FERROLI LIMITEDFerroli began producing heating appliances and equipment in Italy

during the 1950s. Today, the company is still family-owned but now

operates ten ultra-modern factories in Europe, employing over 2,500

people and producing a wide range of wall hung, cast iron and welded

steel boilers, making Ferroli one of the largest and most successful

heating appliance manufacturers in the world.

FERROLI COMMERCIAL AND INDUSTRIAL BOILERSThe commercial and industrial boiler range covers wall hung and floor

standing steel and cast iron designs, condensing, atmospheric, pressure

jet units, gas and oil models. Outputs range from 50kW to 14,000kW.

Other products include heat pumps, cylinders, solar heating and

plate heat exchangers. Ferroli’s UK warehouse, backed by its huge

manufacturing facility in Italy, offers delivery ex-stock for most smaller

boiler models and for all frequently used parts. It also assembles and

commissions sectional boilers in the UK to suit particular requirements.

PRODUCTIONThe division, ISO 9001 certified by TÜV SUD, operates in production facilities

covering twenty thousand square metres, including the factory, technical and

design offices and management-sales departments. Ferroli Industrial Heating

adopts a “project” approach: a team of professionals that can satisfy all

customer needs, the best technology applied in the production department

and the use of materials and processes compliant with EN standards mean

that all products are CE marked and approved in various foreign countries.

The manufacturing flexibility of the Ferroli facilities allows the company to

respond to a vast variety of market demands, from simple heating systems to

sophisticated installations for district heating and serving production plants.

Specialist engineers and technicians conduct level two non-destructive testing

(ultrasound, X rays, liquid penetrants) and various welding procedures qualified

by the Italian Welding Institute, according to the standard EN ISO 3834,

involving all the welding featured in our projects, including submerged

arc and TIG welding, welding with basic electrodes and flux-cored welding.

The investments made have allowed a high level of automation to be

reached in the cutting and welding process.

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 lowerpressure drop

A baffle plate has been fitted at the central heating system return inlet to improve the circulation ofcold water towards the bottom of the boiler. This solution ensures more uniform distribution of theheat 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 alwaysdischarged 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 aconsequence extends the operating range of the generator

The combustion chamber is completely cooled (even at the rear), to ensure a greater heat exchangesurface 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 sturdylayer of tearproof material

The door can be hinged on the right-hand or left-hand side, has a double door stop with a new-concept locking and centring system. The door lining in the “Quadra” is made from ceramic fibre

The PREXTHERM RSWQuadra series heatgenerators arepressurised combustionboilers with flamereversal in thecombustion chamberand three flue gas passes.

A baffle plate has been fitted at the central heating system return inlet to improve the circulation ofcold water towards the bottom of the boiler. This solution ensures more uniform distribution of theheat exchange fluid across the boiler’s heat exchange surface, achieving maximum heat exchange withless stress on the walls


The burner is not aligned with the combustion chamber, but rather has been moved downwards. Thisassists the reversal of the flame, reduces the pressure drop on the flue gas side and as a consequenceextends the operating range of the generator



The door can be hinged on the right-hand or left-hand side, has a double door stop with a new-concept locking and centring system. The door lining in the “Tonda” has a double cement lining plusan extra layer of insulating material
