Hubbell electric tankless water heaters have many advantages over the tank-type heaters. Hubbell tankless are space-saving units that are mounted on the wall or installed under the sink and cabinet wall, so the floor space can be used for something else.

Due to the small, compact and lightweight design, they can be installed almost anywhere; closet, utility room, under the sink, crawl space, and thanks to its stainless steel exterior, also in the garage, attic, high traffic places and locations with the wet conditions. These units are designed mainly for the indoor use, but with the appropriate enclosure can be installed outdoor too.
