Thanks to all that helped with my questions. I did a self install and all went great. I did hook up the Hot water heater to my coil in the furnace. I already had the lines run so I will give it a try. If it doesn't work, I will do a exchanger at the hot water heater like some of you suggested. When I fired it up, the water in the tank was 72 degrees. 50 minutes later, the water was 180 degrees. I came inside the house and took my heat gun and checked all the vents. Most were 95 - 105 degrees with a couple at 110. I only ran it for a few minutes as it was 80 degrees here today. Tonight is suppose to drop in the 40's and stay in the 50's for a couple of days. I plan on getting some temp readings at the return line on the heat exchanger just to see what the drop will be and I also plan on posting some pics. One thing I would like to add is a light (maybe red) that will come on when the fan is running just so when I look out the window, I will know if it is running or not. Any add-on suggestions would be greatly appreciated. Thanks again!
