Well I think what I've decided to do to heat my electric hot water heater is to utilize the domestic hot water coil in the boiler. The more I think about using a sidearm or plate heat exchanger just doesn't make sense when the boiler already has one built into it. I'll add a basic high voltage thermostat to the hot water heater to control a circulator pump. If I plumb it properly and insulate it well enough hopefully it will have thermal circulation and only need to use the pump under high demand. As for the type of piping I use...I guess i'll finally give in to the fad of using pex and give I a try. I'd prefer copper but just cant see spending the extra money on it. Also someone on here recommended spacing their boiler up off the floor to make it easier to work on when needed and I think its a great idea. Making a stand to sit the boiler on will be one of the first things I need to get started on. Another challenge ahead of me is fitting a large enough water to air heat exchanger in the plenum of my air handler. The plenum measures 11" wide x 19" tall. My plan is to get one that will fit the 19" height and then fabricate transition pieces for each side to accept at least a 20" long heat exchanger. I'm sure I will go through several sheets of cardboard before I get those pieces layed out properly.
