My present plan for my, as yet, unstarted Cozy (unless one counts completion of the shop facilities) is to mount two cores - e.g. the Frigidaire EV6709 - in tandem, with the water flow going first through the rear core and then through the front one. The delta-T won't be *ideal* in either core, but it will be substantial. I just have to work out a plenum that allows no air leakage between the cores. Still trying to keep the expenses down, without being "cheap". I'd hesitate to assume that you can put two evaporator cores in series without having excessive pressure prop. Might be good to run some tests first. Al
