Query: Only last one season

Look for a different heater. These heaters only lasted us one season. We purchased two of the units last winter for our kid's bedrooms. They worked quite well at first and then began to switch off. I searched for a solution only to find postings from other frustrated customers that could not remedy the situation. From what I could gather it seems the problem is with the digital electronic thermostat. The replacement parts are not available making the unit fit for the landfill. That's not good because it was fairly expensive and it definitely should not be a disposable item.
