Do not use these Dimplex CXL18N as storage heaters as I want to control my heat manually. Very occasionally, when very cold use the heaters as convector heaters, for an hour only on a number 3 setting. Walls above both convector heaters are brown and electrician told me this was because I smoked and had a fluffy cat. My fluffy cat is not allowed in bedroom and I only smoke in lounge.
Brown marks on walls were there when we moved in and I knew the previous residents ffor many years, they neither had a fluffy cat or smoked! Am I missing something?

The air in our houses is full of dust particles, skin flakes etc. When the sun shines in through a window you can sometimes see it.

A light bulb in a table lamp sometimes makes the inside of the shade stain brown - particles in the room are lifted on a rising current of warm air. They stick to things they touch. The plastic lampholders particularly. You get a similar effect above your cooker but with airbourne grease and larger dust particles

Nothing wrong with your heaters - all you are missing is basic physics - smoking would make things worse - it does in my house and I get nagged for it.

It is also possible that the previous people did not decorate very often hence their brown walls.
