When checking into units to heat a 420sqft apartment, I checked with Heat Surge about their Amish Fireplaces being able to heat this area as the only heat, was told it would do fine. I did heat the unit last winter, but if left unwatched it never stops heating. No thermostat??? I have a $20.00 Holmes Heater that can operate on its own?? When I questioned this was told to use it as I would an electric fry pan DO NOT LEAVE UNATTENDED?? Where is the safety as the only Home heat?? In trying to get them to resolve this when I contact cust serv the only response is computor auto saying they will contact me?? After 2 or 3 wks of ignoreing I wish someone would get their ear??
