Water leakage safeguard for central heating installations

摘要

A water leakage safeguard for central heating installations is described which comprises a boiler, at least one radiator and associated flow lines and return lines. The water leakage safeguard consists of a valve device, in particular a non-return valve device at the return connection of the radiator. The valve facilitates repair work on the central heating installation, in particular on individual radiators, because evacuation of the entire heating installation becomes unnecessary owing to the valve arrangement.
