Most water heaters are installed in a closet or basement. These devices make sense because they are more efficient and effective when you don't have to deal with drafts in cold weather. This is especially true for tankless water heaters that do the job in place and need to supply hot water directly to a shower, sink, or other appliance. However, the Rinnai Value Natural Gas Tankless Water Heater is an 11 GPM model designed for outdoor installations and saving space in the home. This model from the well-known boiler manufacturer Rinnai can be installed in rooms without air conditioning, such as an attached garage, attic, or crawl space.
