Double flow path radiator for heating system - has inside and outside counterflow tubes for improving heat transfer

The radiator used in central heating systems has two flow channels to ensure uniform temp. on the radiator outside wall. The heating arrangement has an outside and inside tube (10, 16) and a closing piece (12). At the other end is arranged a connector (24) which supplies the medium directly into the annular space (35) between the two tubes. The outside tube has a number of thin ribs (25) for improving heat transfer to the room. The medium enters the inner tube flow channel (30) through holes (18) near the closed ends of the tubes. Hence heat transfer takes place between the medium in the annular space and the inside tube by counterflow. The medium in the annular space has uniform temp. from the inlet point to the outlet to the inside tube.

Heating system for a room accommodating a staircase, in particular of a single-family dwelling

In the heating system, the banisters are incorporated into the heating system. To this end, the two rails and some of the banister rods are of hollow design. Expediently, the upper rail serves as inlet and the lower rail as outlet for the heating medium, while the banister rods are flowed through like a radiator from the top to the bottom.
