Regulating heat in fruiting chamber

I want to start growing mushrooms soon, but the problem I am having is that I am currently living in my parents basement until I start grad school. The basement isn't insulated very well and it can get pretty cold at times during the winter. How would I go about keeping the mushies at the proper temperature in a cold environment. I also need to keep the grow secretive because while my parents know about my activities they would not be comfortable with me growing in their house. Any suggestions on temperature regulation or secretive growing would be helpful
