When we first started the demo my furnace and water tank were in a little closed in area. We think they tore down a wall to install the furnace I have been in the house for 7 years furnace was new when we moved in. water tank I had put in right after we moved in. I thought by taking down that little wall I would be able to open up the work area a bit. I hope these photos are helping because all this advise I am getting is really helping me. I want to do this right and safe and I thank you all for the input.
