ACV UK is a subsidiary of the ACV International
Group that has been designing, manufacturing and
marketing technological systems for hot water
generation since 1922. ACV International was
founded in Belgium and pioneered the Tank-in-Tank
concept – a cutting edge design providing
exceptional performance.
All products are manufactured on two production
sites in Belgium and in the USA. Through fourteen
subsidiaries and a broad network of specialised
distributors, ACV has a presence on all five
continents.
Most ACV products are based on the Tank-in-Tank
concept. This technology gives our products
exceptional performance in hot water and heating
generation.
Today, ACV offers innovating products that fulfil all
the demands of a modern world, thanks to the
advanced exclusive technology; we offer solutions
that are reliable, high performing, economical and
environmentally friendly.
Introduction
The Tank-in-Tank is a HW tank entirely immersed
within an outer tank which contains the primary fluid,
with the inner tank itself being a stainless steel heat
exchanger. The corrugated wall of the inner tank forms
a large heat exchange surface that can heat the
domestic water in a very short time. It also provides a
uniform temperature throughout the volume of the
tank. Since the inner tank can move freely, it can
expand and contract under changes in pressure and
prevent limescale forming on the surface.
This simple and highly effective design allows specifiers
and installers to benefit from the cost advantages of
ACV’s high volume production while taking comfort
from the fact that the system they are specifying or
installing is the best available. Key Features
• A specially designed stainless steel hot water
cylinder enclosed within an outer tank which is
heated by the boiler
• The inner tank also acts as a large thermal store, and
is surrounded by primary hot water. Recovery is
exceptionally fast because the heat transfer surface
is so large
• The internal cylinder is designed to operate at up to
10 bar - suitable for any kind of application, mains
pressure or vented
• Sides of the cylinder are corrugated which increases
the heat transfer area. Expansion and contraction in
use shrugs off scale deposits
• Each draw-off causes natural turbulence keeping
particles in suspension
• Stainless steel construction means no anode
protection, no contamination, leaking or sludging
caused by cracked glass linings. Water held at
consistently higher temperatures discourages
growth of Legionellae bacteria

SmartLine SLE
and SLE Plus
Fast recovery ank-in- ank cylinder
– standard 3kW immersion, perfect
partner to condensing boilers and
heat pumps.
ACV has adapted the proven Tank-in-Tank design of the SLE cylinder
to maximise its full potential. The addition of multiple ports on the
SLE Plus not only gives the installer flexible installation options but
also gives the customer a cylinder built with the future in mind!
Tank-in-Tank Technology
The tried and tested ACV thermal storage technology has proved to be
remarkably simple, efficient and reliable. An inner stainless steel
hot water cylinder is entirely immersed within an outer steel tank and
heated by the primary water: large heat exchange surface offering
greater heat transfer and therefore faster recovery times than any
other storage tanks.
Resistance to Scaling
The special design of the inner cylinder helps ensure scale-free
operation and avoids the sediment problems that plague conventional
cylinders.
Features
• 3.5 BAR mains water pack and mixing valve supplied
• 3 kW immersion as standard – 6kW option
• Future-proof design due to multiple ports (extra ports on
SLE 210-240-300 only)
• 6 pin plug-and-play, S Plan or Y Plan
• Low heat loss – 50mm polyurethane insulation
• Stainless steel domestic cylinder – 25 year guarantee

Fast recovery ank-in- ank
cylinder – perfect partner to
condensing boiler.
At a time when consumers are demanding higher performance from
their hot water installations, the traditional coil based cylinders find it
more difficult to deliver high volumes of water for the modern user.
ACV Tank-in-Tank technology represents a significant advance in the
science of hot water production.
A greater heat transfer surface means Tank-in-Tank units recover much
faster than any other type of hot water storage cylinder – keeping
boiler cycling to a minimum, and ultimately giving improved fuel
efficiency with outstanding hot water delivery.
