OK All,
I admit to getting older but refuse to grow up! That being said I have decided to build a heater as I have frozen my *** for the last time.
I have everything to build a very compact heater and a 3 speed fan set-up. I plan to draw intake air from the floorboard area inside car so no fumes are picked up. I do not want visable vents so will hide behind dash.
Who has a heater to recommend how many outlets and where should I aim them? Is it important to be able to turn off passenger ducts? Any other considerations I have missed, please give me your thoughts and experiences so I can learn from your set-ups? Where did you mount ? THANKS ALL
