I am purchasing a new home and have an issue with the utility room/laundry room. There is not enough available combustible air in the current room. I believe I have to install a high and low vent for this, therefore, I figured that I need about 146 sq. in. for each louver.

There is a link to the room attached, is it safe to have the furnace and water heater so close to each other?

What type of vent/louver should be used. I live in the Northeast and don't want pipes freezing.

Thanks for any help

12x12 inches =144 which should do. Go to HDepot and see what grills they have. Should have wide open grills with no louvered slats which decrease the airflow. Heating or sheet metal suppliers may have white grills for that purpose also. OK to have them that close. Combustion air comes from inside the house and the grills go in the furnace room door. No need to get a comb air pipe from the outside unless the house is new and very airtight. Most older homes are leaky enough around doors and windows to let enough air in. Get 2 high quality CO detectors and put 1 near your bedroom and 1 in the stairs to the basement.

Another concern is the dryer. It will pull a lot of air out of the room and send it out the vent when running. You might consider replacing the door with a louvered door instead of just adding some 12X12 vents.

One thing I left out was that the door goes into a small mudroom. There isn't much chance to put another louver on the door into the kitchen.

The room is also on the first floor and not in the basement.

Would a fan-in-a-can/air-in-a-can work. I believe the requirement is 1cfm/2400btu. That is easily attainable with a 4" fan and would keep the room warmer.
