERS
WARRANTY
WARRANTY

NOTES

Remeha Commercial guarantees the water heater cylinder against faulty manufacture or materials for a period of
two years from the date of purchase including parts and labour. This two year guarantee is extended to five years
for the cold water control valve and to 25 years (from the date of installation) for the stainless steel inner vessel.
These guarantees are valid provided that:
•	 The water heater has been installed by a competent
engineer and as per the instructions contained in the
installation manual and all relevant Codes of Practice
and Regulations in force at the time of installation
•	 Any disinfection has been carried out in accordance with 
BS 6700
•	 Should the factory fitted temperature and pressure
relief valve be tampered with or removed your guarantee
will be invalidated
•	 The water heater has not been modified in anyway other
than by Remeha approved engineers
•	 The water heater has only been used for the storage of
wholesome sanitary water (max 250mg/l chloride)

NOTES PAGE

•	 The water heater has not been subjected to excessive
pressure beyond the guidelines detailed in the
installation instructions
•	 The water heater has not been subjected to frost, nor has it
been tampered with or been subject to misuse or neglect
•	 No factory fitted parts have been removed for unauthorised
repair or replacement
•	 Regular maintenance has been carried out by a
competent person in accordance with the requirements
set in the maintenance section of the installation
manual and any replacement parts used should be
approved spare parts
•	 The guarantee is not valid outside of the United Kingdom

•	 Only stainless steel dummy plugs are to be used

The warranty does NOT cover:
Consequential damages or profit loss which may arise from a defect.
Warranty claims have no delaying effect on the payment dates and other demands.
Your Remeha warranty covers you for an equivalent replacement and labour in the event that the unit fails
prematurely as a result of a proved manufacturing defect.
In order that this can be achieved, full access for removal and replacement of the unit is essential. If it is found that
access can not be achieved the warranty will be limited to the replacement of the unit only and subsequent labour
charges would not be met under the warranty.
