5 ) Drainage of condensed water must be provided by a pipe with a minimum diameter of 100 mm for 10K
and 160 mm for 15K. It is permissible to use a drain inserted vertically into the ground for a minimum of
90 cm, if the ground is permeable to water.

8 ) A CH buffer is recommended in thermally upgraded facilities.
9 ) Recommended methods against freezing:
A. Use propylene antifreeze throughout the system to -7°C. Increase the flow rate by 10% on the
circulation pump. Glycol concentration must not exceed 35%.
B. Use of a system with manual removal of water from the exchanger. Two drain valves in the form
of shut-off valves should be installed in the building to remove water from the exchanger by gravity.
Additional two shut-offs to prevent the removal of water from the rest of the system.
