Have had this portable baseboard for several years. At first, it worked as advertised. Then, the thermostat gave out and I called for service. Their response was to send me a new thermostat and an instruction sheet. They advertise a "lifetime warranty" which apparently means, we send you the parts, and you fix it yourself. Exactly one year later, the unit began to smoke and emit an awful smell. Again I called. Again, I received a box of parts to replace myself. Three parts this time. This fix included the need to snip and wire and make another half-dozen or so new connections. Doesn't this seem dangerous to anyone else? What happens if you get it wrong? To me, this is NO warranty. This is NOT customer service. For as expensive as these units are, being told to "fix it yourself" is just absurd. I would never buy another Hydrosil. There are too many other options out there.
