VEVOR Heat Exchanger Water to Air, 20"x 20" with 3-Row 3/8" Copper Ports, 242 Aluminum Fins Heat Exchanger for Outdoor Wood Furnaces, Residential Heating and Cooling, and Forced Air Heating
Is it possible to connect several heat exchangers to extend heat to four floors?
I like to speak with someone who can explain me how this works.
Thanks
