Hi Josh, I do like to have the option of good h2o pressure with my showers. I have a 4gpm water pump and the single exchanger just wont keep up with the water flow ( I can very the flow rate) and keep it warm enough. I couldn't come up with any reasons why I would need the space for anything else, so I quickly built a second exchanger and I can get really hot, non-circulated water at 4gpm at about between 1500-1700 rpm.

why did you decide to go with 2 heat exchangers?
