cast iron boilers are high efficiency, triple
flue pass boilers with a horizontal combustion chamber
for central heating only (
g
N
) or for central heating
and domestic hot water production when equipped with
a 100 or 60 litre vitrified storage cylinder (
g
NK
).
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, including special MB18C
cast iron, are used to ensure a long working life.
The boiler body is thoroughly insulated with a layer of
high density glass wool.
The boiler's front door can be opened completely to
facilitate the inspection, maintenance and cleaning of
internal parts and to speed up servicing in general.
If equipped with an optional total shutdown control card,
r g
boilers can implement total shutdown logic
and save energy as follows:
-
g N
models only start up if the heating system
requests heat (i.e. when the room thermostat switches
the heating on).
- When the Summer/Winter selector is set to Summer
mode
g NK
, models apply total shutdown logic
and save energy by starting up only when a domestic
hot water tap is opened.
Both types of boiler have an overtemperature dispersal
function to disperse the heat left by thermal inertia.
