Draining the central heating system

Draining the central heating system may be necessary if the
radiators have to be replaced, if there is a serious leak, or if
there is a risk of freezing.
Drain the central heating system as follows:
• Open radiator valves and set the room thermostat as low
as possible.
• Switch off the boiler and wait until the radiators feel cold.
