Thanks everyone for the help. Sounds like I can continue to pull some heat out of the Hudson
River well into the winter. I wondered if the Marine
Air system has some sort of shutoff to prevent freeze-up? One of my concerns is leaving the system unattended and filling the bilge
with seawater if the condenser freezes.
Has anyone seen a condenser freeze in saltware (really it's the evaporator when in heat mode right?). Seems to me that between the salt
lowering the freezing point, and the rapid motion of the water through the system, and the latent heat that has to be removed for the water to change to solid, you'd have to have some pretty extreme conditions to freeze one up.
