Draining the heating system
Another way to protect the heating system and the boiler
from frost when they are switched off for a very long time
is to drain them. You must ensure that the heating installa-
tion and boiler are completely drained.
All the cold and hot water pipes in the house and in the
boiler must also be drained.
>
Ask your heating engineer to drain the heating installa-
tion.
