Connecting apparatus for a radiator

摘要

The invention relates to apparatus for connecting a radiator to a single or double tube type hot water central heating system. The connecting apparatus includes a conventional thermostatic valve and a conventional valve controlled bypass between the inlet and outlet connectors of the connecting apparatus. A constructural feature which results in lower manufacturing costs and a lower stock inventory for thermostats involves a return passage from the radiator outlets which has a setting valve that is actuatable independently of the bypass valve.
