Recently completed and moved into my new office, which is a 100 SF space adjacent to my shop. It's a fairly airtight drywalled room with a couple of very good windows, and the door is weatherstripped to try to prevent dust from coming in from the shop.
I just installed an electric heater, a Convectair 'Mezzo" (see http://www.convectair.com/us/produit/mezzo.html#fiche ) that has an aluminum block heating element. When I first turned it on it smelled a bit, which was unsurprising--hard to describe the smell, not quite a burning smell but easily identifiable as something electrical). I ran it at full for a few hours to try to burn it off.
A few weeks later it seems like the room still smells and sometimes I notice a low grade headache if I spend a few hours working in there. The heater doesn't run very much because it hasn't been that cold, but it does run a bit.
Does this sound familiar to anyone? I assume the smell is a surface coating from the manufacturing process that has to burn off. I could also be getting a headache from hearing about so many new Federal bailouts on the news.
