DESCRIPTION OF THE SPECIFICATIONS

“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.

Hot water exchanger accumulator

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 or duplex)

, 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

Soft polyurethane foam - 30 mm thickness.

Lining

Exterior of casing vinyl coated and polypropylene cap.

Electric heating element in HLE

The HLE tank is equipped with one 2200 W heating element 
controlled by the thermostat of the HLE.

INTRODUCTION

DESCRIPTION OF OPERATION

Operating cycle

The thermostat is triggered and starts up the pump which loads the 
heating fluid. This fluid circulates around the inside tank and heats 
up the domestic water. When the required temperature is reached, 
the thermostat stops the loading pump.
