Ariston Thermo USA's HTP EFTU Condensing Firetube Boiler
August 3, 2020
Ariston Thermo USA LLC, the USA division of Ariston Thermo, has launched the new EFTU condensing firetube boiler for its HTP brand. The new EFTU series represents the next evolution of the firetube boilers. Featuring low pressure drop and resistance to combustion chamber fouling, the EFTU integrates an ECM pump and bypass, allowing for efficient operation and direct zoning. The EFTU features the same venting flexibility as the ELU range with vent lengths up to 150 feet. A complete range of heating only and combi models are offered. The combi models come standard with an ASSE 1017 mixing valve, assuring the contractor with what is needed to complete the job.
