Yep. I still have a problem of safety measures (or should I say, lack thereof)
for detection of termination of propane or water, as well as no thermostatical
control. The water actually adds another point of failure. Another problem is
the high current used by the heater blower (5A?).
Actually, I kinda like the vented propane catalytic heaters but:

1. No local vendor here.
2. Propane isn't popular here. I was thinking about a fuel (widely available
at any gas station) or butane based solutiuon.
