Prextherm RSW Quadra 

Pressurised steel boilers 

The PREXTHERM RSW 

Quadra series heat 

generators are 

pressurised combustion 

boilers with flame 

reversal in the 

combustion chamber 

and three flue 

gas passes. 

18 models 

available from 

92 to 1890kW 


The shape design of the heat exchanger ensures an optimum ratio between the combustion 

volumes and the heat exchange surfaces 

The materials used ensure the long life of the boiler 

New turbulators improve the heat exchange of the flue gas and at the same time ensures a lower 

pressure drop 

A baffle plate has been fitted at the central heating system return inlet to improve the circulation of 

cold water towards the bottom of the boiler. This solution ensures more uniform distribution of the 

heat exchange fluid across the boiler’s heat exchange surface, achieving maximum heat exchange 

with less stress on the walls 

The tube bundle has been positioned above the combustion chamber, so that the flue gas is always 

discharged into a “hot”environment, preventing condensation forming 

The burner is not aligned with the combustion chamber, but rather has been moved downwards. 

This assists the reversal of the flame, reduces the pressure drop on the flue gas side and as a 

consequence extends the operating range of the generator 

The combustion chamber is completely cooled (even at the rear), to ensure a greater heat exchange 

surface and improve the distribution of the heating load across the walls 

The steel body is completely lined with an 80mm thick layer of glass wool, in turn covered by a sturdy 

layer of tearproof material 

The door can be hinged on the right-hand or left-hand side, has a double door stop with a newconcept 

locking and centring system. The door lining in the “Quadra” is made from ceramic fibre

heat exchange fluid across the boiler’s heat exchange surface, achieving maximum heat exchange with 

less stress on the walls 



The burner is not aligned with the combustion chamber, but rather has been moved downwards. This 

assists the reversal of the flame, reduces the pressure drop on the flue gas side and as a consequence 

extends the operating range of the generator

Aquacyl Twin Coil 

High quality stainless steel hot water cylinder 

for use on unvented hot water systems 

Aquacyl twin coil cylinder is ideal 

for solar water heating. 

The lower coil can be heated by 

energy from the solar collector. 

If hot water is required at a higher 

temperature than can be achieved 

by solar energy alone, then a Ferroli 

High Efficiency boiler fires and heats 

the upper coil to boost the water 

temperature. Alternatively the 

cylinder’s electric immersion 

heater(s) may be used to boost 

the hot water temperature.
