Ever since last winter I have been thinking about building an Air Handler with a water-to-air heat exchanger. And now, since I have the Hitzer 75 with a huge internal water-jacket, I have the means to try out my idea.
The second option is a single cast-iron radiator with the Hitzer plumbed to the radiator and then have the return water travel through a slaved Hilkoil (installed in my Leisure Line Lil' Heater) which would pre-heat the return water before it goes back into the Hitzer starting the loop all over again.
Which method is more efficient, plumbing a single large cast-iron radiator just above the Hitzer on the first floor or custom make an air-handler. I could even use the coaltrol to run the convection fan for the air-handler, turning it on and off based on temps.
If I have two radiant stoves located in the basement, and I want to move more btu's upstairs instead of wasting them in the basement, is a radiator or air-handler an improvement?
