We bought an oil heater a month ago. It was turned on no more than 10 times. It turned out that it was originally defective - the temperature controller did not have a limiter when turning to the right. Since it was turned more often in the direction of increasing the temperature (to the right) than in the direction of decreasing, this regulator simply unscrewed like a threaded nut, and something fell off inside the electrical part. Now the temperature is not regulated, and the heater does not alternate heating and shutdown.
The store said that this is not a warranty case, it turns out that I caused mechanical damage to the heater! It was necessary to bring it to the store before the regulator unscrewed, and inform that there is no limiter!
And how am I supposed to know that the limiter should be there? Nothing is even written about him in the instructions. The operating instructions - paragraph 7 says: "Turn the thermostat clockwise to increase the temperature, and counterclockwise to decrease the temperature. " So what rules did I break when using the device? What other parts inside the device should I determine the presence or absence of?
I will not recommend Sulpak to anyone!
