The continuing growth in popularity of tankless water heaters can be boiled down to three simple causes — uptime, space savings, and energy efficiency — Madison Phillips, senior manager of global product management at Rheem, writes in Plumbing & Mechanical Engineer.

“Equipment downtime is costly, whether or not it is planned, and hot water is very often a non-negotiable element of either the customer experience (i.e., hotels, multifamily homes, college dorms, office buildings, etc.) or production process (i.e., restaurants, manufacturing and more),” Phillips writes. “When it comes to water heaters, some business owners and building operators might see these factors as reasons to stick to the traditional, tank-type water heaters that have done the trick for decades. But if these considerations are assessed objectively, they all actually play into the three greatest strengths of a tankless water heating system.”

Because tankless water heaters are scaled up by combining multiple units, they provide redundancy for buildings in the event one of the units goes down for repair. They’re smaller than normal boilers or tank-type water heaters, so facilities don’t have to waste an entire room to accommodate a water-heating system. And condensing tankless water heaters operate only on demand, creating significant energy savings compared with traditional water-heating systems.
