Sidearm heat exchangers are designed with natural thermo-siphon concept on domestic hot water side. Traditional sidearms are made of two bare copper tubes. Thus its capacity is decided by the length of sidearm-tubes and the heat transfer efficiency is very low. The stainless steel fin-enhanced sidearm increases heat transfer efficiency significantly by using finned tube internally, which has surface area five to eight times bigger than bare tube and produces great turbulence on system side. With a fin-enhanced sidearm you need only a shorter unit, but get bigger capacity and faster heating.

 

Copper Sweat Port Sidearm feature a “honeycomb” tube structure which offers as much surface contact as larger units.
