To have a go green heating system simply means that you understand that it consumes a large portion of your energy so you might as well do some necessary changes to reduce energy use. If you plan to leave the house, a go green stance is to never let the heating system run at the same temperature as if you are at home. Keep it low; better yet, go green and turn it off. You are not needing it anyway. If for instance you do not want to enter cold home, you can set up a remote control heating system or a programmable heating system. In this way, you do not have to leave the heating system running all day. All you have to do is to set the time when you want your heating system to work and you will go green and save a lot of money as well.
