Calorifier System

All Beta 'Green Line' engines are fitted with 'Calorifier Connections' to allow the hot coolant from the closed cooling system to
circulate through a calorifier tank, which in turn heats up domestic water. Photos are shown below.
1. The big problem with a Calorifier is removing all the air
from the piping /system. If you cannot get the air out,
then the Calorifier will not work!
2. Try and keep the supply and return pipes either horizontal
or sloping down in a continuous fall. This avoids air
pockets being created.
3. If your calorifier is installed above the engine then a
'Remote Header Tank kit' must be fitted.
4. Extra care must be taken when first filling the calorifier
system with coolant (a solution of water plus 30% to
50% antifreeze) as the header tank may appear to be full
but it soon disappears into the calorifier pipe work. Run
the engine off load for 10 minutes then check the level as
described in 'Filling the Fresh Water System'. Also check
to see if the pipe going to the calorifier is getting warm
after 15 minutes. Top up the water level as required and
run for another 10 minutes, then repeat.
5. If the water level is steady but no warm water is getting
to the calorifier then very carefully open the calorifier
bleed valve (see manufacturers instructions) or if none is
provided then very carefully loosen the jubilee clip
securing the supply pipe to the calorifier. Air should
escape. Refasten securely when no further bubbles are
seen.
Caution: Do not do this when the engine is hot as
scalding hot water may be forced out of the pipe under
pressure.
