I have a Biddeford Queen. 180 watts, single control. Lots of pros and cons regarding blanket versus mattress pad. Personally I do not care for the heat concentrated beneath my body with a pad. But an electric blanket does need a good insulating blanket atop it or heat just rises uselessly into a cool bedroom. Nice to preheat on FLAME ME! Crawl beneath the covers, then set the critter to a lower setting. I am warm blooded. I need HEAT! I figure the Biddeford would keep me plenty warm at 0C set at around six to seven. An electric blanket plus a Thinsulate blanket would be heaven on earth. I wear a comfortable knitted cap and sometimes a sweatshirt to keep shoulders and arms warm. This is in Baja California Mexico not Las Peñas, Michoacan Mexico.
Electric ANYTHING is amazing. An electric lady, though, keeps sticking her freezing feet against my back :(
