Re: GBlist: Batch water heating



Ron Hughes mentined the old active/passive saying.  My experience began with
batch heaters (a breadbox design) but I tired of trying to guess whether the
sun was going to shine or not every day when I left the house.  Do you open the
insulated cover or leave it closed?

My solution the past 14 years has been thermosyphon systems, with bare
absorbers behind sloped glass either in a greenhouse or under large fixed glass
skylights.  Passive system, passive user!
