Wood heat. There is no indoor holding tank, but he does keep the house ~50 degrees or higher. It's a masonry house, so it holds the heat well. I will suggest stripping the insulation off his old tank and using it for a hot-line pre-heat holding tank. I can't absolutely say he'll go for it, but he's been pretty OK with my greening ideas so far.
