I have friends who own a single-family home and made the choice to install their new tankless outdoors. And I have another friend who has a condo and installed hers indoors (no choice in this case, condo rules do not allow outdoor mounting). For the condo installation, it replaced a traditional tank water heater and there was some additional work required for venting. Aside from cost, are there any safety or reliability factors that favor indoor vs. outdoor installation?
