The ReCon tankless commercial water heating system offers high turndown and efficiency, precise temperature control and long-term reliability in a small footprint. Delivering low cost- of-ownership, the ReCon family can reduce operating costs and help create energy savings in systems requiring more than 500,000 BTU/hr. The unique tankless design of the ReCon makes it a space-efficient and cost-effective water heating system. The unit eliminates the need for significant storage volume associated with tank-type heaters to buffer load change, while continuing to provide stable hot water outlet temperatures. Its small footprint allows the ReCon to fit through a standard doorway, as well as in compact spaces. A variety of venting options, including sidewall, through-the-roof and sealed combustion, provide installation flexibility.
