500 watts would be sufficient, if not ......

Previously I had another device with 500 W for a guest bathroom about 6 sqm in use.
This 500 W were always sufficient. After nearly 10 years, it was now broken.
Now I have decided on this new oil radiator.
Very compact dimensions and 500 W.
Now, even after half a day, the new device was now in operation, it remains relatively cold in the room.
We had mild outside temp. +3 degrees.

The stated 500 watts would be sufficient
unless a thermal switch inside, the heating before the
would switch off variable Themostaten between.
This switch has certainly its meaning,
He throttled the temperature from overheating and burning up when touched.

I assumed that the specified output of 500 W
a heating capacity of 0.5 corresponds to KWS
but by the time between switching off by the thermal Schaler,
remain estimated. 0.25 KWS heating. (The adjustable thermostat has only effect in max. Position)
Therefore, the device in my case, only ("geradeso") is suitable as frost guard.
