  • Page 12: Prolonged Standstill Of The System. Frost Protection

    8. PROLONGED STANDSTILL OF THE SYSTEM. FROST PROTECTION We recommend you avoid draining the whole system as water replacements engender purposeless and harmful limestone deposits inside the boiler and on the heating elements. In case the boiler is not operated during wintertime and is therefore exposed to danger of frost we suggest you add some specific-purpose anti-freeze to the water contained in the system (e.g.: propylene glycole coupled with corrosion and scaling inhibitors).
