Negative Positive
Title: Only one problem...
Review: I liked the heater very much at the first year. All I need is a quiet convection heater without fans.But starting from the second year, it started to give cracking sound when heating up and cooling down. So when you set the thermostat to a temperature, the heater will make noise all night long because to keep the temperature at the set point, it will turn on and off every a few minutes... you get the idea. Probably something inside is not assembled well...
