High Quality Fin-Enhanced Sidearm Heat Exchanger is designed with the 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.
Made of 304 stainless steel, fin-enhanced sidearm increases heat transfer efficiency significantly by using a finned tube internally, which has surface area five to eight times bigger than bare tube and produces great turbulence on system side. With fin-enhanced sidearm you not only need a shorter unit, but get bigger capacity and faster heating.
Ideal for residential heating and plumbing, solar hot water heating and outdoor wood furnace applications.
