Development of a warm water distribution system for the house water installation with internal circulation

In case of the patented HF inliner system the circulation line is largely integrated into the supply pipe in order to decrease the calorific losses during the warm water circulation. The water, which has cooled down on its way to the taps by calorific losses to the environment of the pipeline, is heated up on its way back to the hot water tank. The calorific losses of the return pipe are completely avoided and - compared to a conventional circulation system - reduced by up to 50 %.
