Hello We are currently renovating our first house. As new homeowners we are trying to make sense of all the advice we get from different people. After putting in 2 new baths, we need a larger water heater than what we currently have. However there is no physical room to fit one. We then researched and decided on a tankless water heater, in addition to the existing one. However our builder says we cannot fit one due to venting restrictions - i am referring to a gas tankless water heater. Can someone please refer me or help me find out, what are the restrictions in the code regarding venting a gas tankless water heater? my builder says it must be 8 feet away from a window which basically restricts every possible place in the house... we are looking to place it indoors on an outside wall and vent to a side wall. can someone help me and tell me where am i allowed to place the vent and what are the restrictions on it? thank you BTW I live in Bergen county, NJ.
