One of the easiest ways to augment heat is to use southerly facing windows as passive SOLAR HEAT CATCHERS. This uses a plan similar to the outdoor hot box collectors seen at such sites as listed near the end of the article –but is done indoors and in an existing window. No carpentry needed! While outdoor mounted heat boxes do work, a much easier heat collector can be constructed with aluminum foil, tape and flat black paint using your south facing windows. We adapted the concept to fit a cheap budget. Just tape the collector over the window! If you want to leave the bottom of your windows exposed for light, just make your collector on the top of the window or vice versa! With this method we have cut our winter heating costs (we have all electric heat!!!) by over one half. It is very simple to do and very inexpensive for the benefits reaped. And it uses free solar power! We have heat catchers in all our east, south and south-west windows placed in back of existing drapes and blinds.
