Rheem is the creator of highly prestigious tankless water heaters that thrive in even the most demanding use case scenarios. Boasting advanced control and self-diagnostic systems that ensure top performance and safety, Rheem’s tankless units can deliver uninterrupted hot water flow at efficiencies that surpass 94%, and at a satisfying flow rate. The company offers both electric and gas units, at a max power of 27 kiloWatt, and the best low-activation flow rates in the industry. Another important feature is the built-in condensate neutralizer that is found in the more costly models which reduces the installation and deployment time and cost, and increases the energy efficiency even more.
