Ultimately, the answer is yes. Assuming that it is economically feasible, in most cases a tankless water heater can be installed in many locations, including the attic and garage but also in interior home closets, utility areas, workshops & workspaces, recessed into the brick exterior, or on rooftops (usually commercial applications), as well as others. In all honesty, Earl’s Plumbing can do just about anything you want to do plumbing-wise, as long as you’re ready to spend the money. But we like to think of ourselves as good partners and can sometimes figure out alternative solutions to get you the end result that you want without breaking the bank. When we get this question, it is usually an after-the-fact response to a problem that has happened previously, such as a ruptured tank heater in the attic that flooded the house. We always tell our customers that they must be proactive with tank heaters that store 100 gallons of hot water above their living area. They do not always take our advice and occasionally wish they had. But we can offer solutions that often make more sense than a costly relocation.
