Hello All, I am hoping some of you "Heat Grinches" out there have had the same thoughts I have about keeping all that heat going out the clothes dryer vent in the house where it belongs during winter months. I have had this thought every winter for several years but have never came up with a good system to re direct the heat into the house when needed. I have looked for a simple diverter switch/box that would allow the home owner to divert the heat into the house during winter months and then in the spring back outside but have never found one. Has anyone solved this problem? Please let me know if you have any ideas on where to find this type of diverter or how to make one. Any and all input welcome.
