I need help determining whether I can install a tankless heater with my existing gas line setup.
I have a 17 year water tank heater (75 gallons) that is in the attic (it was there when we bought the house) and that is going to be impossible to remove without cutting it into pieces (incredible how they set this up, but that's besides the point of my question). I want to be proactive and start planning on how to replace it.
We cannot replace the current heater with another water tank heater so I am exploring whether we can install a tankless heater in the same location. Two companies told us we need a dedicated gas line, and two companies told us the current gas line is ok.
We have a 1 inch gas line going up to the attic, being reduced to 3/4 to feed one of our furnaces and the current water heater. This main gas line has a total of 2 furnaces connected to it (1 in the attic to heat the top floor, another furnace in the crawl space to heat the lower level, and one gas stove in the kitchen (5 heads).
We have 3 shower heads and 2 1/2 bathrooms. We live in the San Francisco area, so the 2 furnaces don't run at the same time very often.
Can I install a tankless with the current gas line setup?
Thank you for your help!
