How often should you service storage heaters? mine stains the wall above the heater (darkens it) and leaves other black marks on the walls. Can anyone help?
I have never had one serviced. I had three for over 15 years and they were ok. I am now on my second lot. I am struggling with one at the moment that I think may have cut out but the others are all fine. As for marks. I vacuum the walls above with the brush attachment and then use a very damp cloth to wipe over. This seems to keep the dust down.
