Patent number: 6820818Abstract: A high-efficiency hydronic heating system will make use of a direct-fired steam generator to directly heat the water in the hydronic heating system. The products of combustion, present with the steam due to the steam generator being direct-fired, are also introduced into the hydronic heating system water. Before venting the products of combustion from the packed column, heat from these products of combustion is extracted in a secondary heat exchanger to preheat the combustion air before it is used in the direct-fired steam generator. Water is a product of combustion. Over time, this excess water will overfill the hydronic heating system if it is not removed. A water dump system is used for the removal of the excess water. By measuring the water removed and the fuel used in the direct-fired steam generator, an efficiency can be calculated for visual feedback. The products of combustion will also tend to cause the water in the hydronic heating system to become acidic.Type: GrantFiled: February 19, 2003Date of Patent: November 23, 2004Inventor: David P.
