John Ruhnke, owner of JR’s Comfortable Heat, is a  Past President of the Inventors Association of Connecticut (IACT). We have developed an air eliminating circulator for a hot water heating system called the Autopurger. John received some grant money to procede further with the Autopurger project. We have built three working prototypes (See picture). John Ruhnke has received Three patents. Two are on the Autopurger Project and one is on the Overall Efficiency Project. 

In the Overall Efficiency Project, John Ruhnke and Robert Distinti wrote a formula to calculate Overall Efficiency in a heating system. They received a patent on the use of the formula in a networked energy control or database. There has been some serious interest in both projects.
