Hello all - I'm trying to figure out the needed pipe size to install a heater in my garage. I currently have a 1" pipe that runs from the meter 26' to the first branch which is a 75000 btu furnace, from here the pipe is reduced to 3/4" and has 2 branches, one 1/2" to a 40000 btu water heater, one 1/2" to a 20000 btu dryer, and then ends at a 15000 btu stove.
What I'm trying to figure out is if I can continue the 3/4" pipe to the garage and add a 45000 btu heater. Based on what I have figured out I should be able to do this, it would be close (granted not everything would be running at one time) but I'm having a hard time due to the pipe being reduced, I'm not sure how to factor that into the math. Any assistance would be helpful.
