Observe these instructions for space heating water

Unsuitable heating system water can promote the
formation of scale or sludge, which affects system
efficiency. It can also cause corrosion and reduce life
of the heat exchanger.
• You must follow Buderus guidelines for boiler water
quality.
• Thoroughly flush the system prior to filling.
• Use of a Buderus approved boiler cleaner is
recommended.
• Never use salt bedding exchangers to soften the
water.
• Do not use inhibitors or other additives unless
approved by Buderus for that purpose!
• When frost protection of the heating system is
desired, only use Buderus-approved Aluminum-
safe antifreeze.
• When using oxygen-permeable pipes, e. g. for floor
heating systems, you must separate the system
using heat exchangers.
The maximum permissible flow rate of the GB142-
•
24/30 this is 11 GPM (gal./min.)(= 42 l/min.), for
the GB142-45 is 15 GPM (= 57 l/min.) and for the
