<HTML>What you are calling an exhaust heat exchanger, on our Stanley cars we call them our feedwater heater. On the cars of 1910 to 1914, they were a factory installed item and reproductions of these are sold by Art Hart. On the condensing cars, I am not sure what all models had them, but they are found on most diagrams of the Stanley steam water systems. Although, I have a diagram of a model 740 that doesn't show it on it's diagram. On our 1914 Stanley, I have ran both with and with out the feedwater heater. The difference in performance is about a 10% gain with it operating. Weight? Not noticeable. On our model 735, it is a very heavy piece,(less than 100 pounds) and the only fault I find with it is that sometimes it is in my way when jacking the car up by it's frame. Benefits of a feed water heater? I wouldn't leave home with out one.</HTML>
