r
steel boilers are high efficiency boilers
with horizontal, flame reversal combustion chambers
and concentrically arranged flue gas pipes. They
are designed for central heating and, when used in
conjunction with a suitable storage cylinder, for domestic
hot water production too.
Because they operate at low pressure, they provide a
gradual heating action without thermal shock.
The most important technical features of these boilers are:
- The combustion chamber and heat exchange system
are specially designed and shaped to achieve the
best possible volume ratio.
- Only top quality materials are used to ensure a long
working life.
Stainless steel turbulators inside the flue gas pipes
establish an ideal pressure inside the combustion
chamber and an ideal flue gas temperature. Evenly
distributed thermal load optimises the efficiency of the
boiler-burner system.
The boiler body is thoroughly insulated with a layer of
high density glass wool.
The boiler’s front door and the flue gas box can be opened
completely to facilitate the inspection, maintenance and
cleaning of internal parts and to speed up servicing in
general.
The front door can open in either direction, even without
removing the burner.
