The efficiency of the new space heater would certainly benefit from a fan right there, but running an electric fan overnight – though I don’t think it’s unfeasible – is just instinctively bad medicine in a small solar power system. I wondered what would happen if I parked that woodstove fan there.
What happened, overnight, is nothing at all. I woke at about 3:30 while the heater had been on for a while and it was just sitting there.
This morning while the fan was on the woodstove and spinning merrily along, I put it back on the space heater which was also burning. It continued to run, very slowly, I think because the fan body was already hot. As it cooled the blades ran slower and slower but never entirely stopped. It certainly wasn’t doing any good, though.
I’m impressed with that heater’s design. We went way overboard in protecting the wall from its heat, since it’s built to send heat out the front and nowhere else. The top gets uncomfortable but never painful to the touch, the rest of the case barely heats up at all. Inside the case is a different matter, of course. It came with a rubber hose to connect the propane bottle to the valve, and that was a dangerously bad idea. It gets really hot inside the case near the firebox. But having done a few dumb things with propane over the years, I knew that up front and bought iron plumbing for it before the permanent installation.
