Did the heater for my little garden shed use with solar panels. Have a 1000watt voltage converter which immediately gives up the ghost when I turn on the heating. Testing has shown that the device ca 1040 watts starting current and the 10 seconds required. The reason why I forgive only 3 stars. Otherwise, I have you tried at home again. A 12 square meter room I got warmer in 15 minutes almost 4 degrees.
