Calorifier System - Beta Marine BV1305 Operation And Maintenance Manual

CALORIFIER SYSTEM

All Beta engines can be fitted with
the engine tappings to allow the hot
water from the closed fresh
water/antifreeze system to circulate
through a calorifier tank which in
turn heats up domestic water.
Calorifier tappings on this range of
engine are shown.
1. The big problem with a calorifier
is to remove all the air from the
system. If this is not achieved
then they don't work!
2. Try and keep the supply and
return pipes either horizontal or
sloping down in a continuous fall
towards the calorifier. This avoids
air pockets being created.
3. Extra care must be taken when
first filling the calorifier circuit
system with 50% antifreeze to
water solution as the engine 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 mins. Top up the
water level as required and run
for another 10 minutes then
repeat.
4. 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.
