DESCRIPTION OF FUNCTION
“Tank-in-Tank” system
“Tank-in-Tank” is a heat exchanger with a built-in accumulator, made
up of two concentric tanks: the inner tank contains domestic water
to be reheated (secondary) and the outer tank contains the heating
fluid (primary) which circulates between the two tanks and transfers
its heat to the domestic water.
Domestic Hot Water cylinder
The inner tank is the heart of the tank: it is subject to the
aggressiveness of the supply water, to high pressures and to
variations in temperature. This tank is made of solid chrome-
nickel stainless steel (stainless steel 304), fully welded under argon
protection using the Tungsten Inert Gas (T.I.G.) technique.
Before assembly, the convex bottoms are pickled and passivated in
order to improve the tank’s lifespan and in particular its resistance to
corrosion. The shell is corrugated all the way up using an exclusive
manufacturing process. This design gives considerable resistance to
pressure and limits the adherence of lime scale by allowing the tank
to expand and contract.
Outer tank
The outer tank containing water from the primary circuit arriving
from the boiler, is made of carbon steel STW 22.
Thermal Insulation
This is carried out using high density injected polyurethane
foam, 50 mm containing no CFCs.
Lining
The tank is covered using polypropylene, a plastic material
which offers a high resistance to shocks and which is also very
pleasing to the eye.
Optional heating element for SLE Plus
The SLE tanks can be installed with a self- controlled heating
element with built-in control and safety thermostats.
The control thermostat of the tank can not control the heating
element.
DESCRIPTION OF OPERATION
Operating cycle
The thermostat is triggered and starts up the pump which circu-
lates the heating water. This water circulates around the inside tank
and heats up the domestic water. When the required temperature
is reached, the thermostat stops the primary circulating pump.

INSTALLATION
This hot water tank should not be installed where it will be exposed
to outside weather conditions.
Choose the most appropriate location according to the position of
the boiler and the proximity of the domestic hot water distribution
system, in order to reduce heat losses and minimise the pressure
drops.
Floor standing installation only.
